102mm Cavitylite – High-Performance Acoustic & Thermal Wall Insulation
Manufactured as a flexible roll rather than a batt, the 102mm Cavitylite is engineered for projects needing fast installation and long, continuous coverage. The roll format reduces joins, lowers installation time, and helps eliminate gaps that can cause heat loss and noise transfer. With its non-combustible A1 fire rating, high acoustic absorption, and excellent R-value, 102mm Cavitylite delivers reliable performance across a wide range of framed wall systems.
Key Features & Benefits

- Lightweight and easy to unroll, cut and position
- Compression packed to minimise storage and transport volume
- Maintains performance over its entire lifespan with zero maintenance
- Non-hygroscopic and resistant to mould, fungi and bacteria
Fire Performance & Safety
- Non-combustible Glasswool insulation
- Tested to SANS 10177 Part 5
- SANS 428 classification: A/A1/1
- EN 13501 classification: A1-s1, d0
