Brussels -- A passive house being built in Brussels to demonstrate how effective polyurethane insulation and other buildings products are in making a building energy efficient, has been "topped out."
The announcement comes from co-sponsor of the project ISOPA, the European trade association for producers of diisocyanates and polyols - the main building blocks of polyurethanes.
The roof was installed by ISOPA's partner construction company Bostoen on 25 Nov, and a video onYouTube shows this and other clips.
The Polyurethanes Passive House was launched on 1 Sept 2011 in Brussels, near the institutions of the European Union, to document the construction of a passive house from floor to ceiling.
It uses polyurethane materials wherever possible, providing a living example of the environmental and economic benefits of the most modern construction standards, the passive house standard.
For homeowners, students, architects and builders, the project is shows how to build "a house that has the smallest environmental impact while saving its owners money," says ISOPA.
Belgian company specialises in the construction of affordable passive buildings and the installation of solar panels.
