BrookClad Fire Treated Timber Cladding

Cladding is a popular part of construction and is widely used on both domestic and industrial buildings. Timber is one of the most popular substrates for cladding and is approved for this external use under UK building regulations. Timber also offers a unique combination of practical, environmental and aesthetic advantages.

In their natural state most timber species will have a fire classification of Euro Class D-s2, dO.

Some projects or parts of projects, because of their position, design or end use may require this classification to be raised to Euro Class B All of the species offered in the BrookClad range (the exception is Red Grandis) can have their classification raised to Euro Class B with the application of additional fire-retardant treatments.

Please contact our sales team for more details on the best process for your chosen species to achieve Euro Class B.

Classification Explained B-s2,d0

B – The letter B is the main part of the classification. This letter can be taken from the following range: AL, A2, B, C, D, E, F. A1 represents the highest level of performance and F the lowest.

Materials classed Al or A2 are non-combustible. Timber can achieve Euro Class B or lower and is therefore classed as combustible, albeit to
varying degrees. The usual requirement for timber cladding where fire treatment is required is Euroclass B which can be achieved across our
species range (except Red Grands) with the fire retardant treatments offered by BrookClad.

S2 – This represents the smoke classification and can be either of the following; s1, s2, s3.
S1 represents the highest level ot pertormance and S3 the lowest.

d0 – This is the classification for flaming droplets and particles jf the timber cladding catches fire and can be either do, d1, d2. do is the highest level of performance and d2 the lowest.
