How to Insulate Windows to Keep Heat Out

 

Shade Grade Inserts:

  • Are made of ⅛” acrylic glazing with a soft green tint. They let in plenty of light while diffusing excess solar rays; like a pair of sunglasses for your windows.
  • Are edged in our patented silicone compression tubing, which creates a tight seal to insulate windows from heat.
  • Provide an air seal that also keeps hot drafts out.
  • Can be easily removed without damaging your window frames.
 

Shade Grade solar window inserts blend into the surrounding window frame, preserving the look of your original windows while also protecting what’s inside the room from damaging UV rays whether it’s furniture, artwork, photographs, books, wood floors or panelling.

 

Technical Data on How the Inserts Insulate Windows from Heat:

  • Solar Heat Gain Coefficient (SHGC) of .49, meaning it reduces solar heat gain by 51%
  • Maintains 57.5% visible light transmittance
  • R-value listing: 1.96
  • UV reduction: 90%
