Glass Fiber From Yellow Thermal Blanket Insulation
This insulation is from an attic of a home that experienced
a fire. Part of the home was severely damaged. The heat was
sufficient in the attic to darken the phenolic resin that held the blanket together.

Characteristic Features:
The smaller quantity of phenolic resin used to hold thermal blanket insultion together
is distributed
more easily when it has a low viscosity. Mineral fillers would interfer with that
distribution. As
a result, the resin is clear with few inclusion. The total amount of resin on the fibers
is also lower
than in the case of acoustic ceiling tiles or ventilation system soundboard, whose resin
systems contain
mineral fillers.
