When Carillion and partner HLM Architects were looking for materials for 13 new build primary schools in Barnsley they knew they had to be robust, low maintenance and sustainable. At King's Oak, Kalzip's Falzinc raised seam roofing met all the criteria. Falzinc uses a patented Pegal process to encase the aluminium core of the raised seam with a pre-weathered zinc layer that has a lower weather erosion rate than zinc and is long living due to the saline resistant substrate. The weathering treatment gives the zinc surface a mid grey shading - the appearance of approximately three-year old natural zinc. At King's Oak the sheets were fixed with associated flashings and fascias as well as gutters to prevent run off from cedar boarding above roof levels affecting the zinc. Because cedar board rain run-off attacks the surface of zinc care was needed throughout construction and secret gutters were built to prevent future damage.

The launch of the Equator, the push-fit hot and cold water system from Marley Plumbing and Drainage has proved to be more than a flash in the pan, according to the manufacturers, and the range has proved to be a success with specifiers, developers and installers. The equator pipe and fittings are manufactured from high grade engineering plastic, cross linked polyethylene and used for hot and cold central heating systems across domestic and commercial buildings. A grip release mechanism enables fittings to be taken apart using a demounting tool, ensuring a reusable and adaptable fitting. Available in sizes from 10mm to 28mm, the Equator range also includes a variety of manifolds in two, three and four port options, with and without control values. The principle of the manifold is simple: to provide a central point for all plumbed in facilities and radiators, either by floor or in one location. This ensures that individual pipe runs can be isolated for extension or maintenance.

The Access valve from Aquaflow is now available on the market. The valves are designed to control water distribution in buildings with recorded water savings, in many cases by as much as 25%. The same size as a conventional service valve, Access includes a ball shut off, an water regulator and a side service port for access while the valve is in use. Inside the eye of the ball valve the Aquaflow water regulator limits maximum flow at the outlet to a predetermined level, regardless of fluctuations in supply pressure between 1 bar and 10 bar. By providing each outlet with its correct water supply, the problems of maintaining services at the end of a long pipe run on higher floors may be solved, often without the added cost of break tanks of pumped circulation systems. By controlling maximum flow rates, water savings of a quarter have been recorded, cutting fuel, water and waste charges

Water regulators from Aquaflow could keep water consumption under control, even if the pressure fluctuates wildly between one and ten bar. The regulators limit each outlet to a chosen, preset maximum flow rate. These are produced in stepped flow rates from 4 litres per minute for washroom taps, to 18 litres per minute for a bath. Because the products control flow with a minimal pressure drop, the company claims that users will be unaware of any change in service.

The recently released BA 295 compact backflow preventers from Honeywell are designed to ensure contaminated water cannot flow back into the public mains supply. The valves are designed to meet the requirements of the UK Water Regulations Advisory Scheme (WRAS) and use the well-proven RPZ -reduced pressure zone principle. They are suitable for industrial and commercial premises, and for residential buildings within the scope of their specification. They protect drinking water systems against back pressure, back flow and back siphonage ensuring compliance with relevant water regulations.
