Energy Efficiency OF YOUR WINDOWS AND DOORS
Energy efficient windows and doors will save you money.
Vinylbilt high performance offers a range of energy efficiency options from the minimum standards set by NRCAN to the most energy efficient as recognized by Energy Star Canada. Our windows and doors are designed to provide the optimum room side comfort, while keeping the elements where they belong - outside.
Vinylbilt offers a range of energy efficient glass and gas options from glass with single coating of LoE up to 3 coats. LoE is a coating applied to the surface of the glass that reduces heat loss while maintaining room side comfort. Choose the right LoE for your specific situation – more LoE when you need more protection from the heat and cold and less when you don’t.
Energy Rating System (ER)
A window’s ER rating is a measure of windows overall performance based on several factors:
- Solar Heat Gain – The amount of solar radiation that enters a building as heat.
- Heat flow through the frames and glass – This represents the heat flow through a window expressed in BTU’s.
- Energy Ratings(ER) – windows overall energy score set by Energy Star Canada.
- Visible Light Transittance (VT) – The amount of visible light transmitted through a pane of glass. The smaller the VT, the less visible light is transmitted through the product. The higher the VT, the greater the potential for day lighting to offset the need for electric lighting.
- U Value - describes how well a product prevents heat from escaping a home or building. U-value ratings generally fall between 0.2 and 1.2. The lower the U-value, the better a product is at keeping heat in. U-factor is particularly important during the winter heating season.
- R Value - Represents the resistance a material has to heat flow. It measures the effectiveness of insulation in stopping heat flow. The higher the R-value, the greater the better resistance.
