How do vinyl windows compare with windows made from other materials,
such as wood and aluminum? |
| Vinyl windows compare very favorably to those made of other building materials. Vinyl allows for smooth operation year round because of its self lubricating properties and the fact that it does not shrink, swell or bend during harsh weather conditions. The combination of aesthetic appeal, energy efficiency, and low maintenance provides equal or better performance and is often more economical. |
Why should I replace my existing windows? |
| Vinyl windows offers many styles to give your home a beautiful new look while improving energy efficiency. They can add value to your home while cutting down your heating and cooling bills. |
What are R-values and U-values? |
The R-value is the resistance a material has to the flow of heat,
(the higher the R-value, the greater the resistance).
The U-value is the amount of heat that is transferred through a material,
(the lower the U-value, the better insulating quality). |
How can I determine the energy efficiency and durability of a window? |
Two organizations, the American Architectural Manufacturing Association (AAMA) and the National Fenestration Rating Council (NFRC), test the performance and quality standards for windows.
The NFRC established standards for thermal performance.
U-factor: This is a measure of heat loss. The lower the U-factor the better.
SHGC (Solar Heat Gain Coefficient): Once again the lower the better.
VT (Visible Transmittance): The higher the visible transmittance, the more daylight is transmitted. A high VT is desirable to maximize the amount of daylight entering the home.
The AAMA established standards for structural integrity, air infiltration, water infiltration resistance and forced entry resistance.
Structural Integrity is the ability to withstand wind and other dynamic pressures. This is rated in design pressure (DP). The higher a product's rating design pressure, the greater the amount of wind or pressure the window will withstand.
Air Infiltration tests involve the equivalent of 25 mph wind. The lower the air infiltration rating the better.
Water Infiltration tests a window's ability to resist water leakage through the window frame, sashes, joints, weather-stripping, etc. No leakage is permitted under this test criteria.
Forced entry is tested by a certified lab technician using many different tools to simulate breaking into a home through the window. Next, windows and doors are subjected to hundreds of pounds of force to try to lift or push them open while in the locked position. |
What is ENERGY STAR and how does a window company qualify
for ENERGY STAR compliance? |
| ENERGY STAR was started by The United States Department of Energy. ENERGY STAR helps businesses and consumers become aware of what products save energy to save money while protecting the environment for future generations. When a product, such as a vinyl window, meets the requirements for ENERGY STAR that product then qualifies for the program. |
What is insulated glass and why use it in their windows and patio doors? |
| Insulated glass consists of two pieces of glass sealed to a spacer. This creates an insulated air space between the two pieces of glass, resulting in better thermal performance. Insulated glass also reduces condensation while keeping the heat in during the winter and the heat out during the summer. |
What is condensation and what causes it? |
Condensation is the result of excess humidity, or excess water vapor in the air coming into contact with a cooler surface such as a window causing visible droplets of water. To minimize this effect, vinyl windows are built with features to keep the surface of the glass warmer. When the humidity conditions are extremely high, use the following suggestions to help reduce the moisture in the air:
Open windows frequently to "air-out" your home.
Use a dehumidifier.
Use venting fans in the kitchen, bathroom and laundry room. |
What is LoE² glass and how does it work? |
| LoE² (low emissivity) glass provides year round comfort and energy savings. Two thin, transparent metallic coatings applied to the glass selectively filter solar radiation. During the summer, LoE² reduces heat gain, keeping your home cooler. LoE² glass helps keep you warmer in the winter by reflecting heat back into your home. |
Why buy Vinyl? |
Energy Efficiency - Vinyl is a great insulator, superior in its resistance to heat transfer. Dual weather stripping, standard on many of our windows, creates a tight seal, maintaining the efficiency of the window and effectively eliminating drafts.
Durability - All of our windows are thoroughly tested for structural and thermal performance, to ensure they hold up under extreme weather conditions.
Convenience - Tilt in sashes allow for safe and easy cleaning from inside the home. Windows open effortlessly, regardless of the temperature or humidity level. A vinyl frame will not rot, chip, crack or peel, and as a result, never needs painting. |
What are the advantages of fiberglass over wood and steel? |
| Unlike wood doors, fiberglass won't dent, crack, split or splinter. Unlike steel doors, fiberglass won't dent, rust or warp, either. Fiberglass also resists shrinking and swelling with temperature changes, allowing the finish to last three times longer than on a wood door. The solid polyurethane foam core offers five times greater insulation value than wood doors. |
