How to lay floor heating reflective film
Floor heating reflective film is an indispensable part of the floor heating system. It can effectively reflect heat and improve the heating efficiency of floor heating. The correct laying method can not only improve the use effect of floor heating, but also extend its service life. This article will introduce in detail the laying steps, precautions and related data of floor heating reflective film to help you better complete the laying work.
1. The role of floor heating reflective film
The main function of the floor heating reflective film is to reflect heat and prevent heat from dissipating downward, thereby improving the thermal efficiency of floor heating. In addition, it can also play the role of moisture-proof and sound insulation, and is an important auxiliary material in the floor heating system.
2. Laying steps of floor heating reflective film
1.Preparation: Clean the floor to ensure it is flat, dry and free of debris.
2.Laying reflective film: Lay the reflective film flat on the ground, with the aluminum foil side facing up, and glue the seams with tape.
3.Fixed reflective film: Use special tape or nails to fix the reflective film to prevent it from shifting.
4.Laying floor heating pipes: Lay the floor heating pipes on the reflective film according to the design drawings and fix them with staples.
5.Inspection and acceptance: After the laying is completed, check whether the reflective film is flat and undamaged, and whether the joints are firm.
3. Precautions for laying floor heating reflective film
1. The aluminum foil side of the reflective film must face upward, otherwise the reflection effect will be affected.
2. The seams need to overlap by 5-10 cm and be bonded with tape to prevent heat leakage.
3. When laying, avoid scratching the reflective film with sharp objects to avoid affecting its performance.
4. After the reflective film is laid, the protective layer should be covered as soon as possible to avoid prolonged exposure.

5. Frequently Asked Questions
Q: Can the floor heating reflective film be reused?
A: It is not recommended to reuse it because the reflective film may be damaged during the laying process, affecting its reflective effect.
Q: Do expansion joints need to be left when laying the reflective film?
A: There is no need to leave expansion joints, but the joints need to overlap and be bonded with tape to ensure tightness.
Q: Does the reflective film need to be covered with a protective layer after it is laid?
A: Yes, the reflective film should be covered with a protective layer (such as cement mortar or floor) as soon as possible after laying to avoid damage.
6. Summary
Although the laying of floor heating reflective film seems simple, the details determine success or failure. The correct laying method can not only improve the thermal efficiency of floor heating, but also extend the service life of the system. I hope this article can provide you with practical guidance to help you successfully complete the laying of floor heating reflective film.
