Glazed Aluminum Curtain Walls
Use this CSI 3 part SimpleSpecs™ master specification to specify aluminum-framed glazed curtain walls.
Aluminum-framed glazed curtain walls are capable of spanning greater distances than aluminum storefront and can be used in taller assemblies and floor-to-floor applications in mid and high-rise buildings.
With appropriate adapters or subframes glazed curtain walls can accept entrance doors.
Spandrel panels may be either glass or metal panels that are glazed into the curtain wall assembly.
Several different glazing methods are available:
– Pressure glazed: Glass panels are held in place by pressure plates that capture the glass edges and are attached to the curtain wall framing by bolts positioned between glass panels.
– Four-Sided Structural silicone glazed: Glass panels are held in place by structural silicone glazing sealer applied to the aluminum framing before the glass panels are placed. Temporary retainers are typically used to hold the glass in position while then sealer cures, then rermoved. A bead of silicone sealer is then applied between the glass panels. No visible metal occurs on the outside of these joints.
– Two-Sided Structural Glazed: Similar to four-sided structural glazed except that two opposing glass edges, typically top and bottom, are secured by aluminum framing components.
Finishes for exterior aluminum must provide resistance to weathering and ultraviolet degradation. Class II anodizing and lower quality painted coatings may not suitable for exterior use.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
