YKK AP DELIVERS SIMPLE, QUALITY UNITIZED CURTAIN AND WINDOW WALL SOLUTIONS For EVERY PROJECT. In an evolving construction industry, increasingly tight schedules and rapid building closeins are critical to success. Unitized fenestration systems are fabricated, assembled and glazed in the shop, then shipped to the jobsite for installation. Unitized curtain walls entail factory fabrication and assembly of panels and include factory glazing. These completed units are hung 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. Kawneers 2500 PG Wall curtain wall system is a unitized solution engineered to meet these criteria and more. It is offered in a wide range of options that can be customized to each project. Stock lengths offer glazing contractors the flexibility of providing fabrication and preglazing under controlled conditions in their own shop. Unitised Curtain Wall 7 Introduction An alternative to the AA 201 structurally glazed system, the AA 265 is a dry glazed solution incorporating a 3chamber system and overlapping gasket design for optimum weathertightness. Curtain walls are classified by their method of fabrication and installation in two categories: stick built and unitized systems. Unitized curtain wall systems are comprised of large units that are assembled and glazed in the factory. They are then shipped to the job site and erected on the building faade. The only Curtain Wall CNC machine for aluminum extrusions with vertical and horizontal clampdown fixturing. In 1999, CNT built the first of several machines designed to drill and mill long aluminum extrusions for preengineered commercial building exterior wall coverings, known as curtain walls.

Lockheed provides design, engineering, production, fabrication, application, and installation services for FM Grahams captured unitized curtain wall system and structurally glazed unitized curtain wall. Sep 08, 2011Enclos, a facade engineering and curtainwall design company, is one of the largest specialty contractors in the United States. Enclos is expert in the design, engineering, fabrication, assembly and erection of custom facade systems, providing complete designbuild services to the construction marketplace. Unitized curtain walls are generally fabricated concurrently with the erection of steel and concrete building frames and slabs. Since structural frames and curtain wall fabrication typically hold to different tolerance levels, unitized curtain walls may not always fit within the space that is. Each curtainwall application is tailored to meet the specific needs of a project from engineering considerations, to thermal performance and nuances of the architectural designintent. The unitized system is developed through shop drawings and mockup testing, before fabrication begins at Islands Calverton facility. This accommodates thermal expansion and contraction, interstory differential movement, concrete creep, column foreshortening, andor seismic movement. Most unitized curtainwall systems are installed in a sequential manner around each floor level, moving from the bottom to the top of the building. A curtain wall is designed to resist air and water infiltration, absorb sway induced by wind and seismic forces acting on the building, withstand wind loads, and support its own dead load weight forces. Curtain wall systems are typically designed with extruded aluminum framing members, although the first curtain walls were made with steel frames. Unitized curtain wall is the fastest way to enclose your building in a glass faade. We offer aluminum and glass curtain wall from the leading fabricators in the US, Canada and Europe.
