Kind of insulation: Terrace/ceiling renovation with vacuum insulation
Construction: BaumitBayosan GmbH &Co. KG (Bad Hindelang) and Prill & Schurr Architects
Contact: Rudolf Schäfer,
VIP product: WACKER CERAMICS, Kempten
Location: Allgäu Energy and Environment Centre (eza! house), Kempten
Date of realization: 2001
Funding: Bavarian State Ministry of Economics, Infrastructure, Transport and Technology

Description of the construction: The cellar ceiling was insulated from the outside (part of the cellar is beneath the outside entrance area). 3 cm thick polystyrene-encased VIPs were installed underneath the paving, therefore insulating the ceiling below. The encased elements measured 50 cm x 50 cm x 3 cm, whereby the VIPs inside measured 48 cm x 48 cm x 1 cm. The advantage of the encased VIPs is that they are easy to handle, but when fully encased, the VIPs can no longer be visually checked for flaws. The polystyrene edging also increases the U-value - 0.28 W/(m²K) in the centre of the element and 0.35 W/(m²K) for the total area.
