5.8 STEEL BUILDING WALL INSULATION
There are many types of insulation installed in pre-engineered steel buildings. However, fiberglass blanket insulation is the most common type used, and these instructions pertain to this type only. One side of the blanket insulation should have a vapor barrier that must face the inside of the steel building regardless of whether the insulation is for heating or cooling.

WALL INSULATION INSTALLATION
Cut the insulation to length allowing an additional 6” or more to facilitate handling. The wall panel can be used as a guide.
NOTE:
The insulation must compress between the girt and the wall during installation. Insulation too thick or dense to compress adequately will induce waviness or oil canning in certain types of wall panels.
The first run of wall insulation should be installed so that its forward edge is just ahead of the leading edge of the wall panel. The most widely used procedure is to use a 4 ft. starter run, then switch to 3 ft. or 6 ft. runs. This keeps the forward edge of the insulation 1 ft. ahead of the wall panel for joining the next blanket.
NOTE:
Do not allow the insulation to wick moisture from the floor.
NOTE:
General steel Insulation has no load bearing strength. Do not lean or prop material against wall insulation. Observe all proper safety procedures when handling fiberglass insulation, such as dust masks, gloves, and long sleeved shirts, to minimize contact with the insulation fibers. Safety first!
