Martin Holladay asks: " Are you implying that in Germany you are not allowed to reuse EPS from a demolition site?" I'm saying that ozone depleting substances are not allowed to be re-used or recycled. That is world standard. If these things turn up 'for cheap' or 'for free' then because some cowboy is involved. Some flame retardents used in the past for EPS are banned now as well (bromium), not only CFCHs. These things should be known to "green builders" and their architects. Mind the cowboys in the trade.

For the German window installation details see " Leitfaden zur Montage von Fenstern und Tueren " ISBN 978-86950-082-9 The manufacturer will be able to provide coppied details for the particular project.

Dan Kolbert asks: " They've already been made. What is gained by throwing them away instead of reusing them?" These materials are handled as hazardous waste. And are accordingly made safe, the foam's HCFCs extracted and chemically broken up. And the Flour turned into tooth paste, for example. By no way these wastes are to be thrown away, they have to be handled and processed by licensed waste handlers. -------------- Martin Holladay writes: " EPS is not manufactured with any ozone-depleting blowing agents like CFCs (chlorofluorocarbons) or HCFCs (hydrochlorofluorocarbons). " Emphasize "IS" and you're correct. But in the past there was allowed ANY blowing/foaming agent, including CFCs. And we are talking about recycling of old material. Which might have been recycled before, undocumented .... Quoting from http://www.pharosproject.net/blog/detail/id/58 "Avoiding damage to the ozone layer, however, has come at a cost. Some of these blowing agents, such as the HFC-134A used in Styrofoam are even more potent global warming gases than the CFCs they replaced, leading to serious questions about the basic efficacy of this insulation to fight global warming, an issue that warrants further attention. " There was absolute no control in the past (prior to the year 2000) what sort of foaming agent was used in the manufacturing of EPS. About flame retardants at page 25 here: http://www.unep.org/yearbook/2010/PDF/year_book_2010.pdf Some are banned already, 2 are still allowed to be recycled until 2030 according to this document. Put them into the house and you have a 'dead asset' after 2030. Like using asbestos fibres for thermal insulation in the 1970s. Such a rcycling/reuse is blindfolded , will costs life and health and not save a single Watt of energy because of the high energy costs associated with it. There is a very good reason why these things are banned: the usage of these materials is anti-social. Mind the greenhorns.

Thanks , Martin, is there other than advertising material to confirm this?

Better: a proper house, safe and bankable. Instead of a WW trench.

As previous posters suggested: the existing system seems to be absurd. What is the plumber saying about it? Circulation pumps are installed to avoid waiting times, b.t.w..

strange picture @David Mailand: A bulldozer is a certified tool, fully insured with a roll bar. Professional builders wear hard hats, fully insured - under the roll bar... .............................................. There are data/picture banks for professionals, Martin. For very little money.
