Application of Styrofoam in the Elements of Building Constructions

摘要

The article presents the possibilities for the contemporary application of Styrofoam in the elements of building structures. Having in mind that Styrofoam belongs to a group of highly flammable materials, 5% of combustion retarder - so called "retardant" - needs to be added to the amount when produced for structural building elements. That kind of Styrofoam is called "selfextinguishing" contrary to "normal" that does not contain that substance. The Article also shows the way in which building elements are constructed (external and interfloor construction), made out of Styrofoam using "Plastbau" technology. A possibility to use exterior wall panels 'Plastbau' under weather conditions of Saint-Petersburg has been considered. Temperature distribution along a wall's section as well as a heat flow going through a building enclosure 'Plastbau' have been also analyzed herein.
