Bradley Cameron, Technical Manager at the Tyvek® and AirGuard® Building Knowledge Centre, has been talking about Tyvek’s new wind uplift calculator tool, designed to give a more accurate assessment to ensure better outcomes.
He talked about roofing needing to choose exactly the correct roofing underlay, as getting it wrong could prove expensive in many ways.
A vital quality is withstanding ‘underlay ballooning’, whereby impact with the outer covering can dislodge tiles or slates; possibly causing injury, considerable damage or water ingress.
Identification of the ideal membrane can be tricky, which makes the new wind uplift calculator tool a crucial source of advice.
Important phrases such as “BS5534 compliant”, in reference to the BS5534 standard, which splits the UK into five zones, each with a different requirement of resistance to wind uplift, plus “specifications available” or “all zones compliance” may offer a sense of security, but when used without the certified wind uplift figure, mean extremely little in terms of performance.
The wind uplift calculator tool from DuPont™ Tyvek® offers a new, tried and tested solution that surpasses the aforementioned BS5534 zonal criteria.
Quick, easy to use and free, all you need to do is enter the relevant information by selecting drop downs in these seven categories: Country (England, Scotland or Wales), wind zone (from the five wind zones identified in BS5534), terrain, building height, ceiling type, distance from water (sea, lakes, rivers, etc.) and slope.
Virtually straight away, it will assess individual aspects and recommend the membrane that’s ideal for the job; for every project, wherever it may be, it is unique.
Choosing the correct roofing membrane to be durable throughout the years is vital to any roofer’s reputation, peace of mind and the building owners’ financial risk.
