PFC Corofil Open State Insert is a 150mm wide strip of 110kg/m3 density, non-combustible stone wool, the thickness required is dependent on the depth of the cassette panel up to 31mm deep.
PFC Corofil Open State Insert is adhered to the inner face of the cassette panel using PFC Corofil Fire Resistant Silicone Sealant and should finish flush with the face of the cassette panel facing into the void and allows the intumescent open state barrier to maintain a continuous air gap at the back of the panel without the need to notch around the panel joints.
The insert is designed for use with the PFC Corofil Open State Barrier COSB 25 (1024). The insert should fill out the depth of the cassette panel, allowing a continuous air gap to be maintained behind the cassette panel without the need for notching around the panel joints.
