FB770 Intudeck is a rock mineral fibre
board coated on one side with a smoke
and fire resistant sealant.
Light weight and quick to install, FB770
can be cut to suit on site and fitted using
compression and FS702 Intumastic
bonding between joists.

Fire Rating: 90 Minutes

Usage/purpose

Ideal where decorative ceilings cannot be disturbed or accessed due to lower floor occupancy. FB770 may be used to upgrade the compartment capability to 90 minutes fire integrity and insulation (EI 90) whilst maintaining the load capability of the floor. FB770 is often used above ornate lathe and plaster ceilings within heritage homes but is also suitable for use in small units such as flats above shopping
facilities or multi-occupancy building conversions. In conjunction with other Nullifire products, FB770 is service receiving and can accommodate both combustible and non-combustible services. Please
consult CPG UK Technical Service for further details.

Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest
ocuments are downloaded prior to every project commencement.
