Ashirvad Low Noise pipes comprise of a three-layer uPVC structure-based sound attenuating system made available in 40 mm to 200 mm Solfit pipes and Pushfit pipes and fittings. The noise-cancelling qualities of the uPVC outer and inner layers complemented by the mineralized uPVC middle layer minimizes the noise arising from discharge pipes. The outer and inner layers are highly resilient to impact and UV resistent and the inner layer is abrasion-resistant and extremely smooth to allow high flow rates.
