Knauf Supafil Cavity XL 033

Knauf Supafil Cavity XL 033 is an innovative blown mineral wool insulation specifically developed for the thermal insulation of wide cavity walls in new-build projects. This system provides efficient, seamless and durable insulation without cutting waste or the need for additional material storage on site. Thanks to its unique composition and installation method, the cavity is completely filled, resulting in excellent thermal insulation and improved energy efficiency.

Benefits of Knauf Supafil Cavity XL 033

• Excellent thermal insulation: Helps prevent heat loss and contributes to an energy-efficient building.
• No risk of settling: The blown mineral wool remains stable throughout the lifetime of the building.
• Water-repellent and vapour-permeable: The material is treated with silicone, helping to prevent moisture absorption while allowing the construction to remain breathable.
• Sustainable and environmentally conscious: Made largely from recycled glass and free from harmful chemicals.
• Fire safety: Classified as Euroclass A1, meaning it is non-combustible and does not contribute to flame spread.
• Quality assurance: Process monitoring and certification under the supervision of SKG-IKOB and Insula help ensure consistently high insulation performance.
• Weather-independent installation: Can be installed in a wide range of weather conditions, helping to minimise delays on site.
• Healthy indoor air quality: Certified to the stringent Eurofins Indoor Air Comfort Gold standard, contributing to a healthier indoor environment.

Application and installation

Knauf Supafil Cavity XL 033 is blown into the cavity through the inner leaf. Thanks to its special fibre structure, the material distributes evenly throughout the cavity, helping to prevent thermal bridges. The system is suitable for cavity widths from 100 to 250 mm and provides a permanent, even distribution that helps minimise air leakage and heat loss.

Supafil Cavity XL 033 can be installed quickly and efficiently without requiring additional material storage on the construction site. Installation can be coordinated with other construction activities, helping to create an efficient building process with minimal disruption.

DECLARE contributes to sustainable buildings

DECLARE certification can contribute towards credits in green building rating systems that focus on the use of sustainable and healthy construction materials. These include leading programmes such as WELL, LEED and the Living Building Challenge. Supafil Cavity XL 033 can therefore contribute to more sustainable and healthier buildings designed to meet stringent environmental standards.

SUPAFIL and the benefits for indoor air quality

As people spend a significant amount of time indoors, indoor air quality is becoming increasingly important, particularly for older people, young children and those with health concerns. SUPAFIL Cavity XL 033 meets the stringent Eurofins Indoor Air Comfort Gold requirements. This certification demonstrates its low emissions and suitability for creating a healthy indoor environment.
