S-5500 SSG and Captured Corner Mullion Installation Instructions
Section I: General Notes
F.
Follow EFCO framing installation and glazing instructions.
G.
Verify contents of all material shipments received upon their 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, gunable 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 on which 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. A 3/4” minimum joint is required at the jamb conditions to
accommodate installation.
Anchoring surfaces of perimeter construction must be level and plumb
within the adjustable limits of the head, jamb, and sill framing.
