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 relative 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 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 likel y 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 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 ther mal breaks
of one or all products involved
Note: Assembly Instructions are provided as a supplement, and should be used in conjunction with
the approved shop drawings.

Series 8700 / 8800 Unitized Curtain Wall Assembly Instructions - Volume 1
Section 1 - General Notes And Guidelines
HANDLING / STORING / PROTECTING ALUMINUM
The following guidelines are recommended to ensure 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 immediately
removed with soap and water. Under no circumstances should these
materials be allowed to dry or permanent staining may occur.
GENERAL GUIDELINES
The following practices are recommended for all installations:
A. REVIEW CONTRACT DOCUMENTS – Become thoroughly familiar with
the project. Check shop drawings, installation instructions, architectural
drawings and shipping lists. The shop drawings take precedence and
include specific details for the project. Shop drawings govern when
conflicting information exists in the assembly and installation instructions.
Note any field verified notes on the shop drawings prior to installing.
EFCO assembly and installation instructions are general in nature and
cover many conditions.
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. ERECTION SEQUENCE - The sequence of erection should be
coordinated with the project general contractor to prevent delays and
minimize the risk of material damage. Note: When preset anchors are
required, coordinate and supervise anchor and insert placement with the
general contractor including insert layout drawings, where required .
Manufacturing, assembly, glazing, and shipment of the preglazed units
must be carefully coordinated with the general contractor to ensure a
continuous and sustained flow of materials to the appropriate areas of the
project to meet the project completion schedule.
D. PERIMETER CONDITIONS - 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. ISOLATION OF ALUMINUM - Prevent all aluminum from coming in direct
contact with masonry or dissimilar materials by means of an appropriate
primer. Typical slab anchors may be set directly onto concrete surfaces in
a block-out pocket at the edge of the slab. The block-out pocket is later
filled in with grout thereby covering the slab anchor. In such cases, a
heavy coat of zinc chromate or bituminous paint must be pre-applied to
the slab anchor.
F. SHIPMENT VERIFICATION - Verify contents of all material shipments
received upon their arrival. Verify quantity and correct finishes. Notify
EFCO immediately of any discrepancies or damage that may have
occurred.
G. SEALANT - All sealant must meet ASTM C 920, CLASS 50. 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 min.) air and
water seal between similar and dissimilar materials.
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. All sealants and primers must be applied
according to the sealant manufacturers instructions and
recommendations.
This system is designed and has been tested to utilize silicone sealants at
all internal joineries, i.e., joint plugs, gasket intersections, etc. It is the
responsibility of the glazing contractor to submit a statement from
the sealant manufacturer indicating that glass and glazing materials have
been tested for compatibility and adhesion with glazing sealants, and
interpreting test results relative to material performance, including
EFCO 2009 Page 5
Page 6
Series 8700 / 8800 Unitized Curtain Wall Assembly Instructions - Volume 1
Section 1 - General Notes And Guidelines
recommendations for primers and substrate preparation required to obtain
adhesion. The chemical compatibility of all glazing materials and framing
sealants with each other and with like materials used in glass fabrication
must be established. Maintain caulk joints as shown in the approved shop
drawings. A 1” minimum joint is required at the head and jamb condition to
accommodate installation, building movements, and thermal expansion and
contraction.
H. STRUCTURAL SEALANT JOINTS - The maximum allowable size of the
glass lite is controlled by the width and depth of the structural silicone joint
combined with the specified design wind load (PSF or Pa). The stress on
the structural silicone must not exceed 20 PSI (137 KPa) for a 6:1 safety
factor.
In order to determine the structural silicone sealant contact width or bite
which adheres the glass to the frame, a calculation must be performed on a
job by job basis. The formula which determines the sealant width is based
on using a trapezoidal load distribution rule. This formula is expressed as
follows:
Structural Sealant = 0.5 x Short Span (ft) x Wind load (lb/ft²)
Bite or Contact Width (in) Sealant Design Strength (=20 lb/in²) x 12 in/ft
Example: Lite size is 48” x 60” and wind load for the project is 60 psf.
Structural Sealant = 0.5 x 4’ x 60 psf
or 120 or .500”
Bite or Contact Width (in) 20 x 12 240
Sealant manufacturers, as a general rule, specify the structural sealant
depth (glue line) to be one half of the contact width for a 2:1 width to height
ratio. The glue line should not exceed 3/8” thick nor be less than 1/4” thick.
The standard joint size for Series 8800 is 1/2” x 1/4”. Note: Weather seals
must be applied a minimum of four hours after the application of the SSG
sealant joint to allow for proper cure time.
I APPROVED SOLVENT OR CLEANER - Degreasing solvents, such as
methyl ethyl ketone (MEK), toluene, xylene, acetone and mineral spirits
can been used to remove oils or other surface contaminants, but may leave
a residue film on the cleaned surfaces, which must be removed. A solution
of fifty percent Isopropyl alcohol and fifty percent water is recommended for
the final cleaning and preparation of substrates for sealant application.
Refer to the sealant manufacturer’s application instructions, ASTM C 1193 09, project specifications, and local environmental regulations for
requirements.

J. SECONDARY SEALANT JOINT DESIGN - The design of the secondary
sealant joint is based on the 50:50 load sharing principal where the I.G. unit
is comprised of two symmetrical lites of glass. The secondary sealant joint
that adheres the two lites of glass together only carries half the wind load
applied to the I.G. unit. Since the load is halved, the secondary sealant
contact width is half that of the SSG joint. Using the example earlier for the
1/2” x 1/4” SSG joint, the secondary sealant contact width for the I.G. unit in
the example is 1/4”.
Edge deletion is required on the coated surface (#2 or #3) for hard or soft
coated glazing products.

Section 3 - Unit Frame Assembly : A. Mullion Subassembly
1. Slide WC21 gasket into the male vertical mullion. Exercise care to avoid stretching the gasket. The gasket should be crowded when inserted into the gasket
reglet and overhang each end of the mullion at least 1”.
2. The mullion gasket reglet must be carefully crimped at each end, and along the length in multiple locations (24” on centers), to retain the gasket and keep it
from slipping at the ends (see Figure 3).

3. Identify the appropriate frame gasket for the intended application (refer to the parts list cross reference on the following page for more information).
4. Clean the mullion surfaces that will contact the frame pads. Using an approved solvent or cleaner, clean the surfaces of all oils and other
contaminants.
5. Remove the liner from the frame gasket and apply it to the matching surface of the mullion ensuring the holes and edges align as required. (There may be
excess holes in the frame gasket without a corresponding hole in the mullion as the gaskets are designed for multiple application locations.)
6. Smooth out the frame gasket onto the mullion surface by forcing out any remaining air bubbles.
7. Tear the excess gasket material at the serrations in areas where the gasket overhangs as shown in Figure 6 and 7.

1. Assemble the framing facing upward (glazing side up). Use saw horses or assembly tables durin g assembly. Provisions to protect the finished surfaces of
the material must be employed on the table or saw horses.
2. Check to ensure the frame gaskets are intact and properly applied.
3. Fasten the ends of all of the horizontals, first to one jamb, with SFQ5 (1/4”-14 X 1 1/2” HW-SMS 18-8), and then to the remaining jamb. Torque the screws
tight enough to fully compress the frame gaskets, but do not over tighten. Wax applied to the threads of the fasteners is recommended for lubrication to assist
with driving in the screws. Cap seal the fastener heads with sealant.
