Description

IZOTERM mineral wool insulation slabs. Non-combustible, vapour-permeable, good at absorbing noise and resistant to rot. P-75 slabs (75 kg/m³) are used where the insulation carries no load: loft floors, floors between joists, pitched roofs. Denser P-125 (125 kg/m³) is for frame walls, partitions and vertical structures where the slab must hold its shape.

Key benefits

  • Non-combustible material
  • Thermal and acoustic insulation
  • Vapour-permeable — the structure can breathe
  • 75 and 125 kg/m³ densities
