Herefordshire Screeding Latex Screeding Thermio

Liquid screed offers benefits across the board when compared with concrete based methods and is especially recommended for builds with under floor heating. Savings can be made in the time and manpower needed to lay liquid screed, 100m2 can be laid in less than 45 minutes and the surface will be dry enough to walk on in between 24 to 48 hours.

Concrete – Density – Heat Capacity – Thermal Conductivity

Thermal conductivity (sometimes referred to as k-value or lada value (λ)) is a measure of the rate at which temperature differences transmit through a material. The lower the thermal conductivity of a material, the slower the rate at which temperature differences transmit through it, and so the more effective it is as an insulator.
