Product Details – T-Pren Gutter Expansion Joint, Over 3000 metres of aluminium T-Pren expansion joints have been supplied for the new King Abdulaziz international airport. The new airport has been designed to accommodate 80 million passengers and will be the main gateway for pilgrims coming to perform the Haj.
T-Pren consists of two metal strips connected by a high quality neoprene expansion joint. The joint is formed on both sides of the metal during vulcanisation of the neoprene, and for lead T-Pren Plus a separate cover strip is vulcanised on top of the neoprene.
Allows for thermal expansion Double bonded for extra strength Lead T-Pren Plus protects against UV rays and foot traffic damage and provides a uniform appearance Proven reliability with over 35 years of use with no recorded failure, 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.
T-Pren Expansion Joint T-Pren Lead Expansion Joint is designed to provide a watertight joint accommodating the thermal expansion and contraction caused by extremes of weather. As in all froms of roof structure, localized water pooling may occur, but with no detriment to the life span of the gutter.
Lead T – Pren is available in 3m length rolls measuring 385mm in width. PERFORMANCE T – Pren products are designed to provide a watertight joint accommodating the thermal expansion and contraction caused by extremes of weather. As in all forms of roof structure, localized water pooling may occur, but with no detriment to the life span of the gutter. Heat, 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.
The wide curved gutter required special long lengths of T-Pren, 9 to 18m long, which were installed in pairs to provide double the expansion movement. T-Pren forms a waterproof expansion joint, which eliminates the need for the standard step detail, and results in fewer rainwater outlets.
Its two lead strips are connected by a high performance, double sided and vulcanized, EPDM synthetic rubber band. Each expansion joint has a 10 year guarantee.
