WHAT TYPE OF SCREED IS REQUIRED? WHAT THICKNESS?
There is no special requirement for the screed. For domestic applications, use a fine sand / cement mix (to BS 8204) with a minimum thickness of 65mm. Radiant recommends that wherever possible the thickness of the screed is 75mm. No special screed additives are necessary. Anhydryite screeds and other types of flow screeds can be kept to a nominal thickness of 55mm and will not have an adverse effect on the pipe.
