Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained through your EFCO
representative.
Condensation will form on any surface when unfavorable conditions (interior temperature and relati ve humidity and
exterior temperature) are present. When the formation of excessive condensation is a concern, it is highly recommended that a
design professional is utilized to perform an analysis of the shop drawings to recommend the best possible installation methods.
Please contact your EFCO representative for inf ormation 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 likely to occur:
Note: This document is to be used in conjunction with the standard installation
instructions.
Note: These installation instructions are a supplement to the approved final shop drawings
and are to be used in conjunction with those drawings.
Minimizing Condensation
1. Bridging system thermal break with non-thermally broken metal flashing or lintels that 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 perimet er
5. Product combinations during the shop dr aw ing stage that result in bridging thermal breaks of one or all
products involved

Section I: General Notes and Guidelines
I. HANDLING / STORING / PROTECTING ALUMINUM - The following precautions are
recommended to assure early acceptance of your products and workmanship.
A. HANDLE CAREFULLY - Store with adequate separation between components so
the material will not rub together. Store the material off the ground. Protect materials against weather elements and other construction trades.
B. KEEP MATERIAL AWAY FROM WATER, MUD, AND SPRAY - Prevent cement,
plaster, and other materials from contacting with and damaging the finish. Do not
allow moisture to be trapped between the finished surface and the wrapping material.
C. PROTECT MATERIALS AFTER ERECTION - Wrap or erect screens of plastic
sheeting over material. Cement, plaster, terrazzo, and other alkaline materials are
very harmful to the finish and are to be removed with soap and water before hardening. Under no circumstances should these materials be allowed to dry or permanent staining will occur.
II. GENERAL GUIDELINES - The following practices are recommended for all installations:
A. REVIEW APPROVED SHOP DRAWINGS – Become thoroughly familiar with the
project. Shop drawings govern when conflicting information exists in these installation instructions.
B. INSTALL ALL FRAMING MATERIAL PLUMB, LEVEL, AND TRUE – Proper
alignment and relationships to benchmarks and column centerlines, as established
by the architectural drawings and the general contractor, must be maintained.
C. The sequence of erection should be coordinated with the project superintendent to
prevent delays and minimize the risk of material damage. Note: If preset an-
chors are required, coordinate and supervise anchor placement with the
general contractor.
D. Verify that all job site conditions and accompanying substrates receiving the instal-
lation are in accordance with the contract documents. If deviations occur, notification must be given IN WRITING to the general contractor and differences resolved before proceeding further with the installation in the questionable area.
E. Prevent all aluminum from coming in direct contact with masonry or dissimilar ma-
terials by means of an appropriate primer.

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 on which adhesion is re-
quired, 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.
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.

Section V: PUNCHED OPENING & RIBBON WINDOWS
(Frame Opening & Frame Sealing)
Punched opening and ribbon window elevations are typically used for small openings or openings of
limited height where the frames can be partially assembled off-site, moved to the jobsite, and then
groups of frames are snapped together. This allows groups of frames to be set into the opening all at
one time. Custom extruded aluminum anchors are slid into the heads and sills during frame assembly.
This method of anchorage is limited due to certain structural limitations. Please consult with the
structural engineer responsible for the shop drawings for your project. This type of installation also
requires that there be no obstructions (such as floor slabs or columns) that prevent the frames from
being installed from the interior.

Section V: Vertical Splice Joints
STEP #1 LOCATE SPLICE JOINTS
A. Splice joints should occur at spandrel areas (if possible). Refer to the approved shop
drawings for actual locations.
B. Depending on job requirements, the mullion splice may be shop or field assembled in
the top of the lower mullion. The cover splice is attached to the bottom of the upper
mullion. Where head clearance is insufficient to allow the top mullion to be lifted over
the splice sleeves, retractable splices should be used. The splices are to be taped into
the bottom of the top mullion and dropped down to the stop screw in the mullion
below.
C. GENERAL NOTE: The following pages depict a splice joint of 1/2”. This will allow plus
or minus 1/4” of movement for each splice location. Thermal expansion and live
deflection requirements should be considered when determining the location and
quantities of splice joints. If the total amount of movement cannot be accommodated
locating splices at every other floor or alternatively at each floor, expansion
horizontals or some alternative method should be used. Contact EFCO for further
evaluation.
D. Refer to this section for pressure cover splice locations, mullion splice locations, and
sealing instructions.
E. Once a final check of expansion joint placement and mullion position is made, the final
match drilling of mullion through anchor holes may be completed.
