PermaRock Mineral Fibre External Wall Insulation (EWI) with SiliconeUltra and Brick Slip finishes retrofitted to exemplar energy efficiency scheme in Nottingham (for Nottingham City Homes).
Known collectively as "The Courts," the 5-storey properties are of concrete cross wall construction with brick outer skin on the gable walls.
The £4 million project entailed building new plant rooms, installing solar PV panels, and installation of an external wall insulation to four residential blocks.
The project also features Britain's largest battery storage facility for domestic energy, and the country's first low temperature district heating system.
The specified EWI system was the PermaRock Mineral Fibre EWI system incorporating non-combustible (EuroClass A1) stone wool insulation and a high-performance nano-quartz self-cleansing decorative render, PermaRock SiliconeUltra K-Finish.
The system is suitable for installation above DPC level on all building types and heights and is tested and assessed to EN 13501-1:2007 + A1:2009 (A2-s1-d0 fire classification) confirming compliance to the latest revisions to the Building Regulations.
