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 lint els 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.

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.

A.) Attach anchors to mullions with temporary alignment screws as shown below. B.) Install the vertical mullions in position and attach anchors to the building structure

per the “APPROVED” shop drawings.

fter final alignment of mullion, align drill mullion in best hole location. Note that the hole must be a minimum of 1” from the back of the mullion to clear any steel reinforcement required for the job.

Use #12 X 1” Tek screw for alignment only. The screw must be removed after installation of the thru bolt at the wind load anchor to allow for thermal expansion and contraction.
