High-density Rockwool slabs with an intumescent coating on both main faces, 60mm in thickness to provide effective support and up to 4 hours fire protection. Easy to cut or resize with a sharp blade to suit any void and supplied with intumescent jointing compound for jointing and patching. It’s possible to paint over slabs without impairing its fire protective properties.

Suitable for use as a permanent fire barrier in non-load bearing walls, floors and ceilings, as well as around services and ideal for use over door frames between the door edge and ceiling. Where services and PVC pipes pass through walls or ceilings, Firoblok or EW Fire Wraps can be used for extra fire protection.

For large floor openings, it is recommended to add additional support using MESH chicken wire mesh to reinforce strength and durability and where opening is wider than 800mm use SUP metal support battern.
