External walls are to be 300mm wide as indicated on the drawings: 100mm blockwork; 100mm cavity with full-fill batt insulation (Knauf Dritherm 37 or similar approved); 100mm lightweight inner blockwork leaf. Walls to be render on external face and 12.5mm plasterboard on dabs & skim on internal face. Leaves are to be tied together with proprietary ties at 450mm vertical and 750mm horizontal ctrs, with vertical spacing reduced to 225mm at reveals. Proprietary insulated cavity closer/dpc to full width of cavity to be installed at reveals. Cavity below ground level is to be filled with lean-mix concrete no higher than 225mm below the underside of the lowest DPC.
