Re: Re: Looking for cladding info for extension

Generally you’ll find that it’s all real pre-patinated copper being used – I’ve seen aluminium cladding being used with a copper green ral colour but that generally looks cheap and nasty.
Edgeline are the main suppliers of copper/zinc etc http://www.edgelinemetalroofing.com/
It is possible to get copper which has a coating of zinc if you wish to avoid the green pre-patinated look. Check out http://www.tecu.com/products/surfaces/tecu-zinn/pr_su_te-zi_index.php

Good luck with the extension!
