ISOBRACE OSB and ISOBRACE AIR+
Rigid insulation for above grade exterior walls
LAMINATED TO A 7/16″ OSB
ISOBRACE panels combine the insulating performance of expanded polystyrene panels and the rigidity of 7/16″ oriented strand board (OSB). They ensure continuous insulation while helping to increase the structural rigidity of the building. The integrated membrane of ISOBRACE AIR+ provides a continuous and resistant air and weather barrier.
NEW AND RENOVATION
Residential. Commercial.
Advantages
An expanded polystyrene panel laminated to an OSB panel perforated at regular intervals.
The combination of ISOBRACE OSB and a membrane made of strong non-woven engineered fabrics laminated onto the OSB surface, which can be used as a weather and an air barrier.

Installation
ISOBRACE OSB and ISOBRACE AIR+ products are quick and easy to install.
To ensure maximum insulating performance, make sure the installation process follows recommended practices.
Refer to the ISOBRACE AIR+ Installation Guide for complete installation instructions.
- Install panels with OSB and/or printed membrane facing outward, allowing the foam to be in direct contact with the framing. Ensure that all edges of the panel are well supported.
- New construction: If installed in a seismically active area, validate bracing requirements that apply.
- Fasten panels with common, twisted, or ring nails.
- 6″ o/c at the edge of the panel
- 12″ o/c along intermediate supports
- When installing ISOBRACE OSB, cover the product with an air/weather barrier membrane.
- When using ISOBRACE AIR+, seal all joints with sealing tape or a self-adhesive sealing membrane. Framing nails used for fixing the panel must be covered.
- Seal surface changes with a sealant (openings, electrical outlets, etc.) and prepare the outline of the windows for airtightness and watertightness.
- Install 1″ x 3″ wood furrings vertically or diagonally (if recommended by the siding manufacturer).
- Install the exterior finish.
