Fibre cement EQUITONE [tectiva] has been used to create a sustainable facade for a low energy, timber frame modular building installed at the Building Research Establishment (BRE) Innovation Park at Ravenscraig in North Lanarkshire.
Marley Eternit is working with Hoos to demonstrate how innovative approaches to sustainable design and construction can improve the built environment.
Architects at Hoos, based in Glasgow, chose an EQUITONE architectural fibre cement facade material because it can achieve an A+ rating as defined in the BREs Green Guide to Specification based on generic rating for autoclaved fibre cement single sheet - (Element Ref: 80623042, 806230422, 806230447, 806230450).
EQUITONE [tectiva] was chosen in Pebble, with its characteristic fine sanded lines, natural occurring hues and through colour, creating a natural yet unique aesthetic effect for the modular building.
Stephen Good, Director at Hoos, said: "We chose EQUITONE [tectiva] because it offered the perfect balance of appealing natural aesthetics and sustainability. Marley Eternit delivered the panels to our workshop where they were cut to the required size and fitted to the pod in our factory. The completed building was then delivered for rapid installation at the BRE Innovation Park."
The entire pod was manufactured off-site as a completed modular building in the space of four weeks. This allowed the pod to be installed on site in a matter of hours. It is being marketed by Hoos for use as a home office, garden room and even holiday home.
A recycled natural fibre insulation material was installed in between the timber framework sections with the fibre cement panels secret fixed directly to timber battens using structural adhesive to create a sheer facade. As the building is a non-permanent, temporary structure, it didn't need to meet regulatory guidance in terms of U values, but the walls would achieve circa 0.24W/m2K.
Katy Hunter, Consultant at BRE Scotland, said: "The Hoos pod demonstrates the benefits of off-site manufactured, potentially off-grid buildings. It is a demonstration building that is visited during tours of the Innovation Park, and can also be used for additional meeting space, if the Visitor Centre is busy."
Although the Hoos Pod is a temporary structure, Marley Eternit facade solutions have an installed life expectancy of at least 50 years, making them ideal for all sustainable and affordable buildings. The fibre cement material requires no routine maintenance and is resistant to rot and fungi, making it a highly cost effective material over the whole life of the building. It has a fire classification of A2-s1, d0 to EN 13501-1.
The Hoos pod at the BRE Innovation Park is 2.4m by 3.6m, allowing it to comply with permitted development size rules and planning permission would not be required, in most cases, for a homeowner to have a Hoos pod installed in their garden. Hoos offer a variety of different modular sizes, from 6m2 to 60m2, which can be installed as individual or combined into multiple pods.
