Knauf Insulation

Industrial roller RL 220, Knauf

Art. no.: 19059652

Power-teK RL220 is a light mineral wool mat that is designed for installation on e.g. accumulator tanks and other forms of cisterns. The mat is very flexible and easy to install and allows for insulation thicknesses of up to 300mm per layer. Which gives fewer layers of insulation with possible time savings as a result. The carpet is delivered in compressed rolls, which makes transport and handling of the material at the assembly site efficient.
Knauf mineral wool products are manufactured with ECOSE® Technology, a binder that has no added formaldehyde and is based on renewable bio-based ingredients instead of petroleum-based chemicals. The technology makes the products extra pleasant to handle which makes them extra installation friendly (they are soft, but flexible and give a pleasant feeling). All technical characteristics maintain a competitive level or higher. Handling, installation and fastening correspond to current market standards. ECOSE® Technology, binder without added formaldehyde provides an odorless, pleasant mineral wool with excellent fiber elasticity for a perfect fit on all types of pipes, ducts and containers. Thermal conductivity (λ value) 0.042 at 50°C.
