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 (regarding interior temperature, 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 likely to occur:
1. Bridging the 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 thermal breaks of one or all products involved

Section 1. General Notes
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 inclu de
specific details for the project. Shop drawings govern when conflicting information exists in the assembly an d
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 only some of the 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.
D. PERIMETER CONDITIONS - Verify that all job site co nditions 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 area in
question.
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. It is the resp onsibility 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 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.

Section 3A. Screw Spline Fabrication
The screw spline system is a fabrication and erection method that permits the preassembly of single units in the
shop or at the job site. These units are then erected by mating the male mullion of one unit to its counterpart female
mullion of the adjoining unit.
Notes:
1. When an entrance is required, shear block joinery must be used to attach the side lite horizontals.
2. Due to the screw tensions required for correct installation, it will be necessary to ‘wax’ the frame assembly screws to
prevent galling and breaking.
Fabrication Steps:
1. Measure the opening to determine the cut lengths of the frame components.
Allow a minimum 1/4” clearance at head and jambs and 3/4” clearance at the sill for shims and caulking.
Allow extra clearances, if necessary, to accommodate building tolerances and building movement.
2. Cut the vertical to frame size.
Verticals must run through.
If the opening has an entrance, see the appropriate frame and door fabrication installation sheets.
Door jambs run to the floor and are cut longer than other verticals.
3. Drill holes for assembly screws on vertical members per one of the following methods.
Drill jigs are available. (See Page #7)
Layout holes per figures #1,2, or 3 and drill.
Use punch press with appropriate die set.
4. Cut horizontal members to day lite openings. (Between vertical members) Also cut the horizontal glass stops to day
lite opening minus 1/32”. (DLO - 1/32”)
