Unitized curtain wall system ALT EF65 was designed to create curtain walls glazing using ready modules (elements), which were assembled in a workshop beforehand. This way of assembling allows to omit the process of scaffold installation and makes high-rise construction a lot easier.
Traditional curtain wall
The main components of this system are frame profiles and transom bars which form units. Infill units in such constructions are fixed with the help of glazing beads and wedge gaskets. Gasket kit is used for joining and caulking of the units together.
ALT EF 65 system allows to fully assemble in a workshop and easily install on the building sight large panels and glazed units (including installing of such elements as stationary window frames, ventilation systems and special below-window wall panels).
Unitized curtain walls are assembled in the following order
First step Units from aluminum profiles and IGUs (glass, solid infill units) are assembled on a plant.
Second step Land surveying of the building and bearing structures installation on a slab.
Third step Produced units are packed and shipped to the building sight in containers, where they are hanged on the bearers fixed to the slaps.
Unitized curtain wall advantages
Due to high-level of workshop assembly unitized curtain walls have advantages over mullion-transom faГ§ade in mounting terms and assembled structure’s quality, meaning:
Elements standardization during designing stage, high quality of assembly operations, close control during manufacturing process, final quality inspection;
Building area assembling with fewer working operations leads to human factor effect (defects occurring) reducing;
Construction time almost doesn’t depend on weather conditions, as all the constructions are assembled in manufacturing workshop;
Assembling is performed floor-by-floor, finishing works could be started earlier with a closed building facade;
Possibility of assembling at low temperatures without any significant changes in technical process;
Possibility of faster occupation of the building, it’s putting into operation and investment recovery.
