BASF Showcases High Performance Insulation Solutions at BAU 2019
SLENTEX®: Non-combustible and flexible insulation mat
SLENTITE®: Slim and heavy-duty insulation panel
BASF is presenting its high-performance insulation materials in a new application at the world’s flagship fair for architecture, materials and systems in Munich from January 14 to 19, 2019. The innovative high-performance products SLENTITE® and SLENTEX® are a new generation of super-slim aerogel-based insulation materials with outstanding material properties. BASF is presenting its first examples of applications in carbon concrete composite facade elements in a single-family house.
Slim concrete facades for residential cube using SLENTITE® and SLENTEX®
Combining new materials with renewable energy sources is the secret of success of housing of the future. Currently under construction in Leipzig is a modern, cube-shaped single-family house that puts this principle into practice. In a central location, the three-story building is being erected with a hybrid load-bearing structure of carbon concrete composite (C³) and reinforced concrete. The exterior exposed concrete shell is a highly durable precast C³ element 4 cm thick, while the inner shell, also of precast C³, is 6 cm thick.
To achieve an extra-slim wall construction, the new SLENTITE® and SLENTEX® high-performance materials can be used for the insulation between them, reducing the wall thickness in the non-load-bearing core by 50 percent over conventional insulation materials.
For the overall facade element construction, this means a thickness of 18 centimeters for a KfW 55 standard wall with 0.21 W/m² •K. Slimming down the exterior wall significantly facilitates not only new aesthetic approaches, but also a gain in space, which is becoming increasingly precious in inner-city building. In addition, the two high-performance insulation materials can be integrated in the automated production of the elements in the precast concrete plant without further system adjustments.
High-performance insulation in flat roofs
Owing to its slim profile, SLENTITE® is excellently suited to applications where conventional insulation materials reveal their limitations. To create same-level transitions such as between an interior room and a roof terrace or in openings for windows or doors, SLENTITE panels are the only feasible choice. Around elements installed in exterior walls such as roller shutter boxes or in radiator recesses, the novel insulation material also prevents thermal bridges as it is only half as thick as conventional materials.
Thresholds leading onto flat roofs can be executed without changes in levels, and projections in the insulation plane due to construction joints can be overcome without difficulty. In the single-family house in Leipzig, the roof terrace is being executed with a layer of SLENTITE® insulation. This permits a same-level transition without modification of the load-bearing structure – another milestone in the implementation of energy-efficient strategies in the construction sector.
SLENTEX® – flexible and efficient insulation
SLENTEX® is an easy-to-process and non-combustible material based entirely on mineral raw materials. As a single-layer, flexible mat, it is now available for a variety of applications in the construction and modernization sectors.
SLENTEX® is a highly efficient and extra-slim insulation mat. With a λD value of 19 mW/m • K, the material achieves much lower thermal conductivity than conventional mineral insulation materials and permits the construction of very slim wall constructions. Beneficially, the material is non-combustible, has an A2-s1, d0 fire class, and is ETA-certified.
SLENTEX® permits the diffusion of water vapor (µ ~ 5) while also being hydrophobic, thus making it ideal for facade applications.
