TGD L 2008 – B.7.5 – FLOOR COnSTRUCTIOnS, Construction F5: Exposed floor: solid concrete, insulation external

B.7.5 Construction F5: Exposed floor: solid concrete, insulation external Installation guidance and precautions If the walls are internally insulated, this floor construction is not recommended. Floor insulation should instead be located internally in order to connect with the wall insulation. With cavity wall insulation, thermal bridging may be minimised by supporting the external leaf independently, and continuing the external floor insulation around the edge beam to connect with the cavity insulation as shown in Diagram B22.
