These before and after pictures provide a great example of a typical Diamond Doors Quonset Retrofit.

Located in frigid Southern Manitoba, this farm owner needed a door that could fit his machinery and keep him warm while working on it. We supplied him a fully insulated 19×15 bi-fold door with 2 dual pane windows, keeping his building warm and full of natural light. To create a larger clear opening we once again used our Self-Supporting Header System. The header and frame extend past the buildings original roof line, providing support and structure for the bi-fold door and minimizing the loads transferred to the building.
