Anhydrite Liquid Screeds
What are anhydrite liquid screeds?
Anhydrite liquid screeds are designed to provide a smooth level surface in both commercial and domestic buildings prior to application of floor finishes. It can be used bonded, un-bonded or floating and with or without underfloor heating.
The main benefits to a Thermio anhydrite screed
- Designed to improve the thermal performance of the underfloor heating systems allowing your system to run at lower input temperatures - therefore saving you money.
- It is the ONLY screed to guarantee a minimum thermal performance approved by the BBA, allowing UFH designers to maximise the performance of your system.

The main benefits to a Eco anhydrite screed
- Designed to provide a smooth level surface in both commercial and domestic buildings prior to the application of floor finishes.
- Can be used Bonded, un-bonded or Floating with or without UFH and is BBA approved.
- This screed can be laid thinner, with bigger bay sizes, no reinforcement, no curing membrane offering greatly reduced cracking and faster installation compared to traditional sand cement screeds.
