Type A Isospan

Izospan Type A is a windproof and moisture-protective, vapor-permeable membrane designed to protect thermal insulation layers in roofing, façade, and wall systems from external environmental effects. The material allows water vapor accumulated inside the structure to escape while helping prevent wind, dust, condensation, and atmospheric moisture from penetrating the insulation layer. Izospan A is commonly used in ventilated façades, pitched roof constructions, frame walls, and various building insulation systems. The membrane helps maintain the efficiency of thermal insulation, extends the service life of structural elements, and supports a healthier indoor microclimate. Lightweight, flexible, and easy to install, this material offers practical use during construction and is considered a reliable protective solution for both private residential buildings and commercial projects.
