Treatment

Sentrin FRI Internal timber Fire retardant treatment logo

Sentrin FRX external timber Fire retardant treatment logo

Our fire retardant treatment processes are carried out under controlled conditions in modern industrial treatment plants within our treatment centre. Each treatment process involves a high pressure impregnation of the fire retardant solution followed by kiln drying to a specific moisture content.

Fire Retardant Treatment Process

Upgrade the performance of timber in a fire

Despite timber being classed as a combustible construction material, it will perform exceptionally well compared with other materials. It can maintain its strength and integrity in a well designed structure. Large dimension timbers will develop a surface layer of char which will insulate the timber within and retard the fire development.
The surface of timber will readily ignite and spread along it’s surface. We can slow this ‘surface spread of flame’ through use of modern pressure treated fire retardants. Smoke propagation will also be reduced which is often even more important in safety critical applications such as public buildings and escape passages.

Sentrin FRI and FRX treated timber can meet the requirements of national Building Regulations where Euroclass B or C are required. These fire performance properties do not compromise critical engineering properties such as strength, durability, corrosivity and hygroscopicity.​

Treatment is carried out under controlled factory conditions. The process is ISO 9001 accredited and our productions centres hold Factory Production Control (FPC) certification and are WPA Benchmark FR approved. A computer controlled treatment process ensures the correct retention of fire retardant to achieve the required classification. Sentrin FRI & FRX are impregnated fire retardant and cannot be applied by hand, brush or spray. It provides a level of confidence in performance that may not be available with treatments applied on site or in uncontrolled conditions.
