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.

Dupont FROTH-PAK™ Foam Insulation is a two-component professional insulation kit. FROTH-PAK comes as a professional sealant for air sealing gaps and penetrations up to 4 inches wide or as a spray foam insulation to fill larger cavities providing both insulation and air sealing properties. The Class-A rating (flame spread of 25 or less) of FROTH-PAK™ Foam Insulation allows its use in a wide range of interior and exterior industrial, commercial, institutional and residential settings.

Dupont Styrofoam Brand Foundation Insulation products are installed against the exterior side of the foundation wall, suitable for use in pervious, semi-pervious & practically impervious soils and for sealing sill plates around door and window framing to reduce air infiltration.

Insulating heating and air conditioning ducts with duct insulation from Frost King improves efficiency as it reduces vibration and noise.

Frost King pipe insulation reduces costly heat loss from hot water pipes and prevents freezing and sweating of cold water pipes.

Protect expensive units and stop wasteful leaks with winterized poly/fabric covers, compressible foam strips and outlet sealers from Frost King.

Knauf's cost-effective thermal and acoustical batts and blankets are made from highly resilient, inorganic glass fibers bonded by a thermosetting resin.

The products are available unfaced or with kraft, foil, or flame-rated FSK-25 (Foil-Scrim-Kraft) foil facings.

Knauf duct insulation is designed for commercial and residential air handling installations for cooling, heating, or dual-temperature service where good temperature control, noise absorption, and abuse resistance are required.

Available as board, liner, wrap and rigid plenum liner.

Nu-Wool is a spray-in-place, energy-saving cellulose insulation. It eliminates the voids and air pockets common with other insulation materials. In fact, you may save as much as 40% on your heating and cooling bills by choosing Nu-Wool Insulation when you build.

Nu-Wool has a high R-value, offering superior thermal and air-filtration properties, defending against mold growth and even dramatically reducing noise transmission through floors and walls.
