Floor build-ups, screeds and decking materials.
Compare beam and block, ground-bearing concrete slab and suspended timber ground floors for UK new builds: cost per m², insulation, where each suits.
How suspended timber ground floors work — joist sizes and spans, boards vs sheet decking, airbrick ventilation and common failures.
Compare sand-cement and liquid anhydrite floor screeds: thickness, drying times, cost per m², UFH compatibility and UK standards for each type.
P5 chipboard vs OSB3 vs plywood for floors: thickness, moisture resistance, tongue-and-groove, cost per m² and where each panel type is best used.
Compare PIR, EPS and mineral wool for floor insulation: lambda values, thickness for target U-values, UFH build-ups, cost per m² and Building Regs requirements.
