2 in 1 Multifoil and Breathable Membrane
We here at Multifoils Direct are the leading distributor of BreatherQuilt and now have a live SALE.
It’s also worth us noting that YBS BreatherQuilt is a cheaper and higher-performing alternative to TLX Gold.
This product is a high performing 2 in 1 Insulating Multifoil, that is Breathable. Designed for Insulating Over Roof Rafters. It, therefore, replaces the need for a traditional breather membrane / felt.
Breatherquilt includes a True Aluminium Foil which reflects vital heat during the winter, which would be lost with an ordinary breather membrane.
BreatherQuilt contains 11 perforated layers and includes a fully waterproof breather membrane and a reflective True Aluminium Foil on the inner face. It also now includes built-in double-sided tape – so no need to buy this separately!
Installing YBS BreatherQuilt
You can install BreatherQuilt over the rafter using either a Drape Detail (Single Batten Required) or a Counter Batten Detail (Double Batten).
We advise the BreatherQuilt to be fixed directly on the rafters with either staples or nails. At only 7mm when compressed BreatherQuilt takes up minimal roof space too.
We then recommend overlapping BreatherQuilt on the horizontal sections by 100mm and sealing using the built-in double-sided tape!
On vertical joints, ensure BreatherQuilt is taped with Thermaseal Weatherproof Tape! For every 10 rolls of BreatherQuilt, we advise 1 roll of Thermaseal Weatherproof tape.
Can YBS BreatherQuilt Benefit your project?
BreatherQuilt is fully LABC and BBA Certified for New Build and Refurbishment projects. Here at Multifoils Direct, we provide solutions that include BreatherQuilt to achieve building regulations with no rigid board insulation. BreatherQuilt is also used in our TyvaQuilt System and our 3-Layer Quilt System.
YBS BreatherQuilt is equivalent to approx 55mm of Rigid Insulation. Kingspan & Celotex are popular brands of Rigid Board Insulation.

How to Fit BreatherQuilt over Rafter
-
Install First Layer of BreatherQuilt
Starting at the bottom of the roof, roll BreatherQuilt across the rafters and staple in place at 300mm intervals. Ensure BreatherQuilt is draped in-between each rafter as opposed to being pulled taught. It is vital that a 10mm clear gap is formed at the center of all rafters. The gap is between the top layer of BreatherQuilt and installed tile batten.
-
Fixing and Cutting
Ensure BreatherQuilt is stapled at 300mm intervals, using min 14mm deep staples, or nails. BreatherQuilt can be cut with either Multifoil Scissors, or a Cutting Knife. Both the cutting tools, along with a Staple Gun & Staples are available in our Multifoil Fitting Kit.
-
Horizontal Overlaps
Once the first run of BreatherQuilt is fully fixed, and is draping into the rafters, proceed next by taping a line of 50mm Thermaseal Double Sided Tape along the edge of the material. Install the next layer of BreatherQuilt in the same manner as the first. Overlap the first and second layer by 100mm, ensuring the double sided tape is secure and sealed.
-
Vertical Joints
Where 2 layers of BreatherQuilt meet on vertical sections, we advise these layers to be butt jointed, not overlaps. These joints should be taped over with a suitable 50mm waterproof duct tape.
-
Final Detailing
At the eaves BreatherQuilt should extend onto a suitable eaves carrier. Proceed with tile/slate battens and tile/slates.

What does BreatherQuilt consist of?
BreatherQuilt consists of 11 itch-free layers including True Aluminium Foils as the Inner layer. BreatherQuilt’s external layer is a high tensile breathable felt. The other 9 layers consists of recycled waddings, PE Foams, and other reflective foils.
Is BreatherQuilt harmful?
BreatherQuilt contains no harmful fibres and does not release any toxic gasses when cut or installed. When installing BreatherQuilt, there is no requirement for any masks, PPE or gloves.
What thickness is BreatherQuilt?
BreatherQuilt is available in just one thickness, which is 40mm at a relaxed thickness and will compress down to 7mm.
Do BreatherQuilt require airgaps?
To gain the best thermal performance, we recommend a minimum cavity/batten of 25mm both sides of the insulation. This is to allow the product to expand and reflect. If a cavity is removed, the performance would reduce by approx 20%.
Is BreatherQuilt fireproof?
BreatherQuilt has a Class E Euro Fire Classification Certificate. BreatherQuilt is not fully fire-proof, however the true aluminium inner layer are flame proof, meaning if a naked flame touches the product, it will smoulder as opposed to spreading.
What’s the difference between BreatherQuilt and SuperFoil SF19BB?
BreatherQuilt and SF19BB are both breathable multifoils for over rafter use. BreatherQuilt is UK manufactured and is fully certificated by both LABC and BDA. BreatherQuilt also has a true aluminium foil as the internal layer, compared to a met-pet foil layer.
