t is described herein a system of door and window sashes made of compact aluminium profile. The system in question is characterised by potential perimetrical securing, the shape of the inside reinforcement angles of the frame and the provisions meant for sealing, thermal, and sound insulation coverage. It is presented with or without thermal insulation and comprises the groove 4 at the panel profile 2, which is sufficiently dimensioned to peripherally receive, on the panel frame 2, the blades 21 connected with angles 22 at the corners of the frame, where along the entire sequence of the blades 21 and angles 22, a plurality of peripherally protruding pins 24 are located and destined to secure into respective recesses 23 on the frame profile 1, at mere rotation of the handle 25. It is also disclosed the use of a reinforcing angle 15 of the frame profile 1 and 15, the panel profile 2, and the perimetrical elastic seal 8 whose distinct two-limbed construction ensures, in combination to the central inner elastic sealing members 16a, 16b, high level sealing. |
