UNDERFLOOR HEATING WITH THERMALLY

An underfloor system with a high thermally conductive self-compacting anhydrite screed provides improvements over conventional screed or slab construction systems. Increased thermal conductivity reduces reaction time and the flowing nature of a self-compacting screed results in an improved pipe coating, enhancing the pipe/screed interface, which

Floor screeds

A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.
