Wood Roll & King Roll

BLM Wood Roll is used to provide an aesthetically pleasing expansion joint between two separate sheets of Lead. Clever design of wood roll joints can provide an exceptional focal point for a building.
Wood Roll is often used when installing Lead-lined gutters, Lead cladding, flat and pitched roofing applications. Lead Sheets are formed around the wood roll in a cloak design to provide a watertight joint without restricting their movement. Wood Roll is also used to at hip and ridge intersections.
Wood Roll & King Roll
BLM King Roll has a larger profile than Wood Roll and is used to form larger, more aesthetically pleasing, hip and ridge joints.
BLM’s Wood Roll & King Roll are manufactured using treated soft wood timber that has been impregnated with wood preservatives consisting of fungicides, insecticides and water repellent.
