Board Fire Protection Systems
Integra Flames Fire protective boards are fitted around steel columns and beams to form a box and are usually secured by mechanical fixing into the web of the steel. Our Board fire protection systems are designed to offer up to 240 minutes fire protection. The Integra Flame systems we install protect the steel by providing a heatproof insulation. Fire board composition ranges from gypsum-based plasters or calcium silicate, through to fibres and specialist vermiculite containing materials.
The flexibility of board installation not only allows for affordable fire protection but is durable, can be resistant to water and provides acoustic performance. Depending on the type of board installation you are able to apply a variety of decorative finishes.
Intumescent Paint Systems
Intumescent paints whether water or solvent based can be applied by airless spray, roller or brush and will provide up to 120 minutes fire protection. The paint is applied as a thin film layer and is often available with a range of topcoats in different colours so that the designer can achieve their aesthetic needs while providing a suitable fire protection to the steel members.
Intumescent paints work in a fire situation by changing their composition from a decorative or non-decorative paint through chemical reaction into an intumescent layer of carbonaceous char, which forms when the coating is subjected to heat. This layer of char can be 50 times the thickness of the initial coat and is formed as the paint is heated to around 200C and above. For this reason it is critical that any secondary casings allow for the suitable expansion or 'charring' of the paint.
