AQ prof Izospan

AQ proff Izospan is a reinforced, three-layer hydro-windproof and vapor-permeable membrane designed to provide reliable protection for thermal insulation layers in roofing, façade, frame wall, and building insulation systems. The material has a structure based on a microporous polymer membrane reinforced on both sides with polypropylene nonwoven fabric, which helps prevent wind, condensation, and atmospheric moisture from penetrating the structure while allowing water vapor formed inside the insulation layer to escape freely. AQ proff Izospan helps reduce heat loss, maintain the efficiency of thermal insulation, and extend the service life of building structures. Thanks to its high strength, the material provides dependable performance during installation and long-term use, making it suitable for pitched roofs, ventilated façades, frame walls, externally insulated walls, attic floors, and intermediate floor structures. With practical installation, durable protective properties, and technical performance suitable for professional construction projects, AQ proff Izospan is a functional membrane solution for private houses, commercial buildings, and large-scale construction works.
