Premium Glasswool Rolls / Mattress Insulation
Glasswool Rolls, also known as Glasswool Mattresses, are flexible thermal and acoustic insulation blankets made from glass fibers bonded with a high-temperature-resistant resin. They are used for HVAC ducts, roofs, tanks, and large industrial equipment to ensure superior heat control, sound absorption, and fire protection.
- Thermal Conductivity: 0.034–0.039 W/m·K
- Available in densities from 12 kg/m³ to 100 kg/m³
- Excellent acoustic absorption and vibration damping
- Fire-safe, non-combustible (Class 1, BS 476 Part 4)
- Facings: Aluminum foil, Kraft paper, or plain finish
Applications
Glasswool Rolls are widely used in industrial and commercial projects where flexible insulation is required for large areas or curved surfaces. Their roll form makes them easy to handle and install in both horizontal and vertical applications.
