Fiberglass insulation or glass wool is a man made vitreous fiber.
Fibreglass roof insulation.
It is made by pulling strands of glass into thin fibers.
Thermal efficiency is a u k.
Wet fiberglass insulation has no r value until it dries out unlike foam board or sprayed foam insulation which keeps its insulation properties even when wet.
Fibreglass consists of fibres of glass formed by heating it to a very high temperature and is then bound to form a material similar to wool.
