The high thermal comfort provided by underfloor heating is one of the most frequently mentioned advantages. However, for underfloor heating to fulfill its function, it must be well prepared. One of the most important elements is the foil placed under the installation. What are its tasks and why is it used?
Why is foil placed under underfloor heating?
A well-fitting foil allows you to increase the efficiency of underfloor heating. Its most important task is to protect against heat loss and protection against possible moisture that could damage the installation. Another advantage is the ability to eliminate small differences that occur in the substrate. The underfloor foil is covered with a layer of aluminum, which allows it to reflect heat and heat the house more effectively.
Another added value is that by selecting the appropriate variant of underfloor heating foil, the acoustic parameters of the room can be improved.
Which foil for flooring? What to pay attention to when choosing the right product
The factors that you should definitely pay attention to first are strength, durability and the degree of insulation. It is best if it is a special foil created with the specific needs of underfloor heating in mind, so it is worth having it equipped with an aluminum layer, as this will reduce heat loss. Even though this type of foil is slightly more expensive than traditional construction foils, the higher expense will be returned by reducing heating costs. An alternative may be the slightly less common screen or raster foils, as well as polyethylene foils, although the latter are used rather to insulate floors located directly on the ground.

Similarly, differences can be noted in the case of the product thickness, because in the first variant it is as much as 0.13 mm, which is one of the highest parameters available. are currently on the market, while the second variant is slightly thinner, i.e. 0.105 mm. These values are quite similar, but in the case of underfloor heating installations there is a big difference. Which variant should you choose? The best solution is to choose based on the individual needs of a given project. Only properly tailored solutions allow you to optimally use the properties of the increasingly popular flooring. It is a good practice to use the help of professionals. When commissioning the installation of a heating system to specialists, it is best to ask a selected team for help in matching individual elements to be sure that everything will be adjusted properly and the finished installation will meet the highest standards, ensuring maximum thermal comfort.
PURMO underfloor heating foil is also very popular. Foil with printed lines that allow for easy pipe laying. The advantage is that the foil is equipped with a special mesh that prevents the clip securing the pipe from being torn off.
