Resin Bonded (RB) Glasswool Insulation is a high-performance thermal and acoustic insulation material made from fine, inorganic glass fibers bonded together with a thermo-setting resin. It is lightweight, flexible, and designed to trap air, offering excellent fire resistance, energy savings (20-30% reduction in HVAC costs), and sound absorption for commercial and residential applications. Rb glasswool thermal efficiency offers high R-values (up to 7, depending on thickness) to prevent heat transfer.
