FB770 Intudeck - Timber Floor Upgrade

Fire Stopping

Fire Rating: 90 Minutes

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.

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.
