Doors and windows are obviously essential in any building, including those constructed using sandwich panels. The windows and doors developed for this purpose can be customised in a variety of ways; for example, the customer is free to choose the colour, coating and thickness of the doors.
In buildings where insulation plays an important role, a door should contribute to this as much as possible. Even window frames can be adapted to the core thickness of a sandwich panel.
A great light solution for insulated roofing sheets is the Velux rooflight. This Velux combination set consists of a finishing frame that perfectly matches the roofing panels, an inner frame and, of course, the window.
