Frequently Asked Questions

How do vinyl windows compare with windows made from other materials, such as wood and aluminum?

Vinyl is today’s most popular choice for window material. The maintenance free and energy efficient benefits of vinyl are second to none. Since the mid ‘90’s, however, the popularity of vinyl has sky-rocketed due to the cosmetic and design enhancements that have been added to vinyl products to distance them from the other composite choices.

How do Ellison windows compare with other vinyl windows?

Ellison offers comprehensive product lines in both new construction and replacement markets. Products in the fenestration industry still go to market through distribution, to a large degree, and that is a “push” industry. In other words, there are not many brands that have any consumer recognition, including Ellison. However, Ellison offers just about every style available and has good-better-best price points that allow any home to be upgraded or built with Ellison products.

What does it mean that Ellison windows and doors pass AAMA and NFRC tests?

AAMA is an industry organization that independently establishes structural standards for manufacturers to meet and exceed. Most brands of windows will be tested and labeled with an AAMA sticker. NRFC is the trade organization related to the energy efficiency of windows and doors. If a brand does not proudly state its membership to each of these organizations, then a consumer should question the absence. Please go to each organizations web site for more information.

How do I know when I need to replace my existing windows?

That’s up to you as a consumer. When you are tired of painting, or tired of dealing with that fog between your panes, or those incredibly high power bills in the summer and winter, or the air you feel when you walk by a window, you may need to consider replacing them.

Please recognize, that a lot of the cost of heating and cooling your home may be off-set by the incredible energy efficiency of new, Energy Star compliant vinyl windows.

What does R-value and U-value mean?

R-Value is a term that measures the insulation properties of a material. For example, fiberglass insulation is measured by its “R-Value.”

The energy efficiency of windows is measured by “U-values.” Because windows are not insulators by design, they cannot be measured in “R-Values.” However, windows obviously have insulating properties, so there needs to be a measurement that allows comparison of styles and window packages.

There is a relationship between R-values and U-values. Whereas the higher the R-value, the greater its insulating ability, the lower a U-value, the better that product’s insulating efficiency is. To find a U-value, divide the number ‘1’ by the R-value. For example, an R-value of “4” is equal to a U-value of .25.

What is Energy Star? What qualifies your products?

Energy Star is a national campaign sponsored by the E.P.A. and the Department of Energy to promote energy efficiency products. The endorsing logo may be found on computers, appliances, power tools, etc. Any product that uses or affects energy may have an Energy Star rating.

All Ellison products with Low-E glass and Argon insulating gas are Energy Star compliant anywhere in the country. Although the organization has divided the country into zones with separate criteria, Low-E and Argon will render every Ellison product compliant in all regions.

Can I order a window or door to fit any opening?

Yes, however, in some cases you might have to order multiple windows to fill one opening. Some openings are just too big and may require multiple windows joined together in order to fill the opening. There are standard window sizes that accommodate the majority of applications, but many openings will require custom sizing. The same applies to doors. Some openings will require a standard door size with custom sized transoms or side-lites to make the opening appear correct.

The best suggestion is to consult a replacement window dealer or professional contractor. With some imagination and consultation, even the most complex and large opening may be fitted with a replacement window…it’s just that some configurations may require more than one window, door or combination.

What is insulated glass? Why does Ellison use it?

Insulated glass is two panes of glass separated by an insulating spacer. This provides optimum energy efficiency and allows options to be added to a window’s glass package.

What is condensation? What causes it? Is it covered under warranty?

Condensation is a result of too much humidity in a room and has nothing to do with the performance of a window. No manufacturer’s warranty covers condensation on the outside of the glass. Condensation on the INSIDE of an insulated glass panel denotes seal failure and, depending on the coverage period, would be covered under a manufacturer’s warranty. Ellison offers a range of seal failure warranties, ranging from a pro-rated 25 year period to a pro-rated lifetime coverage period.

What is Low-E glass?

Low-E glass stands for low emissivity glass. Made during the manufacturing process of the raw glass, low-e is not a film, rather it is a component in the surface of the glass. The actual ingredients in low-e glass vary from type-to-type, but the basic premise is the same: low-e glass reflects heat away. During summer, it reflects heat away from the house and during winter months it reflects the heat generated by a furnace back into a home.

Ellison uses a low-solar gain low-e with a double coat of silver (also referred to as a “soft-coat” low-e).

What is Low-E glass with Argon Gas? How does it work?

Added inside an insulated panel with low-e glass, Argon gas is an invisible, insulating blanket that replaces most of the air during the manufacturing process. With low-e reflecting heat away, Argon gas buffers thermal transfer to enhance the performance of the whole glass panel.

What kind of maintenance will my Ellison windows require?

The good news is they will never require painting. When you see dirt or unwanted film on the glass, just use a gentle glass cleaner and wipe clean. With grids between the panes, it’s that much easier. When you see outside sills and vinyl collecting dirt or getting dingy, just wipe clean with a gentle cleaner and soft rag, or just use water and a rag.

I plan to have Ellison windows installed in my home. How can I be sure the window installer is qualified to install them?

Ask for references. We do not know all the dealers in the country who sell our products and cannot offer recommendations for that reason. Just like any investment in your home, this is a significant project and we urge you to exercise due diligence in this process. Rest assured, Ellison is a great brand of products and is one of the premium brands in the country. However, installation is a critical component in the overall process and you should pursue every avenue to ensure the dealer presenting to you the Ellison product line is the one you feel comfortable affecting the value and appearance of your home.
