Intuspan

A very pliable joint filler factory applied with an intumescent compound which expands up to 102 times its volume. A sandwich of intumescent strip, consisting of a modified rubber base filled with graphite and combustion modified foam, provides a high level of movement suitable for gaps up to 100 mm and provides two hours protection with no adhesive required.

Features and benefits:

• Tested to BS EN 1366-4 and BS 476-22.

• Fully tested for up to 120 minutes' integrity and insulation.

• 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.

Applications:

Intuspan is used to provide a soft seal to movement joints from 25–100 mm wide, whilst offering up to two hours' fire protection. 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.
