Why Glass Wool With Heat Insulation

Why glass wool with heat insulation

Because there are many and very thin glass fibers inside the glass wool products, the surface area is very huge, such as 12 kilograms of glass fibers with an average diameter of 5 microns, filled in 1 cubic space, and the surface area can reach 5000 square meters.

The volume of glass wool fiber accounts for only 0.6%, and the rest is air, which has great resistance to air flow, and air can hardly flow in it, so it loses the ability of convection heat transfer, and the static air insulation performance is extremely high strong, so that glass wool products have excellent thermal insulation properties.
