Applications

Rockwool RockLap H&V Pipe Sections suit pipework operating between 0°C and 200°C. They are specifically tested for fire stopping where steel and copper pipes penetrate fire-resistant walls and floors. This certification ensures continuous insulation through the separating element, reducing installation time and labour expenses by eliminating the need for local removal or replacement of the 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 demonstrate water-repellent properties. When deployed or stored in outdoor conditions, the insulation requires protection with a waterproof covering. For cold pipe insulation, seal joints with foil tape to prevent condensation formation.

Service Temperature

Rockwool 20mm Pipe insulation operates effectively for pipes between 0°C and 250°C. To preserve foil facing bond strength, insulation thickness must ensure outer surface temperature remains below 80°C.

Durability

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