+44 (0)1634 835290 Website

Application

The cement skin enables the thermal and acoustic insulation board to be coated directly with: -

  • Render on external walls.
  • Plaster on internal walls and ceilings.
  • Tiling on internal walls subject to high temperatures.

Being a Class A1 rated product, the boards can be used externally above 11 m and when in close proximity to adjoining properties.

Description

A rigid thermal and acoustic insulation slab comprising a core of mineral wool encased within a reinforced cement skin. The cement skin enables these slabs to be thinner and more stable than uncoated mineral wool.


Features and benefits:

  • Certified as A1 non-combustible.
  • Acoustic insulation.
  • Thermal insulation.
  • Lightweight.
  • Weatherproof.
  • Render or plaster.
  • External or internal.
