Underlay for Panels on Underfloor Heating – Which One to Choose?

The underlay for panels on underfloor heating is crucial for the efficiency of the heating system and the durability of the substrate in your home, so its selection should be well thought out. Find out what to pay special attention to when purchasing and installing it.

The underlay for underfloor heating – why is it important?

Investing in underfloor heating is a long-term decision, and choosing the right underlay for underfloor heating significantly affects its efficiency. Not only does it ensure optimal heat conduction, but it also protects the floor panels from moisture and damage, guaranteeing long-lasting use and an aesthetic appearance of the substrate. Therefore, the right underlay for panels on underfloor heating is one of the most important elements to consider when installing this type of heating system.

It is equally important to consider which underlay for panels on underfloor heating is best to choose. There are various types of underlays available on the market, tailored to many types of panels and underfloor heating systems. When choosing an underlay, it is worth considering the material it is made of, its insulating properties, moisture resistance, and its ability to absorb noise. The decision should therefore be dictated by the specific needs of the room and the type of panels we plan to install.

Installing an underfloor heating system is an important step that also requires thoughtful selection of all additional elements, such as the underlay for underfloor heating. This seemingly inconspicuous component is crucial for the performance and efficiency of the system, as well as for the durability and appearance of the floor itself. When considering which underlay for panels on underfloor heating to choose, a number of factors must be taken into account that will affect the final comfort and usability of the rooms.

A deeper understanding of the layers of underfloor heating will help in making the right choice of underlay. However, before you decide to purchase, it is worth knowing the answer to two key questions. What thickness of underlay for panels on underfloor heating will be appropriate? And what thickness of panels for underfloor heating? These two aspects directly affect the efficiency of the entire heating system. At TERMOFOL, we use 6 mm thick XPS boards and 5 mm thick double-insulated underlay.

The layers of underfloor heating are similar for most floors and are as follows.

1. Concrete substrate.
2. Underlay for panels (6mm).
3. TERMOFOL heating film.
4. Vapor barrier film.
5. Vinyl panels (5mm).

Which underlay for panels on underfloor heating to choose? Also pay attention to the material. The choice of underlay is particularly important for laminated or vinyl floors, which may be more sensitive to changes in temperature and humidity.

Remember that too thick panels may improperly conduct heat, which will reduce heating efficiency. On the other hand, too thin panels may not be durable enough during prolonged use. Therefore, it is essential to select the appropriate thickness of panels that will work with the heating system.

The total thickness of the panel with the underlay should not be too large to avoid limiting the efficiency of the underfloor heating. Therefore, we recommend that the thickness of the underlay be 6 mm. This will provide adequate strength, stability, and thermal insulation. Additionally, besides choosing the right underlay, it is also important to ensure that the substrate is properly prepared – it should be level, dry, and clean.

In the TERMOFOL offer, you will find underlay for panels on underfloor heating for various types of coverings:

• for laminated panels, we recommend using double-insulated underlay,
• for other types of floors, we propose special XPS insulation boards.

Now you know what works best under panels with underfloor heating in your home!

Which underlay for panels? Underfloor Heating and Insulation

When investing in underlay for panels with underfloor heating, you should consider not only the purchase price but also the energy savings that effective insulation brings for underfloor heating. The better the floor insulation, the lower the losses your heating system will generate. Remember that no heating system will be effective if you do not provide it with the right conditions.

In addition to the appropriate underlay, it is important that the layer between the heating and the panels is resistant to moisture and mechanical damage. All of this contributes to a comprehensive approach to selecting the right materials that will ensure durability, energy efficiency, and comfort of use of the heated surface.

At this point, it is worth mentioning another important element of the infrared underfloor heating system, which is the vapor barrier film. The vapor barrier film, as the name suggests, is a building material used to prevent the penetration of water vapor through walls, roofs, and floors. Its main task is therefore to protect the building structure from moisture that can penetrate from the interior of the building to its thermal insulation. This layer is particularly important in cooler climates, where the temperature difference inside and outside the building is significant, increasing the risk of condensation.

When mentioning the underlay for underfloor heating, it should be emphasized that this is an investment that provides long-term benefits. The choice of the right underlay that is compatible with the layers of underfloor heating can significantly reduce heat loss, which is beneficial for both the environment and the household budget. Moreover, the right underlay protects the floor panels from moisture and damage, extending their lifespan.

When considering which underlay for panels on underfloor heating will work best, it is also worth paying attention to the technical specifications and recommendations of the manufacturer. Depending on the type of panels – whether it is underlay for vinyl panels or underlay for laminated panels – its parameters may vary. Therefore, it is advisable to consult with experts or manufacturers to choose a product that best meets the expectations and requirements of a given underfloor heating system.

Additionally, when considering what thickness of underlay for panels on underfloor heating and what thickness of panels for underfloor heating should be maintained, remember that these decisions can affect not only the efficiency of heating but also the overall appearance and aesthetic impression of the room. Therefore, it is worth taking the time to consider all options so that the final choice is both functional and representative.

In summary, the decision on which underlay for panels on underfloor heating to choose is an important element of any heating installation project. A properly selected underlay provides real savings on heating costs, as it prevents more heat from escaping from the building through the substrate.
