CHECK MATERIAL
Check glass dimensions for overall size as well as thickness. Oldcastle BuildingEnvelope cannot be held
responsible for gaskets that are not water tight due to extreme glass tolerances. The Reliance -IG SS curtain
wall system is designed to accommodate glass or panels measuring 1" and 1/4" in thickness (+/- 1/32").
Check all material upon arrival at job site for quality and to determine any shipping damage.
Using the contract documents, completely check the surrounding conditions that will receive your materials.
Notify the general contractor by letter of any discrepancies before proceeding with the work. Failure to do so
constitutes acceptance of work by other trades.
Check shop drawings, installation instructions, architectural drawings and shipping lists to become 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. Due to varying job
conditions all sealant must be approved by the sealant manufacturer to insure it will perform per the
conditions shown on the instructions and shop drawings. The sealant must be compatible with all surfaces in
which adhesion is required, including other sealant surfaces. Use primers where directed by sealant
manufacturer. Properly store sealant at the recommended termperatures and check sealant for remainder of
shelf life before using.
FIELD CONDITIONS
All material to be installed must be plumb, level and true. Aluminum to be placed in direct contact with
masonry or incompatible material should be isolated with a heavy coat of zinc chromate, bituminuous paint or
non-metallic material.
After sealant is set and a representative amount of the wall has been glazed (250 sq.ft. or more), perform a
water hose test in accordance with AAMA 501.2 specifications to check installation. On large projects the
hose test should be repeated during the glazing operation.
CLEANING MATERIALS
Cement, plaster terrazzo, alkaline and acid based materials used to clean masonry are very harmful to
finishes. Any residue should be removed with water and mild soap immediately or permanent staining will
occur. A spot test is recommended before any cleaning agent is used. Refer to the Architectural Finish
Guide in the Detail Catalog.
EXPANSION JOINTS
Expansion joints and perimeter joints shown in these instructions and in the shop drawings are shown at
nominal size. Actual dimensions may vary due to perimeter conditions and/or differences in metal
temperature between the time of fabrication and the time of installation. For example, a 12 foot unrestrained
length of aluminum can expand or contract 3/32" over a temperature change of 50 degrees F. Any
movement potential should be accounted for at the time of the installation.
SUGGESTIONS FOR IMPROVING SYSTEM THERMAL PERFORMANCE
To maintain or improve your wall installation the following items should be considered.
A. Blinds or drapes prevent warm air from adequately flowing over the window surface.
B. Warm air ventilators too far from the window will not adequately wash the window with air to
prevent condensation.
C. In extreme conditions the fan of the heating system should not cycle on and off, but should run
continuously.
D. Some heating systems have a water injection feature that can raise humidity levels. The higher
the humidity levels the more likely condensation or frost will form. Raising the temperatures and
reducing humidity will usually solve the problem.
E. On rare occasions an extremely cold storm may cause frost to appear on the glass framing. A
space heater and electric fan blowing along the plane of the window wall can reduce or eliminate
this temporary condition.
