Heat Pump Adoption Pulls Thin Conductive Screed Demand
Heat pumps run efficiently only at low flow temperatures, which requires large emitter surfaces, which in practice means underfloor heating rather than radiators. That puts pipework inside a screed layer that has to conduct heat well and respond quickly, favouring thin calcium sulphate systems over thick cementitious ones. Around 37% of new residential screed now sits over heating pipework. Calcium sulphate flowing screed grows at 8.6%, the fastest here, and the connection to heating policy is direct rather than incidental. Building energy regulation publishes these timetables years ahead of the demand.
