Technical data: fire class: A2, operating temperature 250 °C, thermal conductivity value: 0.035 W/(m*K)
Stone wool pipe shells aluminium laminated according to EnEV 100% with self-adhesive overlap in lengths of 1 metre.
Resistant to rot and mould formation, ageing-resistant, stone wool cut from the block concentric, dimensionally accurate rock wool tube shells, slotted on one side, laminated with a tear-resistant pure aluminium foil, in AS quality according to AGI Q135
Processing instructions: pipe shells are to be secured per running metre with at least 6 windings binding wire. Before gluing the longitudinal and round joints, it must be ensured that the surface is grease-free, clean and dry. To ensure the adhesive force, the adhesive strips must be firmly pressed onto the surface, and the self-adhesive overlap must always be aligned downwards.
Highly water-repellent and odourless, easy installation thanks to double-sided adhesive tape for closing the tube shell, ideal for effective vapour barrier, pressure-resistant and dimensionally stable, universal for heat and structure-borne noise insulation
Explanation of the dimensions: e.g. 18-30 mm, for 18 mm pipe diameter x 30 mm insulation thickness
Areas of use: heating and domestic water pipes, chimney

Main highlights

Versatile application and high energy efficiency. The air conditioning mat is ideal for insulating ventilation and air conditioning ducts with rectangular or round cross-section as well as for pipes and flat technical surfaces. By reducing heat loss and avoiding condensate, it ensures stable temperatures in the medium and reduces the energy consumption of the system.
Thickness 20 mm, width 1 m, length 10 m
Moisture resistance and condensation protection. With a low short-term water absorption (WS ≤ 1.0 kg/m²) and a water vapour diffusion resistance class MV2, the climate control effectively prevents moisture ingress and condensation. This protects the installations from corrosion and building damage in the long term.
High dimensional stability and mechanical strength. Thanks to the fibres arranged vertically to the surface, the mat remains dimensionally stable even at corners, curves and bends. This design guarantees elasticity, durability and resistance to mechanical damage - ideal for complex installations.
Fire protection and temperature resistance ROCKWOOL Klimamat is non-flammable (fire class A1) and can be used at temperatures up to 250 °C (ST(+)). This means that it meets the highest requirements for preventive fire protection in technical systems.
Easy to install and flexible product lengths. Installation is quick and safe with standard fasteners - e.g. Welding pins, retaining plates, tapes or clamps (recommended: 8 pins/m²). The roll length varies depending on the thickness of the mat. This allows the product to be flexibly adapted to different project requirements.
