Aluminum view Curtain Wall

curtain wall system is an outer covering of a building in which the outer walls are non-structural, utilized to keep the weather out and the occupants in. Since the curtain wall is non-structural, it can be made of lightweight materials, thereby reducing construction costs. When Architectural Glass is used as the curtain wall, an advantage is that natural light can penetrate deeper within the building. The curtain wall Façade does not carry any Dead and live loads from the building other than its own dead load weight. The wall transfers lateral Wind Engineering that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, absorb sway induced by wind and Earthquake Engineering forces acting on the building, withstand wind loads, and support its own dead load weight forces.

This product points to light weight and transparency. Therefore, the Curtain Wall façade  also covers the exterior of the building, which usually consists of putting together aluminum frame and glass in the form of a lattice, as well as the possibility of being transformed from the inside space to the outside. This type of façade is considered as a dry façade.

The sophisticated concept fulfils the user’s high expectations of optimum quality, high insulation and ease of operation. The system gives a lot of design freedom by allowing very large dimensions up to 3 meters in height and up to a vent weight of 400 kg.

Thanks to the  “High Insulation”  upgrade, the system can achieve superior insulation levels down to 1.07 W/m2k (Uf value).

Furthermore, the system is available with a low threshold that creates a perfect continuity between theoutdoor spaces and improves the accessibility to the building. This accessibility and comfort is further improved by the solutions for automatic opening.

Systems and principles

Stick systems

The vast majority of ground-floor curtain walls are installed as long pieces (referred to as sticks) between floors vertically and between vertical members horizontally. Framing members may be fabricated in a shop, but installation and Glazing in architecture is typically performed at the jobsite.

Ladder systems

Very similar to a stick system, a ladder system has mullions which can be split and then either snapped or screwed together consisting of a half box and plate. This allows sections of curtain wall to be fabricated in a shop, effectively reducing the time spent installing the system on site. The drawbacks of  using such a system is reduced structural performance and visible joint lines down the length of each mullion.

Unitized systems

Unitized curtain walls entail factory fabrication and assembly of panels and may include factory glazing. These completed units are installed on the building structure to form the building enclosure. Unitized curtain wall has the advantages of: speed; lower field installation costs, and Quality Control within an interior climate-controlled environment. The economic benefits are typically realized on large projects or in areas of high field labor rates.
