Premium Lead Expansion Joints
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 roll.
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.

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.
