Alu Lamella Mat mats are designed for thermal, acoustic and anti-condensation insulation in ventilation and air-conditioning ducts of any cross-section, e.g. rectangular, circular, as well as for insulating low-temperature pipes, pipelines, small tanks in, oval surfaces, finishing fittings, etc. they are characterized by a perpendicular arrangement of fibers for the lining made of reinforced aluminum foil, thanks to which they are strong and elastic and do not change their original thickness at bends and corners.
