BS5534: DuPont™ Tyvek® sails through new wind resistance tests

DuPont Tyvek Breather Membranes – Slating and Tiling

March 2015 – As building regulations become ever more stringent, so DuPont™ Tyvek® keeps pace by virtue of its inherent quality, longevity and proven performance. Always at the leading edge of the industry, all DuPont™ Tyvek® roof underlays have passed the necessary tests for the new BS5534 guideline (Code of practice for slating and tiling) which sets strict new requirements for resistance to wind uplift in pitched roofs. Taking effect as of March 1, 2015, the new requirements are defined by different zones for wind exposure (from 1-5) and for varying installation and site conditions.

Three advanced breather membranes from DuPont have sailed through qualification for the new code, meeting the new criteria for all wind zones (including market leading DuPont™ Tyvek® Supro), thus offering a comprehensive range of BS5534 compliant membranes with full certification. DuPont is a world-class science company with a long-standing commitment to ensuring the fitness of its products in terms of performance, sustainability and safety – and these results confirm its leadership in the field.

The BS5534 compliant membranes from DuPont Building Innovations are:

• DuPont™ Tyvek® Supro, the premiere breather membrane with an outstanding track record of protecting roofs against wind and rain, while also enhancing energy efficiency

• DuPont™ Tyvek® Supro Plus, which offers the above benefits together with an integral adhesive lap tape designed for use in the Tyvek® ‘sealed roof system’ for increased energy performance and now also for additional security against wind uplift.

• DuPont™ Tyvek® Enercor Roof, a metallised version of the vapour-open roofing membrane designed to optimise the thermal performance of a building, now leading the field for wind uplift resistance.

These membranes are suitable for use in pitched roof systems at maximum batten gauge in all five categorised wind zones, when the products are installed in line with BBA certificate 08/4548 and DuPont’s own trusted technical guidance.

DuPont™ Tyvek® proposes a simple, practical and professional solution to meet the new wind uplift requirements, without the need for any special installation processes or accessories. All three versions of the renowned membrane have a BBA certificate, full CE marking and a Declaration of Performance (DoP) and each can be easily installed, the battens fixed, and details for general weather-tightness checked to offer an optimum solution to the multiple requirements of the modern building envelope.
