Specifications penoizol, its properties and disadvantages of both insulation
There is a heater, which has many names, various manufacturers call it penoizol, yunipolom, miporoy, mettemplastom.However, the essence remains the same - the insulator is a modified foam has several advantages.So, Penoizol, the characteristics of which will be discussed later, not only copes well with the main task - insulation.He also is not afraid of fire, and does not contain any harmful ingredients.Because of its special composition, this eco-friendly material compares favorably with conventional thermal insulators.If its application is possible to reduce the cost of construction, without losing quality.

On the composition penoizol
This heater is similar to the candy or marshmallows.It is easy enough to manufacture and economical, since the raw materia
To make this insulator take one of the varieties of urea resins, adding a special acid and blowing agent.Strictly certain parts of these components are placed in the unit in which compressed air is brought.It allows you to get in the end fluffy frothy mass which immediately until frozen, used to fill cracks and voids.Pena, who had just emerged from a sleeve device is white and jelly-like consistency.She tightly fills air gaps, does not burn and well warms design.
Fill penoizol on the surface of the attic.
Hardens fresh foam immediately.First, after 10 or 15 minutes after its manufacture, it only lightly grasped.Hours after 3 or 4 foam becomes hard, but still not very strong.The strength she gets a couple of days (and sometimes have to wait 3 days).During this time Penoizol finally dries up, getting all their remarkable properties in full.Thermal performance is superbly and costs at the same time - very small.Incidentally, as compared with other materials, the speed of installation of a heater increases to 4 or 5 times.A possibility of using lightweight construction promises penoizol promising future.
Worldwide, this material is widely used today, and consumers appreciate penoizol properties.
In terms of application to the surface, the warmer than it resembles a polyurethane foam, the properties of which have been considered in the article: Features and specifications of polyurethane its advantages and disadvantages.

about the ability to conduct heat
Thermal conductivity of the insulation is very low - it coefficient ranges from 0.031 to 0.041 watts per meter per Kelvin.If pave the wall just desyatisantimetrovyh layer of material in the house at once will become warmer.Due to this heating system will cost several times cheaper.So all the costs associated with warming, are fully compensated for one winter.Penoizol layer may be from 5 centimeters to one meter.How is it to be, the landlord decides.
About resistance to fire
Flammability penoizol defined as T-1, and a group of flammability - B-2.This means that this material compares favorably with most polymers - he not only illuminates, but do not even melted by fire.By the degree of opacity of the group he was awarded the D-1 and toxicity - a group of T-1.Use this heater can be in a wide temperature range from minus 60 to plus 80 degrees Celsius.
Imagine this situation: the ambient temperature is such that even melted metal.What will happen to penoizol?Do not worry - he just quietly evaporate without giving off any harmful substances.As for the smoke, when it is allocated an open fire is 10 times less than that of styrofoam (foam).

about chemical and biological resistance
Many are afraid of mold thermal insulation, covered in a wet environment with black patina.But Penoizol no fungus does not take, as, indeed, and other microorganisms.Mice and rats gnaw adoring several moves in a heater, and do not touch Penoizol.It is absolutely not responsive to organic solvents and chemically aggressive environment.So, they can safely insulate attics to basements - your products do not threaten.
About moisture absorption
Penoizol absorbs water well, but also gives it without any consequences.In this he differs from the better side of mineral wool, the quality of which after wetting and drying deteriorates.A penoizol though that - it had dried, the same holds heat well.Moreover, it absorbs no more than a 1/5 of the moisture, then evaporating it.Therefore, where the material is used, the walls will not syret but also ventilation space must be provided.Otherwise, mold and mildew can not be avoided.
Since Penoizol hygroscopic, the insulated walls of the room they are able to free "breathing".It provides a comfortable environment for people living in the house.However, for the walls themselves is very useful - they are slowly destroyed.During the day, the insulation absorbs moisture from 10.5 to 20 percent.
air passes through the structure, insulated penoizol.At the same humidity in the room is regulated by itself, without any outside influence.To live in such a house is very comfortable - with a constant influx of fresh air, and the optimum ratio of heat and moisture in it.
Strength of Materials Group
foams highly manufacturable due to its special softness.Due to this they are well fitting for all the irregularities of the building structure - quite a bit of material trample.Therefore, no gaps or voids are not formed, and the insulation layer is "at height".But the strength or bending penofol has a very weak and breaks from a small effort.Now list the specifications penoizol strength.Thus, when applied thereto linear ten percent strain, the compressive strength will be in the range of from 0.07 to 0.5 kilograms per square centimeter.Flexural active component will be from 0.1 to 0.25, and the tensile - from 0.05 to 0.08 kilograms per square centimeter.About
by experiment, during which studied durability penoizol, it was found that the insulation applied on the structure of the vertical type, able to last 30 to 50 years.This is confirmed by the data obtained by analyzing the use of polymers similar in construction.

About minuses penoizol
course, one of the pros, no building material can not contain.And buyers wonder where is can be a trick.So, this substance is poured into the cracks and openings does not increase its volume.Conversely - its shrinkage is from 0.1 to 5 percent.But only if done correctly.And if the master hands do not grow out of the place, it is of low quality and raw materials can be used, and installation is not the most perfect.
In this photo you can see the result of hacks.There
reviews, saying that Penoizol during drying unpleasant smells, releasing toxic substances.This can happen only when used cheap urea resin, which should not be used.Dishonest contractors can save on raw materials, and using outdated plant for the production of the material.Such cheap model is not capable of injection molding.So remember: if Penoizol unpleasant and strong smell, then you are simply deceived.
And about the harmfulness say the following: during the polymerization of the material a certain amount of gas with a specific odor is released.This formaldehyde.Naturally, they can hardly be called useful.But many paints and lacquers which smell strong and unpleasant.A Penoizol once completely dry, no longer exude any odor.Incidentally, the manufacturers have assured that the allocated material formaldehyde have a very low concentration.The hygienic certificate confirms this.However, the choice is yours - you can take a natural insulator, if in doubt.
So, we can conclude that the main disadvantage of this heater is the pursuit of profit unscrupulous manufacturers who are taking worse and cheaper raw materials and technology do not comply.And we pay for it with you.Sometimes the firm stating that long and successfully produce Penoizol also produced the marriage.So watch out!
