It specifies thermal performance requirements, including ensuring the CT/PIR is firmly secured against the inner leaf and that a suitable fire barrier is installed at the party wall abutment zone with stated minimum dimensions and thermal conductivity. It also includes air barrier continuity instructions to seal all penetrations through the air barrier with a flexible sealant, plus general notes for cavity cleanliness and references to fire and sound insulation guidance.
