    Fire Rating

    SilaCote has a B fire rating which is much higher than most other liquid coatings. Now, more than ever, specifiers require reassurance and peace of mind when specifying building products for their construction projects with higher fire ratings.

    Fire testing is standardised through the use of EN 13501-1: Fire classification of construction products and building elements. The most widely recognised standards are the German (DIN 4102) and French (NF P 92 503-507 (M1)). The European classifications based on the EN13501-1 standard break down into codes.

    Products that have been given a fire rating on the European Classification will look like the following: A2, s1,d1. This classification shows the properties of a product based on 3 criteria.

    There are 7 reaction to fire classifications levels available:
    The reaction to fire classification determines how much (if any) a material contributes to the spread of flame:

    A1, A2 = Non Combustible Materials.

    B, C, D = Ranges from very limited to medium contribution to fire.

    E, F = High contribution to fire.

    The ‘s’ part relates to total smoke propagation, during the first ten minutes of exposure.
    These determine a ‘smoke’ index:
    S1 = a little or no smoke

    S2 = quite a lot of smoke

    S3 = substantial smoke

    The ‘d’ part relates to ‘flaming droplets and particles’ during the first 10 minutes of exposure.
    The index is:
    D0 = none

    D1 = some

    D2 = quite a lotRanges from very limited to medium contribution to fire.
