ISOBRACE OSB
Rigid insulation for above grade exterior walls
LAMINATED TO A
7/16″ OSB
ISOBRACE OSB combines the insulation performance of an expanded polystyrene panel with the rigidity of a 7/16″ oriented strand board (OSB). In addition to providing high performance and continuous insulation, it helps to increase the structural rigidity of the building.
NEW AND RENOVATION
Residential. Commercial.
Advantages
ELIMINATES THERMAL LOSSES
Continuous insulation envelope. Installation of ISOBRACE OSB rigid insulation on above grade walls eliminates undesirable heat transfer zones called thermal bridges.
INSTALLATION: TWO STEPS IN ONE
Reduces work time and labor costs. When a rigid wood product such as OSB is desired for exterior walls, ISOBRACE OSB offers a solution that allows you to insulate thermal bridges of the frame in a single step.

Continuous insulation envelope
- Maximizes the insulation performance of the wall.
- Increases comfort and energy efficiency.
- Keeps the building warm in the winter and cool in the summer.
- Completely insulates floor joists — with 9 ft lengths.
Water vapor permeable
- Permeability-tested for the complete laminated “NVB” specified products.
- Perforated panel at regular intervals maximizes permeability of water vapor.
- Decreases the risk of mold.
Reduces work time and labor costs
- Can eliminate the need to add temporary bracing.
- Compatible with different types of structures.
- Depending on the chosen ISOBRACE OSB installation, can provide backing for cladding*.
- Resistant to breakage during handling.
* According to the cladding manufacturer’s recommendations.

Installation
ISOBRACE OSB product is quick and easy to install.
To ensure maximum insulating performance, make sure the installation follows the recommended practices.
Refer to the ISOBRACE OSB Installation Guide for complete installation instructions.
- Install the insulation on the wood studs, OSB to the outside.
- New construction: If installed in a seismically active area, validate bracing requirements that apply.
- Fasten panels with ordinary, twisted or corrugated nails.
- 6″ o/c at the edge of the panel;
- 12″ o/c along intermediate supports, max.
- Install the air barrier/weather barrier.
- Seal all joints.
- 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.
SUSTAINABLE BUILDING
LONG-TERM PERFORMANCE
- Stable insulation value year after year.
- Peace of mind: non-vapor barrier tested laminated product.
Other possible installation – OSB against the structure
