Description

Range of intumescent air transfer grilles that are suitable for use in door sets and compartment walls for up to 60 minutes' fire resistance.

Constructed from 0.65 mm-thick Zintec mild steel containing high performance graphite-based intumescent material which reacts under the influence of heat to form a carbonaceous char, which provides an effective insulation plug thus preventing smoke and fire passing through to the adjoining compartment.

Features and benefits:

  • Modular, robust construction.
  • Easy to install and maintenance free.
  • Manufactured in the UK.
  • Expected to last the lifetime of the service installation.

Standards and approvals:

Tested by Warrington Fire Research Centre according to BS 476 Parts 20 & 22: 1987. Tests show that a 600 x 600 mm grille can provide fire resistance of up to 60 minutes.

Application:

Specifically designed for the use of fire resisting door sets for 30 minutes and 60 minutes. See manufacturer's literature for detailed installation instructions.
