Indow Is Discontinuing Shade Grade Inserts

Due to a disruption in the supply of solar-heat-reducing and UV-filtering acrylic, Indow will no longer be able to offer Shade Grade inserts. We are working on a replacement product, but because we have yet to identify a new supplier, we will not be able to accept Shade Grade orders.

What Are My Options Without Shade Grade?

Shade Grade filtered UV rays and blocked solar heat by 51%. If you are looking for a product that filters damaging UV rays, the Indow Museum Grade inserts reduce UV by 98%. Museum Grade has higher clarity than regular glass, without the green tint of Shade Grade.

With a near airtight seal and improved thermal insulation, all grades of our window inserts have shown to save 20% on air conditioning loads and will keep your home cooler and quieter all summer long.

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%
