Applications

RockLap H&V Pipe Sections perform effectively for pipework between 0°C and 200°C. They undergo rigorous testing for fire stopping where steel and copper pipes breach fire-resistant walls and floors. This certification confirms the insulation can extend uninterrupted through the separating element, reducing installation time and labour expenses by eliminating the requirement for localised removal or refitting 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 demonstrate water-repellent properties. When positioned or kept outdoors, protective waterproof covering is advisable. For cold pipe insulation, seal joints with foil tape to guard against condensation formation.

Service Temperature

This 25mm Rockwool pipe insulation suits pipework operating from 0°C to 250°C. Appropriate insulation thickness preserves foil facing bond strength by keeping outer surface temperatures below 80°C.

Durability

Rockwool stone wool insulation delivers exceptional resilience, longevity, and dimensional consistency, preserving thickness and form indefinitely. Performance testing demonstrates Rockwool insulation sustains its thermal properties and performance characteristics for 65+ years following installation.
