Tyvek

Tyvek® breather membranes for pitched roof constructions provide excellent protection against external weather conditions whilst allowing water vapour to freely move out of the construction. With the new Tyvek® Enercor® membrane combined with some minor changes in installation practices, an important reduction of radiant heat losses can be achieved.

Tyvek® Supro/ Supro Plus
This durable Tyvek® underlay reinforced with a laminated Polypropylene nonwoven can be used in all supported and unsupported pitched roof applications, including warm, hybrid and cold roofs. It is specially designed for the rough installation related conditions of fully boarded roofs and is also applicable for profiled cladding (metal sheet), pitched roofs and wall applications. Also exists as Tyvek® Supro with an additional integral adhesive lap.

Tyvek® Enercor® Roof
Tyvek® Enercor® Roof is a vapour open roof underlay with a metallised surface which keeps radiant heat out in summer and helps to reduce heat loss in winter. Tyvek® Enercor® Roof should be used in unsupported (tiled/slated) roofs and fits also for profiled cladding (metal sheet) pitched roofs.
Tyvek® Enercor® membranes in combination with the VCL DuPont™ AirGuard® and some minor installation specialities offer significant energy savings of up to 15%.
 
 
Tyvek® Metal/ Tyvek® Proclad
This underlay is a vapour open drainage membrane with integral adhesive lap allowing eventual condensation beneath Stainless Steel, Copper and Zinc roofs to drain away. It is designed for use beneath standing seam metal sheet roofs over timber boarding and even more important over softwood boarding.
