The best solution for the insulation of wall cavities using an ultra-thin PIR board: IKO enertherm ALU TG and IKO ALU tape.
Insensitive to moisture.
Tongue and groove (TG) connections prevent thermal bridges and moisture soaking in.
Rigid and form-stable cavity wall board.
Reflective backing.
Almost 40% thinner than mineral wool, XPS or EPS for the same R value.
Ultra-light and particularly handy format.
Very easy to install.
Fibre-free, therefore no irritation.
