Enviroseal™ CW Wall Wrap

The Bradford range of Enviroseal wall wrap products provides a number of benefits to make a structure more comfortable and reduce the risk of condensation which can lead to mould.

Wall wraps are pliable building membranes that are applied to the outside of the building frame and offer benefits and protection during construction, as well as when the structure is complete.

Features and Benefits

Enviroseal Wall Wrap products are highly vapour permeable products that allow water vapour to pass through them, whilst preventing the entry of liquid water and dust from outside. When used in colder climates where there is more moisture inside the structure than outside, they allow moisture in the air to pass through the membrane before condensing to water (condensation) safely on the outside of the building frame where it does not damage the building.

These products are recommended for use in colder climates where the risk of condensation formation increases as the temperature of the outside environment falls, while the inside of the building is heated.

Key product features:

  • Reduces the risk of condensation formation inside the building frame in cold climates*
  • Improves energy efficiency by reducing draughts allowing insulation to work more effectively
  • Protects the building frame from decay by reducing the entry of wind driven rain and dust.

*If the membrane is to provide a continuous air tight layer, all joins, penetrations and discontinuities should be sealed

CSR Bradford offer a range of technical services including condensation modelling for project or climate specific applications by different construction types – advice should always be sought regarding high humidity environments such as indoor swimming pools or spas.

The drive for energy efficient buildings has resulted in higher levels of insulation in the roof space and walls, as well as reduced air leakage due to modern energy conscious building practices. As a result, this has dramatically changed the temperature and moisture balance within buildings, which has changed the location and frequency of where and when condensation is likely to form. When the surface where condensation wants to form shifts from outside to inside the building, condensation can potentially cause damage to the building frame, cladding and insulation, potentially allowing mould to grow, impacting your families health.

The Bradford Enviroseal™ Wall Wrap range of construction fabrics represent the latest in moisture control, vapour permeable water tight membranes. These products are designed to reduce the risk of condensation forming on surfaces within the building frame where it is undesirable. While allowing moisture to pass outward from the inside of the building, these sophisticated membranes prevent the ingress of water and dust from the outside environment both during and after construction.

These membranes may be used in all climate regions except where high humidity environments where cooling of the interior by air conditioning is the predominate climate control mechanism throughout the year. These membranes are ideal for lightweight clad construction such as fibre sheet cement, where high water holdout is typically a requirement of the cladding manufacturer.
