Description:

Nullifire FJ400 Intuspan is a very pliable expansion joint filler, factory applied with a revolutionary 102-times volume expansion intumescent compound. This sandwich of intumescent strip consists of a modified rubber base filled with graphite and combustion modified foam, providing a soft seal and high level of movement that is suitable for gaps up to 100 mm, with up to 2 hours fire protection with no adhesive required.

It is tolerant of very large movement and is used in areas where standard mastic joints are not suitable, such as large gaps over 35 mm, acoustic isolation joints and areas subject to regular cycles of expansion and contraction or vibration, both in compression and shear, where reliability is vital. In addition, Intuspan is particularly suitable for buildings being designed for earthquake zones or military buildings designed to withstand high ground movement shockwaves. All joints should be designed to BS 6213.

Features :

• Can accommodate regular cycles of high or low amplitude movement
• Unaffected by moisture
• Easy to install using finger pressure even in uneven gaps
• A dry system
• For vertical or horizontal wall applications
