Semirigid form of Fiberglas insulation conies off conveyor a t any desired thickness a n d density· Binding agent holds fibers down against natural resiliency, y e t leaves mass flexible enough for fitting to irregular surfaces. This is used t o insulate refrigerators, buildings, and heated surfaces up to 900° F . Left. Fiberglas draperies hang gracefully, are fireand moistureproof, and will n o t fade. Left below. By using suitable binding agents, Fiberglas insulating wool is formed o n mandrels t o give a lightweight pipe insulation for temperatures from below zero to 1100° F. Below. Wings covered with glass cloth were established as practical in the first actual test flight of this Taylorcraft. The Fiberglas cannot be fired by a cigaret lighter flame.
