Sentrin FRI
Sentrin FRI fire retardant treated timber has been pressure impregnated with a humidity resistant, high temperature fire retardant formulation (Osmose FirePRO). It has been processed under ISO9001 controlled factory conditions to provide confidence in performance and long lasting protection without further maintenance. Treated timber can meet the requirements of national Building Regulations where Euroclass B or C are required and will significantly reduce the spread of fire, heat generation and smoke generation. These fire performance properties do not compromise critical engineering properties such as strength, durability, corrosivity and hygroscopicity.
Sentrin FRI treated wood products have been tested to BS EN 13501-1:2002; Fire classification of construction products and building elements. These ‘reaction to fire tests’ are used to generate classifications of flammability which are commonly specified in building regulations. To specify the correct level of protection the following information is required:
1. Timber species or plywood type and dimensions.
2. Euroclass required (C or B).
3. End use application (must be weather protected).
Sentrin FRI treated wood products meet the requirements of HR (humidity resistant) and DI (dry internal) specifications. It is approved by London Underground for use in construction and maintenance projects. Certificate ID 1327 Osmose FirePRO.
Treatment Process
Treatment is carried out in high pressure autoclaves to penetrate fire retardant into the timber to achive the required classification. Timber is loaded into the treatment vessel and the door sealed. A vacuum is then created inside the to remove air from the timber. The vessel is flooded with fire retardant solution and high pressure applied to penetrate into the timber.
After the solution is removed a final vacuum is created to remove excess liquid. The liquid is returned to storage and there is no waste generated from the process. The freshly treated timber is then held undercover until it is drip dry before being kiln dried to its desired moisture content. Process times vary with the treatment specification but are typically between 90 and 240 minutes.
