Applications

These pipe sections perform reliably for pipework operating between 0°C and 200°C. They are specifically tested for providing fire stopping where steel and copper pipes penetrate fire-resistant walls and floors. This testing ensures continuous insulation through the separating element, reducing installation time and labour expenses by avoiding local removal or replacement of pipe insulation.

Fire performance

• Euroclass A2L -s1,d0. • Tested to EN 1366-3, the harmonised European standard for the fire resistance of penetration seals. • Provide up to 120 minutes* fire resistance integrity and insulation.

Water Resistance

Rockwool RockLap H&V Pipe Sections offer water-repellent properties. When used or stored outdoors, protection with a waterproof covering is recommended. For cold pipe insulation, seal joints with foil tape to prevent condensation buildup.

Service Temperature

This 25mm Rockwool Pipe insulation suits pipes operating between 0°C and 250°C. To preserve foil facing bond strength, insulation thickness must ensure the outer surface temperature remains below 80°C.

Durability

Rockwool stone wool insulation products deliver exceptional resilience, durability, and dimensional stability, preserving thickness and form throughout their lifespan. Testing confirms Rockwool insulation maintains its thermal performance and characteristics for over 65 years following installation.
