What are the advantages of vinyl windows over windows made with wood, metal or a combination of materials?

Vinyl is the ideal window construction material because vinyl:
  • Doesn’t deteriorate or rot.
  • Can be extruded and shaped into brilliant window designs.
  • Doesn’t damage or corrode when scratched.
  • Can be fusion welded to eliminate air and moisture leaks at the joints.
  • Offers excellent insulating properties – especially when used in multiple-cavity frame designs.

What is ENERGY STAR ®—and what does it have to do with windows and doors?

ENERGY STAR is a U.S. government program—administered by the Department of Energy and the Environmental Protection Agency with the cooperation of manufacturers—that’s designed to reduce the consumption of fossil fuels through the education of consumers. The program covers many different types of products. Windows and doors can only carry the ENERGY STAR label if they are tested by an independent laboratory through the NFRC program and meet specific, predetermined U-value ratings. By selecting ENERGY STAR products, you will reduce your energy costs and help make the environment cleaner.

What is the NFRC and what should I know about it?

NFRC stands for the National Fenestration Rating Council. It’s a program established by the U.S. Department of Energy to help consumers compare window products and options. Window manufacturers participating in the program are required to label every window to its specific thermal performance level. Customers are then ensured that the products they select meet the requirements for their application. Participation in the NFRC program is voluntary. Not all manufacturers participate because it requires outside third party inspection and extensive product testing. Nescor IS a participant in the NFRC program.

What are the advantages of custom replacement windows over pre-made, standard-size windows stocked at home centers and lumber yards?

Because custom windows are made to fit perfectly, they provide the best energy efficiency (which saves energy costs) and install much more easily and with very little mess. Also, because of the myriad of options available that affect appearance and efficiency, custom windows allow consumers to design exactly the windows they need or want.

Standard windows typically cost less in the beginning, but other expenses and factors—like additional labor and the disruption to the home—far outweigh the original savings. For example, installing stock windows requires that you add brick or siding to the exterior, and drywall or other materials to the interior. In addition, custom-made windows allow you to choose the best solution to the problems you want to solve by replacing windows.

What is a replacement window?

A true replacement window is a window that’s custom built to fit within the opening of an existing window. It’s built to fit precisely and can be installed without disturbing the interior and exterior areas around the window.

Do replacement windows really pay for themselves or is that just a sales line?

It’s true if you select high-quality, energy-efficient windows. Expertly engineered and well-built windows lower home energy consumption. With vinyl-framed windows, maintenance is also virtually eliminated. No need to scrape and paint windows.

These energy and maintenance savings will allow you to recoup your window investment over time.

How are replacement windows any different from older windows in terms of cleaning?

Many high-quality windows are actually engineered to make cleaning easier. For example, double-hung windows with the latest internal constant force balance system allow a home owner to easily maneuver the sashes up and down. They tilt in—and lock securely in place—for safe, easy cleaning. Quite a difference from old wood windows that stick and are difficult to move up and down.

Are there differences in the vinyl used by window manufacturers?

Absolutely. Vinyls are like any other man-made compounds. There are numerous components in vinyl compounds and there are many vinyl manufacturers that produce numerous types and grades for window manufacturing. Lesser-quality vinyls typically have problems with brittleness or impact resistance, color consistency, and expansion and contraction. The best vinyls are proprietary compounds formulated specifically for manufacturing high-quality windows.

What makes one window stronger than another and why is window strength important?

The profile design and methods of assembly determine the strength of a window. Just as beams or roof trusses are designed for specific mechanical loads, so are window shapes.

The strength of the sash and frame dictate how the window will maintain its shape under high winds. A weak window can flex and reduce the effectiveness of the weatherstripping, resulting in air and water infiltration and, subsequently, higher energy costs. A weak window design also requires near-perfect window installation to ensure an effective seal.

You’ll have windows with long-term strength and squareness if you select windows with:
  • All fusion-welded joints
  • Glass sealed to the sash frame

Do woodgrain vinyls really simulate the look of wood and how well can they match different wood types?

Advances in vinyl technology allow quality woodgrain vinyl laminates to come very close to the look of real wood. It’s very attractive and it often matches the color of the wood trim in homes. An added benefit is that woodgrain vinyl laminates never need to be stained or sealed.

What makes a window or door energy efficient?

Numerous factors, including how the frame and sashes are engineered and built, the type of glass used (single-, double- or triple-pane), the weatherstripping, the type of low-emissivity coating on the glass and the presence of argon or krypton gas.

What is an R-value and how important is it in selecting windows?

Although the U-value is actually the important number in evaluating windows and doors today, most people are more familiar with the related concept of R-value (or R-factor). The R-factor of a window is the measure of its resistance to the transfer of heat flow. The higher its R-value, the greater its insulating ability.

What is a U-value?

U-value (or U-factor) is the measure of the window’s ability to conduct heat—in other words, the amount of heat transmitted through the window. The lower a window’s U-value, the better the window is at insulating your home.

What is Low-E and, how important is it to have it on your windows or doors?

Low-E stands for low emissivity and is a fairly new advancement in glass technology. Basically, it’s a microscopic, metallic coating—applied to a surface of glass—that reflects and re-radiates heat energy either into or out of a home depending on climate conditions. Using Low- E is an excellent way to increase the energy efficiency of a window. In fact, it’s so effective that every Nescor window with Low-E is ENERGY STAR®-compliant in every region of the U.S.

Can windows keep out UV radiation that fades carpeting, furniture, draperies and upholstery?

Using a low-emissivity glass in your new windows or doors will filter more than 50 percent of the damaging UV light. The absolute most effective glass for this purpose, however, is Heatshield 19, a new technological breakthrough in insulating glass, incorporating high performance soft coat Low E with a special coated glass that locks over 99% of harmfull ultra-violet radiation.

Is having a BPI Certified Professional important?

A Building Envelope Specialist is a certification given after taking a training course on how to define a homes heating and cooling envelope, diagnose any inefficiencies and being able to develop a correction plan. A traditional home improvement company sells you what they have, which is an incomplete approach to making a home energy efficient.

How much does an Energy Audit Cost?

For a limited time, NESCOR is doing audits for free in order to meet new potential clients. We understand that some homes will not need any work, some will need only a little bit of tweaking(such as air sealing or additional insulation) and some will need a more substantial correction plan. Since we can’t tell without performing an audit, we are willing to help out everyone.

If I have a lot of insulation, why do I need Attic Shield?

Insulation slows down the conduction and convection of heat. In the wintertime your heat escapes through the insulation. In the summertime the heat penetrates your roof and attic, goes through the insulation and into your home.

Why is this? Because insulation does not stop radiant heat loss or radiant heat gain. 50% of your heat loss in the winter is through radiation, and 93% of your heat gain during the summer is radiation.

Only a combination of Air Sealing, Insulation and a Radiant Barrier will contain the heat in your home throughout the winter, and block solar heat gain through your roof in the summer.

What is wrong with traditional Asphalt Shingles?

Every major brand of Asphalt shingle is now under class action lawsuit for breach of warranty. Asphalt shingles used to contain a much larger amount of petroleum which gave them longevity. As oil prices have risen, manufacturers stripped out more and more petroleum and added fillers in it’s place. When you check the MSDS(material safety data sheet) for an asphalt shingle, you will surprised at how little petroleum is actually left. The manufacturer’s changed there 20, 30, and 40 year warranties to now read (in fine print) that they prorate the warranty claim down to 10% of the material cost of the job after only a 5 year period! Guess they know something they aren’t telling us.
