Passive house in Belgium

For this passive house in Belgium, the focus was on a tight and accurate execution of the joints. Besides the windows in the façade, the project included roof windows in the slate mansard roof, whose installation we coordinated with the roofing work. We delivered the elements on schedule and started with the large openings, so as not to hold up the building progress. As rain was forecast for one installation day, we secured the open areas and continued in a sensible order. The joints were carefully executed, so the required airtightness was achieved and the work completed without delay.
