Quick Detail:
Leadsun Glass Wool Board is manufactured using advanced centrifugal technology and environmentally friendly thermosetting resin binders. Composed of ultra-fine glass fibers with diameters of only a few microns, it contains numerous tiny air pockets that provide exceptional thermal insulation, sound absorption, and fire safety properties. This makes it an ideal insulation material for a wide range of construction and industrial applications.
