Screedboard

Screedboard (screed board) is a trademark of Cellecta Ltd [1] in the UK. It is an interlocking reinforced, high density calcium sulphate (gypsum) board. It is used in place of a free flowing or concrete screed and once laid, looks and feels like a traditional concrete screed. It can also be combined with a resilient layer (ScreedBoard 28) and be used to reduce the transmission of airborne and impact sound through separating floors.
