Rushenden - Isle of Sheppey
A challenging and pioneering refurbishment project in Rushenden, Isle of Sheppey, is now complete, the results of which are hoped to be significant enough to offer the potential to develop a National Code for Retrofit.
There were dramatic improvements in the thermal efficiency and complete transformation of the aesthetic appearances of 65 properties, some of which are over 100 years old.
The properties are mostly of hard-to-treat solid brick construction and do not have the benefit of cavity insulation.
Lawtech specified Weber's BBA certified and Energy Saving Trust recognised webertherm XM EWI system for these terraced properties. The project's priority was to substantially improve the thermal insulation of the properties, from a U-value of 1.97 W/m²K to a target value of 0.30 W/m²K, which has meant that these properties have experienced an almost immediate improvement in comfort and reduced energy consumption.
The webertherm XM, specified the use of mechanically fixed 100mm thick expanded polystyrene insulation (EPS), application of weberend LAC render followed by mesh-cloth reinforcement which is encapsulated in another coat of the protective render. This is primed in preparation for the finishing coat of weberplast TF, an acrylic based decorative finish.
