T-Pren was developed to overcome these problems by providing a waterproof expansion joint, which reduces the number of outlets and eliminates the need for steps. T-Pren is a composite material with a centre section of neoprene to provide the expansion and contraction bonded to metal on either side, which is then welded onto sections of the metal gutter.
BLM Lead T-Pren provides a quick and cost effective solution to this problem where its use as an expansion joint allows the Lead to be laid along the slope of the gutter. BLM Lead T-Pren consists of two 3m long strips of Code 5 Rolled Lead Sheet, double bonded to a neoprene middle section.
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. Where heavy foot traffic is expected in the gutter or where the T-Pren joint is visible, T-Pren Plus can be used or a cover piece of the matching metal is clipped over the neoprene section, making sure that it does not restrict the movement of the joint.
T-Pren is a composite material with a centre section of neoprene to provide the expansion and contraction bonded to aluminium on either side, which is then welded onto sections of the metal gutter. The bonding is done under strictly controlled factory conditions in.
