The Use of Structural and Thermal Insulation Foam Gypsum in the Construction and Reconstruction of Buildings. Problems and Prospects

In recent years, during the construction of construction projects for various purposes, the use of modern heat-insulating and structural-heat-insulating materials on a mineral basis (high-void porous ceramic products, aerated concrete, ultra-lightweight expanded clay concrete) has gradually increased, the main advantage of which, in addition to high thermal and sound insulation characteristics, is also incombustibility and relatively low cost. One of these materials is monolithic foam gypsum, which can be used for insulating attic and soundproofing interfloor floors both in new construction and in the reconstruction of existing buildings. The article presents the experience of using monolithic foam gypsum with a density of 250–300 kg/m³ in the overhaul and restoration of the object of historical and cultural heritage – the building of the Hospital of War Veterans in Ufa, built at the end of the 19th century, which made it possible to provide the required thermal insulation of the attic ceilings, sound insulation and fire protection of metal structures of the interfloor ceiling without increasing the load on the load-bearing walls and foundations of the building, as well as perform work at negative air temperatures inside the room. It is noted that, despite the existing positive experience, the widespread introduction of foam gypsum in construction practice is hindered by the absence of this material in Set of Rules 50.13330.2012 “Thermal protection of buildings” and in the estimated standards.
