Choose to save energy. Choose to increase comfort and productivity. Choose ECOGLASS/HM – Dual Plus, Quad or Superquad.

We manufacture ECOGLASS/HM with one, two or three Heat Mirror® films to achieve insulating values up to R-20. It’s your choice, of course.  No Other Glass Does That!

1” ECOGLASS/HM Dual Plus – R9

ECOGLASS/HM Dual Plus is made with a single layer of Heat Mirror® film laid between two glass lites. The cavities can be filled with argon or krypton gas. Choose LowE glass and fill the cavities with krypton to achieve the highest insulating values for Dual Plus. R9.

Our product line of ECOGLASS / HM88, ECOGLASS / HMTC88 and ECOGLASS / HMSC75 offer high transmittance, low reflectance glass. These films allow for high light transmittance without sacrificing performance. Common applications include residential, retail space, schools and commercial buildings where architects are looking for a clear appearance.
With units as small as 1¼” overall depth, COG values of R-9.4 can be achieved with a SHGC of .29 and visible light transmission of 54%.



1.5” ECOGLASS/HM Quad – R-15

ECOGLASS/HM Quad is made with two layers of Heat Mirror® film laid between two glass lites. Filled with krypton, you can achieve insulating values up to R-15. Because film is essentially weightless, a second Heat Mirror film can be added for higher insulating performance. (U-value 0.068).




2” ECOGLASS/HM Super Quad – R-20

ECOGLASS/HM Super Quad is made with three layers of Heat Mirror® film laid between two glass lites creating four air spaces. Filled with krypton and xenon gas, you can achieve insulating values up to R-20. (U-value 0.05).

It’s the most energy-efficient glazing product in the world.
