What is T-Pren?
Daily and seasonal thermal cycling causes metal gutter linings to expand and contract, and if expansion joints are not provided this movement will cause the metal to crack and the gutter to leak.
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.
The bonding is done under strictly controlled factory conditions in accordance with ISO 9001 quality standards.
