Thermoguard Wallcoat

Thermoguard Wallcoat is a smoke and flame retardant fire protection paint upgrade system that achieves EU and new British safety standards on walls and ceilings.

Intended Use – Protection and Decoration of Buildings

Thermoguard Wallcoat is an intumescent paint with smoke and flame Retardant properties for upgrading potentially dangerous ‘multi-layer’ previously painted walls & ceilings. It controls surface spread of flame and fire propagation to Class 0 & EN Class B. Total smoke control, flaming droplets and particulates to EN Class B s1 d0 (This system can also achieve 30 & 60 minutes Fire Resistance, see Thermoguard Wallcoat 30 & 60 Minute System).

Thermoguard Wallcoat Smoke and Flame Retardant Topcoat is a compatible, water-borne specialist finish that allows owners and operators of buildings to fulfil their Duty of Care for Fire Safety without having to compromise aesthetics. The system can be applied to painted plaster, Artex, plasterboard, brick and concrete.

To Specify, Simply State

To achieve BS EN Class B s1, d0, inspect and prepare in accordance with manufacturer’s instructions and apply -

*Apply 2 coats of Thermoguard Wallcoat Smoke & Flame Retardant Topcoat in Matt or Eggshell Finish in external, damp or high wear areas. 2 coats may also be required for strong/dark colours - Thermoguard Wallcoat will be provided in a suitable undercoat shade to aid topcoat opacity unless instructed otherwise.

For 30 & 60 minute protection see Thermoguard Wallcoat 30 & 60 Minute System.

Fire Testing & Certification

Tested at UKAS Fire Test Laboratory -

  • Achieved BS EN Class B s1 d0 - Highest standard

We issue a Fire Certificate upon request for each correctly specified project for Insurance, Fire and Building Authority and Client Records against proof of purchase. Certified Fire protection is guaranteed if all instructions are followed on suitable surfaces.

Flamespread & Smoke Protection

When exposed to fire, Thermoguard Wallcoat expands to create a fire protective barrier, insulating surfaces from heat and oxygen and preventing combustion. Thermoguard Wallcoat Smoke & Flame Retardant Topcoat (Matt & Eggshell) actively suppresses smoke, particles and flaming droplets.

UK Fire Safety Order 2005, Flamespread and Smoke

The Fire Safety Order 2005 requires property managers to comply with current fire standards for corridors, stairways, entrance lobbies etc. Even on non-combustible walls & ceilings, multiple layers of incompatible paints “Multi-Layer” often create the worst Class 4 - EN Class E - Surface Spread of Flame risk.

While the British Class 0 is still accepted, it will soon become defunct, as it has been superseded by the safer standard BS EN Class B s1 d0, with its more rigorous flame-spread protection and control of dangerous smoke and burnt particulates.

NEW EU/BS EN Fire Standard Explained

  • EU fire standard BS EN Class B replaces BS476 Class 0
  • In 2012 both BS476 and BS EN comply, but BS 476 is rapidly being replaced by the more severe and realistic EN test including air flow.
  • BS EN also monitors dangerous smoke. The safest class is s1
  • BS EN also measures flaming droplets & burnt particulates. The safest class is d0
  • The new safest standard for corridors, stairs etc is BS EN Class B s1 d0.
