GENERAL INFORMATION CONT.
CLEANING MATERIALS:
Cement, plaster, terrazzo, alkaline and acid based materials used to clean
masonry are very harmful to finishes and should be removed with water and
a mild soap immediately or permanent staining will occur. A spot test is rec-
ommended before any cleaning agent is used.
EXPANSION JOINTS:
Expansion joints and perimeter seals shown in these instructions and in the
shop drawings are shown at normal size. Actual dimensions may vary due to
perimeter conditions and/or differences in metal temperature between the
time of fabrication and time of installation. For example, a 12 foot unre-
strained length of aluminum extrusion can expand or contract 3/32 of an inch
over a 50° F change. Any movement potential should be accounted for at the
time of the installation.
THERMAL IMPROVEMENT SUGGESTIONS:
To maintain or improve your wall installation, the following items should be
considered:
A. Blinds or drapes prevent warm air from washing the window.
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 level the more likely conden-
sation or frost will form. Raising the temperature and reducing the
humidity will usually solve the problem.
E. On rare occasions, an extremely cold storm may cause frost to appear
on the glass or framing. A space heater and electric fan blowing along
the plane of the window wall can reduce or eliminate this temporary
condition.
