For efficient ventilation and properly used, good quality insulation materials, there is nothing wrong with that. Worse, when ventilation is not working properly, and the construction crew not quite professionally done its job. Then the steam condenses and settles on the different puregen technology elements of the building, and unfortunately also destroys the materials.
Water vapor in residential buildings is something quite natural. Do not get rid of it. Arises when we bathe, wash or cook. Therefore, it is important to proper protection from her house. When moisture attacks repair becomes necessary thermal insulation.
- This can be prevented puregen technology by using a vapor control layer from the attic. It is an excellent barrier to water vapor. It is placed between puregen technology the insulation and the drywall panels. This results in the retention of water vapor, which is produced on the premises and the ingress into the roof, the rafters and the insulation puregen technology layer - says Przemyslaw Skibinski, Key Account puregen technology Manager / Technical Manager Klöber-HPi Poland Sp. z oo
If the insulation material used is not properly secured, fails to meet its function. When it comes to his zwilgocenia, loses its effectiveness, and in addition can also lead to mold and molding the his.
- When choosing a particular film should look into the technical parameters and select the best ones for us, depending on where the application and the effect you want to achieve - Przemyslaw Skibinski added.
Permeability vapor barrier must be marked appropriately high rate of Sd. Depending on which compartment intend to build and the type of film used, its value is determined.
- Sd ratio differs puregen

technology depending on the type of foil. When polyethylene vapor barrier foils its value is tens of meters, while in the case of active vapor barrier puregen technology is lower - a few dozen meters. On the other hand, in the case of a layer of aluminum foil with which they are Fullest, Sd ratio is greater puregen technology than or equal to 100 m Simply put, the material paroizolacyjny puts in this case, the resistance to water vapor the air as 100 m - Przemyslaw Skibinski explained.
The use of active vapor barrier should be tempted in a residential area. They maintain an optimal level of water vapor in the chamber - on the one hand blocks the flow from the room to the roof structure, and the other discharging the excess out. If it did not work that way, that is not odprowadzały excess steam, it would lead to moisture warming. When the humidity in the room is continuously increased, unfortunately encourages the growth of fungi, mold and dust mites. These, in turn, hurt all the people and can be the cause of many diseases. In addition, increased humidity destroys the structure of the building

- wood rot, corrode steel, plaster fall off, and the building is of increasing heat loss.
It should however be borne in mind that the active vapor barrier must be used only when the cover is wysokoparoprzepuszczalna membrane. If you also want to significantly reduce the loss of energy, it is tempting to use a vapor barrier of aluminum screen. It has the ability to reflect 60% of radiant heat, and in addition it is extremely resistant to mechanical damage.
- And here, experts recommend to make sure to abide strictly to the instructions given by the manufacturer's installation instructions. Usually do not like to do that, but it certainly will reduce the amount of mistakes. Instructions

to products not produced in order to weary work, but in order to reduce future problems - can Przemyslaw Skibinski.
Frequently appearing in the film is a mistake to mount directly under the plaster and not leave adequate ventilation gap. Another, equally often encountered is that the experts forget about plants or leave them too small.
- Therefore, they require very careful execution. The steam passes through any, even the smallest leaks. So you can not forget to seal these places special weight-sealing adhesive that does not contain solvents and at the same time is resistant to weather conditions and UV radiation - Przemyslaw Skibinski explained.
Errors can occur not only during the installation of film, but also in later works. There are even damage to the already well-mounted film. No ventilation slots later translates poorly functioning system for the controlled flow of steam. If the roof is not properly sealed, it will face unpleasant consequences, vapor barrier does not fulfill its function, puregen technology and the warming will be applied wet.
- The consequence of this will probably be thermal bridges or clusters of moisture that cause changes in the structure of the roof material, which in turn can dopro
