"Penoplex" for floors is used more and more often today. This is due to many factors that are expressed in the positive features of the materials. In the production process, extrusion technology is used, which allows to achieve a finely porous structure. Each of the cells is isolated from each other, while the size of each can vary from 0.1 to 0.2 millimeters. Inside the material, they are evenly spaced, which ensures heat resistance and strength.
Moisture resistance reviews
"Penoplex" for floors is chosen by consumers for the reason that the mentioned material absorbs moisture minimally. If the insulation is immersed in water for a month, then moisture will be absorbed in a small amount only for the first 10 days. After that, the structure ceases to receive moisture. At the end of the term, the volume of water in the plates is no more than 0.6% of the total mass. Thus, experts note that moisture can only penetrate into the outer cells, which were damaged during cutting.
Insulation Reviews
"Penoplex" for floors performs its main task - insulation, as buyers emphasize. If we compare this heat insulator with others, then the thermal conductivity of the first is much lower, its value is 0.03 W / (m ° C). Home craftsmen note that they use this material even in rooms that are operated at high humidity. At the same time, the thermal conductivity remains unchanged, it can vary from 0.001 to 0.003 W / (m ° C). That is why experts recommend using Penoplex for insulating attic floors. This is true for foundations with basements and floors. In this case, you do not have to use an additional moisture barrier.
Reviews on vapor permeability and service life
"Penoplex" for floors is so popular among the modern consumer also because of the low vapor permeability. This indicates that the material is characterized by increased resistance to vapors. If you use a layer whose thickness is 2 centimeters, then the vapor permeability will be equal to 1 layer of roofing material. All buyers who have been using the described thermal insulation for more than one year note that with repeated freezing and thawing, the characteristics of the material remain unchanged. The manufacturer guarantees the service life of the insulation for 50 years or more. Deadline will depend on proper installation, performance and external factors.
Reviews on compression andinstallation features
If you decide to use Penoplex floor insulation, you can count on high compressive strength. This indicates excellent strength characteristics. Even large loads are not able to change the dimensions of the material. Home craftsmen prefer "Penoplex" for ease of processing, it can be cut using a regular knife. Plates can be used for insulation even in difficult conditions, when work is accompanied by snow or rain. Thus, the insulation does not need to be protected from the weather.
Reviews on environmental friendliness and reactivity
Today, "Penoplex" for floor insulation is used quite often, many choose it because of its environmental friendliness, which is at a high level. Despite the fact that freons are used in the production process, they are absolutely safe when exposed to fire, do not destroy the ozone layer and are not poisonous. "Penoplex" for the floor, reviews of which are presented in the article, has almost zero chemical activity. Most chemicals used in construction do not react with this type of insulation.
It is impossible not to mention the bioresistance of the canvases, so the plates do not decompose and do not rot.
What does the master need to know when using "Penoplex"?
In order to keep the size and shape of the paintings unchanged, it is necessary to withstandpermissible ambient temperature at which the described heat insulator can be operated. As a rule, this parameter is indicated in the material passport. If the insulation is exposed to excessive heat, then the characteristics and dimensions of Penoplex may change, it can ignite and begin to melt.
Using floor insulation on logs
This option is used for wooden buildings that were built using a column base. The insulation is laid on the ground surface between the floor joists and the surface. The process should be divided into several stages, the first of which involves the dismantling of the floorboard. If necessary, the next step will be the installation of new logs. To continue the work, a waterproofing layer is being equipped, insulation is being laid, and at the final stage, floorboards are being installed. It is necessary to dismantle the old boards if the thermal insulation is planned to be laid not at the construction stage, but in a residential building.
After all the boards are raised, they need to be analyzed for the presence of putrefactive formations. If the elements are in poor condition, it is recommended to replace them with new ones. In the process of installing new bars, it is necessary to start from the most extreme element. In this case, you need to use the building level. After that, a beam is installed from the opposite end, a thread is pulled between the elements, along which the rest of the beams will be mounted.
Featuresworks
After the preparatory work is completed, you can start warming. "Penoplex" for the floor, the thickness of which should be 40 millimeters, is laid according to technology. The process starts with laying a layer of waterproofing on the beams. The edges of the material should reach the central part of each log. Waterproofing is fixed using the building level. From above, the master must lay the Penoplex plates, excluding the coincidence of the seams in one place. The resulting gaps are filled with construction foam. As soon as it was possible to fill all the seams, the material can be fixed with dowels or special building glue. Wooden boards are nailed on top.
Use of insulation followed by screed
If you decide to use Penoplex for underfloor heating, then after laying you can equip the underfloor heating system. Gravel of 40 cm is laid evenly on the surface of the soil. The material must be compacted, sand should be laid on top. The thickness of the backfill should be slightly less than the previous layer. This figure is usually 10 centimeters. The sand must also be carefully compacted.
At the next stage, a concrete screed is poured over the ground, but first you need to lay the reinforcing cage. After all the above manipulations have been completed, you can begin to insulate the floor. To begin with, waterproofing is done, then Penoplex is laid, the next step will be pouring a concrete screed. If "Penoplex" is used for the floor under the screed, then this option is the most optimal solution. Howeverunderfloor heating mats must be laid before pouring concrete.
At the final stage, the finishing floor covering is set up.
Recommendations for work
For waterproofing, it is recommended to use a fairly dense polyethylene that can withstand temperature extremes and high humidity. The cost of this material is quite acceptable. It is important to note that it is unacceptable to lay waterproofing on a wet concrete surface, as this may cause a violation of the thermal insulation characteristics of the material.
Conclusion
If you decide to use Penoplex for floor screed, then it is important to observe the dressing of the seams. This will provide moisture protection and durability. Speaking of the above, it should be noted that a fiberglass mesh is stretched on top of the insulation. This is necessary to strengthen the concrete screed and protect it from cracks and other damage during the maturation and operation of the solution. Whatever method of insulation you use, you should be guided by the presented technology, which will be the key to success in carrying out the work. It is also important to prepare all materials and tools, the presence of which will allow you not to be distracted from work.
