Energy Efficient Windows & Doors
UKKO is your source for one of the most energy efficient window and door products on the market today. Whether you are replacing windows and doors in an older home or building a new one, UKKO can provide not only the right windows and doors but can also install them professionally.
In Canada, energy efficient windows and doors are identified through labels with the Energy Star symbol. Energy Star is managed and monitored by the NRCan’s OEE (Natural Resources Canada’s Office of Energy Efficiency).
ENERGY STAR® qualified products help reduce greenhouse gas emissions by meeting strict energy efficiency guidelines that are endorsed by the Government of Canada.
What Makes Your Window Energy Efficient
Energy Rating (ER) for a window or a door is calculated using a formula that balances a product’s U-factor with its potential solar heat gain coefficient (SHGC) and its air tightness regardless of the manufacturing or assembly method and the materials used. The higher the ER number, which typically ranges from 0 to 50, the more energy efficient the product is.
Solar Heat Gain Coefficient (SHGC)
Premium Vinyl: Used in products, an excellent insulator. Thermal properties are far superior to aluminum, steel and stainless steel.
Low -E glass
The term “Low-E” Glass refers to a clear glass, with a microscopically thin coating of metal oxide that is non-visible to the human eye. “Low-E” Glass works by reflecting heat back to its source.The metal oxide coating keeps heat inside during cold climates and keeps heat outside during warmer climates.
“Low-E” stands for “low emissivity”, meaning that the glass in the window allows a small portion of energy to penetrate through. Conversely, a window that permits the heat from the sun or from your furnace to pass through would have a high emissivity. The more effectively the metallic layer insulates from this transfer of energy, the lower the emissivity.
There are two types of “Low-E” Glass:
Low-E: Allows as much solar heat to enter the home as clear glass. Commonly used in climates with cooler summers and colder than normal winters.
Low-E2: Allows for the least amount of solar heat to enter the home. Commonly used in climates with hot summers and mild winters.
Another benefit of “Low-E” Glass is its ability to allow visible light to pass through the glass, while blocking or reflecting ultra-violet and infrared lighting, which can be harmful to your skin, wood, and fabrics.
By replacing the air between the panes of a window with Argon gas, thermal performance is improved. Argon gas helps prevent convective heat loss (cold air moving through the window) as well as conductive heat loss (cold air being radiated from the window) to improve energy efficiency. Argon gas also acts as a sound proofing agent.
