Description:<\/strong><\/span><\/p>\n

URSA TERRA PLUS 68 Ph<\/strong> is a compact, water-repellent glass mineral wool board with a density of 68 kg\/m\u00b3<\/strong>, specially developed for drywall systems, front wall cladding, and plasterboard partition walls. Thanks to its exceptionally high airflow resistance (AFr > 5 kPa\u00b7s\/m\u00b2<\/strong>) and density, it provides maximum acoustic performance at a minimal thickness of 50 mm<\/strong> \u2014 perfect for CW 50 profiles<\/strong>.<\/p>\n
