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.

  • Manufactured in the UK.
  • Expected to last the lifetime of the service installation.

Standards and approvals:
