Dual Seal-Silicone/PIB

Two moisture-barrier side beads of PIB (Polyisobutylene), which is UV resistant, minimizes moisture permeation and provides an outstanding argon barrier.

Warm Edge IG Units

Warm Edge IG units have the significant advantage of not conducting as much perimeter cold temperature through the unit as a metal spacer, increasing the units efficiency.

Argon Gas Filled

We use argon gas between the sealed window panes, increasing the efficiency of the insulated glass. It also helps prevent frosting and promotes sound proofing.
