To achieve 30 & 60mins + EN Class B s1 d0 and BS Class 1/0 minimum thicknesses apply of which approval must be sought before purchase.
IMPORTANT - The below information from the manufacturer must be read and referred to your relevant authority for approval BEFORE purchase and use.
Half Hour and 1 Hour Resistance To Wood
In line with good common practice, we recommend that approval be sought for the use of our system, outlining our justification for the issuing of the Fire Certificate prior to the product’s use.
Authorities generally accept our Fire Test evidence (copies available upon request) as justification for the provision of One Hour Fire Resistance in cases such as this for up to 1 Hour Fire Resistance, depending upon the thickness of board in question.
We hold independent Fire Tests for Thermoguard Timbercoat to provide One Hour Fire Resistance to a mock-up of a ceiling comprising softwood timber boards on softwood joists, with the boards abutting one another and joined by metal tongues set into the abutting edges of the boards. Whilst the amount of residual undamaged timber was clearly adequate to have withstood office or accommodation design loads, the floor tested in the Fire Test did not have weight imparted to it, as we sought data to work from the test for sites with greatly differing make-ups.
The floor tested achieved One Hour Fire Resistance to BS 476 Part 22, with approximately 7mm of timber joist and board surfaces destroyed to charring during the test. Charring was greater up the open joints between floorboards, reaching 12mm, as one would expect being merely butt-jointed rather than tongue and groove jointed. Provided the calculated residual structure is adequate, we also issue Certification to BS 476 Part 21 to 30 or 60min Fire Resistance. The normal char factor of unprotected softwood for 60 minutes is approx 50mm, thus additional Fire Resistance provided by our Intumescent Paint was approximately 30 minutes.
A Fire Resistance test for 30mins was carried out at Warrington Fire Research Centre in January 2016 to 25mm softwood and 25mm MDF. Uncoated boards burnt through completely during the test.
- Application at 300 microns wet (12m² per 5kg) resulted in loss to char of 7mm on softwood and 5mm on MDF
- Application at 500 microns wet (8m² per 5kg) resulted in loss to char of 3mm on softwood and 2mm on MDF
Thermoguard Timbercoat was filmed by Chanel 5 for documentary “Megastructures – Building from Distaster” which recorded in simultaneous parallel test to 18mm softwood that at 6mins uncoated board burnt through, while boards protected with Timbercoat @ 600 microns / 7m² per 5kg lost only 3mm to char at 45mins, with the protected board retaining insulation so that it was safe to put a hand on the reverse face while the burner continued on the front face.
Minimum timber board thicknesses;
- 30min protection - Board must be a minimum of 10mm thick
- 60min protection - Board must be a minimum of 20mm thick
Applications to achieve 30 minute protection can in certain instances achieve a 'reduced' specification if timber is significantly thicker than 10mm, please contact us for a bespoke specification/quotation.

Do you offer a product with a CLEAR finish that will provide 30 minute fire protection to new oak joists? Thanks.
We would suggest Thermoguard Fire Varnish 30 & 60 Minute System may be suitable for your requirements.

Would Thermoguard be suitable for coating the floorboards and Oak rafters in a cellar to produce 60 minutes protection to meet Fire Officer requirements for the charity shop above (no cooking facilities). Alan Julier
To be able to advise on this we would need to know the thickness of the floorboards (also whether they are butt jointed, T&G, etc.) and the dimensions of the rafters (width x depth). Also helpful would be how many square metres of floorboards there were to protect and how many rafters were to be protected and the length of each.

Can this product be applied to wood that has already been painted? Our under the stairs cupboard that contains our electric meters has old gloss paint on the wood and stripping all that back wood be a very difficult if not impossible job as old gloss paint isin the joints. If this product is not suitable for planting over old paint can you recommend a product that you do have for this. Many thanks
Yes the Thermoguard Timbercoat system can be applied over existing paints as long as they are sound, well adhered and are not previous fire protection products. See further information below;

Question: Hello can you tell me, is your Themoguard Timbercoat suitable to use on exposed wooden joists and floor boards in a basement kitchen ? Regards: L Morris
We would need the dimensions of the joists, thickness and surface area of the floor boards and the level of fire protection you require (i.e. BS Class 1, Class 0, 30min, 60min, etc.) to enable us to produce a specification for you to confirm suitability prior to purchase and use.
