The Cumbria-based Housing Association ‘Impact’ adopted thin joint construction in its Whinfell Drive project at Kendal, which comprises of five highly energy efficient bungalows. The initial specification and design was based on timber-framed construction, which after tenders were submitted turned out to be considerably over budget. At this point, Thomas Armstrong Construction Ltd investigated the potential of using SIM construction. SIM, in this instance, consists of solid Airtec aerated block walls with a rendered external insulation. However, a SIM wall can have a variety of external finishes, including brick, timber cladding or a high pressure laminate board (HPL).
Thin Joint Technology Ltd provided comprehensive construction details for the SIM construction, enabling the designer to reduce thermal bridging, increase air tightness, increase the thermal values of the walls, floors, roof and windows, all of which easily exceed Part L requirements.
