5)
Save money knowing you'll use every piece.
6)
Use conventional framing methods to cut your bevels and compound miter profiles.
7)
For hangers and fasteners, use inexpensive and easy to find framing hardware.
8)
Use our deeper depths to achieve insulating requirements of new building codes.
9)
No bevel plates or stiffeners required because you can frame like dimensional lumber.
