Questions & Answers


Can this product be used to cover single block work, before cladding?


Tyvek® Housewrap may be fixed to masonry with a suitable anchor fixing system or a masonry nail/screw and EPDM rubber washer. Fixings should be at maximum 500mm centres. Tyvek® Butyl Tape (double sided) may be used to fix the membrane in addition to the mechanical methods suggested above. Tyvek® Primer can be applied to chalky or porous masonry to seal the surface and improve adhesion before applying adhesive tape.  


Can I use this to line the inside of a shed prior to insulating it?


The product is designed be the the outermost layer before the structural layer and will provide a breathable layer before insulation - so yes this would be absolutely fine. 


Can this be used on roofs under tiles?


No, this product is for use on the walls only.
