Insulation
Weathershield and WallBAR are loose-fill cellulose fibre insulation products manufactured from selected recycled paper stock. So why is the Weathershield / WallBAR system much more effective than common glass fibre insulation?
- Density – Typically 2-3 times more dense than glass fibre products, resulting in superior air infiltration.
- Dead Air – The hollow fibre structure traps air within the fibres themselves. The dead air produces a higher thermal resistance and guarantees a stable performance through a wide range of temperatures.
- Perfect Fit – Because this product is a loose-fill product, they can completely fill any area. This is very important in achieving the best thermal and acoustical performance.
