DeVac 600 Series Windows: Dual Frame Thermo-Barrier

The DEVAC 600 Series high performance dual frame Thermo-Barrier aluminum windows have a wide airspace between interior and exterior glass panes to conserve energy and reduce outside noise penetration. The unique, non-structural DEVAC Thermo-Barrier provides the key to effective performance by meeting essential design criteria:

* Insulates interior frame and sash from costly thermal transfer and improves condensation resistance.
* Effectively seals against air and water leakage through barrier into wall structures.
* Allows freedom of expansion and contraction while keeping structural integrity between interlocking parts.
* Interlocks aluminum frame members so that forces generated by thermal movement and structural load will utilize the barrier material for it's greater compressive strength. A design principle proven by 30 years of service with no failure.
* Custom sized to 1/32 of an inch. Available as double-hung, horizontal slider, removable panel and fixed panel. Historical designs and special shapes are offered.
