Weathershield Cellulose Fibre Blown-in Insulation

The short, cellular, wood fibres fill all voids and cavities. For a perfect fit at sufficient density, it will resist convective air leakage. Stopping air leakage through the building envelope ensures less energy is needed to meet heating and cooling requirements, and prevents condensation problems.

Whether you are installing new insulation or upgrading the insulation in a present home or building, we can advise you on the product best suited for your needs from our stock of fibreglass batt insulation, styrofoam and celfort products.
