Which Screed?

Traditional sand : cement screed. This has been the standard for finished floors for many years. Over the years various additives have been introduced to reduce cracking and curling, increase wearability, decrease drying times, as well as meeting the different needs of customers. With changes to building control legislation in relation to the required max ‘U’ Value for floors, insulation is getting thicker and screeds are getting thinner. This is to avoid losing ceiling height or increasing the build height (which is not always possible in certain conservation areas). This, added to the introduction of under floor heating systems, has led to the introduction of thinner screeds such as Cemfloor Liquid Screed. Cemfloor screeds are very responsive to underfloor heating; due to the fact that

they can be laid in very thin sections and have a high thermal conductivity of up to 2.9w/mk. Since Cemfloor is a cement based screed; floor coverings can be applied much faster than calcium sulphate screeds which require a final moisture content of 0.5% which can delay floor finishings by months. Whereas Cemfloor can be tiled at a final moisture content of 5% and timber floors can be installed at a final moisture content of 2.8%; speeding up the entire build process. Compared with other liquid screeds which generally need to be force dried with underfloor heating; Cemfloor screeds can be used in non heated floors as it doesn’t require force drying to remove moisture.
