Solar Window Films

Solar window films help block summer heat gain.

The effectiveness of cutting energy costs by using  reflective films depends on many factors:

• Size of window glazing area
• Window orientation
• Climate
• Building orientation

Silver, mirror-like films typically are more effective than the colored, more transparent ones. East, south and west-facing windows, because of their greater potential for heat gain, can benefit more from these films.

North-facing windows won’t really benefit from reducing solar heat gain. However solar film reduces 99.9% of harmful UV rays from light which in turn reduces fading of furniture and furnishings. They also give you daytime privacy.

Solar film also acts like a low-emissivity film which will reduce about 15% of the radiant heat from escaping through the windows in the winter time

These films have some overall disadvantages:

• Some loss of interior light
  
• Extra care required for cleaning
• Reflections.

These reflective films are available to apply yourself over existing windows. The installation can be very tricky. It is recommended an expert install the film.

You can choose window treatments or coverings not only for decoration but also for saving energy. Some carefully selected window treatments can reduce heat loss in the winter and heat gain in the summer. They include the following:

• Awnings

• Blinds

• Draperies

• Solar Films

• Solar Screens

• Overhangs

• Shades

• Shutters

• Storm Panels

Window treatments, however, aren’t effective at reducing air leakage or infiltration. You need to caulk and weatherstrip around windows to reduce air leakage.
