AFICO’s products are all energy saving, environmentally friendly, use even more recycled materials and contribute to the fight against global warming.
The AFICO Quiet Liner Board is a resilient, semi-rigid fibre insulation board engineered from fine, uniformly textured inorganic glass fibres bonded with a fire-retardant thermosetting resin. Free from coarse fibres and shot, it delivers consistent acoustic and thermal performance across its full thickness. The board is faced with a strong, dimensionally stable Black Woven Glass Fibre Fabric (WGF) that faces the airstream, resisting airflow erosion while maintaining sound absorption. It is chemically inert, mould-resistant, and fully compliant with international fire, thermal, and acoustic standards — making it a dependable choice for commercial, institutional, and industrial HVAC applications across the UAE and the wider GCC.
