Product Description:
DLM Wallace Lead Sheet & Acrylead consist of virgin lead of at least 99.8% purity, machine cast in to sheet form of various dimension and thickness. Acrylead has a factory baked acrylic primer coating which inhibits the contact of water with the lead and its oxides, greatly reducing lead run-off which can cause staining on surrounding roof materials such as tiles.

Scope of use:
Lead Sheet & Acrylead are used as a flexible weatherproof flashing to drain or deflect water back outside roof
and wall cladding systems. They are commonly used for flashing concrete, clay and slate tile roofs, for buildings described in Table 1 of NZS 3604:2011, and NASH Standard Part 2: May 2019- 1.3.1.
