ARMOR AND ENERGY EFFICIENCY
Save money with Armor’s range of high-performance energy-efficient windows. Designed for keeping the elements outside while ensuring optimal comfort inside, Armor’s energy-efficient window ratings range from National Resource Canada’s (NRCan) minimum standard to the highest Canadian Energy Star® efficiency rating.
Armor Windows and Doors also offers low-emissivity (LoE) energy-efficient glass known as Weather Tech and gas options known as Vapour Shield, which involves applying a special coating on the glass to minimizes heat loss and maintain room temperature comfort - the thicker the coating, the more efficient the glass. Armor’s options range from 1 to 3 layers of LoE coating to accommodate various requirements. The choice belongs to you.
THE ENERGY RATING (ER) SYSTEM: HOW IT WORKS
Several factors are taken into account when evaluating a window’s ER.
- Solar Heat Gain -The quantity of solar radiation conducted into a building as heat.
- Heat flow –The measurement of heat transfer through the frames and glass, in British Thermal Units (BTU’s).
- Energy Ratings (ER) – The quantity of daylight transmitted through glass. A higher VT may reduce electrical lighting requirements due to the greater amount of light entering a room. In contrast, a lower VT lets less daylight flow in.
- U-Value A value between 0.2 and 1.2 representing the overall heat flow of a product or, in other words, its capacity to keep heat from escaping outdoors. The lower the U-value, the better a product is at keeping heat in. Especially important during winter, a window with a lower U-value will perform better at keeping heat inside your home.
- 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 a material’s insulating value or resistance to heat flow. The higher the R-value, the better the product is at preventing heat flow.
