T/L-AMG Triple Lock Medical Grade

This medical grade insulated acoustic air duct is manufactured using a dead soft perforated aluminum strip, spirally wound and mechanically joined together. The fiberglass blanket is totally isolated from the air stream by a seamless polyethylene liner, which is draped with thick fiberglass insulation and covered by a flame retardant, scrim foil mylar or polyethylene vapour barrier. Triple Lock® (T/L basic) perforated core with an open area of 20% to 25% to completely cushion sounds, such as air movement and duct vibrations. Ideal for use in medical care facilities and should allow for a comparatively noise free environment.
