Re: GBlist: environmental windows
John: Sorry, we avoid the use of aluminum at ALL POSSIBLE cost due to its
caustic effect on the environment during manufacturing.Instead we use Willguard
prepainted finish that gives a 10-12 year waranty against maintenance. We
have investigated the specific fungicides used to preserve the wood,
amounts used, outgassing characteristics and their effect on
health and have determined this is NOT to be a serious issue. If we were
to wait for the perfect world, no project would be built or nothing would
get done. This applies to every concept, feature, idea, product,
specification and person.
