Environmental Impacts
Gyvlon Flowing Screeds can greatly reduce carbon content and increase recycled content Vs sand cement
Gyvlon screed binder is produced using Synthetic Anhydrite which is a by product of industry. By using this by product Gyvlon screed production does not require the high levels of quarrying of energy consumption associated with cement.

Gyvlon Screed and Carbon Reduction
Carbon footprinting has become a more considered part of building design within the built environment. It is important to understand how Gyvlon screeds can aid in the reduction of carbon emissions compared to cement based products, Gyvlon achieves these reductions due to two significant production facts.
Firstly, as you will have read in our environmental section, Gyvlon binder is made from an industry by-product 'Synthetic Anhydrite'. Synthetic Anhydrite has a much lower embodied energy than the quarried/mined materials associated with cement production. Secondly, synthetic anhydrite does not require heat to be applied during its processing, when compared with the 'kiln burning' process of cement which can be as high as 1450°C this allows massive carbon savings to be generated.
Whilst the two factors above make a major saving of 262Kg Co2/m3, Gyvlon screeds generate further savings by being installed thinner. The thinner Gyvlon screed section reduces the amount of screed material required, especially when you consider that the market leading Thermio+ product can be installed at just 20mm cover to underfloor heating pipes. The image below shows typical savings based on various project sizes.
If you require something more specific please contact our specification team who will be happy to calculate the carbon reduction for your project.
Environmental Benefits of Gyvlon Screed in Manufacturing
The Environmental benefits of Gyvlon can be broken down to material sourcing, manufacturing energy consumption, material delivery and material usage on site. Below you will find the production process and summary of each saving.
Gyvlon Screed - Material Souring
Gyvlon binder is manufactured from a synthetic anhydrite which is a by product of the chemical industry. Prior to the material being used for floor screed binder it could've gone to landfill or have been disposed of in the Fjords of Norway. As you will see from the table Gyvlon utilise approx 980kg of synthetic anhydrite per tonne of binder, compared to the 1.6 tonne of raw material required to produce a tonne of cement. Meaning each 1000m2 of Gyvlon installed reduces landfill by 34 tonne. In addition to an increased recycled content in construction Gyvlon screeds are also 100% recyclable at the end of the buildings life cycle.
Gyvlon Screed - Energy Consumption
Since Gyvlon's manufacturing process doesn't require the kiln burning phase associated with cement production there is a considerable energy saving per tonne. Cement is kiln burnt at around 1450 degrees during it manufacture were as Gyvlon is not subjected to heat other than that created during the milling process.
Gyvlon Screed - Material Delivery
Gyvlon binder is delivered from our production facility to readymix plants, transmix delivery units and bagging facilities where it is silo stored ready to be converted to screed mortar or pre blended bagged material as required. The eliminates the generation of unnecessary amounts of waste packing and the associated environmental impact.
Gyvlon Screed - Material Useage
All of Gyvlon's screed and system solutions benefit from higher flexural and compressive strengths than you'd expect from sand cement, meaning the total screed depth can be greatly reduced offering up to a 40% saving in the raw material required and delivery truck movements.
