IMPORTANT - The below information from the manufacturer must be read and referred to your relevant authority for approval BEFORE purchase and use.

We have an indicative 30min Fire Test at a UKAS Fire Test Laboratory demonstrated 10mm loss to charring on plywood & MDF.

Our Fire Varnish BS EN Class B Test indicates that softwood did not burn significantly for the 20mins test duration and our previous Class O Part 6 Fire Propagation test indicates that protected softwood did not burn within the 10 minutes test duration.

Further in-house testing indicated that when applied at three times the Class B & Class O specification Fire Varnish intumescent added a total of 20 minutes Fire Resistance.

We assess projects requiring 30 or 60mins Fire Resistance on an individual basis, referring to the TRADA Char Rate Tables and calculated residual timber to ascertain whether we could issue a Fire Certificate for the project. A written specification should be obtained from the Technical Department for your project prior to use to ensure this system will be suitable. 

In order to enable us to issue a 30 minutes Fire Certificate in the case of softwood the surface must be able to afford the loss of 8mm depth from all surfaces exposed to a fire. For 60 minutes we assess based on 30mm loss during the fire.

For oak or similar woods the loss to take into account is 5mm for 30mins and 17mm for 60mins.

In other words, the residual timber should be adequate to in the case of:

  1. Underside of a floor to support the anticipated weight load on the floor.
  2. A timber ceiling under-drawing a floor and joists can be treated as sacrificial but should have protected the area above to 30mins
  3. A timber wall should still be able to support itself without the fire passing through to the area the other side.

Timber must be clean and thoroughly dry prior to application (maximum 18% moisture content).
