Invest in double glazing While traditional windows contain just a single sheet of glass, double glazed windows are comprised of two sheets of glass separated by an insulating air gap. This air gap creates an additional layer of insulation, preventing heat loss while still allowing sunlight into the home.
How could you reduce heat loss through windows?
use closely woven, close fitting internal window coverings such as curtains or blinds. ensure a snug fit on both sides of the window and at the top of the curtain to stop warm air from moving down behind the curtain and cooling.

Does foil on windows work?
Yes. Emergency management agencies specifically recommend using “aluminum foil-covered cardboard” between windows and drapes to reflect heat back outside.
How can I proof my window for energy?
You can apply foam tape as a great weather-proofing alternative for doors and windows that are a little old and warped. It’s also worth thinking about any curtains or drapes you have. When drawn during cold weather, most conventional drapes can effectively reduce the loss of heat from a warm room by up to 10%.

Why is cold air coming through my windows?
Why Is Cold Air Coming Through My Windows? Drafts occur when there are gaps in the construction of your window, allowing cold air to come through. This opening is left unsealed to the outside, allowing your home’s warm air to leak out and cold air to enter from outside.
Will putting plastic over windows help?
Plastic window film covers can reduce drafts and make your home feel warmer during the winter. They are also a relatively inexpensive way to reduce condensation buildup and lower energy bills. Window wraps can also seal air leaks around the window, when those leaks extend over woodwork.
Do thermal curtains really work?
Yes! Thermal curtains work effectively during both winter and summer. Medium- to light-colored curtains with a white, thermally reflective backing can reduce heat gain during the summer by as much as 33% by reflecting solar radiation. The orientation of the window also affects energy efficiency.
Can you over insulate a house?
It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That’s when mold starts to grow.
What is the biggest source of heat loss in a house?
Roughly 35% of all heat loss in a home occurs through the walls. This loss generally occurs through conduction or physical contact since a home’s walls are in physical contact with the colder temperatures outside. The heat energy inside your house is primarily transferred by conduction through the walls.
How much heat is lost through a window?
Around 18% of the total heat within a house is lost through the windows. This heat loss through windows is caused by radiation through glazing, convection and conducted through the window frame.
Do curtains reduce heat loss?
Closing curtains at night can reduce heat loss by up to 17 percent. According to the U.S. Department of Energy, using curtains with thermal lining can reduce heat loss by up to 25 percent. Using curtains with white plastic backings can reduce heat gain by up to 33 percent.
Do insulated windows make a difference?
You can also further boost insulating value by adding low emissivity or low-E coatings to glass, which help reflect rather than absorb the sun’s rays. Fortunately, no matter what IGU you select, you’ll reap energy savings – depending on the type of panes you replace, as much as 50%!
Does thicker glass reduce heat loss?
Did you know: the thickness of glass only relates to the strength or resilience of a window and has virtually no impact on performance in energy efficiency. Thicker glass is typically used to protect against high wind loadings; it’s most commonly used in the upper levels of high-rise apartments or office buildings.
Is solar reflective glass worth it?
For south-facing rooms, solar control glass can be crucial to making spaces more comfortable during the summer months when UV rays are at their strongest. It obviously works to help keep rooms cool, but adding them to your skylight instead of normal glass also helps to improve your home’s thermal efficiency.
What is the best thickness for window glass?
The vast majority of residential windows use Single Strength glass which is 3/32” thick. For larger windows, Double Strength, or 1/8” thick glass may be required. For extremely large residential window it may be necessary to use 5/32” or 3/16” thick glass to assure adequate wind-load resistance.
