Thermoguard Thermoproof Exterior Fluid
Thermoguard Thermoproof Exterior Fluid is a penetrating fire proof fluid for wood.
Please Note: Timber must be a minimum of 12mm thick for the treatment to be effective.
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
Penetrates deep into porous wood. When exposed to fire Thermoguard Thermoproof Exterior Fluid creates an inert layer within the wood’s surface which insulates the wood from fire, preventing flamespread.

Application Conditions
- Apply to dry wood (below 18% moisture) above 5°C in dry conditions prior to painting or waterproofing. Where possible wait until the wood has thoroughly dried out before fixing.

*Contact the Technical Department.
Limitations (Stained, Varnished or Painted Wood)
- Please Note: Timber must be a minimum of 12mm thick for the treatment to be effective.
- For treatment with Thermoguard Thermoproof Exterior Fluid to be effective it needs to be able to penetrate the wood.

- 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.

Questions
Question about the product
Helen Wilson on 2024-08-23 11:34:05 | Question:
Can you confirm as I would expect, that is product: 1. Meets current building standards in regard to internal lining fire spread (used on 15mm thick softwood natural bare timber internal wall cladding) in a domestic building. 2. Can be over coated in the same way as specified for the Zeroflame product, i.e. with a water based undercoat and topcoat. Thanks |
Answer from Rawlins’ Technical Team:
No, this product is for external use only. However Thermoguard Thermoproof Interior Fluid could be used as an alternative for internal application, assuming the softwood is bare, clean, dry, sound and a minimum thickness of 9mm>. This product achieves BS EN Class B s2 d0 and Class 0 fire ratings. Thermoguard haven't tested with third party paints, so advise against using anything other than the compatible Thermoguard Smoke & Flame Retardant Dualcoat. | |
Kit on 2024-08-17 10:13:45 | Question:
Hi, Pease could you advise the difference between Thermoguard and Zero Flame as a treatment for larch timber cladding on an extension? Many thanks, Kit Jones |
Answer from Rawlins’ Technical Team:
This product can be applied to bare wood that is 12mm> including cladding to achieve a BS EN Class B S2 d0 / Class O fire rating, by penetrating deep into the wood to insualte the wood from fire and to prevent against flamespread. Zeroflame Fire Retardant Treatment will achieve the same rating, can be applied to timber the same thickness, but allows overcoating if required for decorative purposes with a waterborne, non-flammabale stain, varnish or paint. | |

Hello! I am looking at fireproof coatings and in order to satisfy my building inspector, I need a certificate to show one of your coatings/impregnators have a certificate for having been tested on oak. These are the two products I'm looking at: https://www.rawlinspaints.com/home/fire-retardant-paints/timber-plasterboard/128-zeroflame-fire-retardant-treatment.html https://www.rawlinspaints.com/home/fire-retardant-paints/fabric-treatments/2298-thermoguard-thermoproof-exterior-fluid.html?search_query=thermoguard+exterior+fluid&results=1 Can you please confirm if there is a test certificate on oak available for either of these products please? The Zeroflame text specifically mentions it has been tested on oak as well as other timbers. Is it possible to get hold of a copy of that certificate please? Many thanks in advance. Adam Lay |
Answer from Rawlins’ Technical Team:
Copies of the testing on oak have now been emailed to you. | |
