Roof insulation foam house is very young method developed by construction companies. To implement this method of insulation is necessary to have special equipment to work and have the necessary skills to perform the work themselves.
Currently, liquid heaters, designed to work indoors and are Penoizol penopoleuritanovaya foam. Use of these materials provides fast and efficient execution of tasks, in contrast to those materials which require prior preparation and imparting a desired size.
Modern types of house construction involves the use of a heater in the form of a foam that fills the space formed between the wall panels "sandwich" type.
Some prefer to use the cheaper option of insulation - assembly foam. But not everyone knows that its purpose is limited to the application to eliminate the small cavities.
What is polyurethane foam and how to work with him?
Polyurethane foam is a substance made by combining a polymer - polyol and polizotsionata. Their union occurs only when you are ready to conduct thermal insulation works and has no influence of air currents. Self material distribution process on the working surface takes place by means of a spray.
Foam bases overgrowth occurs due to unreacted substance with carbon dioxide. The foam is applied to insulate the roof with special equipment - a compressor and spray gun.
Such insulation is very strongly attached to the surface and increases mass many times. It is great walled preformed slit, irregularities and defects of the walls, forming a rather dense and hermetic coating.
The positive properties of the material
- Do not miss the heat.
At the expense of a part of the substances deposited on the working surface of the material is increased and forms in its a plurality of air spaces of the cavity filled with carbon dioxide, which prevents leakage of heat energy.
- Good coupling with the surface.
Insulated material not depending on the material surface and its location forms a bond not demolish it.
- It fills even the most hard to reach space.
Due to this property, there is no need to perform any preparatory work for the application of the material.
- It creates a soundproof effect.
Dried and processed material is able to absorb any, even the loudest sounds preventing their penetration into the living room.
- Does not penetrate and spread a result of scattering.
In order to support the material, various metal constructions, but applied foam ensures their complete security and isolation from the impact of the water factor.
- There are no seams.
Since the material is applied by spraying, it has a smooth surface appearance without joints and seams.
- It can be used for thermal insulation constructions of any complexity.
If you have any difficulty in using sheet insulators, replace them with liquid, as they are applied to absolutely any kind of surfaces.
- Not affected by fire.
Due to the content in its composition a fire retardant material in fire self-extinguishing. The foam began to burn it is necessary to influence the temperature more than 500 degrees.
- Light.
By forming the porous layer, the foam is lightweight and does not impose excessive load on the work surface.
- Not be exposed to germs.
Its properties completely prevents the appearance and propagation of harmful environments.
With such a list of positive qualities, this material does have competitors, because it contains negative points and to use.
The negative properties of the material
- The high price category.
- Before the work should fully protect parts of the body to avoid the foam contact with skin.
- To work requires skill and editing skills.
- In combustion emits pair toxic to the human body smoke.
As applied polyurethane
Polyurethane foam is applied to the surface as a heater special gun directly on the supporting structures and lathing. When she plays the role of solidification uteplitilya and waterproofing.
Filling the voids.
It is used between the masonry. Apply
in the empty space hose in such places increases and hardens shielding housing from exposure to low temperatures and fluids.
Use a pre-prepared slabs of foam.
Buy such sheets of building materials stores, and the process of getting there is in the specialized enterprises.
Which is better - Penoizol or polyurethane foam?
In order to understand what kind of material the highest quality and strong, you need to compare them.
- The thermal conductivity of the assembly during installation of insulation.
In this case, the polyurethane foam has been ranked as his koffitsient greater than that of UF foam.
- Density.
Just win foam. Unlike penoizol it is harder and has a higher density structure.
- Resistance to liquids.
Do not allow the liquid to penetrate into the structure of the high density polyurethane foam material, the first material, on the contrary, is inclined to moisture and its absorption.
- Resistance to fire.
Penoizol refer to materials which do not ignite, and the foam is subject to melting and release of harmful substances.
- Life time.
In this category, both materials are equal, the best of their lifetime is about 50 years.
- Price.
Penoizol bit cheaper polyurethane foam.

What is Penoizol?
A process for preparing this material is different from obtaining foam in that it is based on the production of urea polymer which is exposed to chemicals, whereby it as well as the polyurethane foam swells in many times. In appearance, this material is very similar to the familiar man foam.
Properties penoizol:
- It has a low level of density in the hardened state.
- It has a good indicator of the thermal conductivity, which allows you to save heat in the living room. Penopoleuretan but has a much greater indicator of the preservation and maintenance of the room temperature.
Since the substance is in the solid state is not quite high density, it is not often used for insulation those surfaces which may be subject to different mechanical stress or varying degrees load. Also, do not use it for thermal insulation of basements and any other where humidity index higher. Penoizol not strong enough to withstand the effects of moisture.
The most common material is Penoizol, when it comes to insulation of the walls of a frame house, roof, the inner area of overlap roofs or for positioning between the material presented in the form of bricks.
The transition from the liquefied state to a solid takes place rather quickly, it takes time no more than half an hour. But further work is necessary to postpone the execution of about 2-3 days to achieve the best effect.
This material is advantageous in that, after the acquisition of its hardness may be compared with monolithic materials. Many who used Penoizol to create external thermal insulation layer dwellings were satisfied. This material provides a wall material completely protect against freezing, the effects of air streams and liquids. If spraying substance occurred correctly on its surface will not form the different defects in the form of microcracks.
Execution of insulation works should take place under favorable weather conditions. In order to perform the desired manipulation of workers have to pay them about 150-200 rubles per square meter of insulated penoizol. Also it is not okonchatelnoya amount since it will depend on what the customer chooses to layer thickness and what would be the working surface.
To save a little on labor payment, it stands on its own to prepare the surface, which will be warm. And, it is, clear of litter and debris, to provide a state of dryness and lack of dust particles.
consumer reviews
Oleg, 30 years, city Nizhny Novgorod.
"On the advice of a friend decided to treat the interior of the basement, which is strongly freezes in winter frost. He invited specially trained construction team, which was a great experience and a steady supply of customers. The work carried out perfectly, the material is completely arranged for me. Next year I plan to bring the same brigade to insulate the roof. "
Vladimir, 40 years, city Moscow.
Penopolipropilenovoy foam newly crafted exterior walls bagasse. It would be desirable, of course, do all the work on their own material and apply a little bit different, but the vast Internet I read a lot of positive information on this matter and decided to do the work for them. Hired people who did everything at the highest level for the day. I paid the same amount of money that would be spent on basalt wool, but still in negative territory would remain, because the work he would have done. "
