Enviroseal™ CW Wall Wrap

Benefits of Wrapping

Benefits once your building is complete

Reduces draughts: Wall Wrap reduces draughts through the wall frame and around wall insulation. Reducing air infiltration makes a building more comfortable and helps insulation work more efficiently.

Reduces moisture entry: Wall Wrap can reduce moisture entry through the wall helping prevent structural damage to the frame and allowing the wall insulation to perform at the specified R-Value rating.

Increases energy efficiency: Wall Wrap helps a building improve its energy efficiency by protecting the wall insulation from draughts and moisture entry.

Benefits before the external wall is applied

Protects the building structure from the weather: Wall Wrap protects a frame and floor from water damage before brick walls or cladding is installed.

Improves on-site work flow efficiency: Wall Wrap can improve on-site work flow by allowing internal trades to commence work before the brick walls or cladding is installed.

A typical ventilated wall assembly will experience a loss in the thermal performance of the wall insulation due to air-flow through the assembly, regardless of the type of insulation installed. (Building Science Corporation, 2013) This loss is a result of the infiltration of air changing the temperature of the air trapped around the insulation, which in turn changes the effectiveness of the insulation to achieve its designed R-Value.

The installation of wall wrap (either permeable or non-permeable) can help reduce air-flow around insulation and through the building cavity, allowing the insulation to work more efficiently. Consideration of condensation management then becomes important in the selection process based upon location and building design as wall wrap is an important element in the effective management of condensation in a building.
