Innovations of aluminium–glass structures

Nagrinėjama aliuminio fasadų istorijos raida, palyginimas su dabartinėmis fasadinėmis aliuminio–stiklo konstrukcijomis. Apžvelgiamas projektuojamų konstrukcijų projektavimas–tvirtinimas, skaičiuojamų apkrovų vertinimas pastatų fasadams. Nagrinėjamos sistemos, atskleidžiami jų privalumai, įtaka pastatų statybai. Analizuojamas bendras stiklo ir metalinių konstrukcijų darbas, projektavimo silpnybės. Pateikiamos langų, stiklo projektavimo terminės charakteristikos.Santrauka anglų kalba. Using the morder element curtain wall systems possible assem-bling speed is extremely fast. Approx 1000 m2 of curtain wall facade is able to be assembled in two weeks. The insulated glass units in nowadays has limits for manufacto-ry just almost just from logistics point of view – the manufactu-red glass unit is able to be temepered in 3m height and 7m wi-de – needed careful transportation and special lifting devices to assemble such heavy glass units. With new low emission foils for glass, and used krypton or argon gas in it, insulated glass unit (with two layers or three) is able to reach 0,5 W/m2K of U value, which was not reacheble almost year ago. Passing through the history of usage in curtain walls systems, this article describes the innovations of alumi-num – glass constructions industry, the advantages of design accesibility for architects, consumers, designers and assessors of aesthetics. Shortly examined aluminium glass systems, it‘s advantages in production, assembling stages. Article submits the new possibilities for aluminium profiles, it‘s U-value to meet new standards of requirments in this modern age
