Series 5600 Outside Glazed Installation Instructions
Section I: General Notes & Guidelines
F. Follow EFCO framing installation and glazing instructions.
G.
Verify contents of all material shipments received upon arrival. Verify
quantities and correct finishes. NOTIFY EFCO IMMEDIATELY OF ANY
DISCREPANCIES OR DAMAGE, THAT MAY HAVE OCCURRED.
H. 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.
BUTYL SEALANT- A non-skinning, non-hardening material (NAAMM
Reference Standard 5C-1)
NOTE: All sealant must be compatible with all surfaces where adhesion is
required, including other sealant surfaces. All frame surfaces should
be clean, dry, dust, 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.
This system is designed and has been tested to utilize butyl or
silicone sealants at all internal joineries, i.e., joint plugs, gasket
intersections, etc.
Regardless of the sealant used, the customer should contact the
sealant manufacturer to determine compatibility and adhesion.
Follow sealant manufacturer's proper application procedures and
quality assurance programs for weather sealing.
Maintain caulk joints as shown in the approved shop drawings.
Unless specified otherwise, most sealant manufacturers recommend
a 3/8” minimum perimeter caulk joint. A 3/4” minimum joint is
recommended at the head condition to accommodate thermal
expansion and contraction.
Anchoring surfaces of perimeter construction must be level and
plumb within the adjustable limits of the head, jamb, and sill
framing.
