Permavent Breather Felt - Advanced Roofing Supplies

Breather Membranes

Advanced Roofing Supplies specialise in the supply of roofing materials. - That’s it! - That’s what we do!

We supply roofing materials, natural slate and concrete tiles, ridge tiles, breather membranes, boards, battens, nails, sealants, roof windows and lead. We supply plastic fascia, rainwater gutters and underground drains.
We also offer everything for the installation and repair of Fibreglass roofing.

Our aim is to be a one-stop-shop for the trade or anyone else who has need of us, and with Advanced Roofing our first price is our best price.

Is that all? - No, because we have one other trick up our sleeves, years of hands-on experience of fitting roofs on houses.

We know the trade, because we are the trade.
We can give off plan estimates for new roofs or offer advice on the best way to tackle repairs.

And we don’t burden our staff with sales targets, so no one is under any pressure to make a sale at the expense of you not getting the best advice.

three layer polypropylene structure with the magic functional film in the middle	PERMAVENT MAX breather membrane is a three-layer product with increased GSM (grams per square metre) and strength parameters. Its high vapour permeability (1343g/m²/24h) makes it ideal for building industry as a membrane for insulated pitched roofs of all kinds, both fully boarded and conventional ones. It is also an ideal tough weather resistant housewrap.
Due to high performing functional film (polypropylene) and increased strength parameters in the production process, the product has an upgraded degree of watertightness ( well over 6000mm H²O), which means that it is highly resistant to water and moisture while providing the opportunity to carry out assembly work in any atmospheric condition. Special UV stabilising agents allow the product to have an increased resistance to UV rays (even up to 4 months !!), meaning that the final covering of the roof can be delayed to a later stage. PERMAVENT-MAX can be used on cold vented, non–vented, warm deck and hybrid roofs (habitable roof space). The name speaks for itself. If you need maximum performance PERMAVENT-MAX is for you! Use of the latest technical inventions and very efficient technology made it possible to offer a product of superb quality at an affordable and attractive price. There are special imprints on the product that facilitate overlapping, and the original label and the Permavent logo guarantee the stability of the product's quality and its genuineness. Due to PERMAVENT-MAX membrane the life span of your attic and the roofing system will be significantly increased, which guarantees that your house will have dry and healthy climate. Overlaps of Permavent membrane should be joined with special Permavent-Tape. NOTE: Permavent-MAX is also used as a housewrap in skeletal construction and under siding.
