Application

Partial fill insulation for masonry cavity walls.

Description

ROCKWOOL® High Performance Partial Fill Cavity Slabs are a robust and durable solution for the thermal insulation of external masonry cavity walls. High Performance Partial Fill slabs further maximize energy efficiency by knitting together when tightly jointed in order to eliminate performance sapping gaps. The slabs are Euroclass A1 non-combustible and water repellent. Made from abundant, renewable volcanic rock, which is recyclable.


Features and benefits:

  • Euroclass A1 non-combustible.
  • Dual-density slabs (applicable to >90 mm-thick slabs only) - absorb irregularities on the inner leaf and provide a robust outer surface.
  • Water repellent - prevents water transmission from outer to inner leaf.
  • Superior fit against blockwork.
  • Dimensionally stable and robust - preventing slumping and sagging.
  • CE marked to BS EN 13162:2012+A1:2015.
  • BBA certified (certificate number 93/2884).
