K-FLEX PU Pipe Section
£6.25
K‑FLEX PU Pipe Section is a high‑performance rigid polyurethane (PUR) insulation system designed for industrial, HVAC and process applications that require excellent thermal efficiency and long‑term dimensional stability. The closed‑cell PUR structure delivers low thermal conductivity and exceptional moisture resistance, making it suitable for demanding mechanical environments.
Key Features & Benefits
- Rigid closed‑cell PUR insulation ensures high compressive strength and stable long‑term performance.
- Low thermal conductivity: λ40°C ≈ 0.0349 W/m·K for efficient heat retention.
- Wide temperature suitability up to +110°C for heating, cooling and industrial lines.
- Euroclass E reaction to fire for standard building applications.
- Supplied in 1‑metre pre‑formed sections for rapid installation.
- Precision bore and wall thickness options ensure a secure fit across pipe diameters.
Applications
- HVAC mechanical services and hot water distribution
- Industrial process and plant piping
- Refrigeration and chilled‑water lines
- OEM equipment insulation where rigid PUR is required
