For above-ground cast iron drainage systems in installations where high acoustic performance is required, Saint-Gobain Pipelines has introduced a dampener fitted to its standard bracket. This is said to eliminate the lagging laid down in the guidelines for pipes passing through walls and floors.
Part of the Ensign range, the bracket is said to offer an exceptional sound deadening performance which has been tested to new European standards.
While UK building regulations for sound insulation and noise reduction do not specifically cover requirements for wastewater systems, acoustic performance in schools and hospitals is now important.
