Minimiz ing Condensation

NOTE: Please reference EFCO's "Underst andi ng Condensat i on" broc hure whi ch c an 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 exc ess i ve c ondensat i on 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 installation methods. Please contact
EFCO representative for informat i on on EFCO's Thermal Analysis Services.
Many current install ation 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 hum idity level s 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 t he shop drawing stage that result in bridging thermal breaks of one or all products
involved.

SECTION I - GENERAL NOTES

EFCO Series 960 Wall is a thermal wall system with a 1 3/4" face dimension
and has system depth dimensions from 2 3/4" to 8 1/8". The system is
exterior glazed with either 1/4" or 1" dry glazing. Entrance doors are an
engineered part of the system.

1)

Check the shop drawings, installation instructions, and the glazing
instructions to become thoroughly familiar with the project. The shop
drawings take precedence and include specific details for the project.
The installation instructions are of a general nature and cover the most
common conditions.

Check all materials upon arrival and be sure you have everything required

2)

to begin installation.
(See Section II "PARTS IDENTIFICATION")

All work should start from bench marks and/or column center lines as

3)

established by the architectural drawings and the general contractor.
Check construction for compliance with the contract documents.

4)

Sealants must be compatible with all surfaces. Consult with the sealant
manufacturer for recommendations regarding compatibility and adhesion.

All materials are to be installed plumb, level, and true.

5)

6)

Protect aluminum materials after erection. Cement, plaster, alkaline
solutions, and acid based materials can be harmful to the finish.

7)

Clean all finished aluminum surfaces with a mild detergent and water.
No abrasive agent should be used.

SECTION III - SCREW SPLINE FABRICATION

The screw spline system is a fabrication and erection method that permits
the preassembly of single units in the shop or at the job site. These
units are then erected by mating the male mullion with the female mullion
counterparts.

When an entrance is required, shear block joinery must be used to attach
the side lite horizontals to the immediate door frame. The other side of
the side lite will be fabricated for screw spline joinery as usual.

NOTE:

DUE TO THE SCREW TENSIONS REQUIRED FOR CORRECT
INSTALLATION, IT WILL BE NECESSARY TO ’WAX’ THE FRAME
ASSEMBLY SCREWS TO PREVENT GALLING AND BREAKAGE.

STEP 1)

NOTE: Allow a minimum 1/

NOTE: Allow extra clearances, if necessary, to accommodate building

STEP 2)

NOTE: Verticals must run through. If the opening has an entrance,

NOTE: Door jambs run to the floor and are cut longer than other verticals.

Measure the opening to determine the cut length of the frame
components.

2" shim and caulk space around the perimeter.

tolerances.

Cut the verticals and vertical face caps to the frame size.
see the appropriate frame and door fabrication and

installation sheets.

STEP 3)

STEP 4)

Drill holes for the assembly screws on the vertical members.

See the drilling template on page 19 or the drill jig guide on
page 20.

Cut the horizontal members to the day lite openings (between the
vertical mullions).
Cut the horizontal face caps to day lite openings minus 1/16".

SECTION IV - SHEAR BLOCK FABRICATION

STEP 1)

Measure the opening to determine the cut length of the frame
components.

NOTE: Allow a minimum 1/2" shim and caulk space around the perimeter.
NOTE: Allow extra clearances, if necessary, to accommodate building

tolerances.

STEP 2)

Cut the verticals and vertical face caps to the frame size.

NOTE: Verticals must run through. If the opening has an entrance, see

PAGE 27

the appropriate frame and door fabrication and installation sheets.

NOTE: Door jambs run to the floor and are cut longer than other verticals.

STEP 3)

Drill mounting holes for the shear blocks on the vertical members.

See the drilling template on page 28 or the drill jig guide on page

29. Also refer to pages 30 through 32 for drilling information.

STEP 4)

Cut the horizontal members to the daylite openings (between the
vertical mullions).
Cut the horizontal face caps to daylite openings minus 1/16".
(D.L.O. - 1/16")

STEP 5)

Drill the holes in the horizontals for attachment to the shear blocks.

STEP 1)

STEP 2)

STEP 3)

Cut the S.S.G. mullion to frame D.L.O. and screw spline attach the
mullion to the perimeter members using the S108 screw spline screws.

See page 59.

Set the assembled unit in place on the sill flashing, and anchor
as directed previously. Refer to Section VIII.

Install the butt glaze spacer tape to the butt glaze mullion as shown in
Fig. #63 on page 58. The spacer tape will run the full length of the

vertical butt glaze mullion. Peel back ONLY 2" of the exterior film of
the spacer tape at the head or the sill. DO NOT remove all of the exterior

film until the glass unit is installed and positioned correctly.
Install the setting chairs at 1/4 points in the sill members. Set the glass

units in place and install (2) glazing clips side by side 3" from the vertical
mullion and a single clip at 9" on center from the pair, at the head and sill.

Be sure the ’ears’ of the clips are toward the glass unit at the head and sill,
and jambs. Also, it must be facing up at the horizontal intermediates.

Refer to page 61.

STEP 4)

NOTE:

STEP 5)

STEP 6)

Set the glass unit and position it with the correct glass bite all around.

Review the ’temporary’ glazing procedure presented on page 62, and
apply these steps accordingly, if required. If incorporating this procedure,
set the temporary glazing covers, leaving access to the vertical glass edges
for the application of the structural silicone at the vertical butt glaze mullion.

Peel off the exterior film of the butt glaze spacer tape and press the glass
onto the spacer tape. Install the 12" temporary cover pieces at the head
and sill to hold the glass units while the interior silicone is applied.

Refer to page 59.
Repeat the previous steps at other butt glaze mullions in the elevation.

The next day remove the temporary covers and replace any clips that
are broken in this process.

Install the exterior structural silicone to the glass joint. Clean any excess
sealant from the glass surface, presenting a clean professional
appearance. This step will also require an overnight cure for the silicone.

Install the W115 bulb gasket in the full length covers, allowing
approximately 2% extra per length, to minimize gasket shrinkage.
Install the full length covers at the head, sill, and jambs.

opening, locate and install the isolator clips as shown in figure # 68 above
The isolator clips are located: side by side pairs, 3" from each vertical
or horizontal intersection and single clips 9" on center.

NOTE:

960 WALL

The isolator clips alone are not suitable for temporary glazing.

At no time should set glass or panels be left unattended with only the
isolator clips holding the units in place. Prompt installation of the snap
covers is required to obtain the full structural capability of the system.
If temporary glazing is required, please refer to the Temporary Glazing
instructions on pages 62 and 63.

If temporary glazing is required, EFCO recommends the use of (2) 12" lengths
of the snap cover and (3) clips min. per cover piece, snapped in place as shown
above, at the corners of the horizontals and verticals to retain the glass until the
full length covers can be installed. This temporary clipping should be installed at

every corner of each daylight opening resulting in 8 pieces of snap cover per
daylight opening. This is a temporary application only and is not to be used for
a structural application. This system will not meet structural performances until

full length covers and the required quantity of clips have been installed.
