How to lay floor heating reflective film
As winter approaches, floor heating systems have become the preferred heating method for many families. Floor heating reflective film is an important part of the floor heating system, and its laying method directly affects the efficiency and energy saving effect of floor heating. This article will introduce in detail the laying steps, precautions and related data of floor heating reflective film to help you install the floor heating reflective film correctly.
1. The function of floor heating reflective film

The main function of floor heating reflective film is to reflect heat and reduce heat loss to the ground, thereby improving the thermal efficiency of the floor heating system. According to actual measured data, a floor heating system using reflective film saves about 15%-20% more energy than a system without reflective film.
| Project | Use reflective film | No reflective film used |
|---|---|---|
| Thermal efficiency | 85%-90% | 70%-75% |
| Energy saving effect | 15%-20% | 0% |
2. Installation steps of floor heating reflective film
1.clear the ground: Before laying, make sure the ground is flat, clean, and free of debris and sharp objects to avoid damaging the reflective film.
2.Measurements: Cut the reflective film according to the room area to ensure that the reflective film can completely cover the floor heating area.
3.Lay reflective film: Spread the reflective film flatly on the ground with the reflective side facing up. The seams need to overlap by 5-10 cm and be fixed with tape.
4.fixed edge: Use tape or special fixing clips to fix the edges of the reflective film to prevent shifting.
5.Check the laying effect: After the laying is completed, check whether the reflective film is flat and whether the joints are firm.
| steps | Operational points |
|---|---|
| clear the ground | Make sure the floor is flat and free of debris |
| Measurements | Cut reflective film according to room area |
| Lay reflective film | Reflective side facing up, seams overlap 5-10 cm |
| fixed edge | Secure with tape or clips |
| Check the laying effect | Ensure smoothness and firm joints |
3. Precautions when laying floor heating reflective film
1.Avoid damaging reflective film: Avoid using sharp tools during laying to avoid scratching the reflective film.
2.seam treatment: The seams need to overlap closely and be fixed with tape to prevent heat loss.
3.ambient temperature: The ambient temperature should not be too low during laying to avoid affecting the adhesiveness of the tape.
4.Professional installation: If you are not familiar with the laying method, it is recommended to ask professionals to install it to ensure the effect.
4. Suggestions for purchasing floor heating reflective film
1.Material selection: High-quality reflective film is usually made of aluminum foil, which has good reflective effect and is durable.
2.Thickness: The thickness of reflective film is generally between 0.05mm-0.1mm. The greater the thickness, the better the reflection effect.
3.Brand recommendation: Common floor heating reflective film brands on the market include Owentop, Weixing, etc. Consumers can choose according to their needs.
| Brand | Material | Thickness |
|---|---|---|
| Owen Top | aluminum foil | 0.08mm |
| great star | aluminum foil | 0.1mm |
5. Summary
Although the laying of floor heating reflective film seems simple, the details determine the effect. The correct laying method can not only improve the thermal efficiency of floor heating, but also extend the service life of the floor heating system. Hopefully this article will provide you with practical guidance to get the best out of your underfloor heating system.
