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 and 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 the material off the ground. Protect ma-

terials 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 mate-

rial.

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 removed with soap and water before hard-

ening. Under no circumstances should these materials be allowed to dry or perma-

nent staining will occur.

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 installa-

tion 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 an-

chors are required, coordinate and supervise anchor placement with the

general contractor.

D. Verify that all job site conditions and accompanying substrates receiving the instal-

lation are in accordance with the contract documents. If deviations occur, notifica-

tion must be given IN WRITING to the general contractor and differences re-

solved before proceeding further with the installation in the questionable area.

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

terials by means of an appropriate primer.

II.

SECTION I: GENERAL NOTES and GUIDELINES

F.

Follow EFCO framing installation and glazing instructions.

G. 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.

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 Refer-

ence Standard 5C-1).

NOTE: All sealant must be compatible with all surfaces on which adhesion is re-

quired, 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 re-

ceive sealant.

This system is designed and has been tested to utilize butyl or silicone seal-

ants 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 manu-

facturer'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” mini-

mum 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.

Section V: PUNCHED OPENING & RIBBON WINDOWS

(Frame Opening & Frame Sealing)

Punched opening and ribbon window elevations are typically used for small openings or openings of

limited height where the frames can be partially assembled off-site, moved to the jobsite, and then

groups of frames are snapped together. This allows groups of frames to be set into the opening all at

one time. Custom extruded aluminum anchors are slid into the heads and sills during frame assembly.

This method of anchorage is limited due to certain structural limitations. Please consult with the

structural engineer responsible for the shop drawings for your project. This type of installation also

requires that there be no obstructions (such as floor slabs or columns) that prevent the frames from

being installed from the interior.

Section V: Vertical Splice Joints

STEP #1 LOCATE SPLICE JOINTS

A. Splice joints should occur at spandrel areas (if possible). Refer to the approved shop

drawings for actual locations.

B. Depending on job requirements, the mullion splice may be shop or field assembled in

the top of the lower mullion. The cover splice is attached to the bottom of the upper

mullion. Where head clearance is insufficient to allow the top mullion to be lifted over

the splice sleeves, retractable splices should be used. The splices are to be taped into

the bottom of the top mullion and dropped down to the stop screw in the mullion

below.

C. GENERAL NOTE: The following pages depict a splice joint of 1/2”. This will allow plus

or minus 1/4” of movement for each splice location. Thermal expansion and live

deflection requirements should be considered when determining the location and

quantities of splice joints. If the total amount of movement cannot be accommodated

locating splices at every other floor or alternatively at each floor, expansion

horizontals or some alternative method should be used. Contact EFCO for further

evaluation.

D. Refer to this section for pressure cover splice locations, mullion splice locations, and

sealing instructions.

E. Once a final check of expansion joint placement and mullion position is made, the final

match drilling of mullion through anchor holes may be completed.
