Minimizing Condensation
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 (interiro temperature and
relative humidity and exterior temperature) are present. When the formation of extensive 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 information on EFCO's Thermal Analysis Serv ices.
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 that
are exposed to the exterior
2. System exposure to the 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 conbinations during the shop drawing stage that result in bridging thermal
breaks of one or all products involved

SECTION I: GENERAL NOTES AND GUIDELINES
PAGE 1
NOTE:
THESE INSTALLATION INSTRUCTIONS ARE A SUPPLEMENT TO
THE APPROVED SHOP DRAWINGS AND MUST BE USED IN
CONJUNCTION WITH THOSE DRAWINGS.
1.
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 com-
ponents so material will not become scratched or rubbed at points
of contact. Store off the ground. Protect against weather elements
and other construction trades in adjacent areas of the job site.
B. KEEP MATERIAL AWAY FROM WATER, MUD, AND SPRAY - Prevent cement,
plaster, and other materials from coming in contact 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. Cement, plaster, terrazzo, and other alkaline materials are
very harmful to the finish and must be removed with water and mild
soap before hardening. Under no circumstances should these
materials be allowed to dry or permanent staining will occur.
GENERAL GUIDELINES - The following practices are recommended for all
2.
installations.
A. REVIEW THE APPROVED SHOP DRAWINGS to become thoroughly familiar
with the project.
B. INSTALL ALL FRAMING MATERIALS PLUMB, LEVEL, AND TRUE - Proper
alignment and relationships to benchmarks and column center lines,
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. IF PRESET ANCHORS ARE REQUIRED, COORDINATE
WITH THE GENERAL CONTRACTOR AND SUPERVISE THE LOCATION.

SECTION I: GENERAL NOTES AND GUIDELINES CONT.
D. Verify that all job site conditions and accompanying substrates
receiving the installation 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. Coat all aluminum, to be placed directly in contact with masonry or
dissimilar materials, with a heavy coating of bituminous primer such
as zinc chromate.
F. Follow EFCO’s framing installation and glazing instructions.
G. Verify the contents of all material shipments upon arrival. Verify
quantities and correct finishes. NOTIFY EFCO IMMEDIATELY OF ANY
DISCREPANCIES OR DAMAGE WHICH MAY HAVE OCCURRED.
H. Throughout these instructions the term SEALANT will appear. For the
purpose of these instructions, sealant is to be defined as follows:
SEALANT - A weather resistant, gunnable, liquid filler which when dry
provides a resilient, flexible air and water seal between similar and
dissimilar materials. All sealant must meet FEDERAL SPECIFICATIONS
TT-S-001543A, TT-S-00230C, and ASTM C 290.
NOTE:
Do not assume compatibility of materials in a glazing system already
exists. Chemical reactions from physical contact of incompatible materials
can adversely affect one or all of the glass or glazing materials. It is
strongly advised that sealant manufacturers conduct compatibility and
adhesion tests in their laboratories using each exact component of the
glazing system (i.e., glass product, structural silicone, aluminum with
painted or anodized finish, setting blocks, glazing tapes, etc.) and
document compatibility or other findings in written test reports. All
frame surfaces should be clean, dry, dust free, and frost free. If a primer
is required, it must be applied to clean surfaces. All perimeter substrate
should be cleaned and properly treated to receive sealant. It is the
responsibility of the installer to follow these guidelines.
TOOLS NEEDED:
1. Dead blow hammer, part #HM46
2. Deglazing tool, part #HM47
3. Brush
4. Cutting tool, do not use box or craft knives.
5. Needle nose pliers
6. Metal spatula

SECTION II: VERTICAL FRAME INSTALLATION
STEP #1 INSTALL VERTICAL MULLIONS AND ANCHORS
Prestage necessary tools and materials in the work area. Prepare all head,
sill, and jamb substrates by cleaning and setting all flashings and/or
membrane seals as specified by the project shop drawings.
Insert the mullion and/or head anchor, as specified by the project
shop drawings, into the end of tubular mullions. For splice joints and floor
anchors at multispan conditions, refer to steps #2 and #3 on pages 4
and 5.

fillers, start at one end and
work into place along the
remaining length.

SECTION II: VERTICAL FRAME INSTALLATION
STEP #2 APPLY MIDSPAN FLOOR ANCHORS
Attach the midspan floor anchors to the mullions with temporary alignment
screws. Set the vertical mullion in place, plumb and true. Make permanent
attachment of base anchors, head anchors, and midspan floor anchors to
the building structure as specified in the approved project shop drawings.
After completing permanent anchorage, remove all temporary alignment
screws and fasteners. Multiple runs of vertical mullions can be set in
advance of erecting the horizontal members if desired, or the horizontals can
be filled in as additional mullions are erected.
NOTE: On long runs, check overall frame dimensions at every fifth opening
to avoid dimensional build-up.
