Guide to Nullifire Fire Stopping

In the event of a fire in a building, and especially if the fire stop is insufficient, the fire and smoke spread very quickly through the building. Fire stopping products prevent the spread of flames, heat and smoke. The rest of the building will be safe and will allow safe evacuation and recovery.

Nullifire product range offers products, systems and solutions for all fire stopping needs for construction joints, pipe, cable and electrical penetrations on walls and floors. We work proactively with architects, specifiers, main contractors and all others involved to ensure the safety of properties and people within the UK.

Simply hover above your chosen application area, to see what products we would recommend for install and scroll down for further products information.

Our expert team are on hand to help with all your project and technical enquiries!
