Description of the construction: The cellar was to be used as a classroom subsequent to renovation. The height of insulation was limited. To achieve acceptable floor insulation values, the flooring inside was realized with a sandwich design. The 2 cm thick VIPs were laid between softboard and polystyrene. A layer of OSB was installed on top. This floor set-up achieves a U-value of 0.17 W/(m²K).
