Lead T-Pren 3M x 385mm

A large number of buildings in the UK contain Lead-lined parapet or box gutters. The correct design for a Lead-lined gutter incorporates drips and falls or “steps”. However, in many buildings the gutter design may prevent the use of the correct drip detail or the necessary restructuring of the gutter, potentially leading to the over-sizing of the Lead bays that make up the gutter lining. 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 guttering.

• Always use the recommended underlay for the substrate
• Ensure that Lead T-Pren joints are fitted no further than 1 metre from either side of an apex
• A double weld should be sufficient when lap welding to Code 6
• Lead T-Pren joints should be fixed at maximum 2m intervals
• Standard Lead T-Pren: 3m long x 385mm wide
