Intudeck - Timber Floor Upgrade
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.
Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest
ocuments are downloaded prior to every project commencement.
FB770 has been tested in a loaded
robust floor detail, using a joist size
of 196 x 45 mm. This joist size may be
increased without assessment, but
not reduced. For joist reduction, a
structural engineer will be required.
• FB770 has also been tested in a nonloaded robust floor detail, using a joist
size of 160 x 48 mm. This joist size may
be increased without assessment,
but not reduced. For joist reduction, a
structural engineer will be required.
• This product should not be in direct
contact with CPVC pipes; FS719 HP
Blue for CPVC should be used on the
full depth of the FB770 Intudeck, to the
correct annular space.
• If used around Pegler X-Press Carbon
Steel pipes, the pipe manufacturer
should be consulted and their
recommendations followed.
Safety data sheet must be read and
understood before use.
