Interior membranes from SHEERFILL® are translucent, non-combustible, porous composites based on fiberglass and polytetrafluoroethylene (PTFE). When used as a liner in SHEERFILL Architectural Membrane systems, Fabrasorb acoustical membrane significantly reduces interior noise levels. Virtually invisible to the untrained eye, Fabrasorb appears as an integral part of the roof itself. Ideal for sports complexes and industrial facilities, Fabrasorb allows diffused natural daylight in, while minimizing acoustical disturbance. In addition to serving as a sound attenuator, Fabrasorb membrane also improves the thermal characteristics of fabric roof systems. By providing an extra layer of insulation, Fabrasorb helps keep inside temperatures cool and comfortable, even under the sweltering heat of direct sunlight. Fabrasorb material from SHEERFILL acts as a functional and attractive focal point, making a quiet statement for years to come.
