Specification notes: heritage retrofit across façade and interior product lines is part of the9thedition’s editorial series connecting design intent, procurement, and long-term performance. We focus on decisions that repeat across commissions: materials, systems, and the way teams document intent for clients and contractors.
For product selections, we compare performance claims with installation realities, maintenance cycles, and regional availability—so teams can shortlist responsibly.
Each section includes references to measurement, not just mood: what to verify in submittals, what to test during commissioning, and what to document for future renovation cycles.
