Building Products of Canada has a wide selection of insulating sheathing products.

BP offers a wide selection of insulating wall panels made of wood fiber providing an environmental and economic option to meet local building codes.

BP's intermediate membranes are products installed on the outside of the wall cavity behind the exterior cladding. They protect against water infiltrations while allowing the moisture inside the wall cavity to escape outward, ensuring a dry and healthy wall for the life of the building.

Dupont Rigid Foam Insulation replaces non-insulating above-grade sheathing products like plywood, fiberboard and OSB, and eliminates the need for additional air barriers such as housewrap. It has clear film facings on both sides for added durability.

Styrofoam Boards are also designed for insulating interior basement walls, crawl spaces, and ceilings in both renovation and retrofit situations with precut insulation sheets and slotted edges that accommodate wood nailing strips that serve as a nailing base for drywall.
