Frequently Asked Questions
Since replacing my windows, I'm noticing more condensation than before at the bottom of the inside pane. How is this possible?
Condensation is appearing on your windows because they are better insulated! Water vapor occurs naturally in your home. It is trapped indoors because when your windows are closed, they offer a perfect seal. When the vapor comes into contact with a cold surface (e.g. mirrors, windows), it condenses into a liquid. The more your home is insulated, the more you must ensure proper and adequate ventilation.
What is Low-E Glass?
Low Emissive or “Low-E” glass has a special thin-film metallic or oxide coating on its interior surface, which allows the passage of short-wave solar energy (light) but prevents the passage of long-wave energy (heat) from the sun or heating systems through the glass. Low-E glass thus allows light to enter while also providing thermal insulation. This type of glass cuts the loss of heat during the winter and cuts the absorption of heat during the summer by reflecting the heat back to its source, thus providing year-round savings by lowering utility bills. Low-E glass also selectively filters the sun’s energy, blocking up to 84% of the sun’s ultraviolet rays in the summer, thereby reducing the degree of fading of upholstery, carpet and drapes. Low E also reduces heating costs reflecting room side heat back into the room resulting in a lower winter U-value.
What is argon gas and why is it used with Low-E glass?
Argon is a safe, odourless, colourless, non-toxic, non-flammable inert gas commonly used in place of air between the glass panes of an insulated Low-E glass unit. Argon’s heat conductivity is lower than that of air, and thus it is a better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself; that is why it is only used in conjunction with Low-E glass.
How can I tell if I need new windows?
- Difficult to open or close
- Air leaking through or around the window
- Excessive condensation or icing on the inside of the window panes
- Windows rattle in the wind
- Paint chipping or peeling
- House is always too cold in winter – or too hot in summer
Will replacing my old windows really cut down on my heating bills?
Yes! Windows are one of the most important aspects of regulating home temperatures. Most windows in older homes were designed when energy was cheap, and new energy-efficient materials were unknown. Today’s newer energy-efficient windows are designed with overall thermal efficiency in mind; keeping the heat in and the cold out. Typically, an older home can lose up to 50 percent of its energy heat through leaky, drafty windows and doors.
Are new windows a bad investment if I plan on selling my home?
No! In fact, not only will new windows make your home more energy efficient and visually appealing, but they will increase the overall value of your home.
What is the difference between "retrofit" and "full replacement"?
Retrofit means leaving the original (old) window frames in and installing the new vinyl frames within the existing. Full replacement means removing the existing (old) window frames.
What is a thermal breakage?
Like every other material, glass expands (and contracts) when it experiences temperature variations. This expansion tends to be greater at the center of the glass than at the sides, which applies pressure to the glass. In most cases, this pressure is absorbed by the glass and the design of the window. However, the glass may break; this is referred to as thermal breakage.
In general, thermal breakage is not covered by the warranty because it does not mean that your product is faulty. This phenomenon is quite unpredictable, so manufacturers cannot be held responsible.
The quality of window installation significantly impacts the performance and longevity of your vinyl windows. At A&G Windows and Doors, we employ trained and professional window installation specialists to provide exceptional tilt and turn window installations. We offer two types of installation services for vinyl windows:
Retrofitting your home with vinyl windows allows you to upgrade your windows for improved performance and energy efficiency without needing a full-frame replacement.
- It involves removing and replacing the window sash.
- The existing window frame and trim on your home’s interior and exterior remain intact.
- A faster and more cost-effective process compared to full-frame replacement.
- Recommended if the existing frame is in good condition and well-insulated.
- Allows you to upgrade window glazing for optimized performance.
Full Frame Replacement
For a more thorough option that offers greater efficiency and overall window performance, consider full frame replacement.
- Involves complete removal of the old window down to the house framing.
- After installation, the exterior is finished with caulking or aluminum flashing.
- Allows for upgrades to the interior trim and window jambs.
- Ensures optimal energy efficiency and thermal performance.
