Glass Fiber Duct Insulation, Pink Wrap
This is glass fiber from a flexible duct extention connected to a diffuser in an HVAC system. Much of the glass
fiber in this image is free of obvious resin. It can be identified as glass fiber from thermal blankets by the
variety of diameters, presence of bent fibers, and other artifacts characteristic of glass wools.
