SIPs Roofs

SIPs - Stronger. Straighter. Greener.

When compared to traditional roof systems, SIPs are the best alternative. SIPs are significantly stronger, with a far more predictable consistency. They are straighter, for better roof installation, upkeep, and they are considered one of the only green framing products on the market.

Structural Insulated Panels are composed of two sheets of oriented strand board structurally laminated and pressure-cured to a rigid core of foam insulation.

Installation of roof panels is determined by the structure of the roof. Your Project Manager will help walk you through requirements based on your floor plans. Questions ahead of time? Refer to the full Installation Guide, contact your dedicated Project Manager or your Contractor to answer your specific project questions.

Roof SIPs Products: Insul-Lam

Insul-Lam is used as a non-structural nail base in either a one-layer or two-layer roof system. For a two-layer system, the installation is the same as that for a one-layer system, except staggering the joints between the first and second layer.

It will be necessary to remove 1 1/2 inch of EPS from the edge of the Insul-Lam sheets that create the edge of the roof assembly. Removal of the EPS should take place with a heating element set to the proper depth.

Begin by snapping a chalk line 1 1/2 inches around the perimeter of the roof deck. The Insul-Lam should be flushed to the line. Begin laying the sheets together. Once an Insul-Lam sheet is in position, fasten the assembly to the deck with SIPs Screws, following the recommended fastening pattern.

Install lumber into the offset created around the perimeter of the the roof. Nominal 2X material should be inserted into the reveal. Once inserted, attach with 8d nails 6" o.c.

Once all Insul-Lam panels have been installed and fastened, roofing material may be installed following the roofing material manufacturer's instructions.
