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.

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.

  1. 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.
  2. Fasten panels with common, twisted, or ring nails.
    • 6″ o/c at the edge of the panel
    • 12″ o/c along intermediate supports
  3. When installing ISOBRACE OSB, cover the product with an air/weather barrier membrane.
  4. 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.
  5. Seal surface changes with a sealant (openings, electrical outlets, etc.) and prepare the outline of the windows for airtightness and watertightness.
  6. Install 1″ x 3″ wood furrings vertically or diagonally (if recommended by the siding manufacturer).
  7. Install the exterior finish.
