Plastic pipe systems are ubiquitous in European building projects although they are not always easy to see. Applications in this area include hot and cold water,heating and cooling including underfloor heating, district heating, ventilation, air conditioning, sprinklers and above ground drainage such as soil, waste, overflow and rainwater.
Plastic hot and cold plumbing systems offer many benefits. The pipe can be used straight from the coil and cut to length in situ. They are lighter in weight and easier to transport than metal materials. The ability to bend pipes to fit reduces jointing and wastage. Plastic pipes do not corrode and are resistant to the build-up of limescale. No mechanical noise results in a quieter system and hot pipes are cooler to the touch. Increased demands for energy efficient buildings have led to an increase in the installation of radiant surface heating systems such as underfloor heating and an increase in building insulation within the property. These well insulated buildings therefore also need ventilation and air conditioning. Plastic pipe systems are used extensively for these applications, not only in new building but increasingly in renovation projects. Specialised plastic piping systems are also increasingly used in highly aggressive industrial applications.
PVC-U rainwater systems have been in use for decades as gutters, downpipes and fittings in domestic housing throughout the UK. Soil and waste plastic pipng systems are light, easy to handle on site and simple to install. Their advantages have made them the common choice in most markets.
