Rigid Boards

Rigid board fire protection systems can offer up to 240 minutes of fire protection. The system involves attaching rigid board insulation around metal decking, steel columns and beams which form a box. The rigid boards protect all columns and beams and are secured by using either mechanical fixings or noggins.

Rigid boards can be more expensive and slower to install but in certain conditions it provides a good alternative to other spray-applied fire-resistive materials.

Retrofitted Rigid Boards

Rigid boards can also be used in cold conditions so the building can be enclosed for heat, but allowing fire protection to spandrel steel once access has been removed. It can be retrofitted in situations where MEP – mechanical, electrical, plumbing – installations make spray applications difficult due to accessibility.
