Breathable Multifoil Insulation
Protect Your Project With Our Breathable Insulation
Here at SuperFOIL, we produce the UK’s highest performing, breathable, multifoil insulation.
Our ‘BB’ range utilises a highly breathable, reflective top membrane which provides you with a secondary rain barrier, whilst allowing moisture to escape safely away. The remaining layers are perforated which keeps the whole product breathable, whilst still providing high thermal performance.
Our range of multifoil insulation is CE-certified as a breathable membrane and water barrier. If you are searching for a reliable and affordable insulation system, you needn’t look any further. By working alongside SuperFOIL, you can take comfort in the fact you are applying a highly reliable and regulated product.
As with the rest of our multifoil range, our products are also 3-in-1. Our breathable loft lining provides highly efficient insulation, a radiant barrier, and a helpful membrane. Not only will you save on your energy bills, but you’ll also protect your home from condensation! Over time, moisture can weaken your foundation and compromise the structural integrity of your building. Choose our insulation to keep your house safe and at a comfortable temperature, whatever the weather!
Breathable Membrane & Insulation In One Layer
Using our range of breathable multifoil insulation saves you from completing unnecessary work. Our breathable lining range means you only have to install one product to protect and insulate. Multifoil insulation will always be the ultimate convenient solution since it is reflective and water-resistant without additional measures. You could easily reduce the time it takes to insulate your new build project.
As well as the benefits of water resistance, the breathable range comes with a built-in 100mm overlap on the membrane. You won’t have to trim or confront excess material at joints.
The multifoil range can be used as part of the ‘DUET’ system; use your chosen SuperFOIL breathable insulation internally and externally for a durable solution. It can also be used in a ‘COMBI’ installation, meaning that our products are fully compatible with other types of insulation. If your loft insulation isn’t effective enough alone, you can pair our multifoil with mineral wool or foam boards for convenience. Of course, our insulation technology and resistance membrane is effective enough alone! Still, removing current material in your walls and your flooring can waste time and effort.

Applications









Roof Insulation Application



Do you have a roofing project to complete? No problem! Our breathable multifoil insulation can be used in virtually any roofing project, whether new build or retrofit. Our insulation works as a breathable roof membrane and loft insulation in one layer. Our 3 in 1 insulation products save on time and money. Our insulation is ideal for external use, providing both insulation and a breathable roof membrane in a single product.
The SuperFOIL breathable multifoil insulation range is the perfect solution for those troublesome retrofit projects. Our BB products provide a significant performance boost with minimal build-up for when space is limited. For new build projects, our breathable loft lining helps to minimise costs whilst allowing innovative design. Our breathable multifoil insulation creates a breathable roof- keeping your property warm in winter and cool during the summer months.
Wall Insulation Application
Our breathable membrane multifoil insulation range achieved a W1 waterproof rating, which is suitable for both roofs and wall insulation applications. The ‘BB’ range is commonly used to insulate walls externally, allowing any moisture build-up inside the wall or stud work to escape. This also provides additional protection for your property in the form of a secondary rain barrier.
You could achieve an approximate U-value of 0.32 in your wall by using a single layer of SF19BB. Adding just 25mm of mineral wool between the studs would increase to 0.28U whilst still ensuring the wall is fully breathable.



Floor Insulation Application



Did you know that up to 10% of a home’s energy escapes through flooring? This is down to poor floor insulation. High-quality underfloor insulation, when correctly installed, will improve the energy efficiency of your home and reduce your energy bills. Our innovative insulation solutions are easy to install and highly effective.
The SuperFOIL breathable multifoil insulation range is suitable for suspended floor and solid floor applications. Our breathable insulation also gets to work instantly, so you can start increasing your energy efficiency immediately.
Breathable Roof Membrane
Why Choose Our Breathable Roof Membrane Insulation?
With a vapour resistance of 0.115MNs/g, our range of breathable roof membranes offers the same benefits as a traditional breather membrane but with the bonus of thermal properties. This means you can always be confident using our product, knowing it will not cause any condensation issues.
Our breathable roof membrane insulation is easy to install. Starting at the bottom of your roof, roll out as a continuous layer over your rafters/joists horizontally and staple into place.
The built-in overlap system of our breathable insulation ensures you will consistently achieve the correct overlap between joins. Meaning you just have to peel the backing on the integrated tape to provide an airtight finish for ultimate effectiveness.
By following these methods to install your SuperFOIL products, you could see an increase in performance of up to 15% against traditional forms of insulation.
