Standard Guide for Remedying Structural Silicone Glazing
SIGNIFICANCE AND USE
4.1 Guidelines are provided for remedying existing SSG installations. Refer to Guide C1401 for a complete discussion of proper SSG design, installation, and materials.
4.2 Due to the unlimited range of materials that may be used in a particular building, and because each design is unique, the information contained in this guide is general in nature.
4.3 This guide should not be the only reference consulted when designing remedies for SSG. For example, the local building code and the manufacturers' product literature for the actual materials used, if known, also should be considered. The sealant manufacturer(s) should be involved fully with the remedial design.
4.4 This guide is intended to be a resource, but it is not a substitute for experience and judgement in designing remedies for the specialized types of construction discussed. It is intended to be used in conjunction with other resources as an aid in remedying problems with existing SSG.
SCOPE
1.1 This guide provides recommendations for remedying existing structural sealant glazing (hereinafter called SSG) installations in situ. Remedial work may be necessary when a lite of glass is replaced, for routine maintenance, or after distress is discovered. This guide focuses on large-scale remedies, not isolated repairs or maintenance.
1.2 Committee C24 is not aware of any comparable standards published by other organizations.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
