Model LAG 'FR' Acoustical Pipe / Duct Lagging combines a loaded vinyl with a reinforced aluminum foil facing on one side.

The vinyl provides mass and flexibility while the aluminum foil adds increased mechanical strength, weather ability, an attractive appearance and improved fire retardancy.

Model LAG 'FRC’ is available with a nominal 1" thick quilted fiberglass decoupler which allows the vinyl barrier to float independently of the noise source thus maximizing performance.
