Product Details

Looking for a two-in-one insulating venting membrane when working with timber frame and modular building constructions? YBS BreatherFoil will outperform traditional breathable membranes and greatly increase the U-value of a timber frame wall.

Whether pre-fabricated or assembled on site, you’ll be sure of maximum flexibility when detailing timber frame walls or dormer cheeks, without the expense of thicker timber frames or higher priced materials. 

BreatherFoil’s unique design allows the application to breathe while offering improved thermal performance. Its core bubble profile offers great thermal benefits by trapping air within the small bubble pockets. The outer aluminium foil layers increase the overall thermal performance, due to their high reflectiveness.


• Two-in-one insulating and breathable venting membrane

• Suitable for timber frame and dormer walls

• Effectively reflects heat back out of the room

• Allows moisture to pass through, reducing risk of condensation

• Up to 42% reduction in heat loss (based on a single layer in a timber frame)

• Non-degradable for long-lasting thermal performance

• Excellent tensile and tear-resistance strength

• Two layer build-up and only 4mm thick

• Flexible, lightweight and easy to install

• Minimal waste compared to traditional insulation products

Rated 4 out of 5 by from Foil Faced Breather Membrane Ideal for use on a timber frame section of my project with a blockwork cavity wall. Make sure the foil is facing the cavity.

Rated 5 out of 5 by from YBS foil membrane . This stuff is very tough and works very well brilliant vapour barrier water just runs away .

Rated 5 out of 5 by from Seems good Light to lift, easy to cut to size, seems robust. Will have to wait and see about the insulation effects when the weather gets cold.

Rated 5 out of 5 by from Good Quality Membrane This is a good quality, hardwearing product, much thicker than ordinary bubble wrap. It is properly waterproof, and breathable as well as offering a very small amount of insulation. We've used it under the cladding on a number of garden buildings and it certainly helps with reflecting heat away so the inside stays cooler.
