The Rockwool Klimafix is laminated on one side with an aluminium foil and equipped with a self-adhesive coating on the wool side. It can be glued directly to the component to be insulated. The adhesive layer is covered with a removable PE film
Self-adhesive
Melting point: > 1000°C
Hydrophobic water absorption ≤ 1 kg/m²
Heat-insulating, sound-absorbing
Equipped with an effective vapour barrier
Diffusion equivalent air layer thickness sd > 200 m
Areas of application: heat and sound insulation of air conditioning and ventilation ducts. The self-adhesive property of the Klimafix generally allows secure attachment to air conditioning and ventilation ducts without additional mechanical fixation. (In case of unfavourable width/height conditions, additional mechanical attachment may be required.)

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
