LINITHERM PAL 2UM – The above-rafter thermal insulation system with increased noise insulation for more comfort in living spaces under the roof

LINITHERM PAL 2UM is twice the protection in just one workstep: it combines the excellent thermal insulation of rigid PU foam with the highly efficient noise insulation of mineral fibre. This creates a noise-protected, pleasant living atmosphere, reducing heating costs and protecting the environment.

In perfect professional quality

  • Vapour barrier class A for roof pitches from 20°
  • Soundproofing value Rw = 44 dB
  • For installation on boarding
  • With integral vapour barrier
  • Tear-resistant diffusion membrane
  • Suitable as a temporary roof covering

For PUR(E) energy saving

  • Insulating core made of PU rigid foam
  • λD 0.022 W/(mK)
  • Positive building biology

Over-rafter insulation - LINITHERM PAL 2UM

Insulation core PU rigid foam acc. to EN 13165, fire behavior class E acc. to EN 13501-1, coated with aluminum film on both sides
Facing Upper side covered with a diffusible, tear-resistant, non-slip sarking membrane, approx. 8 cm overlap lenghtwise and transverse, plus integrated factory-made sealing band, lower side with a noise protection board, 40 mm to improve sound insulation characteristics
