Applications: Flooring: Sports hall renovation in Gemünden

Information in pdf format (820 KB)  
Kind of insulation: Renovation with insulation under underfloor heating
Construction: Rosel Engineering, Würzburg
Contact: ZAE Bayern, Dr. Ulrich Heinemann,
VIP product: WACKER CERAMICS, Kempten
Location: Sports hall Gemünden, Germany
Date of realization: July 2001
Funding: Bavarian State Ministry of Economics, Infrastructure, Transport and Technology

Description of the construction: The floor of the sports hall was worn down and had to be provided with an underfloor heating during the renovation. The height of the floor was limited. One part of the area was insulated with VIPs. The VIPs measured 0.5 x 1.0 m². Conventional insulation was integrated in another part of the floor. The conventional insulation (polystyrene boards) is of the same thickness as the vacuum insulation (7 cm thick), yet the U-value of the conventionally insulated area is 0.43 W/(m²K) and that of the VIP-insulated area is 0.15 W/(m²K).
