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 (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 likel y 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 ther mal breaks

of one or all products involved

Note: Assembly Instructions are provided as a supplement, and should be used in conjunction with

the approved shop drawings.

Section 1 - General Notes And Guidelines

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 include specific details for the project. Shop drawings govern when conflicting information exists in the assembly and 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 many 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.

C. ERECTION SEQUENCE - The sequence of erection should be

coordinated with the project general contractor to prevent delays and minimize the risk of material damage. Note: When preset anchors are required, coordinate and supervise anchor and insert placement with the general contractor including insert layout drawings, where required .

Manufacturing, assembly, glazing, and shipment of the preglazed units must be carefully coordinated with the general contractor to ensure a continuous and sustained flow of materials to the appropriate areas of the project to meet the project completion schedule.

D. PERIMETER CONDITIONS - 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. 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.

This system is designed and has been tested to utilize silicone sealants at all internal joineries, i.e., joint plugs, gasket intersections, etc. It is the responsibility 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

EFCO 2009 Page 5

Series 8700 / 8800 Unitized Curtain Wall Assembly Instructions - Volume 1

Section 1 - General Notes And Guidelines

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. Maintain caulk joints as shown in the approved shop drawings. A 1” minimum joint is required at the head and jamb condition to accommodate installation, building movements, and thermal expansion and contraction.

H. STRUCTURAL SEALANT JOINTS - The maximum allowable size of the

glass lite is controlled by the width and depth of the structural silicone joint combined with the specified design wind load (PSF or Pa). The stress on the structural silicone must not exceed 20 PSI (137 KPa) for a 6:1 safety factor. In order to determine the structural silicone sealant contact width or bite which adheres the glass to the frame, a calculation must be performed on a job by job basis. The formula which determines the sealant width is based on using a trapezoidal load distribution rule. This formula is expressed as follows:

Structural Sealant = 0.5 x Short Span (ft) x Wind load (lb/ft²) Bite or Contact Width (in) Sealant Design Strength (=20 lb/in²) x 12 in/ft

Example: Lite size is 48” x 60” and wind load for the project is 60 psf.

Structural Sealant = 0.5 x 4’ x 60 psf

or 120 or .500”

Bite or Contact Width (in) 20 x 12 240

Sealant manufacturers, as a general rule, specify the structural sealant depth (glue line) to be one half of the contact width for a 2:1 width to height ratio. The glue line should not exceed 3/8” thick nor be less than 1/4” thick. The standard joint size for Series 8800 is 1/2” x 1/4”. Note: Weather seals must be applied a minimum of four hours after the application of the SSG sealant joint to allow for proper cure time.

I APPROVED SOLVENT OR CLEANER - Degreasing solvents, such as

methyl ethyl ketone (MEK), toluene, xylene, acetone and mineral spirits can been used to remove oils or other surface contaminants, but may leave a residue film on the cleaned surfaces, which must be removed. A solution

of fifty percent Isopropyl alcohol and fifty percent water is recommended for

the final cleaning and preparation of substrates for sealant application. Refer to the sealant manufacturer’s application instructions, ASTM C 1193 09, project specifications, and local environmental regulations for requirements.

SSG sealant joint has cured for at least 4 hours.)

J. SECONDARY SEALANT JOINT DESIGN - The design of the secondary

sealant joint is based on the 50:50 load sharing principal where the I.G. unit is comprised of two symmetrical lites of glass. The secondary sealant joint that adheres the two lites of glass together only carries half the wind load applied to the I.G. unit. Since the load is halved, the secondary sealant contact width is half that of the SSG joint. Using the example earlier for the 1/2” x 1/4” SSG joint, the secondary sealant contact width for the I.G. unit in the example is 1/4”.

Edge deletion is required on the coated surface (#2 or #3) for hard or soft coated glazing products.
