This construction is valid for floor constructions located on ground floors where Part L insulation regulation is required.
For exact primary insulation requirements under the intermediate insulation please consult your insulation supplier. For upper floor construction see construction ID SS-U.
Services can such as flow and return pipes etc can be run within primary insulation and back filled with loose fill levelling compound..
* 100mm includes 50mm liquid screed on reduced 50mm insulation. 140mm 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.
