Low-e window coatings

A thin layer of metal or metallic oxide, called low-E coating, can be applied to windows to significantly reduce heat loss. For homes in northern climates, it can help keep your indoor temperature more consistent during all seasons. It helps keep warmed air inside in winter and blocks excess heat and destructive UV rays from entering your space in summer. 


When it comes to energy efficiency, low-E glass coating is often a more effective treatment than traditional single and double glazing.


Here are just some of the advantages of having a low-E coating on your windows:


  • More even indoor temperatures in both summer and winter

  • Reduced sun damage on fabrics and furniture

  • Reduced energy bills

  • Higher property value


Low-E technology effectively limits the loss of heated or cooled air while blocking harmful UV rays, but it doesn’t reduce the beautiful natural light you adore. Therefore, with low-E coating, you can add more windows to your space, maximizing desirable light quality without compromising energy efficiency.
