If there are walls shared with an attic, ensure that a method of supporting insulation (e.g. Framing or strapping) has been provided. The builder will need to be notified if there is none present, or the supports (strapping) will need to be provided at the time of installation by the insulator.

These walls should be insulated to the same level as the exterior walls.
