Product Description

Polyurethane Foam Pipe Shell Hot Water District Heating Insulation for HVAC Pipeline Network

Product Description

Polyurethane Foam Pipe Shell is a rigid insulation section moulded from PUR and PIR closed-cell foam, available in two-half and co-jacketed forms to wrap hot water and heating pipes.

The foam keeps a thermal conductivity of about 0.024 W/(m·K) for PUR (about 0.022 W/(m·K) for PIR), sharply reducing heat loss along district heating and HVAC networks.

A closed-cell content of 93% (PUR) to 95% (PIR) or more resists water and vapour, so buried or surface pipes keep a stable insulation value even in damp ground.

Supplied as two half-shells with a lap joint, the shell clips around the pipe for fast installation and forms a tight, gap-free layer along straight runs, bends and fittings.

A core density of 40–60 kg/m³ and an oxygen index from 26% (PUR) to 30% (PIR) give good mechanical strength and improved fire reaction; flame-retardant grades reach B2 or B1.

Typical applications include hot water pipes, district heating mains, HVAC lines, solar hot water systems and process piping where heat loss and condensation must be controlled.

Product Features

Excellent Thermal Insulation – About 0.024 W/(m·K) reduces heat loss along heating and HVAC runs.

Closed-Cell Waterproof – 93% (PUR) to 95% (PIR) closed cells resist water and vapour.

Fire Retardant B1 Grade – Oxygen index 26% (PUR) to 30% (PIR); flame-retardant grades reach B1.

Two-Half Lap Joint – Half-shells with lap joint fit quickly around pipes and fittings.

PUR / PIR Available – PUR for general heating lines, PIR for higher heat and fire duty.
