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 recommend ed 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 lik ely to occur:

1. Bridging system thermal break with non-thermally broken metal flashin g 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

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 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 area in question.

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.

EFCO 2009 Page 3

Series 8700 / 8800 Unitized Curtain Wall Installation Instructions

Section 1: General Notes And Guidelines

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 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 4’0” x 5’0” 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” thickness nor be less than 1/4” thick. The standard joint size for Series 8000 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. 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.

Section 3 - Static Starter Sill Preparation and Installation

Projects will be produced by EFCO in one of three ways: 1) As a stock length product whe re all fabrication, assembly, and glazing will be performed by the customer, or: 2) Prefabricated “knock down” where EFCO fabricates the materials, and the customer performs the assembly, and glazing, or:

3) EFCO will provide a completely fabricated, assembled and glazed product. The materials shown here in the installation instructions may be received in the field with varying degrees of shop assembly, with some items shop installed, and other items to be field installed. Certain assembly and install ation procedures shown and described in this document may be performed in the shop or the field at the discretion of the assembler.

1. Preparation of the Static Starter Sill: a. The static starter sill may have an end dam pre-attached and sealed at the jamb condition. Ensure that the end dam is properly applied and sealed

to the starter sill as described below. This is a critical seal and the joint must be carefully tooled to create a watertight seal. See Figures 1, 2, and 3.

b. The starter sill may have gaskets (WC19 and LC23) pre-applied. The LC23 is cut to the length of the starter sill while the WC19 will be

approximately 6” to 8” longer than the starter sill. Do not cut off excess WC19. The excess gasket will be slid into the adjacent starter sill during installation.

c. Plug the end of the tubular section of the starter sill at the jambs and corner conditions by recessing backer rod at least 1/4” into the end of the tube.

Fill the voids in the tube and between the thermal struts with sealant and tool smooth. Intermediate splice locations incorporate an int ernal splice sleeve and will be covered later in this section.

Clean all sealant contact surfaces using an approved solvent or cleaner of all oils and other contaminants. The sealant manufacturer’s preparation and application instructions should be followed exactly. If sealant primer is required, apply it per the primer/sealant manufacturer’s instructions.

d. A gutter base anchor (FM01 or FM02) is required at each intermediate vertical and jamb. Two are required at corner mullion conditions. The

anchors are used to transfer wind load reactions from the verticals into the anchoring system. Before installation of the static starter sill, slide the appropriate number of gutter base anchors into each section of starter sill. See Figures 4 and 5.

e. Slide the gutter base anchors into final position after the starter sill anchor bolts have been applied.

2. Verify that all job site conditions and accompanying substrates receiving the installation are in tolerance and are in accordance with the contract documents.

3. Pre-cleaning the substrates where the caulk joints will be applied later may be advisable prior to setting the starter sill. Final cleaning and sealant primer

application where required should be performed only immediately before caulk joint sealant applicatio n.

4. Use established bench marks to ensure the accuracy of the starter sill location. Precise measurements and coordination with regard to established bench

marks are critical to ensure that the starter sills are installed in the correct location. Improperly installed, or miss-located starter sill s will cause significant problems for the remainder of the erection process.

5. Starting at the jamb, place the starter sill into the opening hard on the condition in the final position, excluding elevation. Match drill the substrates at the

anchor locations and apply the anchors allowing for shim space under the starter sill. Refer to the approved shop drawi ngs for type, size, and specific anch or details. Shim the starter sill to the proper elevation height making sure the starter sill is level. The shims used must be full bearing shims. The shims must fully support the entire load bearing surface of the starter sill at each anchor location. Refer to the project structural calculation package and final approved shop drawings for detailed information.

6. EFCO recommends minimum of a 1/2” caulk joint between the starter sill and the condition.

When applying anchor bolts to the starter sill, pre-fabricated serrated washers (17D3) must be used. The serrate d wa shers will lock the starter sill into position when the anchor bolt is tightened. See Figures 7, 8 and 9. After verifying the final position of the starter sill, secure the anchor bolts as required.

Put a temporary shim between the end dam and the condition to protect the end dam during unit installation. The required shim thickness will vary due to field tolerances and project specific joint size requirements, but a minimum of 1/2” is reco mmended. Remove the shim after unit installation.

10. Plug the ends of the dynamic starter sill gutter at jamb and corner conditions by recessing backer rod at least 1/4” into the end of the front part of the gutter.

Apply sealant to fill the void at the ends and tool the sealant flush. See Figures 28 and 29. Intermediate splice locations incorporate an internal splice sleeve and will be covered later in this section.

11. When setting the starter sill gutter onto the gutter base, align the race ways on the bottom of the gutter with WC16 gasket in the gutter base. See Figure 32.

12. Attach the gutter to the gutter base with SPZ1 fasteners to secure it in place. See Figure 30.

13.

Immediately tool the sealant at the end dam to gutter joint. Apply additional sealant as necessary to seal all around the end of the gutter as shown. The sealant must be thoroughly tooled at this joint to create a water tight seal. See Figures 31 and 32.

14. Set the next series of sections of starter sill base into the opening, butting together the sections at the corners, and allowing a nominal sized space between

the sections at the intermediate splice locations. Refer to the final approved shop drawings for exact joint size. Once the starter sill bases are level, true and plume relative to established benchmarks, anchor to the substrate as previously described.

15. Using an approved solvent or cleaner, clean the sealant contact surfaces of the starter sill depicted below of all oils and other contaminants. The

sealant manufacturer’s preparation and application instructions should be followed exactly. If sealant primer is required, apply it per the primer/ sealant manufacturer’s instructions.

16. Slide the next section of starter sill gutter onto the starter sill base while threading WC19 gasket into the adjacent gasket reglet as shown.

17. Butt the starter sills gutters together at the mitered corner and secure the unattached gutter to the starter sill base with SPZ1 fasteners.

18. Slide apart the WC19 gaskets to create a gap between the two gaskets. Apply a small amount of sealant to the end of one of the gaskets. See Figure 33.

19. Butt the two WC19 gaskets back together tightly, and remove any excess sealant.

20. Apply sealant into the void at the gap in the corner as shown. See Figure 34. Sealant should fill the void completely and must be tooled flush all around,

including the underside of the starter sill gutter. Remove excess sealant to form a neat caulk joint in the exposed areas.

Thread the WC19 gasket in

the starter sill. Then apply

sealant to the end to create

a butt seal between the two

WC19 gaskets.
