Ecopassiv in the UK’s first cavity wall Passivhaus
Ecopassiv windows & doors were specified for our flagship Denby Dale
Passivhaus project, as a cost-effective high performance option.
Ecopassiv’s low U values and insulated frame made a big contribution to the
thermal performance of the project in Passivhaus Planning Package (PHPP).
The windows were positioned carefully within plywood boxes within the cavity
wall insulation to reduce thermal bridging to a minimum.
