Harmer Roof Drainage – The New And Improved Range From Alumasc

Posted by judy


Alumasc has significantly expanded its Harmer Roof Drainage range, making it the most comprehensive offer on the market from a single manufacturer.

With the addition of new products and the launch of its new Drainage Calculator software, Alumasc’s Harmer brand offers benefits to all professionals involved in the design and specification of rainwater and roof drainage products.

Alumasc recently unveiled the innovative Drainage Calculator software at Ecobuild 2012, where it was heralded a major step forward for the industry. It is quick and easy to use, turning the process of foul drainage system sizing and flat roof and eaves drainage calculation, into an elementary process.

Another significant development is the introduction of a comprehensive range of cast iron rainwater outlets to create competitive choice for designers who have a preference for cast iron drainage products. The new range of outlets provides for inverted and warm roof construction whilst improving fire safety as well as accommodating wheel load capacities to meet the requirements for car park and podium deck drainage applications.

Alumasc’s Harmer brand is already the leading name in flat roof drainage, with an established product range consisting of aluminium and insulated rainwater outlets. A new Mini Balcony Outlet is now included within the aluminium range, featuring a shallow sump and interchangeable gratings in stainless steel or nickel bronze for applications requiring improvement of finish and enhanced aesthetics.

The Harmer Modulock system consists of an all new product offer comprising an adjustable linear channel system that meets the requirements of Part M Level Access compliance manufactured in galvanised or stainless steel. The new Modulock offer also extends the successful range of adjustable deck supports by simplifying levelling and adjustability during and after installation. The introduction of these products has significantly improved the choice and cost efficiency of raised deck drainage solutions available for green roofs, terraces, walkways and ballasted flat roof construction.

The Harmer range is suited to different roof types including structural concrete, metal deck, timber deck, warm roof, cold roof, green roof and inverted roof.  Harmer Roof outlets can be used with all types of membrane including asphalt, built-up felt, single ply and wet-applied systems and are suitable for applications such as  flat and low pitched roofs, car parks decks, factories and workshops, balconies and roof terraces. All products feature premium quality materials chosen for their inherent strength and durability, for ease of installation and long-life service.

Paul Hetherington, MD of Alumasc Rainwater and Drainage, comments: “No other manufacturer offers such an extensive roof drainage range at such competitive prices. The on-going development of our products and services is essential in supporting the industry – in addition to the improved range, Alumasc’s Harmer technical support is second to none and our new calculation software is proving a major benefit to contractors and specifiers.”
