"By supporting structures high-rise buildings increased demands for fire resistance, – says Sergei Liadov, spokesman for the company's "City-XXI Century". – In particular, for buildings with more than 100 m limit fire load-bearing structures set at 4 o'clock. " For the same reasons of fire safety for the facades can not be used plaster multilayer system. Read more here: New York Museums. Therefore, the facades of skyscrapers – is mainly ventilated curtain construction consisting of steel sections and light panels of glass, aluminum or polymers. Popular ventilated system, finished with natural or artificial stone, sheet metal, fiber concrete (concrete with fibers made of metal and polymers). Among the newest types of veneer – ceramic with fire hardened borosilicate glass panels and metal foam. Particular attention is paid to the window construction.

Above 70 feet is permitted install only the deaf (undisclosed) windows, because at this altitude banal draft becomes a powerful air flow that can break a window. In addition, high-rise buildings have great wind load, due to which windows can not only break, but will be pulled out of what is called "the root". Now most of the construction of residential buildings install pvc windows. To the upper floors of optimal strength and thermal insulation characteristics of window systems are made on the basis threechamber pvc profiles with a thickness of 58 mm: for example, such as PROPLEX-Optima. Several claims are directly to the glass itself. In countries EU's current construction standards, according to which, starting from the fourth floor should be installed only safe forms of glass – tempered or laminated glass.
