A best practice is design to realize the full service-life potential of the components and materials that comprise an assembly (or at least so that they can be efficiently reclaimed for reuse or recycling). The majority materials in a typical unitized glass and metal curtain wall system are float glass and extruded aluminium, both with extraordinary service life potential: indefinitely for the glass and hundreds of years for the extrusions if properly maintained. These gaskets are the вЂweak linkвЂ™ in the durability of the system (along with the sealants in an insulated glass unit, if present) and should be easily accessible for inspection, repair and replacement, if the potential for extended service life is to be realized. Once installed, the gasket seals are no longer available for inspection, repair or replacement, despite being subject to wear as they move within the groove. 14.1 is obviously not designed for maintenance. The prevention of water and air migration across the weather barrier is the most fundamental and important function of the faГ§ade system. At the top of the tongue is the business end of the unit the gaskets that act as the air and moisture barrier.

The tongue of the lower extrusion is free to slide up and down within the groove of the upper extrusion to accommodate relative movement between the adjacent units, one of the advantages of a unitized curtain wall system. Typical stack (horizontal) joint characteristic of a unitized curtain wall system. They are also more interconnected, interdependent and complex the panel components are bonded and fastened together in a manner that makes disassembly a challenge, and substantive in-service maintenance or repair impossible.ДЇigure 14.1.

The modular prefabricated unitized curtain wall systems, characteristic of faГ§ade systems today, are considerably more efficient to manufacture and install than the older stick systems. Complexity is yet another factor that can strip system resilience ( Zolli, 2012). Fisher (2013, loc 306вЂ“393) uses the 2007 I-35W bridge collapse in Minneapolis as an example of this.ДЄnother lesson from the resilience playbook is the downside of interconnectedness or interdependence systems that become overly interdependent are linked like dominoes and the failure of a single component can lead to system collapse or catastrophic failure. For example, the energetic pursuit of increasing efficiency often proves problematic: as systems evolve toward increasing efficiency, they typically lose redundancy-overefficiency can strip resilience. If the failure to anticipate the future need for renovation is indeed the reason why more practical and efficient faГ§ade intervention options are unavailable-leading to complete faГ§ade replacement as the dominant renovation, a strategy both costly and disruptive-have we then all been busy building tomorrowвЂ™s problems?ДЄ deeper study of resilience reveals considerations that may, at first, seem counterintuitive. Nonetheless, research thus far has yet to reveal a single verified example of a curtain wall system designed to accommodate maintenance and future renovation ( Patterson et al., 2012, 213).Д¬ontemporary unitized curtain wall systems may prove even more challenging to renovate than their stick-built antecedents.
