[Strawbale] German Passiefhaus windows

[Rene Dalmeijer]

Dear all,

Whilst looking for suitable windows for my house my architect pointed  
me to this German manufacturer who on first impression makes very nice  
windows. The site is partially also in English.

The link is to a presentation giving the logic for a certain type of  
window. Click on the presentation slides and persevere to the end for a  
nice joke and all will be clear.
