Intumescent tape providing fire protection to cavities in situations where the cavity needs to be ventilated, allowing air flow in normal circumstances but closing to give a fire resistant barrier in fire conditions.
Intumescent tape providing fire protection to cavities in situations where the cavity needs to be ventilated, allowing air flow in normal circumstances but closing to give a fire resistant barrier in fire conditions. When subjected to heat, the intumescent material reacts, producing a barrier of carbonaceous char or foam and therefore stopping the fire from passing along or up the cavity.
Thermoplastic element composition containing intercalated graphite in a synthetic compound with the addition of fillers and process oils. The intumescent element may be contained within a G’Lex flexible or rigid casing.

Standards and approvals:
Can be applied to a suitable surface in line with a compartment floor or wall. Due to changing temperatures and humidity which could affect the long term performance of the self-adhesive or nature of the substrate. Therefore, the WR tape must be mechanical fixed with a steel non-combustible fixing with a 10 mm diameter head at maximum 300 mm centres. The size of tape required depends on the width of the cavity and fire resistance requirements; consult manufacturer's literature for details.
