These cylindrical stone wool insulation segments feature pre-slit construction for convenient installation, combined with foil facing and an integrated self-adhesive lap for enhanced performance.

Key features include

• Non-combustible construction with Euroclass A2L-s1, d0 rating
• Reinforced aluminium foil facing delivering a vapour-resistant barrier
• Self-adhesive foil lap enabling rapid installation whilst reducing reliance on additional aluminium tape
• EN 1366-3 tested for fire resistance at penetration seals, delivering up to EI 120 protection

Applications

Ideal for pipework operating between 0°C and 200°C, these sections are specifically tested for fire stopping where steel and copper pipes penetrate fire-resistant walls and floors. This certification means insulation can run continuously through the separating element, eliminating costly local 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 Pipe Sections demonstrate water-repellent properties. When deployed or stored externally, protective waterproof covering is recommended. For cold pipe insulation applications, seal joints with foil tape to prevent condensation build-up.

Service Temperature

30mm Rockwool Pipe insulation accommodates pipes operating between 0°C and 250°C. To preserve foil facing bond integrity, insulation thickness must ensure outer surface temperature remains below 80°C.

Durability

Rockwool stone wool insulation products demonstrate exceptional resilience, longevity, and dimensional stability, retaining their thickness and form indefinitely. Extensive testing confirms Rockwool insulation maintains its thermal performance and characteristics for 65+ years post-installation.
