Product is tested to EN 13859-1 and is CE certified. LABC Certified What are the key qualities of breathable roof membrane? Our breathable roof membrane option offers a variety of qualities including: Breathable membranes and roofing felts are a fundamental element of most new build and refurbishment projects. Their adaptable, multi-purpose use is seen by specifiers, merchants and installers as the optimum solution to under-slating requirements. Breather membranes play a key role in protecting buildings and occupants from the elements. In addition to improving energy efficiency, this breather membrane offers long-lasting protection against several threats to building integrity, including condensation and infiltration by water and air. Our Heavy Duty 115 g/sm breathable roof membrane is of equivalent quality but offers a much more cost effective alternative to branded membranes like Cromar and Tyvek. This type of roof membrane contains special stabilisation additives which extend its resistance to UV radiation which allows installers to perform assembly of the final roof covering without the added pressure of time-delays affecting the material’s durability. Breathable roof membrane is equally suitable whether draped unsupported over rafters or laid directly over insulation. The outer layer forms a functional waterproof surface, the middle layer is the breathable waterproof membrane and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof. What are the main applications of breathable roof membrane? When it comes to the application of breathable roof membrane, it is ideal for: Engineered for use in a fully supported or unsupported tiled, slated or metal roof system. Transporting moisture resulting from any ingress through a primary roof covering into a roof drainage system Provide a barrier to minimise the wind uplift load acting on the slates or tiles Provide a secondary barrier to the ingress of wind driven rain, snow and dust Provides robust weather protection before the installation of the primary roof covering EU approved for use in Warm and Cold, Ventilated and Non Ventilated Roofs Available in a 1.5m width as standard to conform easily to any typical roof configuration or the individual working practices of the installer This is a water vapour permeable membrane with a mass of 115gms suitable for use in all types of domestic and commercial roof applications.

## Questions & Answers

**Q: I need to fix a couple of patches of membrane on top of existing membrane inside the loft.  What is the best way to fix them.**
A: The patch you repair should be tucked under the lower overlap

**Q: How do I attach this to my sheathing? tape  or nails or both?**
A: Galvanised clout nails or stainless staples fixed with a suitable professional stapler

**Q: Which way up do you install this? Logo out to sun/blank side down? Does it matter?**
A: Logo to the sun so you can read it. As it gives you the dotted overlap line to work to.

**Q: Suitable for under gapped cladding? Installed like, vertical cladding, breather membrane, insulation, foil-tec... would it make the walls waterproof?**
A: Cant see why not as long as it is breathable. Check with the supplier to be sure

### ⭐⭐⭐⭐⭐ Roofs garden rooms Great product
*by R***Y on 29 November 2025*

Excellent membrane used on many jobs. Roofs and wrapping garden rooms. Would definitely buy again

### ⭐⭐⭐⭐⭐ Great product
*by A***R on 19 October 2024*

Arrived promptly, well packaged and great quality at a good price.

### ⭐⭐⭐⭐⭐ Waterproof. Wind proof. It did exactly what I needed it to do
*by B***N on 26 September 2020*

Bought to cover shed as a wrap and breathable membrane before adding feather edge as well as using on roof over OSB before adding felt. Heavy rain and gale force wind hit before had chance to put on roofing felt, and only managed one side of feather edge, in the dark, in an attempt to protect shed from the storm due. This product is DEFINITELY waterproof and has kept shed from roof to base completely dry, except where the wind blew corners up on roof. Amazing product and easy to use. The underside of membrane is white so adds brightness inside shed if want to leave. I’m pretty fussy and you’re able to get a nice, crease or wrinkle free finish as an internal liner. Very pleased with results.
