LINITHERM PAL 2U Plus – The optimum thermal insulation with a breathable high-quality sarking membrane if the roof gradient is smaller than normal.

The precise nut-and-groove joint ensures an insulation surface without thermal bridges as well as quick and safe insulation even of large roof surfaces. Quickly, easily and economically to a subroof that is rainproof and/or, with additional measures, also watertight. The breathable and tear-resistant high-quality sarking membrane with TPU coating turns the insulation layer into the second aquiferous layer.

In perfect professional quality

  • Vapour barrier class A for roof pitches from 12°
  • On the upper side with tear-resistant diffusion membrane with TPU coating
  • Installed directly on rafters or boarding
