Information on Energy Efficiency
There is a Lot to Know About in Understanding Energy Efficiency
At MaritimeD&W, we understand that energy efficiency is more important than ever for the overall technical performance of your home residence or business location.
That’s why we are continuously looking for ways to make our windows and doors as thermally efficient as possible. From the materials we use and the glass packages we offer to our dedication as an ENERGY STAR® partner, we’ve got you covered when it comes to energy efficiency:
Important Terms and Definitions for Understanding Energy Efficiency for Your Home
U-Value: A U-value indicates the rate of heat transfer. The lower the U-value number, the slower it transfers heat from a warm area to a cold area.
Solar Heat Gain Coefficient (SHGC): The solar heat gain coefficient (SHGC) indicates the amount of solar gain through a pane of glass. It ranges from 0 to 100. The higher the number, the better the solar gain.
Energy Rating: The Energy Rating (ER) value is calculated using a formula that balances a product's U-value with its potential solar heat gain coefficient (SHGC) and its airtightness. The higher the number, the more energy efficient the product.
Premium Vinyl: Used in products, an excellent insulator. Thermal properties are far superior to aluminum, steel and stainless steel.
Spacer Systems: Unique spacer systems, made of highly thermally prohibitive materials, placed between the glass panes further reduce temperature transfer.
Glass Coatings: Products available with Low E glass, allows short-wave energy to pass through, but reflects long-wave infrared energy for greater thermal efficiency.
Gas Fill: The space inside an insulating glass unit—between the glass panes—may be filled with Argon gas, an odorless, non-toxic gas that is six times denser than air. This acts as an added barrier for a higher level of efficiency.
