FIELD: building, particularly polyvinylchloride profiles for facade framing openings in buildings and building structures. ^ SUBSTANCE: profile system includes at least one profile forming window frame, at least one profile defining window leaf and at least one profile forming transom bar and having T-shaped cross-section defined by flange and post. Transom bar forming profile is divided by partitions into several chambers. One chamber is adapted for reinforcing bar installation and is provided with extensions directed into chamber. Transom bar flange is divided into central and side chambers by partitions extending in parallel to longitudinal post axis. Central chamber is defined by the first partition from post side. The first partition is parallel to rear flange wall and spaced a distance exceeding partition thickness relative inner surface thereof along longitudinal axis towards post chamber. Each profile adapted for glazing is provided with grooves for sealing member arranging from outer glass side and with grooves for glazing fillets location in air-tight manner from inner glass side. Central chamber part of transom bar has at least one additional partition located inside chamber in plane of rear flange wall so that at least one additional cavity is created in chamber. The first partition is spaced a distance exceeding outer profile walls relative rear flange wall. Sealing means of glazing fillet is made as removable packing located in slot formed in side fillet surface facing glass. Working part of packing has two teeth in cross-section. Teeth apexes face glass surface. Tooth defining outer packing surface extends at an angle of not less than 45° to packing axis. Teeth apexes are provided with surfaces resting upon glass surface. ^ EFFECT: improved performance of window and door structures due to reduced heat losses through different structure parts, increased reliability and service life thereof. ^ 13 cl, 7 dwg |
