Our new Thermal Bead Screed (TBS) is a lightweight thermal insulation sub base flooring material laid by skilled installers. It is an ideal insulating sub-base screed for domestic & commercial buildings and especially under floor heating.
TBS is produced using Energystores thermal lightweight aggregate produced in a ISO 9001, ISO 14001 and IOSH 18001 quality controlled environment. This aggregate is made by combining EPS beads with a unique chemical additive and has been used to install 10 million square metres of floors in over 40 countries worldwide.
TBS also benefits from fast even laying and quick drying (walked on in 24 hours)
