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 likely 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 thermal

breaks of one or all products involved

Section I: General Notes & 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 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 with

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 anchors are required, coordinate and supervise
anchor placement with the general contractor.

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. Prevent all aluminum from coming in direct contact with masonry or dissimilar

materials by means of an appropriate primer.

Series 5600 Slope Glazed Curtain Wall Installation Instructions

Section I: General Notes & Guidelines

F. Follow EFCO framing installation and glazing instructions.
G. Verify contents of all material shipments received upon arrival. Verify quantity

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, 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 where 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.

Anchoring surfaces of perimeter construction must be level and
plumb within the adjustable limits of the head, jamb, and sill
framing.

PVC Isolator and Gasket Application

A.) Insert appropriate gasket and isolator into rafter and purlins as shown.

(Ref. Figs. 13A & 13B)

B.) Gaskets can become somewhat deformed during storage in cartons. They should

be removed from cartons and / or rolls several hours prior to use, lay flat or hang
so as to allow for recovery of correct shape. Temperatures should be at least 50
degree to allow for recovery.

C.) * DO NOT STRETCH GASKETS out of shape. Cut approximately 1/8” longer per

foot and work from ends to the center. Then trim off excess. (Ref. Fig. 14)
