The Green Screed

An overview of the embodied-carbon advantage of anhydrite flowing screeds compared with traditional cementitious systems.

About this document

Drawing on independently verified Environmental Product Declarations, this document sets out why anhydrite-based Gyvlon screeds carry up to 90% less embodied carbon than equivalent cementitious build-ups.

It explains the chemistry behind that advantage, the role of recycled content, and how to position screed selection within a wider RIBA 2030 or LETI carbon strategy.
