ISOPA represents the manufacturers of aromatic diisocyanates and polyols, the main raw materials for polyurethanes in Europe. The Polyurethane Passive House project was undertaken by ISOPA with the help of Bostoen, to show how it is possible to build a passive house using polyurethane materials from floor to ceiling. This website will track the progress of building a passive house, taking an interactive approach to showing how a polyurethanes passive house is built from Day 1 to completion. We produced a series of construction in action videos at various stages of the project.
