Installation & Maintenance
T-Pren joints can be placed at a maximum distance apart of 6 metres. Where movement is restricted by an outlet or corner for example, an expansion joint should also be sited within 1 metre of that restriction.
However, the joint spacing depends on the metal and the gauge used. For most metals, sheets up to 6 metres can be used by correct choice of gauge, although shorter lengths might be used for ease of handling or where thinner gauges are preferred.
For lead, however, the Lead Sheet Association recommend a distance of 2 metres for Code 5 lead increasing to 3 metres for Code 8.
Jointing is easiest on flat sheets but in certain situations the metal sheets and T-Pren joints have to be pre-formed to shape before jointing. The jointing will then require extra care, particularly on the vertical sides.
The gutter lining with the T-Pren expansion joints is then formed to take up the shape of the gutter, placed into position, and cover flashings formed over the sides.
