BASF: Super-slim High-performance Insulation Creates Extra Space in Construction and Transportation
2019-09-27    [Source:BASF]

BASF is showing at K show its innovative, super-slim high-performance insulation materials in new applications. The innovative high-performance products Slentite and Slentex are a new generation of energy-efficient aerogel-based insulation materials with outstanding material properties. The company is presenting new examples of applications in carbon concrete facade elements and motorhomes.

Slim concrete facades for residential buildings

The use of new materials in combination with renewable energies is the secret of success for the housing of the future. In a pilot project in Leipzig, a house is being built with a hybrid load-bearing structure of carbon concrete and reinforced concrete. To achieve particularly slim wall construction, the new Slentite and Slentex high-performance materials can be used to create an insulating layer between the layers of concrete, reducing the wall thickness by up to 50 % over conventional insulation materials. Slimming down the exterior wall significantly facilitates not only new aesthetic approaches, but also a gain in space, which is becoming precious in inner-city building. In addition, the two high-performance insulation materials can be integrated in the automated precasting of the elements in the concrete plant without further system adjustments. With the flexible Slentex insulation mat, even organically shaped wall elements can be produced, opening up totally new scope for aesthetics in construction.

High-performance insulation in the automotive sector

Owing to their outstanding product properties, Slentite and Slentex are ideal for areas where conventional insulation materials are unsuitable. Saving space is a key criterion for motorhomes, caravans and in the transport industry. The prototypical motorhome, which is being fabricated for K 2019 in cooperation between a well-known recreational vehicle and motorhome manufacturer and BASF, shows how the slim insulation materials help to create valuable space for interior use. Another milestone in the implementation of energy-efficiency strategies and a new field of application for high-performance insulation.

Slim panel for all climates

Slentite is the first purely polyurethane-based aerogel ever to be produced. The heavy-duty aerogel insulation panel, which consists of around 90 % air and is breathable, permits insulation up to 50 % slimmer than conventional. As a pioneering high-performance insulation material, Slentites open-porous structure creates according to the company a pleasant indoor climate and helps to cut energy costs. The very good insulating performance (λ = 18 mW/m•K) is also coupled with excellent processing qualities. The clean, dust-free panels can be easily cut to size on site and applied directly to walls or coated beforehand.

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. 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 structures. Beneficially, the material is non-combustible, has an A2-s1, d0 fire class, and is ETA-certified. It also permits the diffusion of water vapor (μ ~ 5) while also being hydrophobic, thus making it ideal for facade applications.
