The intumescent layer will rapidly expand when exposed to heat in a fire event, closing off the air gap and preventing vertical fire spread within the external wall cavity.

• Suitable for use with either concrete or masonry internal and external substrates
• Manufactured from non-combustible rockfibre mineral wool with a reactive intumescent layer
• Provides an air gap of up to 25mm or 44mm
