RAINWATER SYSTEMS Zink Copper Stainless Scottish winters dictate upgrade to Legacy Cast Aluminium Guttering on refurbishment RCIMAG.COM MARCH 2018 089 Understanding rainwater drainage with Harmer The latest RIBA-approved CPD from Harmer Drainage is said to offer in-depth insight into modern rainwater drainage systems and their importance in protecting buildings from water damage. The one hour seminar, entitled ‘Internal Rainwater Drainage – Design and Specifi cation’, is aimed at educating architects and engineers about the importance of a welldesigned drainage system. The CPD reportedly addresses national and regional rainfall characteristics and how this affects design and product choice, as well as how to meet the British Standard requirements for gravity drainage systems. Seminar attendees will be able to relate different roof constructions with the detailing of rainwater outlets, identify pipe materials and methods of connection, and understand the importance of robust specifi cation in rainwater systems. Maintenance, inspections and incorporating blue and green roof systems are also covered. The Harmer seminar forms part of RIBA’s CPD core curriculum. Architects are required to complete 20 hours CPD on these core subjects per year, plus an additional 15 hours on topics of their choice. Wayne Willmott, Harmer’s national sales manager, who wrote the CPD, said: “It’s vital for architects and engineers to dedicate time and consideration to rainwater drainage systems in order to avoid roofi ng failures. This CPD covers the main points to think about and ensure the right elements are in place to protect buildings from rainfall.” www.harmerdrainage.co.uk Eskgrove homes was employed to extensively refurbish a property in the Glenshee area of Perthshire. The property, once completed, will comprise of ten bedrooms, kitchen, reception, playroom, dining room, hall and living room. Some parts of the property reportedly date back to 1583. The existing cast iron guttering system needed replacing, but due to the increased capacity required to disperse melted snow from the property rather than just rainwater, simply replacing the system wasn’t an option. A higher capacity rainwater system was required. Eskgrove Homes liaised with its local builders’ merchant Jewsons to see what the best options on the market was. As both are existing customers of ARP they soon contacted their local area sales manager for Scotland – Archie Pringle for support. Archie said he worked closely with Eskgrove and Jewsons to understand the needs of the client, and ensure that the right product was specifi ed. Archie was also able to provide free samples of the material and the special colour of RAL 7001 Matt Silver that the client required, before the order for the material was placed. Archie specifi ed Legacy Cast Aluminium Deep Flow Guttering, as it is made from cast aluminium, and is specifi cally designed to replicate cast iron. However, in this instance, allowance was made for a higher fl ow capacity for the rain and melted snow. The gutters were teamed with Colonnade Cast Collared Rainwater Downpipes, which is said to mimic the look of cast iron to provide the heritage style required to suit the property. ARP’s Legacy Cast Aluminium Gutters and Colonnade downpipes are said to be an ideal replacement for cast iron due to being lightweight, easy to install and can be coated in over 200 standard Polyester Powder Coated RAL/BS colours. Aluminium is a naturally occurring and a highly recyclable material. It is reportedly non-toxic and non-corrosive, and requires very little maintenance over its long lifespan. Colin Cumberland, director of Eskgrove Homes, said: “The advice and service provided by ARP gave us confi dence that our choice of rainwater system would be able to handle the challenging weather conditions, and also suit the heritage style of the property.” www.arp-ltd.com 01992 801927 www.almhm.co.uk The property in the Glenshee area of Perthshire CRM RAINWATER_q 03/06/2013 12:46 Page 1 The new CPD from Harmer Drainage: ‘Internal Rainwater Drainage – Design and Specifi cation’
