The ASFP Purple Book: Designing Fire-Resisting Partition Walls Right.
This major update of the ASFP Purple Book strengthens its focus on the design of fire-resisting partition walls, recognising that their performance is determined long before installation begins. It provides clearer guidance on the selection, coordination, and integration of partition systems with services, doors, structure, and supporting fire-stopping - all aligned with tested evidence.
The revised document supports a structured, auditable route from design intent through installation to long-term fire performance, reducing reliance on site-based correction and unsupported assumptions.
