Large-area insulation work needs a material that can be moved, cut, and laid without slowing down the crew. Glass wool blanket is a roll-type inorganic fiber material, so it is often easier to place over wide ceilings, metal roofs, equipment rooms, ducts, and vehicle-related spaces than rigid board products. The roll form is the main reason many installers keep asking for it on projects with long surfaces.
The glass wool blanket information in the supplied product file lists a width of 1100 mm, length of at least 4000 mm, thickness of at least 90 mm, and density of 32 kg/m³. It also shows hydrophobicity of ≥98%, moisture content of ≤1.0%, and thermal conductivity of ≤0.038 W/(m·K) at an average temperature of 25℃. These figures are useful when a project needs both insulation data and practical packing planning before goods leave the factory. From a manufacturer's view, glass wool blanket is not difficult to describe, but it is easy to order incorrectly if the use area is unclear.
