FIRE RESISTANT BOARD THICKNESSES*
There are many different types of fire protective boards here in the UK, with different production technologies and compositions.
However, all fire resistant boards are designed to resist the heat and radiation of the fire. Fire-rated boards are also called: calcium silicate board, non-combustible board, fire-resistant plasterboard, fireproof board, fire board, fire-retardant, pink plasterboard and so on.
Fire resistant boards are manufactured by leading brands and are suitable for use in any project where additional fire proofing measures might need to be taken. In terms of fire protection boards, Promat, Kemwell, British Gypsum, Rockwool, Siniat, Vitcas and Knauf are the commonly recognised brands.
Most importantly, fireboards are available in a wide range of thicknesses. The length of time that the fireboard can retard the fire will vary depending on thickness, but ultimately, the overall construction and materials of the building is what determines overall fire rating.
Fireboard is most commonly found in 12mm and 15mm thicknesses. There are companies such as Promat that offer additional thicknesses such as 19.1mm, 25.4mm, 31.8mm, 38.1mm or 50.8mm. There is a direct correlation between the fireboard thicknesses and the amount of them that they will retard the fire. In this article, we will be reviewing all the available thicknesses of common building fireproof boards.
FIRE BOARDS THICKNESSES CORRELATION
The thicker the board the more time the fireboard will hold up and not deteriorate in the event of a fire. For instance, a 15mm fireboard will last for up to 60min, 12mm will last 45 minutes, 9mm will last one half an hour, and so on. Remember, if there is a hole in the board to allow for wiring, this will eliminate the protection that the fireboard provides. When used in a partition or ceiling, two layers of 12.5mm fire plasterboard should provide up to one hour’s fire protection. In a partition where there are two layers of fire-rated plasterboard on either side, they will provide up to two hours of fire resistance.
