The Differences Between Undergraduate and Graduate Writing and Research

On the face of it, the differences between undergraduate and graduate level writing and research should be rather obvious. After all, we expect more of our graduate students than we do of our undergraduate students. Education is a progression, something we build upon and improve upon as we travel through the years. However, just because this makes intuitive sense does not mean that the actual differences between the written products of each level of study are that clear. After all, we expect the grammar, punctuation, mechanics, and other such issues to be correct in both cases. So let’s examine some of the differences that should be in play when comparing the two.

First, graduate level students are expected to think on a higher level than undergraduate students. This means the vocabulary should be more sophisticated; the thoughts should be better developed and deeper; the analysis should be stronger; and so forth. The topics don’t necessarily have to be very different for each level, but the approach to, and handling of, those topics should differ. For example, an undergraduate and graduate student could each write a paper about global climate change. But while the undergraduate level paper might talk about Gore’s “An Inconvenient Truth,” and discuss how that movie made some excellent points, the graduate level paper might reference a UN white paper on the matter, and analyze what effect that paper has had upon international policy.

Second, graduate level students are expected to have read and written about a much wider array of subjects, and learned about a much larger variety of theorists, scientists, and other scholars in their particular field(s) of study, than are undergraduate level students. As a result, graduate level papers should include a much deeper referencing of, and building upon, those previous thinkers. It should be clear, not in a name-dropping way, but in a way that shows a true integration of a wealth of knowledge, that the graduate level student has integrated previous work and is building upon it.

Finally, graduate level writing and research (but especially writing) should show a much greater percentage of original thought than does undergraduate level writing. In the early college years, students are absorbing a great deal of knowledge about their chosen area(s) of study. It is not to be expected and in fact, it is often frowned upon that students at that level are thinking original thoughts about their disciplines. For example, it would not make sense that an undergraduate would believe he had the answer to a philosophical dilemma that had plagued philosophers for centuries his depth and breadth of knowledge in philosophy would simply not be there. However, by the time people are graduate students especially doctoral students it is expected that they have absorbed that knowledge and are starting to think their own thoughts that extend that knowledge base. Of course, graduate level students continue to research what others have discovered before them, but again, they are expected to contribute to their field(s), while undergraduate level students are not.

Certainly, there are other differences between these two types of writing. However, the basic idea is that much more is expected of graduate level students in the way of sophisticated writing and original thought than is expected of undergraduate level students. While not all graduate students are free-thinking geniuses, and while not all undergraduate students are mere sponges, these general guidelines apply.

One-On-Ones The Most Powerful Management Tool

The regularly scheduled one-on-one (O-o-O) has been called the most powerful management tool available. Yet many managers are not having regular one-on-one meetings with employees, and it impacts the work environment.

To make the O-o-O effective, it should be regularly scheduled (every other Tuesday at 9AM or every Monday at 4PM or whatever works). It should be rarely missed and its primary focus must be on the employee and their performance. Notes should be taken by both the employee and the manager. The meeting will likely last no more than 30 minutes with 10 minutes for the employee, 10 minutes for you, and 10 minutes to focus on the employee’s development.

To prepare for your next O-o-O with an employee, ask yourself a few questions:

What positive feedback can I give the employee? What commitments did I make at the last O-o-O that I need to follow up on? What commitments did the employee make at the last O-o-O that we need to follow up on? What information have I received from outside sources that I need to share with the employee? What is currently on my plate that I can delegate to the employee that might be helpful to their development?

Some managers use a standardized form to track the outcomes of each O-o-O. The format might include notes you take from the employee’s update, notes you prepare for your update to the employee, and a list of agreements or follow-up items. The fundamental goal of the O-o-O is to maintain an ongoing dialogue with each employee about:

performance expectations resources the employee needs to meet the performance expectations feedback on the employee’s progress development opportunities the employee is pursuing

The O-o-O meeting is notably the most powerful management tool available. It is a no-cost, personal way to boost morale, enhance engagement, and improve performance. So when is your next O-o-O?

The Role Of Copper Nanoparticles

Ultrafine particle material is a powder of particle size in 1 to 100 nm, it is also known as nanoparticles. The nanoparticles have the effect of small size, large specific surface and macroscopic quantum tunneling effect. Thus it shows good performance that micron powder does not have. Because copper nanoparticles have large specific surface and big number of surface active centers, they become excellent catalysts in metallurgical and petrochemical.
In automobile exhaust purification process, the nano-copper powder can be used in part as a catalyst instead of the precious metals platinum and ruthenium, toxic carbon monoxide into carbon dioxide, nitric oxide into nitrogen dioxide. With the development of the electronics manganese powder industry, prepared by the nano-copper powder superfine thick film pastes used in the LSI plays an important role, while the price than the precious metals silver, palladium powder, inexpensive, and has broad application prospects.
Hydrogenation and dehydrogenation reactions of polymers, nano-copper powder catalyst has high activity and selectivity in the acetylene polymerization is used in the production of conductive fibers, nano-copper powder is very effective catalyst. Ultrafine Copper is an indispensable basic raw material of good conductivity, high strength of nano-copper. Because of its excellent electrical properties, are widely used in the conductive adhesive, conductive coatings and electrode materials, the study found that in recent years can be used for the production of catalysts, lubricant additives, and can even be used for treatment of osteoporosis and fractures.
The development of nano-copper powder is a potential copper and its alloys revolutionary change has important theoretical significance and practical value. Copper nanoparticles in the development stage and its extensive use of copper nanoparticles have better market value and market outlook. The reducing agent used include formaldehyde, ascorbic acid, sodium hypophosphite, boron, sodium chloride, hydrazine hydrate, but these reductant some highly toxic, and some reproduction is poor, some costs are too high, as well as the reaction process easy to introduce other impurities, therefore, to find a more appropriate reducing agent or compound reducing agent, and study more ideal reaction system to become an important research topic of the nano-copper powder preparation. In addition, due to the smaller particle size of bronze powder (FCu 663) nanoparticles, the surfactant large, easy to reunite, and the powder surface is easily oxidized to Cu20, how to improve the dispersion of copper nanoparticles and how to prevent the copper powder is oxidized is also an important research direction.
Currently, the industrial production of ultra-fine Materials and methods: freeze drying, precipitation transformation method, phase synthesis method, ultrasonic method, the hydrolysis method, mechanical alloying technique, homogeneous precipitation method, restore a protective law. The above method and some require large equipment and some complex, some preparation costs are high, and some qualified rate and low yield. And liquid phase chemical reduction method of copper nanoparticles has its unique advantages, such as simple equipment, arts short process, a small investment, production, low cost, easy to industrial production.
Nanometer copper lubricant additives are a new type of lubricant additive products basing on nanotribology and nanotechnology as theoretical guidance. It has excellent antifriction and energy saving efficacy. Adding nanometer copper lubricant additive to automotive engine lubricants, the engine start-up current can be reduced and it increased cylinder pressure. Engine using the additive for some time, they form a protective film on the cylinder liner and piston ring. Once the lubrication system failure, the car is also safe driving for a long time, this is of great significance in the military. In addition, the nano-copper powder can significantly improve bone density, increase fracture resistance and improve the morphology. There are significant preventive and therapeutic effects for osteoporosis.Source:http://www.mhcmp.com

How Caulks And Sealants Are Used In The Modern-day Construction Industry

A trip to your local home improvement store can be an overwhelming experience for the average person, especially if you’re trying to figure out which caulks and sealants to use for your exterior home improvement project. Unlike the interior, the exterior faces high UV exposure, extreme temperatures and the requirement to stay 100% waterproof.

When you’re dealing with silicone caulks, you have a non-paintable surface, with poor UV performance. Although water based and latex caulks have good paintability, they also have high shrinkage, poor elasticity and poor UV performance. Synthetic-rubber (polyurethane) sealants and tri-polymer sealants (silyl terminated polyether sealants) can do it all: paintable, great moisture sealing, no or low shrinkage, and very good UV resistance. Many are also pre-tinted in popular colors. These include the popular NP1 (polyurethane sealant), Sonolastic 150 VLM, and Novalink sealants.

All of these sealant and caulk materials are heavily advertised and marketed with super flashy packaging, labels and all kinds of fancy logos. If you’re looking for a high performance caulk or high performance sealant, you can literally be confronted with hundreds of brands and companies that claim to have the best product for your needs. So what can you do, when you are bombarded with all kinds of choices?

Each brand of caulk generally has its own special and unique qualities. Although, it is in your best interest to read all of the labels and also follow the company specifications, for the use of the caulk and sealant, the very thing you want to know may not be found on the labels of the containers at all! Many of the best products are architectural / commercial grade and not generally available to the public.

Sealant was originated through the needs for exterior finishing in the home building industry. Caulk was originally a term that was used to describe the sealant material used to build boats. Many companies and manufacturers these days are using caulk as an all-purpose word to describe paintable interior grade products. Sealants by definition have at least /-25% elongation capability over a long-term period and are UV resistant. Advanced sealants are 100% solids and offer up to 100% elongation.

Most of the general public use caulk and sealant interchangeably to serve the same basic purpose, which is to fill gaps between building materials and to shield materials from air and water.

Although sealants and caulk work the same basic manner, they both also fail for the same basic reasons. There are three major types of caulk failures that you will encounter. These are substrate, cohesive, and adhesive. The bond that is put between the substrate and the caulk can actually fail, making the caulk tear and break down. Caulked joint problems are also very common and are usually due to the substrate not being effectively prepared or using the wrong product all together.

So, before you choose a certain kind of product, you want to really think about how you will be using it and for what purpose. You will also want to consider the area or location you are going to apply the caulk or sealant.

For example, if your intent is to seal the area around the base of a toilet, sink, bathtub or shower, it will be imperative that you purchase a product that both mildew-resistant and durable enough to survive scrubbing and chemical cleaning. If your intent is going to be to use sealant or caulk between wood clapboards and vinyl windows, then you’ll need to purchase a product that is able to bond very well to both types of materials and is weather resistant.

You will also want to keep humidity, temperature and moisture in mind when you are shopping for caulk or sealant. Water-based caulks not recommended for outdoor projects, because these products do not withstand the hot-to-cold and cold-to-hot weather changes, as well as other harsh weather situations. If you are living in an area that is below 50F during the time you need to apply sealant, then you’ll probably want to use a silicone sealant, instead of polyurethanes, because polyurethanes are very difficult to apply in chilly conditions.

Other Applications: For sealing skylights, glass domes, greenhouses and such, Sonolastic Clear 25 is a popular product. For Kynar or siliconized paint finished metal roofs, a special sealant formulated to seal to these surfaces is a must. Products such as Duralink are popular. For repair of swimming pool tile grout lines, polyurethane sealants are excellent. Products like Ultra provide a very durable seal, which can survive in areas where grouts fail quickly. Ultra is also used as a pickproof sealant in security applications.

To the delight of many, who prefer the do-it-yourself project, certain caulks and sealants can be color-matched to paints, tiles, grout, wallpaper and even carpeting. The beauty of these products is that they can be color-matched while they are still in the product tube. NP1 is also available in many popular pre-formulated colors. Any good home building products store will be able to help you color-match your caulk and sealant to your desired color. Once the caulk has cured, then it will precisely match the color you were seeking to acquire.

In summary, let’s review your options again:

1. Water-based caulks are the easiest to work with. They have a smooth, thin and consistent flow, and they are easy to apply with almost any tool. These products cure quickly, have very little odor, and the clean up is easy with water.

2. Silicone caulks and sealants are good for interior or exterior areas, which will not be painted and are good for areas that will be exposed to extremely cold weather, certain metals, and glass. Silicone materials do not repair well (nothing wants to stick to cured silicone material, not even more silicone)

3. Synthetic rubber sealant is best used for areas with high movement and dissimilar materials. These materials can be painted and are designed for long-term exterior exposure. There is also less chance that the synthetic rubber bond will break during movement. Common applications are roof tile repairs, roof moldings, and roof to wall sealing, window frame sealants, and doorsill sealant.

4. Self Leveling Expansion Joint Sealant, such as SL1 and SL2, are used to fill and seal the expansion joint gaps in concrete and driveways.

5. Tri-Polyimer sealants, such as Sonolastic 150VLM are the next generation. Although somewhat more expensive, they offer superior exterior performance.

6. New Hybrid products are available that defy all classifications. Using these kinds of sealants can yield a lot of surprises, so be sure to read the instructions carefully. Some of these products tend to expand upon drying, so it is best to test them out in an inconspicuous location before actually using them on your project.

Print this article and take it with you when you are shopping for caulk and sealant. Review it and then follow any instructions on the containers of the products you buy. It is our hope that this quick tutorial will help provide some clarity on exactly what products you should buy for your home improvement or home construction project.

Beware Scam And Fraud When Ordering Marble Granite Stone Directly From China

Granted, in the past few years, China has become an important exporting country for marble, granite and other natural stone products. It is little doubtful that China is capable of supplying high quality and low cost building and carving stones due to its low labor costs, rich natural stone resources and internationally recognized traditional workmanship.

There are many excellent marble granite fabricators and stone carvers in China. However, a large portion of stone products have been imported to the States by various exporters in China, although they claim “factory direct”. Among these exporters, some are large firms, some are one-man business and some even do not exist at all.

With fast growing of international trade, more and more stone dealers, contractors and even homeowners have been ordering or trying to order stone products directly from sources located in China. Most people believe by doing so they would get much better deals comparing to buying from a vendor in the States. That might be right to certain extent. However, this could expose a buyer to great financial risks as the buyer has very few leverages on a transaction conducted between two countries. I have heard of many undesirable experiences and disastrous stories associated with ordering stone products directly from China.

I am not trying to be scary. The situation is indeed true and the incidents are absolutely not isolated. Let’s first review the ordering process that most international trades would follow.

As the first step, you will search for a number of stone suppliers in China through Internet. You don’t know anything about them other than whatever they advertised themselves. Then you obtain a number of comparison quotes for the stone products you are in the market for and decide to deal with one of them. Then you sign a sales agreement with the supplier and wire transfer a deposit (typically 30-50%). After the deposit fund leaves your bank, the only things you can do are waiting for production to be completed in China and, praying for the order to be shipped on time and in conformity with what you specified. Finally, you have pay for the full balance before the shipment is delivered to your site.

The problem is right here – you will virtually lose control of the ordering process after sending the deposit oversea. The supplier that took your deposit may choose to proceed in the following three ways:

1, They will produce and deliver your marble granite order as per the terms in the sales agreement. This would be an ideal result with a happy ending. You get what you need with great savings.

2, They will produce and deliver your order in an inferiors way. This scenario happens quite often. For example, different marble granite and other natural stone materials have significantly different costs. Using the materials with lower costs will generate additional profits for them. When you receive the shipment and find out what you get is not what you wanted, what can you do? Basically nothing. They have your money. They may choose to do anything or nothing. Even if the discrepancy is discovered before the order is shipped, you will still find yourself in a difficult situation. You may ask them to redo the order, but the chance is rather slim. You may cancel the order and demand a refund of the deposit, haha, canceling order is okay; getting money back? good luck. Here is a real story. I know a buyer who paid over $2000 to buy a precious “jade vase”. When the shipment arrived, she discovered the vase was made in regular “onyx”, which has a value of less than $200. What a loss!

3, They will grab your deposit, close bank account and disappear completely. They may change the business name and do the same trick again and again. But you will never be able to track them down. This group of “suppliers” are running scam business and have caused significant financial losses to American consumers.

Therefore, buyers should be extremely cautious when ordering marble granite and stone products directly from the suppliers in China. Here are some important tips.

1. Always do some comprehensive researches on the background of potential suppliers in China. This may be difficult to do, but you must do. You may request trade references from their existing customers in America. You may also contact local chamber of commerce in the city where the supplier is located to validate their business nature and credit history.

2. If you order is large enough, you may want to pay a visit to China before finalizing the order to meet the supplier(s) in person and to see their manufacturing facilities.

3. Make sure to have all specifications included in the sales agreement, the more detailed the better. Also make sure to state “no substitue material allowed” in the agreement.

Let me give you an example. Italian White Carrara is a well-known marble with high value. There is also a type of white marble quarried in China, namely Beijing Off-white marble or Hanbaiyu, that can have very similar color and textures to the Italian White Carrara. Many suppliers in China, especially carving stone vendors, often use Beijing off white marble to replace Italian White Carrara and argue that Beijing Off White Marble is also called “white Carrara” in English. The problem is that the cost of Hanbaiyu is only fraction of Italian White Carrara. How to avoid this type of trick? Easy, make sure to include “Italian” before “white carrara” and indicate “Chinese version of the material” will not be accepted.

Similar situations also exist in granite colors. For example, there are two versions of “Emerald Green” granite. One is quarried in China and the other has an European origin. They are quite different in terms of texture and price.

3. Try to use “letter of credit” (L/C) as the form of payment. It is the fairest transaction methods for both seller and buyer. Both parties are financially protected if they are determined to fulfill respective obligations as set forth in the sales agreement.

4. Stop and think again when you see a quote containing prices that are too low to believe. Most scam businesses tend to use extremely low prices to attract buyers or more accurately, the deposits.

5. When comparing the quotes you received, make sure to compare apple to apple. Suppliers in China like to use some vague pricing or delivery terms in their quotes so they can impose hidden charges, i.e., increase your costs, later.

For example, you will be surely happy with total costs of $3000 for shipping a container from China to Buffalo, New York, including ocean and land freight, duty and port charges. But wait, there is a line in small letters, saying “shipping costs are estimate only”. As the commonly used trade term is FOB, or Free On Board, you as a buyer are responsible for all logistics related expenses anyway; a supplier can quote anything to make their grand total appear competitive. How much truth in that $3000 estimate? Almost none. But I have seen this figure in many quotes sent out from suppliers in China. The average value of a container load of granite and marble is right around $30,000. The duty alone will be almost $1500. Therefore, when comparing the quotes, make sure to compare the costs of goods only, unless what they quoted is “CIF” (costs, insurance and freight, in contrary to FOB) “to-door” delivery.

6. It is strongly recommended to place your order with an accredited marble granite stone importer in the States who is dealing with manufacturers in China directly. You may need to pay little bit more (5-15%) for your order, but this certainly will save you lots of hassles and mostly importantly, your financial risks will significantly reduced.

In-car Dvd Player Options

Of all the technology options you can add to your car, the one that knows no age limits is the in-car DVD player. With one of these devices onboard, kids who get fidgety 30 minutes into a 300-mile trip no longer mind traveling by car, and parents can concentrate on driving — or having an uninterrupted conversation.

According to the install position, there are six main styles which popurlar in the market today, Flip Down DVD Player, Sunvisor DVD Player, In Dash Car DVD Player, Portable DVD Player, Double Din Car DVD Player and Headrest DVD Player. Then let me inform the pros and cons one by one as follows.

Flip Down DVD Player

It also being called Car Celling DVD Player, Roof Mount DVD Player or Overhead DVD Player. According to these name, do you know its install position now? Yes, it should be hanging on the top of car. Therefore, it requires a large space in your vehicle. Usually it is rarely used in a small car. Most of them are installed in commercial vehicles such as MPV. So small and economic car models are excluded.

Sun Visor DVD Player

Like its name, the display of this DVD is in the sun shield of car. The size and thickness of the sunvisor display may be different with the original in your car. So the beauty and the outcome will be a little lacking for this entertainment system. While they are normally less costly than other dvd players.

In Dash Car DVD Player

The in dash DVD player have vary size from 4.3 inch to 7 inch. They are space-saving and usually replace the original radio or CD player in your dash. When not use, the screen can be hidden in the body host or can be removed according the style, which can protect the LCD screen from wear. Most of in dash DVD player are intergrated with GPS Naivgation System, Bluetooth or Digital TV functions in the market today. As the screen is small, the rear passengers only can watch it hardly. While the video signal can be sent to back-seat screens. But the DVD can’t be used when the car is moving, though the navigation system can be used.

Portable DVD Player

It looks like a laptop computer, but it plays only movies, CDs and MP3 CDs. These players come with two headphone jacks and power adapters for use in cars, as well as at home and in hotels. Screen sizes range from 7 inches to 12 inches (provides comfortable viewing for two people). Many portable players sell for under $150, and they also can be used in a hotel, at home, and on a train or plane. Battery life is not an issue, as the player can be plugged into the car. While the device could fall to the floor during a sudden stop. So for safety, buy an unfolding travel case that straps to the front seats and secures the player.

Double Din DVD Player

It is the most popular DVD player in the market today. Like many original DVD players which come together with the new car, its display is the same size with DVD host. In a way, it beautifys interior environment of vehicle, and also with every nice visual effect. It is generally used for luxury vehicle.

Headrest DVD Player

Because watching TV while driving is not permitted by law, the headrest DVD player which be installed in the head of front seat seems safer. A headrest entertainment system handles more than just DVDs. It can also play audio CDs, MP3s burned onto discs and photos burned onto discs. In addition, there’s a connection for a game console or portable video player such as an iPod Video.

Of the 17 million vehicles sold in the United States annually, about 1.5 million come with rear-seat entertainment systems. And RSE systems are added to another 1.2 million vehicles each year, according to Phil Magney, president of Telematics Research Group, which provides intelligence on the automotive and mobile electronics industries.

Rear-seat entertainment systems can cost as little as $100 for a portable player held in your lap to $3,000 for a pimp-my-ride system with multiple screens. All the systems can provide DVD entertainment for two or more people. The differences involve who provides the player, how many screens are used and how the system is installed.

Which kind of entertainment system should you choose for your vehicle? That depends on your requirements, your budget and your kids.

Important Questions Answered- Water Feature Construction

Okay, now to the practicalities. Before installing a water feature you need to ask yourself several important questions first: What is your budget? How much can you spend on the entire project? You could spend $3,000 on a water feature and find out you still need an additional $1,000-1,500 for plants and amenities, such as a deck, gazebo, walkways, fish or landscape lighting in the pond, waterfall and lawn. Other possible extras are a biological filter, auto-fill for pond, skimmer, back-flushable bio-filter, and more. How big is a water feature? If you are building your own, then structurally size is not that big an issue! I would charge the same price for a 3-foot high waterfall as I would for a 5-foot; the same for a 3 by 5-foot pond as a 4 by 6. There is only a $200 difference in cost between the 1,000 and 2,000 square feet of concrete shell surface. Your main concern about size should be space, not cost.

How much of your yard can you sacrifice? Even if the space between your house and the property line fence is limited, a water feature can be incorporated. Small ponds 1 to 3 feet deep can facilitate a sump pump located within the pond. Even though a sump pump is inexpensive, it consumes much more energy than an above-ground pump.

A pond any deeper than 3 feet requires an exterior pump for better accessibility and maintenance, and at a higher cost. But they pay for themselves in a short period of time with the energy savings. Also, larger ponds require greater filtration, more cleaning and maintenance. The size of the waterfalls will determine the size of the pump needed. The higher the waterfalls, the bigger the pump needed to supply the water and the greater the cost for electricity. Height creates head pressure which requires more energy and is the major factor in operating cost. How much entertaining will you do? Will you need a deck? If so, how big? You might consider placing a pond next to an existing deck. Many people do just the opposite, they build a pond and then construct a deck beside it. In this case, you can take advantage of an existing deck and construct an open stairway (stair-bridge) to span the pond. This affords unique access to the opposite side.

Will you have adequate room for table and chairs? Do you want a spa? Or a fire pit or barbeque? Enough lawn for games? Where do you spend most of your outdoor leisure time? That is the area for your waterfall! The waterfall will bring you the most enjoyment, therefore it should be located closest to the area where you plan to spend most of your time out of doors.

Do you want to see or hear the waterfall from indoors? Consider adding an exterior patio or French doors to your house to access your water feature area. Do you wish to have fish and other aquatic creatures? Long term, a properly maintained nitrogen cycle costs less than maintaining a pond that uses chlorine and other chemicals.

Fish, plants and proper bacteria are needed for healthy pond and nitrogen cycle. Once properly established, a healthy fish pond is virtually maintenance free. Are you willing to remove or replace certain trees or bushes to enhance the waterfall and pond? Some trees have very aggressive root systems that can literally move concrete as they grow, causing cracking and upheaval.

Energy Efficient Double Glazed Windows

Energy Efficient Windows Can Save You Money!

When you fit Energy Efficient Windows to your home you can seriously save money on your energy bills. It is estimated by the Energy Saving Trust that households can save between 130-150 when windows are fitted with energy efficient technology.

By reducing heat loss when you fit energy efficient windows the environment also benefits, important for those concerned about the carbon footprint that our modern lives cause. Standard windows, which are usually single pane, have been shown in tests that they are very inefficient in keeping heat contained in the home.

Choosing the right window for your home is vital to making your home as energy efficient as possible. It is important to make an informed choice when buying energy efficient windows and you should always look for the Energy Saving Recommended logo. This means that the window and pane has been tested to ensure it is as energy efficient as possible.

Energy Efficient Windows Key Factors

When you decide to fit energy efficient windows to you home there are 3 components, which are vital to take in to consideration. The window frame material, the Energy Saving Window glass rating, and the way the window operates are key to ensuring your windows are as efficient as possible.

The Window Frame

The material you choose to fit your energy efficient windows or energy efficient double glazing with plays a key part in how energy efficient they are. Each material has pros and cons which may suit your household needs.

Metal or Aluminum Frames

Advantages of metal or aluminum frames are that they are very strong, not as heavy as other materials and do not require high maintenance. A disadvantage is that they are not so good at providing insulation.

Composite Frames

Composite window frames are made of composite wood products. These frames have better stability and thermal insulation properties than wood, and last longer as they are more durable.

Fiberglass Frames

Fiberglass window frames offer high insulation properties when the air cavities with the frame are filled with insulation. Fiberglass provides a strong structure for the window frame and result in high energy efficiency for windows.

Vinyl Frames

Vinyl windows are often made with polyvinyl chloride (PVC). Advantages of PVC is that in the frames do not require painting, have good energy efficiency with good insulation. Unfortunately in extreme weather conditions PVC can warp in heat and crack in the cold.

Similar to Fiberglass, vinyl frames can be filled with insulation to increase energy efficicency. These well insulating frames are often used with double glazing and high energy efficiency rating windows.

Wood Frames

Wood frames can perform well when it comes to energy efficient windows. A disadvantage is however that they also can be affected by changes in the weather. They also are heavy and take up more space reducing light in to the room, as well as needing the most work to maintain.
