Fiberglass insulation is one of the most common materials used to insulate homes and buildings. It’s made from extremely fine glass fibers that trap air, helping to slow the transfer of heat, which keeps indoor spaces warmer in winter and cooler in summer.
Fiberglass can be placed in unfinished walls, floors, and ceilings. It is fitted between studs, joists, and beams. Fiberglass is made to slow the spread of heat and cold in both residential and commercial insulation projects
