Ceiling vapor barrier is now being done more and more frequently during renovations. It can be done using both old time-tested methods and modern materials.
For example, you have a damp and damp room, although it is quite warm. It can be a heated basement in a private household or a bathhouse. For such premises, very often a characteristic moment is the formation of steam, that is, warm air, which contains droplets of water. He has nowhere to go, so he exits through the ceiling and walls. And due to the fact that steam is constantly formed, there is a slow destruction of these surfaces. This is the cause of very unpleasant consequences, even shrinkage of the house is likely. It turns out that the vapor barrier of the ceiling is important, as it allows you to avoid the penetration of steam into these surfaces, which is the cause of furtherdestruction.
The oldest and most proven way is to use polyethylene, which does not allow any vapor to pass through. A good option is non-perforated polyethylene, which does not allow steam and air to pass through. However, he has a minus - it is difficult to be in such a room. Vapor barrier of the ceiling can be carried out using modern materials. For these purposes, you can use special mastics. If they are applied to the ceiling, they will conduct heat and retain moisture, while the surfaces will not collapse. The ceiling must be treated with such mastic before finishing is carried out. If we talk about how to put a vapor barrier on the ceiling, then it is worth noting that there is a more modern way, which is based on the use of a special surface with a pile. The villi pass heat well through themselves, retaining wet droplets. Such material is often used for vapor barrier of concrete ceilings, as well as mastics.
Vapour barrier of a ceiling made of wood can also be made using special mastic. Such a building material has a huge advantage - it is not in danger of ignition. In the modern construction market, in addition to mastics, you can find the widest range of various vapor barrier materials: penofol, isospan, alucraft, armofol and others. All these materials are quite convenient in terms of installation, reliable and able to serve.a very long time. If we talk about how to put a vapor barrier on the ceiling, then it is worth noting that all these types are laid on the inside of the floors. They need to be fixed as tightly as possible, with the side on which there is a polymer coating, inside the room to be finished. Greater reliability of the entire structure can be given by sealing the seams. A small gap, about five centimeters, should be left between the facing panels and vapor barrier materials. If you have enough skills, you can do everything yourself.
