Overview
- Free-flowing granules pour directly from the bag, filling tight, complex spaces inaccessible to standard glass wool or board insulation.
- No cutting needed; creates a seamless, continuous heat-trapping surface.
- Ultra-lightweight: Made of highly aerated particles with 90% air, enabling easy transport, handling, and lifting into lofts without stressing structural elements.
- Permanently protects against fire, remains non-combustible and thermally stable up to 1300°C.
- Decay and pest resistance: Its inert mineral makeup ensures long-term stability, preventing decomposition, deterioration, and attraction of insects and rodents.
