Unifold® Clip Joint System Unifold® Clip Joint System is a patented system used to allow the installation of Unifold® in difficult access situations where the gutter is narrow, small or where sheet overhang is excessive and prevents access to the extremes of the Unifold® or where drill and rivet penetrations are un-desirable. Patent Number 2376481.


Installation progression of a typical clip joint


Outlets are provided to suit any existing configuration in either membrane only, as outlet liners, or metal/membrane for additional or replacement outlets Nb: When extra outlets are required all unifold® outlet types can be provided with an easily removable blanking plate to allow the outlet to be fitted but only to become operational when pipework serving the outlet has been installed.


Corners are factory fabricated units, provided in two parts, split along the centre-line of the Unifold®


Expansion and Contraction joint


Lining systems need expansion and contraction joints in certain circumstances to ensure that outlet liners remain in position and fabrications are not stressed by thermal or structural movement and to enable the system to move in complete conjunction with the existing gutter beneath. It is an integral part of the system and is manufactured within an individual length of Unifold®.


It is used to coincide with building expansion joints, when Unifold® installations exceed 100 metres or when Unifold® must be induced to move with the existing gutter in installations where the thermal movement of the existing gutter is greater than Unifold®. eg. Aluminium and G.R.P. gutters. The provision of an expansion joint creates a small raise in the sole of Unifold® and therefore should be positioned between outlets or discharge points.

gutter sole to ensure ease of site installation and sealing. The gutter profile is factory sealed.
