Insulation for underfloor heating
Clockwork Screed supplies insulation for underfloor heating. Insulation is a critical element of underflooring heating installations.
What insulation is used for underfloor heating?
If you’re considering what insulation to use for underfloor heating, there is a range of insulation options for underfloor heating to choose from. However, the choice is usually between insulation boards and poured insulation.

poured insulation for contractors and property developers across the North West.

Why insulation is critical for underfloor heating performance
Insulation is critical for underfloor heating performance because it acts as a thermal barrier to prevent the downward escape of heat from the system pipework into the ground or subfloor. The heat from an underfloor heating system must be directed upwards into the room above to maximise its performance.
Underfloor insulation will also speed up the response times of the underfloor heating system to heat the room more quickly, and provide an even distribution of heat throughout the room. Insulation also allows underfloor heating systems to run at lower temperatures which maximises energy efficiency for cheaper running costs and reduced environmental impact.
Types of insulation used with underfloor heating systems
Insulation boards are often seen as the more traditional option for underfloor heating insulation, but they can be problematic when subfloors aren’t level. There is also a considerable amount of labour involved in cutting the boards to size and installing them to accommodate existing pipework, and there needs to be plenty of room to store the boards prior to installation.
The introduction of poured insulation, as supplied by Clockwork Screed, transformed the construction sector’s approach to underfloor heating installations. Here are some of the benefits of poured insulation compared to insulation boards:
- Poured insulation is quicker to install. The Clockwork Screed team can cover 1000m² a day
- Once the insulation is poured onto the subfloor it self-levels, overcoming the levelling issues that often occur with insulation boards
- Poured insulation produces a smooth layer without voids onto which an underfloor heating system can be easily installed
- Clockwork Screed’s poured insulation offers excellent thermal properties, is exceptionally strong and easy to work with
Poured insulation produces zero waste because it is batched to order.

How insulation is installed beneath underfloor heating
This is how Clockwork Screed installs insulation beneath underfloor heating:
- The subfloor is prepared, ensuring it is dry with no debris or grease
- An edging strip is installed around the perimeter of the space to allow the insulation to expand and contract depending on the temperature
- The insulation is poured onto the prepared subfloor
- Once installation is complete, the insulation is left to self-level, dry and cure
- The result is a smooth, level thermal barrier that will maximise the performance of the underfloor heating system
