Minimizing Condensation
Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained thro ugh your EFCO representa­tive. Condensation will form on any surface when unfavorabl e cond itions (interior temperature and relative humidity and exterior temperature) are present. When the formation of excessive condensation is a concern, it is highly recom m ended that a design pro­fessional is utilized to perform an analysis of the shop drawings to recommend the best possible installati on methods. Please con­tact your EFCO representative for information on EFCO's Thermal Analysis Services. Many current installation practices lead to an increase in the possibility of the formation of condensation. Though not all inclusive, the list of examples below illustrates conditions under which condensation is lik ely to occur:
1. Bridging system thermal break with non-thermally broken metal flashing or lintels th at are exposed to the exterior
2. System exposure to cold air cavities
3. Interior relative humidity levels not maintained at recommended levels, see EFCO’s “Understanding Condensa­tion” brochure
4. Inadequate separation between system and surrounding condition at perimeter
5. Product combinations during the shop drawing stage that result in bridging thermal breaks
of one or all products involved

SECTION I: General Notes and Guidelines
The Series 526 is a thermally broken impact framing system that is designed for impact resistance of windborne debris. It can be used as a single-span storefront window wall, a punched opening system, or a ribbon window system. Various glazing capabilities allow the 526 to be used as either wet sealed or dry gasket glazed. Both the wet sealed and the dry glazed are outside glazed. The dry glazed system can be inside glazed also except the transom above the door.
The Series 526 thermally broken impact system contains primarily stock length material with in-the-field fabrication. Entrance doors are also an integrated part of this system, utilizing frame members and hardware that accommodate doors and door hardware that will withstand impact from windborne debris.
1. Check the shop drawings, installation instructions, and glazing instructions to become thoroughly familiar with the project. The shop drawings take precedence and include specific details for the project. The installation instructions are of a general nature and cover the most common conditions encountered.
2. Check all materials on arrival and be sure you have everything required to begin installation. See Section II “PARTS IDENTIFICATION CHART” for parts cross-referenced.
3. All work should start from benchmarks and/or column centerlines as established by the architectural drawings and the general contractor. Installers should check building construction for compliance with architectural documents to ensure the proper window system foundation is available before installation.
4. All materials are to be installed plumb, level, and true.
5. Protect materials after erection. Cement, plaster, alkaline solutions, and acid based materials can be harmful to the finish. Clean exposed finished surfaces with a mild detergent and water. No abrasive cleaning agent should be used.
6. Throughout these instructions the term “SEALANT” will appear. For the purposes of these instructions, sealant is to be defined as the following:
SEALANT - A weather resistant, gunnable liquid filler which when cured provides a resilient, flexible (± 50% movement capability) air and water seal between similar and dissimilar materials. All sealant must meet ASTM C 920, CLASS 50.
NOTE: All sealant must be compatible with all surfaces where adhesion is required, including other sealant surfaces. All frame surfaces should be clean, dry, and frost free. If a primer is required, it must be applied to clean surfaces. All perimeter substrates shall be clean and properly treated to receive sealant.
NOTE: These installation instructions are general in nature, a supplement to the approved shop drawings, and must be used in conjunction with those drawings.
