DeVac 600 Series Dual Frame Thermo-Barrier

Here at The Window Man we carry many models of new and replacement windows, including DEVAC's high performance series.

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.

For New Construction or Renovation

Exclusive dual-pane/dual-barrier design* provides the highest STC (Sound Transmission Class) available in fully operating windows. STC's from 37 to 56 are obtainable in standard DeVAC window products glazed with common monolithic glass.

Devac's Thermo-Barrier™ frame and wide, trapped air space glazing system are key elements to the 600 Series' outstanding acoustic performance...performance not obtainable with laminated or sealed insulating glass.

Sound transmission loss tests consistenly show the DeVAC Acoustic Window system provides better STC ratings than the same thicknesses in other systems. There is no significant acoustic benefit from laminated glass in DeVAC Acoustic Windows, which means an economical installation that is not in conflict with life safety requirements. (Research tests also show a loss of acoustic performance when laminated glass is subjected to cool weather.)

With DeVAC, windows are not an acoustic "weak link" in exterior walls. In fact, selecting from many DeVAC product and glazing combinations to acoustically match the values of window and wall is the best way to assure that needed performance is provided without uneconomical over-specifying. Devac acoustic windows offer attractive, cost-effective sound control for new developments saturated by aircraft or freeway noise. The ease of maintenance, cleaning and operation, coupled with adaptable designs and accessories, also make DeVAC Acoustical Windows a top choice for retrofit at sites experiencing increasing disruption from outside noises intruding on the interior environment.
