30mm Rockwool RockLap Pipe Insulation (27mm outer diameter) comprises pre-formed stone wool insulation sections engineered for straightforward fitting. These segments arrive pre-slit with a factory-bonded foil facing and integral self-adhesive lap, enabling rapid installation directly onto pipework and sealing using backing tape.
Designed for heating and ventilation pipe applications across residential, commercial, and industrial settings, 30mm Rockwool RockLap Pipe Insulation delivers dependable thermal insulation performance across diverse climates and exposure scenarios, with a proven track record spanning more than 60 years.
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.
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.
• 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.
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.
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.
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.
