How to lay floor heating reflective film
As winter approaches, floor heating systems have become the preferred heating method for many families. The floor heating reflective film is an important part of the floor heating system, and its laying method directly affects the heat dissipation effect and energy consumption of the floor heating. This article will introduce in detail the steps and precautions for laying floor heating reflective film, and attach relevant data for reference.
1. The role of floor heating reflective film
The main function of the floor heating reflective film is to reflect heat and reduce the loss of heat to the ground, thereby improving the thermal efficiency of the floor heating system. According to experimental data, floor heating systems using reflective films save about 15%-20% more energy than those without.
| Project | No reflective film used | Use reflective film |
|---|---|---|
| Thermal efficiency | 70%-80% | 85%-95% |
| Energy consumption | higher | Reduce 15%-20% |
2. Laying steps of floor heating reflective film
1.Preparation
Before laying the reflective film, make sure the ground is flat, dry, and free of debris. If there are any uneven areas, they need to be leveled with cement mortar.
2.Laying reflective film
Spread the reflective film flatly on the ground with the reflective side facing up. The reflective films need to overlap by 5-10 cm and be fixed with tape to prevent shifting.
| steps | Operational points |
|---|---|
| Ground treatment | Smooth, dry and free of debris |
| Laying reflective film | Reflective side facing up, overlap 5-10 cm |
| Fixed | Use tape to secure edges |
3.Install floor heating pipes
Install floor heating pipes on the reflective film. The distance between the pipes is adjusted according to the design requirements, usually 15-20 cm. After the pipeline is fixed, it needs to be pressure tested to ensure there are no leaks.
4.cover protective layer
Cover the floor heating pipes with a protective layer (such as cement mortar or self-leveling cement) with a thickness of generally 3-5 cm. The protective layer must completely cover the pipe to avoid direct stress.
3. Precautions for laying
1.avoid breakage
The reflective film must be protected from being scratched by sharp objects during the laying process, otherwise the reflective effect will be affected.
2.Edge fixed
The edges of the reflective film need to be firmly fixed with tape to prevent shifting during construction.
3.Pipe spacing
The spacing of floor heating pipes must be laid strictly in accordance with the design requirements. Too dense or too sparse will affect the heat dissipation effect.
| Things to note | Specific content |
|---|---|
| avoid breakage | Prevent sharp objects from scratching the reflective film |
| Edge fixed | Use tape to secure edges |
| Pipe spacing | Adjust according to design requirements (usually 15-20 cm) |
4. Frequently Asked Questions
1.Does the reflective film need to be spliced?
Yes, the reflective film usually needs to be spliced, and the splices need to overlap by 5-10 cm and be fixed with tape.
2.Can reflective film be reused?
Reuse is not recommended because the reflective film may be damaged during the construction process, affecting the reflective effect.
3.What materials are reflective films made of?
Common reflective film materials include aluminum foil, aluminum-plated film, etc. Aluminum foil reflective film has a better reflection effect.
5. Summary
The laying of floor heating reflective film is an important link in the installation of floor heating systems. The correct laying method can significantly improve the thermal efficiency and energy saving effect of floor heating. Through the introduction of this article, I believe you will have a clearer understanding of the laying of floor heating reflective film.
