Prefabricated concrete walls offer many advantages in modern buildings in the region; from quick building progress and good thermal insulation to improve structural safety. Increasingly insulated sandwich walls with an integrated thermal insulation layer are also being built and stainless steel lattice girders are conventionally used to connect the exterior and interior panels of these walls. As an alternative to the stainless steel girders, Schoeck has introduced the new ComBAR thermal anchor made of glass fibres and a Vinyl Ester resin.
The ComBAR thermal anchor can be used to build cellars and walls of freestanding single family houses, multi-storey construction and in industrial buildings. In high-rise engineering, the use of prefabricated walls is also on the increase. Better thermal insulation U-values of the exterior walls result in a better energy balance of the building. With the Schoeck ComBAR thermal anchor the connection of the outer shell to the bearing shell of prefabricated walls, with integrated thermal insulation, can be realized virtually without thermal bridges.
The new Schoeck ComBAR thermal anchor offers a range of advantages in thermally insulated prefabricated walls. In comparison, reinforced steel has a lambda value (thermal conductivity) of 60 W/mK, stainless steel has 15 W/mK while ComBAR has 0.5 W/mK. In addition, the tensile strength of ComBAR is more than twice as high as that of steel. Along with the technical advantages, ComBAR thermal anchor offers a more affordable price in comparison to the stainless steel lattice solution.
"Thermal insulation is a key consideration in any building in the UAE and Middle East and we believe, with the ComBAR thermal anchor we have developed another product that is not only perfect for our region due to value and quality, but more viable in this economic climate as well," commented Managing Director of Schoeck Middle East Dipl.-Ing. Christoph Spitz.
Quality
The ComBAR thermal anchor from Schoeck was developed in close cooperation with numerous partners such as the Technical University of Kaiserslautern and the TU Hannover. The product is approved by the DIBt Berlin (Z-21.8-1894) for sandwich walls with internal insulation and product development was supported by the DBU (German Federal Environmental Foundation). The glass fibre reinforcement "Schoeck ComBAR" also recently received the test seal from the Institute for Construction Biology in Rosenheim (IBR). This award is given to products and production processes that achieve a special level of environmental health and sustainability.
The ComBAR thermal anchor is a ComBAR concrete reinforcing bar cut to the exact length with specially prepared bar ends. The product has already been used successfully in various large projects in the Middle East.
