The advanced breather membrane for modern building gives contractors the assurance they are complying with BS 5534:2014
Following extensive refurbishment of the property, a sympathetic new addition complements the main structure to create one large, luxury, four-bedroom house, complete with pool and terrace.
The project was a challenging one, as building work had to be carried out in accordance with contemporary codes. Also, its position, perched high on cliffs above the shore line, meant that ensuring the structure was protected from the harsh Atlantic coastal weather was paramount.
When it came to construction of the pitched slated roofs, contractors Marnick Roofing Ltd of Falmouth opted to use their favoured underlay material: the advanced breather membrane DuPont™ Tyvek® Supro Plus. Paul Marks, of Marnick Roofing Ltd, explained why: “The choice was clear, not only in terms of the quality of the product, but also because we know we can depend on great service from DuPont. This is a highspec project in a spectacular natural setting and we are proud to be involved.”
DuPont™ Tyvek® Supro Plus is long established as a proven performer in terms of water-shedding, moisture management, airtightness and enhanced thermal efficiency. It is naturally vapour-open, but also wind and water-tight. This is due to the millions of micro fibres that bond together to form a maze that is impermeable to air and moisture, but that allows water vapour to pass through it.
Benefits of DuPont™ Tyvek® include:
- Unique high-quality single layer construction
- Naturally vapour-open, but also wind and water-tight
- Offers unrestricted compliance with BS 5534:2014 for all wind zones and at all altitudes
The exposed location of the property meant that DuPont™ Tyvek®, which boasts winduplift resistance, together with trouble-free installation, was the perfect choice.
All three DuPont™ Tyvek® BBA approved roofing underlays offer unrestricted application when tested in accordance with BS 5534:2014, with no counter battens required in any zone:
- DuPont™ Tyvek® Supro
- DuPont™ Tyvek® Supro Plus (with integral tape)
- DuPont™ Tyvek® Enercor roof
This means contractors have assurance that they are fully compliant – not only with the code, but with all the weathering and thermal performance expectations of an advanced breather membrane.
