The ambitious project, and one of the first certified PassivHaus homes in the UK - The Denby Dale house in West Yorkshire has been successfully shortlisted at the UK PassivHaus Awards.
The specification of the Denby Dale house required outstanding performance insulation - which is fundamental to a project like this. Knauf Insulation met the requirements by providing the BBA Certified Earthwool Dritherm 32 Ultimate Cavity Slabs for the walls, Earthwool CarbonZero Loft Roll 44 for the roof void (both of which incorporate ECOSE® Technology – which extends the green credentials as it is manufactured with 70% less energy than traditional binders and the products contain no dye or added formaldehyde) and the high performing Polyfoam Floorboard Standard.
Glass mineral wool was specified over rigid insulation to ensure a tight thermal fit. Earthwool DriTherm Cavity Slabs are flexible enough to eliminate air gaps and prevent heat loss due to their inherent ability to knit together at joints between the slabs. In addition to its thermal performance glass mineral wool also has other sustainable features. In manufacture it uses a high content of recycled glass bottles and requires less overall energy consumption than some alternative products, resulting in less carbon emissions.
