Originally, Fiberglas was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.
Inflow enters directly through opening parts of the sewer system such as vents and manhole covers. In normal operations, small amounts of infiltration and inflow are expected. When those amounts are excessive, they could cause sewer system to have surcharges, higher operational costs to transport and treat higher than design wastewater volumes ...
When necessary, a double walled duct is used. This will usually have an inner perforated liner, then a 1–2" (2.5-5 cm) layer of fiberglass insulation contained inside an outer solid pipe. Rectangular ductwork commonly is fabricated to suit by specialized metal shops. For ease of handling, it most often comes in 4' (120 cm) sections (or joints).
