Kemwell Tecbor® and Tecwool® F Structural Steel Protection

A fire protection board system and range of spray systems to meet the stringent requirements of the multi-storey commercial and industrial steel framed market

Kemwell Tecbor® A and B are magnesium based boards and are A1 classified as per EN standard, designed to achieve fire protection up to El 240. Kemwell Tecbor boards have been developed for a wide range of applications in today’s demanding construction industry.

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.

Several tests with Kemwell Tecbor® have been performed pursuant to standard EN 13381-4 to determine the board’s fire protection properties when applied to steel structural elements such as beams, columns or tension elements. Kemwell Tecbor® has been tested to cover a great variety of steel profiles characterised by their section factors. Likewise, it has been tested for several standard specified design temperatures.

Kemwell Tecwool® F Cementitious Spray

Kemwell Tecwool® F is a rock wool and cementitious spray specifically engineered for fire protection of all types of building structures and faces. It can be used with Kemwell Tecbor Board systems.

Kemwell Tecwool® F has been tested in laboratories and is certified by ENAC or similar to UNE, EN and ASTM or standards. Likewise, real scale tests have been performed in tunnels under particularly limiting conditions such as American UL curve.


Fire Resistance

A1 classified as per EN standard, designed to achieve fire protection up to El 240.

Moisture Resistant

Kemwell Tecbor® boards will not deteriorate when used in damp or humid conditions and will not encourage mould growth. The boards are also rot proof. Performance characteristics are not degraded by age or moisture.

Acoustic Performance and Insulation

Kemwell Tecbor® boards have high thermal insulation.

Easy Workability

Edges of boards can be squared or tapered and the boards are quick and easy to assemble.

Smooth Surface

Tecbor A and B finish can be left as a standalone or can be painted if required. Edges of boards can be squared or tapered.


Kemwell Tecbor® boards are strong and robust. System performance is unaffected by the hazards and condition of the working environment.

Vermin Resistant

Kemwell Tecbor® boards remain unaffected by rodent, termite and insect attack.
