DuPont™ Tyvek® Metal is a roofing drainage underlay which drains away the condensation that can build up beneath the cladding on standing seam metal roofs. Tyvek® Metal roofing underlay is vapour-permeable, yet water-resistant and airtight. When used in combination with genuine Tyvek® accessories it can help to reduce condensation, improve overall airtightness, add thermal efficiency, and protect structural integrity. This underlay is a vapour-open drainage membrane with integral adhesive lap for use beneath standing-seam metal roofs. The open mesh of the product allows any condensate which can form beneath stainless steel, aluminium, copper and zinc roofs to drain away. Membrane may be installed over ply, OSB or softwood boarding. Suitable for SiPs. Besides allowing condensation beneath stainless steel, aluminium, copper, and zinc roofs to drain away, Tyvek® Metal also reduces sound transmission such as rain clatter and minimises material stress by permitting a degree of movement between the cladding and the timber beneath.
