Minimum Screed For Underfloor Heating

Underfloor minimum screed for underfloor heating (UFH) is a cost-effective and energy efficient way to heat a room. It spreads the warmth evenly and requires less energy to achieve the desired temperature than traditional wall and ceiling heating.

The success of UFH relies on the right floor construction and screed. To ensure the system functions as it should, an insulation layer and a suitable screed need to be laid before the UFH is fitted.

Minimum Screed Thickness for Effective Underfloor Heating

Choosing the right type of screed for underfloor heating is vital, and there are two main types available; bonded and unbonded liquid screed. Both can be used with underfloor heating, but there are a few important differences.

Liquid screed is usually the preferred choice for underfloor heating, as it can be walked on almost immediately after application. It’s also much faster to dry than a traditional cement-based screed, and can be applied to a lower construction height.

When installing a liquid screed for underfloor heating, it’s essential that the pipe is firmly clipped in place and stress relief joints are fitted around walls, pillars and other uprights. It’s also important to ensure the liquid screed is mixed to the correct consistency, as a too-thick mix could result in unevenness in the finished floor. A minimum of 21 days is recommended for curing times for a typical liquid screed, but it’s possible to speed up the process using a pre-mixed accelerated screed.
