1 New roof with breathable underlay 6. WALLTITE CL00 insulation to achieve target U-value. Vapour control layer. Plasterboard and skim. Unventilated air space 5. WALLTITE returned to insulated cavity stop at head of wall 6. Breathable roof tile underlay Habitable space: plasterboard and skim/vcl with taped joints VCL to be carefully cut and sealed around struts, ceiling joists and penetrations); batten/counter batten rafters as necessary to achieve insulation depth, confirm rafter strength sufficient to receive counter battening and boarding if required. Loft space only, non habitable: insulated between and over rafters to achieve target U-value. WALLTITE may remain exposed. 5

2 Existing roof with breathable underlay. WALLTITE CL00 insulation to achieve target U-value. Plasterboard and skim (optional). Unventilated air space. WALLTITE returned to insulated cavity stop at head of wall 5. Non-combustible cavity stop, well bedded and sealed Habitable space: plasterboard and skim/vcl with taped joints (VCL to be carefully cut and sealed around struts, ceiling joists and penetrations); batten/counter batten rafters as necessary to achieve insulation depth, confirm rafter strength sufficient to receive counter battening and boarding if required.
