Premium Lead Expansion Joint: 3m x 260mm
Premium Lead Expansion Joint: 3m x 260mm
Weld sections of this Premium Lead Expansion Joint between lengths of the box, parapet, or eaves gutters to prevent buckling and distortion due to expansion. Featuring a flexible, neoprene connector, these joints are used in situations where traditional steps and drips are not a practical option.
The expansion joint is formed from a central band of vulcanised neoprene, firmly bonded to the side wings of Code 5 lead sheet. Individual joints are cut to the required size from the supplied 3m x 260mm roll.
Lead expansion joints are usually fitted at 2-metre centres. A spacing of 1 meter is recommended on either side of outlets and corners. The guttering is overlaid on the expansion joint to provide a minimum of 25mm cover on either side. After taking care to protect the central neoprene section from damage, the expansion joint wings are lap welded to the guttering. Application of a good patination oil is recommended to prevent early oxidation. Again, it is important to ensure that the oil does not make contact with the neoprene.
This durable, watertight jointing solution carries a 10-year manufacturers warranty. Premium Lead Expansion Joints have a minimum life expectancy of 20 years if installed in compliance with the Lead Sheet Association (LSA) guidelines. These joints offer a practical alternative to reworking existing architectural details.
