Cavipor® is a non-combustible mineral-based insulation foam system that can be easily processed. It is particularly suitable for subsequent energetic renovations of buildings constructed of double-wall masonry. 

In general, this measure of retro-fitting by insulating the cavity wall has an amortization period of 5-7 years making it a highly profitable investment – both economically and ecologically. In addition to previously established systems like stone wool, glass wool, EPS beads, synthetic resin foam, and recycled shredded paper, Cavipor® now offers a new system that combines the advantages of a hydrophobic and open-pore mineral insulation material with the fast, safe, and seamless processability of a self-sealing foam system. In contrast to most other systems on the market, Cavipor® foam can be disposed of along with construction waste without having to painstakingly separate it during renovations or demolitions, or re-used as a foundation material.

Cavipor® is the world's first 3-component system for manufacturing a mineral-based in-situ foam. It was developed at BASF through 8 years of intensive research with over 5000 test recipes, and is protected by multiple patents. The system received the European Technical Approval (ETA-19/0240) in 2020.
