Abstract: A wall assembly (10) comprising top and bottom caps (11) and (12) which are generally U shaped channels and these are secured to a floor (13) and a concrete slab ceiling (14) which comprises in this case the underside of a concrete floor of the next level in a multi-storey building. In these arrangements the ceiling (14) has to be arranged in relation to the wall (15) for deflection of the ceiling (14), consequentially, the track (11) is spaced from the underside surface (16) by a distance of typically 20 mm and a suitable compressible spacer arrangement (17) is located between the upper surface (18) of the track (11) and the underside surface (16). The spacer arrangement (17) may be any suitable infill and one example may be a fire rated double sided adhesive layered expandable/compressible tape or foam. This tape may be applied to the upper outer surface of the channel and its other side adhesively applied to the underside of the concrete.
