This self-build project in Wakefield consisted of a 102m2 ground floor foot print which was designed to meet very high environmental standards to and needed to be as thermally efficient as possible.
The client elected to use 170mm deep thermal insulation to underlay a standard warm water underfloor heating using a sustainable geothermal heat source. Gypsol Classic Screed was selected as a cost effective and practical alternative to traditional sand cement screed initially specified. Gypsol Classic was selected as it can be laid relatively thin allowing coupled with the high thermal conductivity of the material, makes it significantly more thermally responsive, requiring lower flow temperatures making it perfect for use with this type of underfloor heating system. In this project the screed was laid at just 55mm deep.
The choice to use Gypsol Classic screed was also influenced by the sustainability criteria associated with its manufacture. Gypsol binder contains 98% recycled material and when incorporated into a floor screed offers savings on carbon emissions of up to 95% compared to sand cement screed.
Additionally, as Gypsol Classic screed is free flowing, self- compacting and installation is ergonomically advantageous the impact on health and safety of the installing contractors was significantly lower than would have been the case had traditional screed been used.
The Gypsol Classic screed was poured once the building was weather tight and once dried was subsequently overlaid with a variety of floor coverings including carpet, tiles and engineered wood.
