Designed for modern wall, roof and retrofit applications where moisture management and airtightness are critical.
BB Range are external insulations with breather membrane.
- Vapour-permeable, breathable membrane construction.
- Controls condensation while maintaining thermal performance.
- Provides thermal insulation, radiant barrier and secondary weather protection in one system.
- Suitable for new build and retrofit applications.
- Manufacturer-tested and building regulation compliant
Important – System use & certification
SuperFOIL BB (Breathable) insulation products are designed for vapour-open construction systems, where moisture management and secondary weather protection are required.Certain SuperFOIL breathable products are used as components within approved wall insulation systems, including systems assessed under KIWA Agrément, when installed as part of a complete, correctly designed build-up.
Certification applies to the system configuration, not to individual products used on their own.Correct installation, layer sequencing and adherence to system guidance are essential for regulatory compliance.
U-Value calculation & regulatory compliance
Thermal performance depends on the full construction build-up. Use the official SuperFOIL U-Value Calculator (available on the Home Page or Product Page) to verify compliance and optimise your insulation design.
