Code 4 lead flashing soakers

Code 4 lead flashing is often the first choice for soakers. This is because it’s the maximum allowed thickness that soakers can be.

The thing is:

Using a thicker lead code can mean that tiles or slates don’t lay properly, due to the materials beneath them. So, all soakers must be supported properly to serve their function.

Other applications of Code 4 lead

As previously mentioned, Code 4 lead can be used for many roofing applications. At 1.8mm thick, it serves the minimum required thickness for all flashings. This includes window flashings, apron and cover flashings, chimney flashings, step flashings and more. You can even use it for vertical cladding, too.

Code 4 lead is known for its ease of moulding, durability and adaptability to various weather conditions, so it’s an ideal choice for projects in the United Kingdom.

Additionally, Code 4 lead is manufactured entirely from recycled materials to BS EN 12588:2006 standard, making it an environmentally friendly solution which has been a trusted construction material for centuries.
