GREEN-R-PANEL has developed a unique exterior wall panel system comprising of custom built sections to allow for simple assembly resulting in quick installation. This wall panel system is made up of 2×6 lumber studs on 16″ center with 7/16” Oriented Strand Board (OSB) cladding on the exterior side.

All window and door openings are prepared including engineered headers and framing around the openings. These two standard size panels – 4’ wide and 8’ wide are placed all around the perimeter of the floor system. There are even ‘modifiable’ panels for each of the four walls to allow for adjustments. The system is delivered with a full set of drawings and instructions for ease of installation. All panels are numbered relating to these instructions.

We deliver a computer engineered roof truss component system consisting of clear span trusses, with “energy efficient design”, 18″ overhangs, gable ends, hurricane ties and ‘H’ clips, 1/2” OSB sheathing, roof vents, and 15lb felt paper.
