SPSenvirowall has provided its TS Rail external wall insulation system for a major regeneration project at Brent’s Barham Park estate. The project involves demolishing 214 existing homes to make way for 335 new sustainable homes, ranging from one-bedroom flats to large family houses with gardens.

The development is designed to meet the Government’s Code for Sustainable Homes Level 4, and all properties must feature the appropriate technologies to help minimise heat loss and reduce noise. The insulated render system on the Barham Park estate was installed by Malden Facades, using over 3,000m2 of 160mm EPS TS Rail. Façades were then rendered with a weather friendly Granomin textured coat and NanoSil self-cleaning finish. NanoSil reduces weathering, alleviates soiling and keeps buildings looking fresh for longer.

The use of EPS is popular with specialist contractors as its quick and easy to install and unlike other insulation types, protruding edges can be rasped flat for an even finish. This prevents insulation joints ‘shadowing’ through the finish, especially on large rendered elevations. TS Rail is also exceptionally flexible, which allows for a seamless finish on even the tallest elevations of continuous render. Even the most severe deflections at intermediate floor levels can be carried through to the rendered finish, without the need for movement joints. This allows for a crisp, flawless modern look that cannot be achieved with other rain-screen clad systems.
