Sub-brow Eyebrow Impressive Innovation John’s house was constructed using H+H’s larger format, 100mm 3.6N/mm2 Jumbo Bloks, ideally suited to H+H’s Thin-Joint System. Aircrete was an integral element of the original specification from John who was definite on his preference for the robust solidity of a masonry construction. The bad experience encountered with the original timber frame structure also meant that the priority was to build a home whose durability and long-term value was assured. The objective was to build an energy-efficient home with year-round comfort combined with minimal running costs. The building was therefore designed following Passivhaus principles requiring exceptional thermal performance from the building fabric combined with very high airtightness performance. Aircrete, with its inherent thermal insulation, provides an ideal material for a fabric-first approach to energyefficient design while the Thin-Joint System of construction, with its minimal 2mm joints, provides optimal airtightness.
