Iron technology leader Saint-Gobain PAM UK, part of leading international materials company, Saint-Gobain, has published the first in a series of White Papers which tackle key issues surrounding the specification and management of above ground drainage systems for commercial and residential buildings.

Entitled ‘When put to the test a sound argument delivers cast iron evidence’, the first White Paper in the series discusses the acoustic performances of above ground drainage systems made from different materials.

Mike Rawlings, Marketing Manager – Soil & Drain at Saint-Gobain PAM UK, explained: “Specifiers have to contend with many issues when selecting above ground drainage systems. However, an increasingly important one is that of acoustic performance. Noise from gurgling pipes does little for the internal ambience for a building – especially prestige residential developments and other buildings where noise needs to be minimised, such as schools, hospitals and hotels.

“There are also cost implications for noisier pipe systems where additional insulation or fittings are needed to reduce noise to satisfactory levels in line with the new European standard, BS EN 14366:2004.

“The White Paper draws on the results of commissioned tests at independent laboratories to the BS EN 14366:2004 standard, which give a clear picture regarding the performance of varying systems. The testing process found that both mechanical cast iron and the latest push fit cast iron systems offer measurably better performance than their acoustic plastic and HDPE counterparts, and can, when covered by standard plasterboard, meet the level of dB required by Part E of the Building Regulations.

“When this is added to the other arguments in favour of cast iron – strength, durability, recyclability, sustainability, low maintenance and ease of installation, particularly of the latest Ensign EEZI-FIT push fit systems – this provides compelling evidence in favour of specifying cast iron above ground drainage systems for both new build and retrofit applications.”
