If you’re looking for a floor screed to finish off your underfloor heating project, you’re going to need to decide between liquid anhydrite screed and traditional sand and cement screed. In this article, the EasyMix team is going to be covering why anhydrite screed will almost always be your preferred option.
What is anhydrite screed?
Found in natural mineral deposits and also formed as a byproduct of different industrial processes, anhydrite is a popular binder used in the creation of liquid screed. Since it was first introduced to the construction market, it has quickly overtaken traditional binders in terms of popularity.
Anhydrite screed: the benefits
No more gaps: When using liquid anhydrite screed to fully cover things like underfloor heating pipes, it’s very easy to get full coverage with no gaps thanks to its fluidity. The same can’t be said for traditional screed, which can be a real pain to make sure that all voids are covered.
Easy to lay: Given that anhydrite screed is liquid, it can be pumped straight into the site rather than being painstakingly laid by hand, making it a much simpler and less stressful job. No need to get on your hands and knees!
Speed: As well as being easier to lay, anhydrite screed is also much quicker to lay too! Thanks to the fluidity and easy pouring, liquid screed can be laid in just a couple of hours, making the perfect option for projects where time is of the essence.
Density: Liquid anhydrite screed tends to be much denser than traditional screed, which means that you get some additional soundproofing benefits. While underfloor heating doesn’t tend to be noisy, it’s nice to know that you are protected if something does go wrong.
Thermal conductivity: One of the key benefits of anhydrite screed over traditional screeds is that it has a much better thermal conductivity rating, which means it can more readily let heat pass through it. Given that anhydrite screed is often laid on top of underfloor heating systems, this is an extremely important property.
Environmentally friendly: On top of its many performance benefits, anhydrite screed is actually much more environmentally friendly than traditional screed. This is because as much as 36% of anhydrite screed is actually made up of recycled materials. It also produces a great deal less CO2 than traditional forms of screed.
Lightweight: Given that anhydrite screed can be applied as a very thin layer, this makes it much lighter in weight than traditional screed, and also means that it doesn’t require the same sort of reinforcement that can be both time consuming and costly.
