What is FR board?

2025-08-25

FR Board is designed to prevent the spread of fire and smoke through openings in fire rated walls and floors where openings are formed to allow the installation of multiple building services. FR Board will also maintain the acoustic designed performance in fire rated walls and floors.

Nylon and polyester are both popular materials used in FR clothing due to these high melting points and low thermal conductivity. Manufacturers often treat these synthetic fibers with a fire-resistant chemical for additional protection.

Importantly, some engineering plastics, but more so Industrial insulation plastics, can be classified as 'FR'. Or, fire retardant plastic materials and, flame resistant plastic. Certainly, no plastic exists that is completely a 'fireproof plastic material'.

Flame Retardant (FR) plastics are essential to devices we use every day, providing a valuable tool in fire prevention. In order for fire to occur, three basic elements must exist: fuel, heat, and oxygen. The science of flame retardance uses chemical reactions to moderate one or more of these fire elements.
