At Myddleton Road the new parts of the building are wrapped in a continuous layer of woodfibre insulation which is held in place by insulating spacers. So effective are these that even the fixing screw is recessed and covered by a pellet of insulation. Flexible vapour open insulation is sprayed between the new studs and on the inside of the old brick walls. Facade cream is applied to lime pointed brickwork to reduce the effect of driving rain. A continuous airtight membrane is methodically installed, taped to seal every junction. Triple glazed units were installed throughout, even the sash windows. This all adds up to a highly energy efficient envelope, yet which allows moisture and VOCs to dissipate slowly and safely out of the building.
