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.

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

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.

Note: When attaching pocket 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.

POSITION THE MULLION PLUMB AND TRUE. PERMANENTLY ATTACH THE ANCHOR TO THE STRUCTURE PER PROJECT SHOP DRAWINGS.
