Fletcher Insulation’s Sisalation® Vapawrap™ range of vapour permeable construction fabrics represent the latest in moisture control, vapour permeable watertight membranes.
These products are constructed to reduce the risk of condensation developing on surfaces within the building envelope where they are unwanted. At the same time as allowing moisture to pass outward from the inside of the building, these modern membranes prevent the entry of dust and water from the outside environment both during and after construction.
In contrast to traditional foil faced sarking products, the high water vapour permeability of the Sisalation® Vapawrap™ range of vapour permeable membranes permit the contained escape of moisture from within a building along with limiting the ingress of liquid water and dust from the external environment.
