Glass Fiber Insulation
Glasswool Pipe Section / Self-Seal Cover (Foil)
Main applications
Cylindrical glasswool matched to your pipe size
- installed immediately
- insulated completely
Key Features
🔧
Cylindrical, sized to pipe OD
Two-piece half-shell construction — fitted over the pipe and secured immediately, with no welding, maximising installation speed
🌡️
Excellent thermal efficiency
Low-conductivity glasswool in cylinder form — suppressing both heat loss and condensation on chilled and hot water lines
✨
Foil self-seal cover option
The aluminum foil self-seal type finishes without separate cladding, saving installation labour
🔥
Non-combustible material
Inorganic glass fiber — Class 1 non-combustible, safe in hot and fire-exposed environments
📐
Full size range
Covers pipe sizes from 15A to over 600A — thickness and density available to order
