DeVAC 400 Series: Single Frame Non Thermo-Barrier

We're proud to carry the DeVAC 400 Series at all three The Window Man Northern Virginia locations. The DeVAC 400 are high performance single frame aluminum windows perfect for moderate temperature zones. The 400’s resistance to air and water penetration, as well as its structural characteristics, is similar to the 600 series, making it a popular choice for the temperature weather of Southern US.

You can achieve improved 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 400 series can be coupled with the interior and exterior trims used in the DeVAC "no tear-out" replacement systems.
