“Is it cheaper to buy Permo Air with integral tape rather than buying Permo Air PLUS additional tapes?”
“What ARE the added benefits of having an air open membrane with an integral tape?”
To talk straight, we’re asked…”WHY would I buy Permo Air with integral Tape versus without”
Here we’re going to take a look at a number of reasons why our new Permo Air with Tape is a smart choice…
Let’s jump straight into the most common question - is Permo Air with Tape more cost-effective?
Buying Permo Air with integral Tape on average saves you 15%* in comparison to buying Permo Air and tapes separately. Why? To cover the entire 50m length of Permo Air, you would need to purchase an additional 2 x 25m roll of tape, increasing the costs.
The recommended headlap for roofs above 15° for Permo Air without Tape is 150mm. However, Permo Air with integral tape is designed to be installed with a reduced 100mm headlap, giving you an additional 5% coverage area per roll**.
Permo Air with Tape is available in 2 sizes, 1m x 50m, and 1.5m x 50m giving you the opportunity to select the optimal size membrane for your roofing project, reducing waste, having the potential for further savings.
At Klober, we like to understand the challenges and stresses our roofers may face day-to-day on their jobs, and we aim to make their lives’ easier…
“Is Permo Air with Tape easier to work with and to install?”
Whilst using adhesive tapes to seal your roofing underlay headlaps is a fairly straight forward process, it can sometimes be a little tricky up on the roof, particularly on windy day. Having the integrated tape simplifies the process, allowing you to join the headlaps adhesive to adhesive for an easy, secure installation.
Permo Air with Tape can be installed in all (reasonable) weather conditions.
Improving the roofing standards by using high quality, effective components in line with current building regs is important to us at Klober.
“Does Permo Air with Tape have any additional quality or safety benefits?”
Following an increased number of problems with lightweight membranes ‘ballooning’, a new wind speed map of the UK was introduced in 2015. In response to this regulation it is a requirement that when installing Permo Air in a typical cold roof, without counter battens, in UK wind zones 4-5, you MUST tape your headlaps with either a membrane that has its own integral tape OR with a separate membrane adhesive tape like Permo Tape.
Remember: It is against BS 5534 requirements to secure headlaps under battens without any additional means of adhesion such as using a membrane with integral tape or separate tape in UK wind zones 4-5 in this situation.
At Klober we would encourage installers to seal their headlaps on all projects as best practice for a higher quality fix and we guarantee Permo Air with Tape will ensure BS 5534 compliance in all UK wind zones.
Apply the integral strips to each other for a longer lasting, stronger adhesion.
