Alumasc Facades by K Rend’s Silkolitt Lite External Wall Insulation (EWI) system has provided a high performance, weather tight facade solution for a Supported Housing scheme in Swindon.
George Hall Court is an eight storey tower block comprising 30 flats managed by Swindon Borough Council. As part of a major redevelopment of the area, the Council was tasked with bringing the building’s energy efficiency levels up to the latest standards and improving the aesthetics to match that of surrounding properties.
The building had an existing EWI system which no longer met Part L of the Building Regulations and therefore required a thermal upgrade. The solution was to overclad the building with 2000m2 of the Alumasc Facades by K Rend Silkolitt system utilising 30mm Lite grey EPS insulation. Specialist mechanical fixings were used, with a setting tool for penetration of the existing EWI, to ensure the load was transferred through the fixing and only dissipated through the load bearing substrate. The new system resulted in the scheme’s energy efficiency being improved from a U-Value of 0.46W/m2K to 0.33W/m2K. The installation was carried out by Alumasc’s approved contractor Mark Group.
The Silkolitt decorative silicone finish has created an attractive rolled texture for the building, which now looks refreshed and modern. Silkolitt was also used to face Alumasc Facades by K Rend’s render-only system on the low level external concrete skirting and as a decorative finish in the foyer. Importantly, the nature of the EWI system enabled residents at George Hall Court to remain in their homes for the duration of the refurbishment work.
Silkolitt is a thin-coat insulated render system available for use with a choice of insulation materials including Mineral Wool, EPS and Cork. The system is BBA accredited, fully warranted and ideally suited to properties that require thermal upgrading and aesthetic improvement.
