Product description
Besides thermal insulation, HVAC metal ductworks often require acoustic insulation to prevent noise transmission and improve comfort. Special insulation such as KCL slabs or blankets are fixed to the internal walls for effective reduce the noise.
KCL Premium is used to line air conditioning ducts, walls and/or ceilings of acoustically sensitive areas to provide efficient sound insulation for any variety of structure, and/or sensitive facilities as home theaters or studios, curtain walls.
KCL Premium is a highly efficient acoustic material, produced from strong resilient glass fibers firmly bounded together with a thermosetting resin. KCL Premium is faced with a black, strong, durable, dimensionally stable woven glass fabric. KCL Premium is especially designed to provide exceptional sound absorption to acoustically sensitive environments and/or equipment as air-conditioning equipment, auditoriums, theatres, studios, acoustical building assemblies, curtain walls
