Building on the existing range of applications for its Supafil blown-in glass mineral wool products, Knauf Insulation’s Supafil CarbonPlus has received British Board of Agrément (BBA) agreement for filling residual cavities in existing partially filled masonry cavity walls.
The BBA agreement means that one solution can now be used to treat multiple types of hard-to-treat properties, including existing masonry cavity walls with built-in partial fill insulation. Supafil CarbonPlus can be used in a variety of partial fill constructions such as those incorporating polystyrene backed blocks, as well as EPS, XPS, PIR and phenolic foam boards. The minimum residual cavity must be no less than 40mm.
Although many partially filled properties are designed to have a 50mm residual cavity, this is often not the case in practice and the vast majority end up with a narrower residual cavity. Therefore it is essential that an appropriate and correctly certified solution is used in these instances.
Supafil CarbonPlus has been specifically designed for installation into narrow cavities below 50mm and has undergone rigorous testing with the BBA to prove its suitability for this application.
Dave Khan, Technical Marketing Manager at Knauf Insulation comments: “We are committed to supplying high quality products that are fully backed by third party testing and accreditations. Our Supafil range already delivers proven benefits to contractors and specifiers alike and this new BBA agreement further strengthens the range’s appeal. What’s more, it enables contractors to secure Cavity Insulation Guarantee Agency (CIGA) hard-to-treat guarantees for the work they carry out, as well as accessing funding via the Energy Company Obligation.”
The Supafil CarbonPlus system consists of a high performance Supafil product that is not restricted by temperature, enabling installers to install it all year round and it is compression packed to increase the amount of material that can be loaded onto each vehicle. Additionally, installers and contractors can use existing blowing wool machinery to install the product.
