Marley Alutec aluminium guttering has been specified for the National Oceanography Centre Southampton, (NOCS), to provide a durable system that provides a greater rainwater capacity, without having to change the structure of the building. Due to ease of installation, the planned 16-week programme was actually completed in nine.

Aligator® Boxer 160mm, Aligator® Giant and 102mm square downpipe were supplied for the ten-storey building located within the operating port area of Southampton. The centre has a pitched roof construction that had previously experienced problems with its original plastic rainwater guttering, from storms and high levels of rainfall, since the building opened in 1995.

“The decision was therefore made to replace all of the existing guttering with an aluminium system fit for purpose and suited to its location. The consultants on the project, Gentle Consulting Limited, reviewed the products available on the market and recommended Marley Alutec as it was determined to be most appropriate product at the most realistic priceand realistically priced,” explains Lewis Rennison, Head of Facilities at NOCS.

“The exceptional quality of the product has been ideal for this project. The guttering was very easy to install and the expertise, support and training from Marley has also ensured that this project was well communicated and delivered. What we had planned as a 16-week programme was completed in just nine weeks,” says Rory Culhane, WT Roofing, who installed the product.

It was important to install a product that looked and performed appropriate to the location, which can suffer from inclement weather conditions. Aligator® Boxer, a 160mm x 100mm gutter was specified because it fitted in with the current design of the building and the required capacity. It has a rectilinear profile, ideal for modern style buildings. Boxer can be fixed with concealed fascia brackets and incorporates the Aligator® internal snap fit unions, an unobtrusive solution for quick and easy installation.

Aligator® Giant, a 200mm x 150mm commercial size trapezoidal profile with external unions and concealed supports, was chosen for some areas of the building for extra capacity. NOCS was keen to ensure that the product used had high quality aesthetics and performance and required minimum maintenance, when subjected to a marine environment. The Alutec guttering allowed for greater capacity without having to make any alterations to the structure of the building, and in addition, blended into the overall design. “The Alutec guttering system is fit for purpose and will continue to be so throughout the building’s life.” says Lewis Rennison.

Being recyclable, aluminium is an environmentally friendly solution and one that suited the environmental considerations of the project. Over 90% of aluminium used in buildings is recoverable, and it can be recycled again and again, using only 5% of the original energy required to produce it from its prime material. Currently, at least 75% of all aluminium produced during the last 120 years is still in use.
