There are generally two materials for floor heating reflective films, one is aluminum foil reflective film and the other is PET reflective film.
The advantage of aluminum foil reflective film is that it has good thermal conductivity and can transfer heat quickly. At the same time, aluminum foil material has good thermal insulation properties and can reflect heat into the room and. reduce energy losses. In addition, aluminum foil reflective film also has the advantages of being moisture-proof, mildew-proof and corrosion-resistant, which can effectively extend the service life of the floor heating system.
The advantages of PET reflective film are that it is thin, soft, easy to install and relatively inexpensive. The reflectivity of PET reflective film is also very high, which can effectively reflect the heat of the cunderfloor heating and improve the energy efficiency of underfloor heating.
Overall, the thermal conductivity and insulation performance of aluminum foil reflective film are better than that of PET reflective film. Therefore, when choosing reflective film for underfloor heating, it is recommended to choose aluminum foil reflective film. However, the price of aluminum foil reflective film is relatively high. If the budget is limited, you can also choose PET reflective film, but you should pay attention to choosing products with reliable quality.
This type of aluminum film is generally a plastic layer on the surface of the aluminum foil. The function of aluminum foil is to insulate heat and plastic is to insulate water. the combination of the two can produce a reflective effect. The cement will react with the aluminum, but not the plpolished. It depends on how you construct it, but in general the price of this type of aluminum foil is relatively high. To reduce costs, some underfloor heating companies will advise you not to use it. , but you have to use it! Otherwise, it will seem like you spent less money, but in fact the floor heating company made money thanks to you, and the service life will also be affected!
