Energy-Efficient Window Films

Low-emissivity insulating window films reduce heat and glare by blocking 99.9% of dangerous UV rays, varying amounts of visible light, and up to 97% of the sun's infrared heat. These films can reduce a window's solar energy transfer into a building by up to 80%, and often reduce temperatures by 8 to 15 degrees. Building owners benefit from a more comfortable climate and enjoy lower HVAC bills. Commercial clients can request an energy audit, and in some cases receive prescriptive utility rebates.

Layr works with clients to determine the best solution, with product recommendations ranging from very dark to nearly invisible.

3M all-season low-emissivity films are our most popular film for energy efficiency.

Did You Know?

New York Local Law 84 (NY LL84) was passed May 1, 2011, and requires any building over 50,000 square feet to submit an annual energy benchmark or face a $2,000 fine. This data is then publicly disclosed so prospective tenants can compare buildings' energy usage, allowing for more informed decisions about the costs of renting a building space.

I used Layr to install 3M window film in one room of my apartment. They were extremely professional and courteous throughout the whole experience. They returned calls and emails very fast, and even the guys who came for the actual install were really nice and professional. We are also extremely happy with the final product. The room is definitely cooler, and we haven’t lost any visibility out the window. I would recommend them to anyone without hesitation.
