GENERAL INFORMATION CONT.
CLEANING MATERIALS:
Cement, plaster, terrazzo, alkaline and acid based materials used to clean masonry are v ery harmful to
finishes and should be removed with water and a mild soap immediately or permanent staining will
occur. A spot test is recommended before any cleaning agent is used.
EXPANSION JOINTS:
Expansion joints and perimeter seals shown in these in structions 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
unrestrained lengt h of aluminum extrusion can expand or contract 3/32 of an inch over a 50 degree
Fahrenheit change. Any movement potential should be accounted for at time of the installation.
THERMAL IMPROVEMENT SUGGESTIONS:
To maintain or improve your wall installation, the following items should be considered:
1. Blinds or drapes prevent warm air from washing the window.
2. Warm air ventilators too far from window will not adequately wash the window with air to
prevent condensation.
3. In extreme conditions, the fan of the heating systems should not cycle on and off, but run
continuously.
4. 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 temperature
and reducing humidity will usually solve this problem.
5. 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 th e window wall can reduce or
eliminate this temporary condition.
FABRICATION SUGGESTIONS:
Oldcastle BuildingEnvelope recommends the use of our EZ Punch tooling for faster
and more accurate fabrication of wall systems. If hand fabricating the
mullions; drill fixtures are available to improve accuracy. Fabrication instructions
for use of these drill fixtures are described within this manual on pages 35
through 39.
