BASF becomes the first XPS manufacturer to obtain technical approvals (construction type) for products welded in a contactless process
| Subj: Press-releses
In mid-July 2017, BASF became the first XPS producer to receive a construction type approval for extruded foam boards welded in a contactless process. The general technical approvals Z-23.31–2083 and Z-23.33–2084 pertain to Styrodur® SQ in inverted roof and perimeter applications. Under the brand name Styrodur® 3000 SQ, products are sold with nominal thicknesses of 200, 240, and 300 mm, which are joined together in layers of three, four, or five to form a single board by means of contactless thermal welding applied across their whole surface.
These new products complete BASF’s recently fully updated range, which boasts a uniform declared lambda value of 0.033 W/(m·K) in all board thicknesses. The compressive stress characteristics of the new 3000 SQ types have also been improved further. This provides architects, planners, and homeowners with a leaner wall construction coupled with increased insulation performance. The permissible compressive stress over 50 years at < 2% deformation, tested in accordance with DIN EN 1606, has been increased from 110 to 130 kPa.
