EXTERNAL WALL INSULATION USED TO CREATE GEORGIAN, 30’S STYLE, OR ULTRA-MODERN ARCHITECT DESIGNED HOMES

Architects have used external wall insulation to create homes in very different styles, reminiscent of different eras, but all winners of the coveted INCA Andy Swan Award. This is sponsored by the Insulated Render and Cladding Association for the best use of insulated render.

          Whitewood is a new private house, of 800 square metres in area, at Virginia Water, Surrey, which has won the category for an individual house. The architect, David Butler and Associates, required a “modernist version of a 30’s style house”. This was in deliberate contrast to the surrounding neo-Georgian and mock-Elizabethan mansions.

          They chose a Sto external wall insulation system, with 100mm and 200mm EPS insulation, to achieve excellent thermal efficiency with a 0.23Wm²K U-value. This was finished with crisp, maintenance-free white render, giving an appearance of ‘sharp edges’ to the building. The substrate was medium density concrete block. The system designer was Sto Ltd, and the installer, Walltec Ltd – both INCA members.

          On a larger scale, two developments were winners in the new private apartments, low-rise category. Beautifully detailed with traditional Georgian appearance, this category was won by a development at Broughton Green, High Broughton, Salford, Manchester.

This comprises large family houses and apartments designed to reflect modern living. With energy costs escalating at a rapid rate, extra care and attention has been paid to the design of the properties to ensure they achieve significantly better thermal efficiency than levels required under current Building Regulations.

The PermaRock insulated render system contributed to the low U-value and enabled the traditional look required by Church Lukas Architecture, to be achieved with the use of profiles and raised features. The system incorporated 150mm and 30mm mineral fibre insulation onto a Kingspan TEK panel substrate, and was finished with white silicone render. The system designer was PermaRock Products Ltd, and the installer E J Horrocks Ltd – both INCA members.

          Broughton Green is the creation of a new community through regeneration of a 30-acre site, with the aim of building a sustainable environment, drawing new families into the area to create an integrated community alongside existing residents.

          Runner-up are ultra-modern apartments at Dunepoint, Clifton Drive North, Lytham-St-Annes. This development comprises luxury apartments, including two penthouses, built directly onto the dunes of Lytham sands. It was monitored closely by Fylde Borough Council to ensure all aspects of the work were carried out in accordance with the detailed planning permission. The project won the Daily Mail Northern Apartment of the Year Award.

The specifier, Fallows Gowan Partnership wanted clean, modern lines, using the Weber-therm XP external wall insulation system, to achieve the required 0.32W/m²K U-value, and finished in one-coat through-coloured scraped textured render in beige for quick installation and low maintenance. The substrate was block/panel and masonry. The system designer was Saint-Gobain Weber Ltd; and the installer, Render Systems Ltd – both INCA members.
