To preserve the performance of metal roofing solutions, DuPont™ Tyvek® offers a suite of solutions specially designed to control condensation and heat build-up.

 

 
 
 
 
 
 
 
 
 

 

Since metal roofing is highly vapour-resistant, it is prone to condensation build-up on the underside of the sheets. Unless effective measures are taken, this trapped moisture can drip back onto the insulation and fittings, setting a cycle of deterioration in motion.

Protection That Lasts

Two key factors can weaken the weatherproof properties of profiled or standing seam metal cladding: natural weathering and the effects of thermally induced movement caused by temperature fluctuation. In both cases, the damage can include displaced waterproof seals between sheeting laps, and enlarged penetration points where the sheets are fixed. As a result, there is a greater risk of external moisture getting through – for example, in driving rain. DuPont™ Tyvek® helps to minimise the risk of this happening – by protecting your roof and your investment long-term.

DuPont™ Tyvek® offers advanced, coordinated solutions that are engineered to improve and conserve the performance of fully supported profiled metal sheet roofs.

The high vapour permeability of the Tyvek® underlay combined with high performance AirGuard® air & vapour control layer (AVCL) permits the release of vapour through and away from the insulation. The high water resistance of DuPont™ Tyvek® and AirGuard® membranes also prevents any condensed moisture beneath the outer cladding to re-enter the construction, thus ensuring the insulation operates in a dry environment. Tyvek® Metal goes even further by creating space for effective drainage and offers a reduction in sound transmission normally generated by structure-borne sounds such as rain-clatter.
