YBS BreatherFoil FR For Walls
Insulation and Venting Made Easy
YBS BreatherFoil FR for Walls is a thin and flexible 2 in 1 insulating and venting membrane, designed specifically for external walls including timber frame and modular buildings.
At only 4mm thick, this product replaces the need for a traditional breather membrane while insulating and without increasing the depth.
YBS BreatherFoil FR For Walls for Timber Frames can be installed in a factory scenario or on site by simply stapling the material directly onto timber OSB Boards allowing the reflective foil to face the external of the property.
We advise BreatherFoil to be overlapped by 75mm and the horizontal overlaps should remain untapped, to allow any moisture to dissipate. We recommend the vertical joints to be taped and sealed using Thermaseal Foil Joining Tape.
This product creates a totally draft and moisture free building during construction, and also when the project is complete!

How to install BreatherFoil FR Insulation
How to install YBS BreatherFoil Insulation
-
Preparing The External Wall For Insulation
Prepare for the BreatherFoil installation by removing any Exisiting Cladding and exposing the OSB/Sarking board.
-
Attaching The Initial Layer Of BreatherFoil
Unroll the BreatherFoil Horizontally across the wall and staple it directly to the external timber boarding, at a minimum of 300mm intervals.
-
Where A Vertical Joint Occurs
Where a vertical joint occurs, ensure a minimum overlap of 100mm & seal using ThermaSeal Foil Joining Tape.
-
Where A Horizontal Joint Occurs
When rolling out the next roll above the first, horizontal joints need to be created, ensure a minimum overlap of 75mm, leaving the overlaps untaped.
-
Attaching The Second Layer Of BreatherFoil
Staple the BreatherFoil directly to the external timber boarding as before, at a minimum of 300mm intervals.
-
Vertical Taping The Perimeter
Once the wall is fully covered, begin to seal the vertical perimeter using ThermaSeal Foil Tape, leaving the top and bottom untaped.
-
Install Timber Battens
Apply a layer of timber battens (minimum of 25mm), perpendicular to the rafters at minimum intervals of 400mm.
-
Install The External Finish
Finally apply the external finish/cladding in accordance with the manufacturers certification, fixing instructions & good building practice.
Does BreatherFoil FR breathe?
BreatherFoil is a venting membrane, meaning the material itself is not breathable. However, when the material is fitted, the horizontal overlaps are left un-taped. This allows breathability through the laps.
Is BreatherFoil FR Certified?
Yes, BreatherFoil FR is UK Manufactured, and is accredited by both BDA and STAS.
What is BreatherFoil equivalent to in PIR?
In a Wall, BreatherFoil FR has a certified R-value of 0.79. This results in our 4mm insulation being equivalent to 18mm PIR Insulation
Does BreatherFoil need to be fixed on a Plywood?
Yes correct, BreatherFoil FR must be stapled on a continuous timber board. The timber OSB/Plywood is to be fixed to the external of the stud, then followed by our insulation. We would not recommend stapling BreatherFoil directly on timber vertical studs.
Whats does FR Stand for?
FR stands for Fire Retardant. This means a chemical is added to the material to prevent the start or slow the growth of fire.
How is BreatherFoil FR fitted?
BreatherFoil FR is simply stapled directly on to timber plywood or OSB Boards. BreatherFoil is cut by using a craft knife or multifoil scissors. These items can be found in our Multifoil Insulation Fitting Kit.
Does BreatherFoil replace a standard breather membrane?
Correct, fitting BreatherFoil FR on the plywood sheathing replaces the required for a standard breathable membrane. Whilst being only 3mm thicker than a standard felt, it provides excellent additional thermal benefits.
