Applications

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 testing ensures continuous insulation through the separating element, reducing installation time and labour expenses by eliminating localised removal or replacement requirements.

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

30mm Rockwool RockLap H&V Pipe Sections are water repellent. However, when used or stored outdoors, the insulation should be protected with a waterproof covering. For cold pipe insulation, joints should be sealed with foil tape to prevent condensation.

Service Temperature

30mm Rockwool Pipe insulation is suitable for insulating pipes operating between 0°C and 250°C. To maintain the bond strength of the foil facing, the insulation thickness should ensure that the outer surface temperature does not exceed 80°C.

Durability

Rockwool stone wool insulation products are highly resilient, durable, and dimensionally stable, maintaining their thickness and shape over time. Tests have shown that Rockwool insulation retains its insulating properties and characteristics for over 65 years after initial installation.
