Nullifire FR230 Intucompound Fire Mortar


FR230 Intucompound Fire Mortar

FR230 Intucompound is a gypsum based mortar used to reinstate the fire resistance performance of floor & wall constructions where they have been breached with apertures for the penetration of single or multiple services. FR230 provides a safe working platform for loads up to 2.5 kN/m² when installed in full accordance to our recommendations.


FR230 is used to stop the spread of fire and smoke around services that pass through compartment walls and floors, whilst providing a load bearing capability (refer to application instructions). The system also provides thermal, acoustic and air sealing performance. FR230 is suitable for the following service penetrations: single and bunched cables, cable trays/ladders/baskets, non-combustible pipes. Also suitable for cable trunking, combustible pipes, insulated non-combustible pipes, in conjunction with a suitable Nullifire closer device (for example FP302 Intustrap or FS709 HP). May also be used around dampers & ventilation ducts (consult manufacturer). Typical areas of use include health and leisure facilities, schools, universities, hotels, commercial, retail and industrial buildings.

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

Rigid floors must have a minimum thickness of 150 mm (walls 100 mm) and comprise aerated concrete or concrete with a minimum density of 650 kg/m³. The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance and be suitable for the imposed load of the FR230. FR230 may be used to seal apertures in the separating element up to 1100 mm x 1100 mm in a floor or wall (without additionnal reinforcement requirements). FR230 may be used to seal apertures above 1.21m² with additional reinforcement (consult CPG UK Technical Service). Re-bar may not be used within a FR230 fire seal as a load benefit. FR230 can be coated with any masonry paint to achieve a required colour. If the floor slab is less than 150 mm thick, FI140 Shutter Slab should be face fixed to the underside using suitable anchors (alternative products may be used for shuttering, however if your chosen shutter is combustible, it must be removed after 50 hours). FR230 should never be cast across a movement joint nor supported by a non-load bearing element. Do not try to extend the working time by adding additional water. Always mix in clean buckets. Using dirty buckets with mortar residue from previous mixes can reduce working time or prevent the product from achieving a correct chemical cure and bond.

Safety data sheet must be read and understood before use.
