Underfloor Heating Screed




A wet underfloor heating system covered with screed allows for efficient heat transfer from pipes to the flooring. Screed helps fill up all the gaps and leaves no room for air bubbles to develop, preventing the disruption of thermal energy exchange when pipes are warmed through the water. In this way, there is an even distribution of heat across the whole floor space, providing a warm environment.

K M Flow Screed provides the installation and repair services for underfloor heating screed. Providing professional advice regarding the underfloor heating system and screed installations, we ensure to undertake best practices for completing the whole project.

Advantages of Laying Screed over Underfloor Heating

Laying screed flooring over underfloor heating provides you with several benefits:

  • Enhances the energy efficiency of underfloor heating.
  • Creates a flat and smooth surface that is easy to clean.
  • Allows for improved and even heat distribution to the entire floor.
  • Requires less time to get dry, minimising disruptions.
  • Provides a durable and hard-wearing surface with low maintenance requirements.

We Install Liquid Screed with Underfloor Heating System

We provide specialist services for installing liquid screed with an underfloor heating system, allowing efficient thermal movement and expansion of pipes. With easy pouring and faster installation, it allows project completion in less time.

It gets dried quickly and becomes hardened, providing a flat and smooth surface and allowing you to walk over it within 24 to 48 hours of its installation.

We Carefully Determine the Screed Depth

Fully understanding the importance of keeping pipes at optimum depth, we carefully determine the thickness of the screed layer. Usually, our experts install screed at a minimum depth of 50mm or 55mm to create a thinner layer over the underfloor heating system’s pipe work.

In this way, we ensure the system works with greater efficiency, allowing for even heat distribution and consistent temperature throughout the room.

What should be the minimum depth of underfloor heating screed?

The minimum depth for the wet underfloor heating screed is 65mm for hand mixed and 50mm for liquid screed

Do I need insulation beneath the underfloor heating screed?

Yes, a layer of insulation beneath the underfloor screed will increase energy efficiency and reduce running costs by preventing heat losses downwards.

What are the benefits of underfloor heating screed?

There are several benefits of underfloor heating screed, such as:

  • Increased energy efficiency.
  • Smooth and flat finished surface.
  • Improved heat distribution.
  • Less drying time.
  • Low maintenance requirements.

Does the underfloor heating screed enhance the efficiency of the system?

Yes, underfloor heating screed can increase the efficiency of your underfloor heating system by up to 30%.
