NBS Specifications for all Rolled Lead roofing, cladding, flashing and penetration details are available to download through our website. If you experience problems, please feel free to request via email or phone and an ALM representative will be happy to forward arrange. All users should be aware when using any materials that getting the specification right first time is an essential part of the design process.
Failure to form a clear specification will cause major problems for all those involved in the build potentially causing on site chaos. This can reflect badly on those involved costing the main contractor and / or the client potential loss of revenue. A well written specification can only enhance project delivery which in turn saves money for all involved.
