Frequently Asked Questions About Windows

What makes WinDura Windows and Doors different from other companies?

WinDura offers a much wider menu of services than conventional window companies, including preventive maintenance, repairs and replacement for windows and doors (this includes a wide price and product range of replacement windows and doors). This enables us to approach each customer without a preconceived agenda.

This is a huge benefit to our customers because they receive recommendations tailored to their homes’ unique set of needs.

What types of window replacement materials can I choose from?

The predominant replacement window product is vinyl. WinDura offers a menu of vinyl windows in various price ranges, colors and styles. Fiberglass is another product category that WinDura offers, due to its strength and color flexibility. Wood windows can also be installed as replacement windows, however the best application is typically new construction.

When will I know it’s time for me to replace my windows?

You’ll know when to replace your windows when you notice your windows lack energy efficiency — this includes feeling cold and warm drafts in the winter and summer months; when the wood frame rots; and when drapes and furniture fade due to excessive amounts of condensation or solar damage.

What makes a window a “replacement” window?

While technically any window can be used to replace another, true replacement windows are custom-sized to fit the home’s opening, and are generally built with thinner frames (3 1/4″ is standard) to allow convenient installation, and the use of the existing interior and exterior trim. True replacement windows are far less invasive to install than windows designed for new construction.

Why shouldn’t I install the cheapest windows?

Today there are very inexpensive replacement windows on the market. While WinDura has access to these products too, we rarely feel they are a good value. Spending a little more to upgrade the weight and overall tightness of your window is money well spent in the long run.

What features and benefits should I look for in a window?

Among the features you should look for are: Insulated air chambers for reducing energy bills, double, or triple-paned insulated glass, interlock at sash meeting rails to combat air infiltration, glazing for added protection against the elements, foam filled master frame for added insulation efficiency, the ENERGY STAR® label, and a lifetime warranty on materials and installation. Some additional features designed to maximize value include: fusion-welded sash and main frame structure for strength and durability, dual ventilator locks for proper ventilation, tilt-in top and bottom sashes for easy window cleaning from inside your home, triple barrier weatherstripping for superior protection from air and water infiltration.

What sort of glass should I consider for my new windows?

A primary reason to invest in new windows is the energy efficiency realized in glass technology today. At a minimum, WinDura recommends double pane glass, with Low-Emissivity (Low-E) and Argon gas. This upgrade lends significant improvement over standard glass. WinDura has other upgrades as well, including multiple Low-E layers and triple pane glass. We will help you decide which product is right for you.

What is Low-E glass and why is it important?

Low-E glass is short for low-emissivity glass. It has a very thin coat of material on the glass to make it more efficient. The Low-E coating helps reflect heat away from the surface of the glass, keeping unwanted heat out in the summer and desired heat inside in the winter. Low-E glass is the most cost effective way to increase the energy efficiency of the windows.

Low-E coatings can also help reduce furniture and carpet fading by reducing the amount of ultraviolet (UV) radiation that enters the home. Harmful ultraviolet radiation can alter the chemical structure of dyes and other colorants in carpets and furniture causing fading.

How can I evaluate the performance of different windows?

The easiest way to compare energy performance of different windows and doors is to read the National Fenestration Rating Council (NFRC) label. It provides valuable energy efficiency information about the product including the u-value, solar heat gain and visible transmittance values. Also, check to see if the product is ENERGY STAR® qualified.

Can’t the argon gas leak out from my window glass?

Argon gas is a safe, inert and very dense gas injected between the panes of a muli-glass unit to increase efficiency. With today’s technology, no, at least not at an appreciable rate. There was a time in which glass sealants weren’t very effective, and gas leakage would occur. Sealants today, and the accompanying spacer components between the glass, have improved to reduce seal failure, and the resulting loss of Argon gas. Many manufacturers offer full warranty against this problem.

What does “U” Value mean?

‘U’ Value is an industry-wide accepted measurement of window efficiency. The lower the ‘U’ Value number, the more efficient the window. Windows today must come with NFRC (National Fenestration Rating Council) stickers stating the tested ‘U’ Value of the unit. Specifically, ‘U’ Value is the coefficient of heat transmission, or the time rate of heat flow through a material.

What is significant about ENERGY STAR labeled windows?

ENERGY STAR labeled windows and doors are twice as efficient as the average windows manufactured just 10 years ago. They help cut your heating and cooling costs and can make your home more comfortable without compromising cost, comfort, versatility, or style. These high-performing windows are available in every operator type, including double-hung, casement, sliding, picture, and patio slider. And, they are manufactured with most common frame materials, including aluminum, fiberglass, vinyl, and wood. Look for the ENERGY STAR logo on your new windows.
