BASF is enlarging its product range of extruded polystyrene rigid foam panels (XPS) with the brand name Styrodur® to include a new product: Styrodur® 3000 CS has the same thermal conductivity of 33 mW/mK across all panel thicknesses from 30 to 240 mm. The thermal conductivity of the insulation panels is up to 15 percent better than standard Styrodur grades.
The new production technology involves joining together several thinner panels with excellent technical properties. This now means panels with a thickness of more than 140 mm can be manufactured with improved thermal conductivity. “With this technology, for which we have filed a patent application, BASF offers an extruded foam providing the proven high quality of Styrodur with lots of advantages for builders, the building material suppliers, planners and architects,” says Klaus Ries, who is responsible for BASF’s styrene foams business in Europe.
Multi-use insulation panel with many advantages
Besides improved thermal conductivity, the new technology also leads to faster availability of thick insulation panels. The resulting flexibility benefits primarily the building material suppliers and construction site management.
The new Styrodur® 3000 CS provides architects and planners with a product for many structural and civil engineering applications. Using Styrodur® 3000 CS simplifies calculations as a result of it having the same thermal conductivity for all thicknesses. Thanks to the better thermal conductivity, the U-values (thermal transfer coefficient) required by law can be achieved with much thinner boards. In addition, it is now possible to install the insulation in one layer, allowing the insulation to be installed by the craftsman at the building site more quickly and cost-efficiently. This means that Styrodur® 3000 CS insulation is particularly economical in perimeter areas and inverted roofs.

Styrodur® insulating material
The rigid, water-repellant and rot-proof Styrodur® has been protecting houses against heat, cold and moisture for over 50 years. Besides offering reliable product quality, the green XPS is also noted for continuous work on approvals. There are more officially approved uses for Styrodur than for any other XPS product in the market. Insulation with Styrodur increases the lifespan of buildings, enhances their value, and improves the climate inside them. The different Styrodur grades, which contain air as the cell gas, differ primarily in their compressive strength.
