The innovative technology of insulation with polyurethane foam is the best suited for thermal insulation of the roof. Our company offers services for spraying a two-component polyurethane foam mixture. We are ready to work with roofs of any type and size, as well as with non-standard solutions. The fact is that the features of the spraying technology make it possible to carry out thermal insulation even in the most difficult conditions, while not reducing the quality of the work performed.
Practice shows that high-quality roof insulation can significantly reduce energy consumption. Moreover, in the case of insufficient roof sealing, in the cold season, condensation may appear on the surface, which will not only contribute to the appearance of harmful microorganisms, but also gradually destroy construction and finishing materials.
As for polyurethane foam, it penetrates into absolutely all hard-to-reach places and guarantees complete insulation. Work can be carried out both on a flat and on a mansard and pitched roof of a residential building, an outbuilding or an industrial facility.

Technology advantages
- Roof insulation with polyurethane foam does not imply the dismantling of the old coating, which will save money, effort and time.
- Polyurethane foam can be applied to any surface configuration, since the material has high adhesion rates.
- High speed of insulation, which reaches up to 500 square meters per day.
- Low coefficient of water absorption, which is extremely important for the roof.
- The structure of the material allows air to pass through well, which contributes to the normalization of the indoor microclimate.
- Polyurethane foam is not a medium for the development of insects, rodents and pathogenic microorganisms.
- Low coefficient of thermal conductivity, allowing you to keep cool inside the house in the warm season, and warm in the cold season.
- The porous structure further enhances sound insulation.
- The possibility of insulating both the outer and inner sides.
Advantages and disadvantages of polyurethane foam
The advantages of PPU are:
- Incombustibility.
- No reaction to water vapor, splashes, practically does not absorb water.
- Excellent adhesion to any materials. (exceptions - polyethylene and fluoroplastic, wet surfaces).
- Excellent thermal conductivity, low reaction to temperature changes, no temperature changes in properties.
- Elastic structure, excluding the appearance of cracks during shrinkage and other deformations of the substrate.
- Complete cut-off of the treated surface during application.
- Lack of insects, rodents, birds.
- Does not rot, does not react with contacting elements.
- Durable, manufacturers declare service life of 30 years, but in practice, the PPU works longer.
However, there are also disadvantages. These include:
- High price.
- High manufacturability of application, the need to use special equipment.
- The applied layer must exceed 5 cm, less thickness will not provide effective work.
Caution!
It is afraid of ultraviolet radiation, which does not allow its use in the open form. The rate of destruction of polyurethane foam from sunlight is about 1 mm per year. At the same time, complete destruction does not happen, the process does not go deep into the material. The problem is eliminated by painting or decorative PPU fencing from direct sunlight.
All the advantages of the material have been repeatedly tested and confirmed in practice, and the disadvantages are quite easy to eliminate.The high cost of PU foam as a material is compensated by its self-sufficiency, which allows significant savings on the purchase of a double layer of waterproof membrane.
Incombustibility is achieved by adding halogens to the original components, which makes it possible to classify polyurethane foam as a fast-extinguishing material. If there is no open fire, PPU cannot ignite in any way, therefore, it can be considered completely safe in this respect.
As a result, we can conclude that roof insulation with polyurethane is not only efficiently, but also profitable.
A really indisputable fact is the need to use a spraying device, although it is difficult to say if this is a drawback, or just a feature of the application.

If you attract specialists who will work with professional installations, then there is no need to purchase disposable kits. In this case, the quality of the coating will be maximumand mistakes caused by lack of experience can also be avoided.
WATERPROOFING WITH POLYUREA
The price for waterproofing with polyurea depends on:
- the thickness of the layer of polyurea and the applied polyurea;
- the scope of work on surface preparation (grinding, dedusting, washing);
- the need to apply UV resistant enamel;
- and many other factors ...
| Waterproofing with polyurea Huntsman or Basf | Roof waterproofing | Waterproofing of floors, parking lots | Waterproofing foundation, plinth | Waterproofing of tanks, containers, pools |
| Spraying polyurea with a middle layer of 2 mm | from 1500 rub / m2 | from 1500 rub / m2 | from 1500 rub / m2 | from 1500 rub / m2 |
Polyurethane foam: what is it, its main characteristics
Polyurethane foam is a subtype of gas-filled plastic. The material contains only about 15 percent of solid components, the rest of the volume is made up of gas bubbles. Thanks to this combination, the material is considered the best heat insulator and is quite in demand in the construction industry.
Types of polyurethane foam
- Elastic PPU - rolls, layers of foamed heat-insulating material made on the basis of plastic. Its density is no more than 20 kg / m3. Due to their open structure, the air in the cells moves freely, as a result, the material is able to restore its original shape after bending. The bulk of this material has a density of 8 to 15 kg / m3. Elastic polyurethane foam is used for external, internal insulation of roof slopes. Also, this type of polyurethane foam is distinguished by increased noise insulation characteristics. The heat insulator is placed between the rafters in strips of a specified size.
- Rigid PU foam — thermal insulation material based on foamed plastic. Its structure is characterized by the presence of small closed cells. Solid components make up about 3 percent, do not deform due to the structure of the material. Rigid polyurethane foam is characterized by increased resistance to chemical and mechanical stress, has a relatively low weight. The density of the material can be from 30 to 60 kg / m3. The cost of installation work will depend on the thickness of the thermal insulation layer being equipped.
Roof insulation with PU foam is much cheaper than the use of mineral heat insulators with a similar thermal conductivity. The final cost of insulation works will depend on the thickness of the insulating layer, the area of the roof slopes. Professional roofers recommend making a layer of polyurethane foam insulation from 5 to 10 cm.

Characteristics and features of polyurethane foam
Polyurethane foam is a type of gas-filled plastics, with a minimum solids content of up to 15%, the rest is occupied by gas bubbles. Thanks to this combination, an excellent thermal insulation material is obtained, which is widely used in construction.
According to their main characteristics, there are three types of this insulation:
- Solid polyurethane foam with a density of 40-80 kg / m3. Produced in plates, sheets.
- Soft polyurethane foam with a density of up to 40 kg / m3. They are produced in the form of a sprayed coating.
- Foam rubber - in rolls.
Hard varieties are used as thermal insulation and sound insulation, soft ones - in the form of padding and coatings in industry and in everyday life.
Polyurethane foam sheets can be produced both uncoated and coated. As protective layers, paper, foil, fiberglass are used, which are applied on one side.
The undoubted advantage of polyurethane foam is the possibility of spraying directly onto the surface, excluding the stage of manufacturing, installation, fitting, etc. This feature distinguishes polyurethane foam from other heat-insulating materials practically by the absence of any special and labor-intensive preparatory work, the insulator forms a high-quality and durable insulating layer that is not exposed to external influences, does not absorb moisture and does not lose its properties over time.
Due to its high adhesion, PU foam can be used on almost any surface - wood, metal, glass. It can be perfectly sprayed on both vertical and horizontal surfaces. Due to the high service life, according to some sources up to 50-60 years, it does not require renovation or repair.
PUF is characterized by low moisture permeability, the higher the density of the material, the less moisture it absorbs. One of the substances that make up the polyurethane foam, due to which moisture permeability is reduced, is castor oil.
It is also important that this insulation is practically non-flammable, which is achieved by adding various halogens and flame retardants to the mixture. Polyurethane foam burns only in the presence of an open flame. The features of this material can also be attributed to the ability to prevent the spread of flame, since when exposed to fire, PPU is coked.
For thermal insulation, you can use a cheaper foam, but it is important to take into account that this material can deform at the slightest mechanical stress, in contrast to polyurethane foam, which is not subject to any deformation and does not lose its integrity. Thus, the insulation of the PPU roof is the most expedient solution.
The main methods of application include the method of pouring and spraying:
- Most often, the pouring method is used for frame structures and buildings. It consists in filling the space between the rafters. Perfect for insulating a roof of a complex shape, since the insulation fills all possible cracks and cracks in the structure. It differs from spraying in that no air is supplied to the mixture, a jet is formed at the exit, which, falling into the cavities, fills them, giving a certain shape. This method is suitable for creating polyurethane foam boards, sandwich panels. It is recommended to fill in several layers, with a time delay for drying each layer.
- The second method differs in that the polyurethane foam is applied already in a foamed form. The constituent ingredients isocyanate and polyol are mixed with air in special installations. The mixture is pumped under pressure into a spray gun and applied to the desired surface.This method is more expensive, since special equipment is needed, but due to the speed of filling and drying, as well as the effectiveness of thermal insulation, the method completely pays for itself. Advantages of the spraying method: high sound insulation, absence of seams and dew point, high adhesion, quick drying of the composition - it hardens within 3 seconds. Equipment for polyurethane foam application is of two types - high and low pressure.
Note! At high temperatures, PU foam foams better, which makes it possible to use material more economically. Therefore, it is best to carry out insulation work in the warm season.

Benefits of polyurethane foam
In the modern construction market, there is quite high competition, therefore, the same high requirements are imposed on any building materials, in particular heat-insulating materials.
Important! When purchasing insulation for roof slopes, it must be borne in mind that it will be exposed to numerous adverse natural influences, for example, moisture and temperature extremes.
Material advantages
- Light weight... The weight of PPU is much less than many other insulators, therefore it is widely used on old, dilapidated structures without dismantling the roof.
- High resistance to environmental influences. The material is not afraid of moisture, ultraviolet radiation, fungal attack, chemical influences, does not burn. It retains its thermal insulation characteristics even when exposed to atmospheric precipitation. The operating period of the insulator can be up to 50 years.
- Effectiveness of application... Thermal insulation of roof slopes with polyurethane foam helps to reduce by almost 20 percent the financial costs of heating a house during the winter period of operation.
- Low the cost... Thermal insulation works are much cheaper than using other insulation materials, for example, mineral wool.
What is polyurethane foam and its benefits
Insulation spraying method is best suited for roof insulation.
Polyurethane foam is a substance made from petroleum products. Its foaming occurs due to mixing of low-boiling liquids. In the course of a chemical reaction taking place in this system, a certain amount of heat is released. This energy converts the liquid into a gaseous state, as a result of which the material swells.
Today, polyurethane foam is used to insulate residential, civil and industrial facilities.
This insulation can be prepared directly at the work site by mixing its structural elements and then applying them to the prepared surface. This thermal insulating material can also be sold as rigid, semi-rigid and elastic boards. They are obtained by extrusion, casting, pressing. But for roof insulation, the method of spraying insulation is still suitable.
