Materiales de Sellado y Barreras
Membranas barrera anti-radón certificadas por coeficiente de difusión según ISO/TS 11665-13. Incluye membranas bituminosas (SBS/APP), membranas de polietileno HDPE/LDPE, barreras líquidas para gases, sistemas de poliuretano proyectado, sellantes para grietas y juntas, y sellos para penetraciones de tuberías. Esenciales en obra nueva y efectivos cuando se combinan con despresurización activa, aunque no se recomienda como solución independiente.
Application
Intervention Type
Radon barriers and membranes reduce both diffusion and convection, providing passive protection when properly installed. From bituminous sheets to polyethylene membranes and projected systems.
Browse certified products from manufacturers including Danosa, Soprema, and Visqueen. Best used as complementary measures with active depressurization systems.
