New Construction Nailing Fin
Our Garden windows also offer a nailing fin for easy installation into new construction applications. The nailing fin is integral to the frame. It surrounds the full perimeter of the frame and helps make installations weathertight.
Insulated Seat Board
Highly recommended: Insulation board with an “R” value of 5 can be installed under the seat board to increase the “R” value to 6.22. This 1-inch thick lightweight rigid material is 100 percent waterproof.
