The most important layers of a building are often the ones you stop seeing once the job is complete.
These images show our ECO liquid screed being poured by Surrey Flow Screed Ltd. across an underfloor heating installation system before the final floor covering goes down. Once the carpet, tiles or timber is laid, the screed disappears from view, but its job is far from over.
A quality screed helps create a flat, stable base for the floor covering, while supporting effective heat transfer and moisture management for the life of the building. That matters because what's happening within the floor build-up is not always immediately visible. Screed choice is especially important when it comes to underfloor heating (UFH), as some screeds - such as our calcium sulphate-based range - can amplify the diffusion of heat across the floor, whilst cement-based screeds are naturally cold and dense, slowing down heat transference across an UFH-heated floor and amounting to substandard performance and higher energy bills for end users. Over time, an unsuitable or poorly specified screed can affect the durability, comfort and performance of the finished floor.
Anhydritec's calcium sulphate liquid screed is designed as a self-levelling, dimensionally stable screed, helping to reduce shrinkage and cracking while supporting efficient underfloor heating performance when installed correctly as part of the floor system.
For architects and specifiers, getting the screed build-up right at the detailing stage also helps avoid costly issues further down the line, with technical support available to work through project-specific drawings and queries before they become on-site problems.
