Description

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.

Features and benefits:

  • Graphite based intumescent material.
  • Allows cavity to be ventilated and allow air flow in normal circumstances.
  • Fire performance is not affected by the presence of atmospheric moisture or condensation.
  • Available in two sizes.
  • Quick and easy to install - supplied with self-adhesive tape for ease of fixing, subject to satisfactory substrate.
  • Manufactured in the UK.
  • Expected to last the lifetime of the service installation.

Standards and approvals:

  • Tested to BS 476: Part 20: 1987.
  • Up to two hours and 30 minutes fire rating.

Application/ installation:

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.
