  • Based on renewable materials and is environmentally sustainable, contributing to green building.
  • Reduces embodied energy.
  • The intumescent material is not affected by moisture.
  • Air and water permeability tested.
  • High speed, easy installation with minimal waste.
  • Single component.
  • No Volatile Organic Compounds (VOCs).
  • No curing time is required.
  • Low maintenance system with long life.
  • Soft to touch, odourless and easy to cut.
  • Free of halogens, asbestos, fibres and silica, and is non-toxic.
  • High speed installation.
  • Can be used in both internal and external applications.
  • Life expectancy of over 25 years.
  • CE marked.


Suitable for use in irregular applications, including:

  • Historical building upgrades.
  • Voids up to 450 mm wide.
  • Rigid floors of 150 mm minimum thickness.

Conforms to/ approved by:

  • EN 1366-4.
  • EN 10140.

Brackets should be positioned at 300 mm and 700 mm, and must be fixed to the rigid structure using no combustible fixings. A minimum of two brackets should be used per 1200 mm length.
