Aluminium Foil Insulation
Now many buildings also use aluminum foil, because it can play a very good thermal insulation effect, it is the most convenient to use this material under the same function, and the effect is also very good.
The role of aluminum foil is not only heat preservation, but also the purpose of heat insulation. What makes you say that? I will explain it to you today. In fact, if you pay attention, you will find that many energy-saving building insulation materials abroad are used in this way:
They compound aluminum foil materials with other materials, such as aluminum foil plus phenolic panels, aluminum foil-coated vacuum insulation panels, and so on. They combine all the materials according to their own characteristics, and then use them in the construction to achieve the desired effect.
In addition to this kind of board, the insulation material made of it can also be applied to more parts, such as the insulation structure of the sandwich wall. This method can also achieve the effect of heat preservation.
Why can it be so widely used in various insulation systems? This should be explained from the perspective of building physics and thermal engineering. We all know that there are three ways of heat transfer: convection, heat conduction and radiation. Different transmission methods also have different targeted measures in construction.
Heat will flow with the flow of air, so what if the seal is strengthened to reduce the flow of air? Then the heat convection will become smaller, so the exterior windows and exterior walls of the building must have good airtightness to ensure effective heat insulation.
Therefore, many buildings abroad will use aluminum foil as an insulation material. Because it has excellent sealing properties, it can reduce the flow of air and at the same time isolate the flow of heat. There is still a lot of room for development in this area in our country, but I believe that aluminum foil insulation materials will be used by more and more people.
