This construction is suitable intermediate floor constructions. No further insulation is required to meet Part L requirements.
For ground floor construction see construction SS-G
Services can such as flow and return pipes etc can be run within primary insulation and back filled with loose fill levelling compound..
* 80mm includes 50mm liquid screed on 30mm insulation. 95mm includes min. 65mm sand cement screed on typical 75mm insulation. For additional load i.e. 3 kN/m² increase by further 15mm anhydrite or 20mm sand /cement.
Strict heating up protocol applies with all ‘in’ screed systems.
