Curtain-wall Systems

UNITIZED

Unitized curtain wall systems are composed of large glass units that are created and glazed within factory and then sent to construction site. Once on site, the units can then be hoisted onto anchors connected to the building. High quality, due to tight tolerances of fabrication in a climate-controlled environment, is only one hallmark of this type of system. Since there is no on-site glazing, another major benefit of using a unitized system is the speed of installation. This system is well suited for cases where there is a large volume of prefabricated unitized panels required, where there are higher field labor costs (thereby shifting the labor to a more cost effective factory work force), where higher performance is needed (for wind loads, air/moisture protection, seismic/blast performance), for taller structures, and more regular conditions for panel optimization.

SEMI-UNITIZED

Semi-Unitized curtain wall systems are composed of large glass units that are created and glazed within factory and then sent to construction site. Once on site, the units can then be hoisted onto anchors connected to the building. High quality, due to tight tolerances of fabrication in a climate-controlled environment, is only one hallmark of this type of system. Since there is no on-site glazing, another major benefit of using a unitized system is the speed of installation. This system is well suited for cases where there is a large volume of prefabricated unitized panels required, where there are higher field labor costs (thereby shifting the labor to a more cost effective factory work force), where higher performance is needed (for wind loads, air/moisture protection, seismic/blast performance), for taller structures, and more regular conditions for panel optimization.

STICK-WALL

The vast majority of low to mid-rise curtain walls are installed using Stick system. Long pieces of aluminium (hence the name stick) are inserted between floors vertically and horizontally between vertical members to support and transfer the load of the glass back to structure. Most of the erection and glazing for a stick-built system is done on site. One of the benefits of stick-built systems is it's economic frindliness for facades that have lower required volumes and many complicated conditions. The lead times for these types of systems are often much shorter for fabricated materials to be delivered to the site and allow forlessup front staging. This is shorteren comparison to a utized system, where six months to a year can be required for this process. However, the trade-off is that the installation takes longer to complete on-site. You also need a significant amount of space installation and storage of materials on the site, which can be difficult in many high-traffic cities with tight job sites.

SKY LIGHT

Skylights are light transmitting fenerstration (elements filling building envelope openings) formaing all, or portion of, roof of a building's space for daylighting purposes.
Skylighting types include roof windows, unit skylights, tubular daylighting devices (TDDs) sloped glazing and custom skylights. Uses include:
1 - Daylighting elements used to allow direct and/or indirect sunlight, via toplighting.
2 - Providing a visual connection to the outdoor envoironment to interior occupants.
3 - Sustainable building-passive solar heating and with operable unitsl ventilation for passive cooling and fresh air exchange.
