Advantages of subfloors for floor heating

A good subfloor is essential in underfloor heating and offers several advantages. First, a qualitative subfloor provides excellent thermal insulation. It prevents heat loss to the underlying structure and ensures that the heat is spread evenly through the floor, allowing you to make the most of the benefits of underfloor heating.

In addition, a subfloor for underfloor heating provides good sound insulation. It mutes contact sounds and prevents sound from spreading through the floor, creating a quiet and pleasant living environment.

In addition, a subfloor for underfloor heating provides an even and stable surface. It helps compensate for unevenness in the subfloor, resulting in a smooth and durable floor finish. In addition, it provides protection against moisture and prevents any fluctuations in the subfloor from affecting the floor.

Are you curious about which underfloor you can choose the best? Make use of our choice aid/subfloor finder, ask our specialist or Read this blog in which we help you with your choice in underfloors .

Veelgestelde vragen over Subfloor Underfloor Heating

An underlay for underfloor heating must have a low thermal resistance (<0.05 m²K/W) so that the heat is optimally transferred and efficiency is maintained.

A thin, pressure-resistant underlayment made of PU foam, XPS, or special foil is ideal. Make sure the underlayment is specifically suitable for underfloor heating.

The thermal resistance (R-value) indicates how well a material insulates against heat. The lower the value, the better the thermal conductivity.

With glue-down PVC, a separate subfloor is often not needed; a levelled surface is sufficient. For click-PVC, a pressure-resistant, thin underlay with a low R-value is recommended.
