Duralite

  • Metal holds heat causing glass to expand and contract
  • No metal touching glass gives you the true lowest U-Value

Duralite energy efficient windows offer a new level of thermal performance to windows by reducing conductivity up to 45%. This radical improvement in thermal properties is achieved by eliminating metal in the window spacer and replacing over 60% of the window spacer profile with air. This patented window design featuring a unique composite laminating technology without the use of metal results in superior thermal and durability performance for your windows.

Test results performed by a third party have proven that Duralite energy efficient windows offer the lowest U-value rating and best condensation resistance when compared to other window spacers.

Duralite is thermally the best energy-efficient insulating window glass system available on the market.

How We Create Energy Efficiency

We use a Duralite Spacer System with a glass spacer bar that, unlike commonly used metal spacers, allows only minimal energy transfer between pains of glass.

Our Ultimate 12 double-pane glass technology is engineered to reflect heat and cold.

Our glass is Energy Star rated.

Metal

 

Metal holds heat causing glass to overly expand and contract

  • Leads to moisture damage
  • Shortens life span of glass unit by breaking the seal prematurely

Duralite

 

Duralite virtually allows the glass to remain at a constant temperature around the perimeter

  • 50% better than Intercept
  • 90% better than aluminum
