KEMWELL TECBOR 15MM 2300 X 1220MM
emwell Tecbor® and Silboard® F Structural Steel Protection
Fire protection board systems designed to meet the stringent requirements of the multi-storey commercial and industrial steel framed market
Steel structures are used for building purposes worldwide. One of the main advantages is that they have great resistance per weight unit, which provides them with huge versatility and the possibility of creating complex, yet light structures.
However, the thermal conductivity of steel represents a disadvantage. Therefore, in the event of a fire, the gradual increases in temperature plus steel high heat transmission result in a substantial reduction of the structure’s bearing capacity and mechanical resistance. The resistance and elastic limit are modified above 250°C, and above roughly 500°C the drop in resistance is significant enough not to support its design capacity.
Tests with Kemwell Tecbor® and Silboard® have been performed pursuant to standard EN 13381-4 to determine the boards’ fire protection properties when applied to steel structural elements such as beams, columns or tension elements. Kemwell Tecbor® and Silboard® have been tested to cover a great variety of steel profiles characterised by their section factors. Likewise, they have been tested for several standard specified design temperatures.
Kemwell Tecbor® is an A1 classified magnesium-based board as per EN 13501-1. It is designed to achieve fire protection up to El 240. Kemwell Tecbor boards have been developed for a wide range of applications in the construction industry.
Kemwell Silboard® is a calcium silicate board with a clean white appearance and a density of approx. 550 kg/m3. It is supplied in a convenient size of 1250 x 800mm for ease of handling and is very easy to work, cut and fix. Kemwell Silboard® is suitable for internal and semi-exposed applications.
The thickness of board required to provide the desired level of fire protection is determined by reference to the steel section factor and the limiting steel temperature. The tables on page 5 of the brochure for Kemwell Tecbor® and Silboard® provide the thickness of board for up to 4 hours protection to steel factors up to A/V 250m -1 at a limiting temperature of 550°C. For other section factors and/or other limiting temperatures, please contact our technical department
