Glasswool Roll / Blanket
−50°C to +230°C
Main applications
- The right balance of wall sound absorption and thermal insulation
- with a cleaner installation
Key Features
Outstanding sound absorption (high NRC)
A fine cellular structure absorbs sound energy — the essential material for partition wall noise control
Dust-free, comfortable installation
Special film wrapping stops glass fiber release at source, minimising skin irritation
Top-grade fire safety
Non-combustible, Class 1 flame rating — no toxic gas, and compliant with fire-compartment regulations
Strong recovery and tight fit
Recovers instantly after compression, filling the stud cavity completely and preventing thermal gaps
Custom specification with test certificates
Densities from 24K to 64K in a range of thicknesses — fire and acoustic test reports supplied on request
