Use this section to specify aluminum wall louvers, either fixed or operable, with insect or bird screens.
This section includes aluminum or galvanized steel wall louvers that are not connected to ductwork, with or without bird and insect screens.
Louvers connected to ductwork are typically specified in Division 23 – Heating, Ventilating and Air Conditioning.
Straight blade louvers are the lowest performing type of louver as they do not provide resistance to water penetration. This type of louver is often used for aesthetic reasons only, to close off an opening while allowing air movement.
Water baffle louvers provide increased resistance to water penetration, however, water entering the louver assembly must cascade down the louver assembly to the bottom since there is no weep drainage system.
Drainable blade louvers collect water entering the louver assembly and route it to downspouts contained in each jamb frame. These are the best-performing louvers.
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.
