Devac 400 Series

The Window Man is proud to carry Devac 400 Series windows at its three Northern Virginia locations. The DeVAC 400 Series offers high performance single frame aluminum windows for moderate temperature zones. Its resistance to air and water penetration (as well as structural characteristics) make the 400 series similar to the 600 series. The 400 Series is a popular choice for the Southern United States.

You can improved the Devac 400 series thermal performance by glazing the vertical or horizontal sliding windows with 1/2" sealed insulating glass. Fixed models can accept 1-1/4" insulated glass or panels. The series can be coupled with interior and exterior trims used in the DeVAC "no tear-out" replacement systems.

Secondary Glazing Applications
The DeVAC 400 Series is also ideal as a "secondary" window when added to the interior or exterior of an existing single-glazed window system. This provides a cost-effective solution to energy savings at a fraction of the cost of replacing windows. In addition, this secondary glazing system is a proven method to reduce outside noise penetration.

Performance Standards (reports are available)
Air Infiltration................under .15 CFM/FT crack @ 25 MPH
Water Resistance................No leakage at 8.0 PSF (56 MPH)
Structural Load.................Resists 60 PSF (150 MPH)
