In older homes, doors and windows are often one of the largest sources of heat loss in winter due to their low insulating ability and high air leakage rates. Windows are also generally the major source of unwanted heat gain in the summer. As a result, windows are typically net energy losers, and can be responsible for 25 to 50 percent of the energy used to heat and cool homes. However, better insulated doors and windows, combined with proper consideration of their placement and other details, can result in a net energy gain.
Radiant Barriers For Windows
Reflective technology in a transparent screen by controlling the flow of heat through windows.
The manufactures of window covering products design their products to block the sun’s rays from entering the home or office. The measure of effectiveness is reported as a percentage of reflectivity. Simply stated, if the rays of the sun are reflected out of the room; they do not have the opportunity to turn into heat energy inside of the room.
Solar Comfort products are manufactured using products developed by NASA for the construction of their space suits and for other applications in the space program. Having utilized this space technology, the Solar Comfort products have a very high degree of reflectivity.
38.6% Openness with a less than 10% reduction in visibility
71% Blocks Solar Heat/ Reflects inside temps back in 11% Solar Absorption 64% Blocks UV
NFRC is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings
Most Americans are already familiar with energy efficient lighting and energy efficient appliances but energy efficient doors? They may sound a bit Star Trek-like but when it comes to door insulation, energy efficient versions have been around for a while and there’s nothing science fiction-like about them at all.
So what makes energy efficient doors different from normal ones? Quite simply, it’s what they’re made of, the way they fit into and seal your doorframe, and the fact that they are nearly five times more insulating than normal wooden doors.
