The main pros and cons penoizol - the newest material for insulation

click fraud protection

Penoizol Once the do not call Penoizol - "liquid foam" CFR "Mipora", "Mettemplast" - but no one will undertake to say what it is, where applicable, and what properties characterized.But these products are, if you know about all of its features and intricacies of using technology to help solve a lot of problems, and with minimal costs.

So what is Penoizol interest and whether it is for us in terms of domestic use, especially if you focus on such an important indicator as the ratio of the final result and for your buck?Consider all of the major pros and cons, which is characterized by Penoizol.

basis of the material is a polymer (resin urea, purified in a special way), composed of various additives are introduced (in the first place - a plasticizer).These include and substances such as foaming agent, curing agent and water.Technology of preparation penoizol has its own specifics, but it's a topic for another article.We will understand only with its advantages and disadvantages.

It should be noted that opinions on this very controversial, but the information is not so much.And this is understandable - a fairly new product on the market.Therefore we confine ourselves to summarize all the reviews that are available in the public domain.

Pros

According to this parameter, as the coefficient of thermal conductivity, superior Penoizol common mineral wool.Its value may vary between 0.033 - 0.048 W / m · K, because the value depends on the density of the material (8 to 28 kg / m³).Then, under the same conditions of insulation CFP can be laid over a thin layer, which is not a significant impact on reducing the usable space in the room.





drenched mass forms a solid structure.Therefore, in a layer of insulation there are no joints, gaps and overlaps, as is the case when using MDF and rolled products.Accordingly, there is no need for sealing of their (base sealing).

Thanks yield penoizol it can process any part - difficult, with complex geometries or relief.With insulation of private buildings particularly difficult just finishing places is passing through the wall (ceiling) of various communications, location of pipes on the roof, and so on.

Penoizol plus lack of fasteners ensures the integrity of the waterproofing layer, eliminates the possibility of the formation of the so-called "cold bridges".Thus, indirectly, further reduced the level of heat loss.

According to some experts (with reference to the profile SRI RAS), the life of the material is unlimited.Although the practice (taking into account the "youth" of the product), it is not confirmed - Only theoretical calculations.

Penoizol not melt, non-flammable, it does not emit smoke - only char.

Its structure is such that it applies to "dyshashih" category, so unpleasant "surprises" in the form of mold or fungus base material is not threatened.

Possibility reinforcement layer by introducing a mixture of additives of mineral origin.

Low Cost - from 790 rubles / m³ .This is enough to insulate about 15 - 20 m² (depending on the filling thicknesses).

Cons

Like all foams are not characterized by high mechanical strength.Therefore, insulation penoizol automatically accompanied by a surface cladding applied layer.And it is not in his appearance.For example, it is not essential in interior decoration of the garage.The reason for the fragility of the material."Unprotected" Penoizol quickly crumbled, and the good of this insulation will be small.

complexity insulation frame designs.If the mass of the fill is made between capital partitions, they under her weight is not deformed.Consequently, Penoizol fills the entire cavity of the maximum.And with insulation when the formwork wall hard enough, they can "play".After some shrinkage CFP it will lead to the formation of voids, and to rectify the situation then does not work.While this is possible and to avoid.For example, maintaining the room temperature at a constant level and the constant, thereby regulating the intensity of evaporation.But it is feasible only for internal works.

foam

Penoizol emit harmful substances , and intense.That's one opinion.Other - only partially, and then only to the complete solidification drenched masses.

Restrictions on use - should not be used for thermal insulation of underground parts of structures.The same applies to different types of ties (equip for "wet" technology), as part of the moisture in the material still absorbed, which impairs its properties as a heater.

complexity independent of the work.The main difficulty - in the strict observance of technology, and this requires some knowledge and experience.

But it's mostly theory, and in some respects is not entirely confirmed.After application penoizol practice on a large scale, and for a long time, not yet.Accordingly, the lack of any The accumulated statistics, specific recommendations for the use of the material, taking into account all the nuances of such a method of warming.Therefore, before making a final decision on whether the acquisition and installation of their own hands, we must all be carefully considered.And even better - to consult with the "pros."

In fairness it should be pointed out that many manufacturers advertise other varieties penoizol - crushed (packed in mats) sheet.But this is a bit different, and more like an ordinary foam (in pellet or slab).
