Replacement windows are one of the most effective ways to increase the energy efficiency of your home. Energy efficiency, comfort and savings start here. Take a moment and read the information that follows to educate yourself on replacement windows. Then read below for our free glass package upgrade.
KNOW THE LIGHT THAT PASSES THROUGH YOUR WINDOWS
Who doesn’t like a home filled with beautiful sunlight. Depending on your climate, sunlight can help keep your home warmer during cold winter months. But in summer months, it can increase your cooling costs and cause uncomfortable solar heat gain. In any climate or season, sunlight can fade carpeting, drapes and furnishings.
There are three types of light that enter your home through your windows.
1) UV Light
Can fade carpets, furnishings and artwork.
2) Visible Light
Desired for the illumination that makes your home bright and inviting.
3) Near-infrared Light
Causes heat gain, can raise energy costs and make your home uncomfortable.
GLOSSRY OF WINDOW TERMS
Low E Glass: Glass with a transparent metallic oxide coating which allows short-wave energy to pass through but reflects long-wave infrared energy, improving the U-value.
Visible Transmittance: Visible Transmittance (VT) measures how much light comes through a product. The visible transmittance is an optical property that indicates the amount of visible light transmitted. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.
ENERGY STAR: ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices. Windows and doors that meet ENERGY STAR guidelines have been tested for optimum energy efficiency.
Argon Gas: This odorless, colorless, non-toxic gas is six times denser than air. When used to replace air between glass panes in insulating glass units, it helps reduce temperature transfer.
U-value: The U-value or U-factor is commonly described as the amount of heat transferred through a material. The lower the U-factor, the slower the rate of heat flow and the better the insulating value.
Solar Heat Gain Coefficient (SHGC): The SHGC refers to the amount of heat from the sun that windows and doors allow into the home. The lower the number, the greater the ability to reduce the amount of heat absorbed into the home.
GLASS PACKAGE COMPONENTS
There are four components to most insulating glass packages. The glass, the gas, the spacer and the panes.
1) THE GLASS: Upgraded glass packages feature Low E coatings for improved efficiency. Unlike clear glass, Low E coatings help lower heating and cooling costs.
2) THE GAS: Argon gas is an option to increase the insulation rating of your windows. The gas is sealed between the glass panes. It is a odorless, non-toxic gas that is much denser than air; therefore insulated better.
3) THE SPACER: Insulating glass units have at least two panes of glass, separated by a low-conductance spacer that helps minimize the migration and transfer of heat between the glass panes.
4) THE PANES:
Dual-pane. Dual-pane windows consist of two pieces of glass, with the option for Low E, Argon gas and a low-conductance spacer.
Triple-pane. For even greater thermal performance, triple-pane windows feature three panes of glass, creating two separate insulating air-spaces.
Laminated. Impact-resistant laminated glass consists of a durable inter-layer sealed between two layers of glass. This advanced glass package provides increased safety, sound control, UV protection and energy efficiency.
