Intended Use

Fire protection for bare timber sleepers, fencing, cladding and decking.

Description

Durable clear fire and flame resistant fluid for external and internal wood. Weather resistant. Water-based, non flammable formula enables safe application by untrained and inexperienced users.

How it Works

New Fire Regulations & Tests Explained

  • The new fire standard BS EN test lasts 20 mins. with airflow replaces the old BS 476 tests which lasted 10 mins and strangely restricted airflow.
  • The new standard for flamespread and heat release Class B replaces Class O.

The new BS EN tests also monitor -

  • Smoke & Gas “s” – s1 + s2 are none or very low & compliant, s3 = moderate smoke, s4 = heavy smoke.
  • Flaming Droplets or Airborne particulates – dO is none, d1 = low, d2 = moderate, d3 = high levels.
