Dacha B - is a two-layer vapor barrier material which is consisting of a non-woven polypropylene fabric and a functional polymer coating. It preserves the thermal insulation properties of the insulation and extends the service life of the entire structure.
The Field of application:
It is used to protect the heat-insulating layer and structural elements from the penetration of water vapor from inside the room in insulated- suspended roof systems, walls and ceilings of frame constructions.
Features and advantages:
The applicable temperature range is minus 40 °C to plus 80 °C.
