Extruded polystyrene (XPS) is a foam insulating material with closed cells. Approximately 93% of its weight consists of polystyrene, while in a small percentage it also contains additives, pigments and fire retardant.
The polystyrene crystals are mixed with special enhancement additives and environmentally friendly bulking gases, creating a viscous mixture. This mixture is homogenized under automatic and fully controlled temperature and pressure conditions, cooled and finally shaped into a desired specification plate. The uniform dispersion of fixed-size alveoli within the mass of the thermal insulating plate ensures the excellent thermal insulation properties of the fibro stir XPS plate.
The Fibrostir xps (WRS) Anapneoysas façade plate is applied to the thermal insulation of existing constructions and exterior renovations, while allowing the breathing of the building. This is achieved with the specific composition and structure of the alveoli, in Combination with surface treatment. With the application of the Fibrostir XPS plate (WRS) We save money for heating in winter and cool in summer, while achieving thermal comfort and protection of the building from the weather stresses.
