Heat, Light and Sound
New windows can lower heating bills, prevent summer over-heating, reduce glare, block UV, and shut out noise to improve your comfort year ‘round.

Here are some basic tips:

• Always select LoE glass for energy savings and UV blockage. LoE helps keep a room warmer in winter; cooler in summer. It really works!
• By using LoE glass, you can avoid tinted glass unless your goal is to permanently darken your room and view.
• Request different glass pane thicknesses or “sound control glazing” to reduce noise.
