Marmox Thermoblocks specified on Wigan PassivHaus development

The final phase of a PassivHaus development is just getting under way in Wigan with high performance Thermoblocks from the range of Marmox being used to counter cold bridging beneath a highly insulated timber frame construction.

The St. Mary’s project is being under taken for Wigan Metropolitan Borough Council by principal contractor, Tyson Construction with Pozzoni Architecture being the lead architectural consultant and BTP Architects gilling the roll of specialist PassivHaus assessor.  All of the Thermoblocks in 100mm and 140mm widths, along with boxes of the special Marmox 360 adhesive are being supplied by Travis Perkin’s Blackpool branch.  The scheme to provide much needed affordable and easy to heat new homes has been part-funded by the Government’s Department for Levelling Up, Housing & Communities.

The Site Manager for Tyson Construction, Matt Horrocks, commented: “For fitting the timber frame soleplates it is necessary to do a ‘setting out’ course across the block-and-beam, with the dense concrete block serving to contain the screed.  The 140mm Thermoblocks are laid beneath all the external walls, followed by a 140 common brick course and then the standard blocks.  This is repeated for the internal and party walls, but with a course of 100 mm Thermoblocks creating the fully insulated barrier.”   

When complete the development will provide eight one-bed apartments, nine two bed houses and ten three bed houses, plus a further four with four bedrooms. There will also be 16 one and two bedroom bungalows.
