Our standard traditional half round dormer is available in 24", 36" and 48" widths, in roof pitches of 3 to 18".
It features a half circle shape, making it's height, half of it's width.
A 6" flange all around is featured to secure this dormer to a roofing structure. All edges are hemmed up, with the except of the front edge, which is hemmed down with a kick.
All parts are soldered when possible. When not, they are riveted and sealed (for materials such as aluminum and steel).
The louver portion features a stainless steel bug screen on its back side.
Because of its size, frame supports are added as needed.
