EXTERIOR WALLS

Weathershield's superior thermal properties compared to other insulating materials makes it a natural choice for insulating exterior walls. Weathershield contains millions of tiny air spaces around and within its hollow fibres which progressively reduces the flow of heat.

One of the most common problems in exterior walls is air leakage around electrical boxes. Weathershield flows around and conforms to electrical boxes, plumbing, wires and nails and seal them against air and moisture infiltration(a common problem associated with batt type insulation).

Weathershield is installed utilizing an innovative installation method called the Enviro-Shield Wall Insulation System. This method utilizes techniques to ensure that cavities are uniformly and consistently filled to a dry blown density of 3.00 lbs/ft3 (48 kg/m3) to ensure no settlement occurs . Under the Enviro-Shield System insulation can easily and quickly be installed directly behind either polyethylene vapour barrier or mesh and can achieve up to R-23 on 2x6 frame walls.

Weathershield installed in walls is up to 3 times more dense than batt type insulation. Studies have shown that retrofitted walls insulated with cellulose insulation showed a 24% reduction in air infiltration. Additionally, the higher density provides superior control of lower frequency sounds such as those associated with air traffic and road noises.

Weathershield is suitable for both wood and steel frame construction and eliminates the need for an exterior air barrier system.
