About Airtightness

All buildings need ventilation. What they don't need is air leakage. If your building isn't secure it will end up hitting you where it really hurts, in the pocket.

The key to controlling air leakage in buildings is the roofing and cladding, or building envelope. Get that right and the problem's solved.

Safety and sustainability are just a couple of the reasons why air tightness is high on the agenda. And with Part L Building Regulations about to get stricter, it's going to become an even hotter topic.

If you don't get to grips with air tightness, you'll fail the mandatory air leak test. And chances are you'll have cash or credibility slipping through your fingers. It might even be both.

For architects

Failing airtightness doesn’t just cause the costly problem of rectification. What’s even more difficult to put right is a dented reputation. Specify products with the quality and warranty that lasts. By choosing the right steel grade you can reduce the rate of rust and corrosion and make sure you meet even the most stringent building regulations.
For roofing contractors

Time is money, so getting installations right first time is key. By using cheaper quality fasteners you risk corrosion and failing air tightness, so it'll cost you more in the long term having to sort it out. Use the right fastener for the right job and you'll ensure a job well done.
For main contractors

Taking responsibility for entire projects also means taking liability for any failings and rectifications. Something as small and overlooked as a fastener can have a serious effect on airtightness, envelope corrosion, and your profits. You might think that a product warranty would cover this eventuality, but this is often not the case.
