BASF is now introducing onto the market a new XPS (extruded polystyrene rigid foam, brand name Styrodur® C) that has an around 20 percent better lambda value than competitive products. BASF researchers made this major leap in insulation performance by integrating into the XPS finely-dispersed graphite particles which absorb the heat radiation and reflect it like a mirror.
BASF invented the technology in 1995 for its gray expandable polystyrene Neopor® (EPS). That is the reason why the new XPS insulation panels are called Styrodur® Neo and are available in gray.
Because of the higher insulation performance, which is achieved by the in-built infrared absorbers, the thickness of the panels can be reduced accordingly. Thus, Styrodur Neo is particularly suitable for the insulation of building interiors on walls, floors and ceilings but also for the insulation of thermal bridges and cavity walls. The new foam contains only air as cell gas and has the proven properties of Styrodur C which are of particular advantage in these applications: high compressive strength, low water absorption, resistance to rot, dimensional stability and durability.
Insulation material Styrodur C
The pressure-resistant, water-repellent, and rot-proof Styrodur C has been protecting houses from heat, cold and moisture for over 40 years, increasing the life of buildings, enhancing their value and improving the room climate. The various Styrodur C grades, which all contain only air as cell gas, differ mainly in their compressive strength.
