Energy Efficient Windows
Selecting glass and tint
Retrofitting your home’s windows is more than finding designs that match your style preference. Well-thought out window selections, if done correctly, will also reduce your energy bill. Replacing older windows helps prevent energy leaks thanks to the new windows’ tight seals, weather stripping, and improved mechanisms. Homeowners interested in investing in their windows to improve their home’s energy efficiency have several options available to them.
One of the most cost effective ways for a homeowner to increase energy efficiency is to tint their windows. Tints come in a variety of colors and reduce heat/light transfer by absorbing incoming solar radiation. High-performance LoE is a specialized tint option available to homeowners that deflects heat by separating heat energy (long waves) and light energy (short waves) and allowing the short waves to pass while reflecting long waves. Unlike traditional windows, impact windows must be manufactured with the desired tint(s) inside the layers of glass. Aftermarket tints and films not only void the warranty of impact windows, they may also trap heat in the glass window pane and cause stress cracks.
For further enhanced energy performance homeowners may opt to install insulated laminate glass. Insulated glass contains two panes of glass to create a pocket of sealed air space that may or may not be filled with gas. Insulated glass may be used alone or in conjunction with tint and LoE. One drawback to insulated glass is it tends to be a pricier option. Regardless of a homeowner’s budget there are many options to decrease indoor energy usage and lower heating/cooling costs.
