LINITHERM PGV T

Permeable over-rafter system for improved insulation with existing vapour barrier and between-rafter insulation

Reliable insulation ...
  • Vapour barrier class A for roof pitches from 20°
  • LINITHERM PGV T can be combined with any other insulating material between the rafters
  • Greater freedom when planning a new building

... in perfect professional quality ...
  • Tear-resistant diffusion membrane
  • With printed grid for fast installation
  • Permeable mineral fleece layer on both sides
  • Full-surface, seamless insulation
  • Installed directly on rafters or boarding
  • Suitable as a temporary roof covering

... for PUR(E) energy saving
  • Protection from heat in summer
  • Thermal protection in winter
  • Insulating core made of PUR/PIR rigid foam
  • Consistently high insulation values (TCL 025 / 026)
  • Maximum insulation with minimum panel thickness
  • Positive building biology: PUR/PIR rigid foam is free of CFC, HCFC, formaldehyde, and fibres
  • Positive life-cycle assessment
