Let your homes breathe with our reflective and water-resistant membranes.
Combine the high performance of our multifoil range with a breathable membrane, and you’ll get our reflective Breather Membrane range. Designed with a certified ‘W1’ watertight membrane, our BB range ensures exceptional thermal performance, effectively minimising condensation, temperature differences, and addresses all your energy loss hotspots. Not only will you save on your energy bills, but you’ll also benefit from enhanced comfort all year round.
A certified 3-in-1 product, providing high-performing insulation, breather membrane, and a radiant barrier—all within a single product.
Meet or exceed project requirements, whether used on its own or in hybrid solutions. Rigorous testing ensures compliance with the latest building regulations.
Multifunctional, lightweight and easy to install design that requires no specialist tools.
Each product is manufactured from up to 40% recycled plastic content and is fully recyclable at the end of its 50+ year lifespan.
New build, retrofit, timber-frame and DIY projects to achieve maximum performance, while maintaining a slim profile.
SuperFOIL’s BB range is the perfect external insulation solution for any project. It includes an additional reflective breather membrane, highly insulating waddings, and a radiant barrier.
The perforated design of the layers maintains breathability throughout the entire product while delivering superior thermal performance. With its ‘W1 watertight’ property, SuperFOIL BB products allow moisture to escape outside, minimising the risks of condensation damage to your property. When installed correctly, the BB range functions as a reliable secondary rain barrier.
Similar to our standard multifoil range, these breathable foils are also designed to be lightweight and easy to install, saving you space, time, and money.
Compared to many traditional insulation types, SuperFOIL SF19BB’s ease of installation, flexibility and multifunctional design minimise product wastage and installation time. Offering excellent value for money, our breathable insulation is perfect for new builds, renovations, and extensions. It is versatile enough to be used in both domestic and commercial projects, regardless of the project’s size and scale. This means you don’t need to purchase additional breathable products to protect your roof and walls while insulating!
