Kemwell PFP Corex A1 is a non-combustible gypsum board for applications where superior fire performance and innovative solutions are required, such as structural steel protection, shaft walls, partitions, and ceiling linings.

A building with a steel frame system should withstand fire, without losing its integrity during the fire, at least for long enough to evacuate people from the building. To achieve this, the load-bearing steel columns and beams must maintain their integrity at high temperatures for long periods without losing their carrying capacity and integrity. Steel encased with Kemwell Corex A1 can maintain their load-bearing capacity for between 15 and 240 minutes.

Steel does not contribute to the spread of fire. During a fire, it fulfils its load-bearing capacity up to a certain temperature accepted in standards. The temperature at which its load-bearing capacity starts to decline is known as its ‘critical temperature’. Design in steel structures is carried out in accordance with the load-bearing capacity of each different type of steel at room temperature. A critical temperature is selected for beams and columns in accordance with the type, purpose, and the load rate of the building. This critical temperature is accepted to be 550°C in columns and 620°C in beams. When steel members are within the compartment line, for compartmentation using Kemwell Corex A1 board, please consult the Kemwell Technical department.

The core of Kemwell Corex A1 is reinforced with special additives to enhance fire resistance. Both sides of Kemwell Corex A1 are covered with a completely non-flammable fibreglass mat, meaning the board is classified as A1 non-combustible in accordance with EN 13501-1.
