We produce roof insulation of the attic floor efficiently and quickly
Insulation of the attic is a complex undertaking, during which it is necessary to perform a number of tasks: to provide the room with heat, not to allow moisture from the roof to penetrate inside, to equip a competent vapor barrier, to preserve the usable area as much as possible for the comfort of residents. Often, the design of the attic has a complex configuration and it is not possible to insulate it with conventional thermal insulation materials. With the introduction of the use of foamed polyurethane foam for insulation of attic floors, it was possible to meet all the requirements.
The method of applying PPU - spraying - allows you to create a heat and waterproofing layer on any hard-to-reach surface, taking into account all the features of the geometry. The result is a monolithic spraying without seams and gaps, providing heat retention, moisture removal and noise absorption.

polyurethane foam
Insulation of the attic with polyurethane foam from the inside is the latest seamless technology for thermal insulation of the roof using sprayed polyurethane foam, and only the most positive reviews about this method can be found.
Polyurethane foam or PPU for short refers to a group of gas-filled plastics based on polyurethanes and consisting of almost 90% of an inert gas phase. PPU is a self-foaming and self-hardening mass used to insulate the roof from the inside.
This composition is sufficiently resistant to most organic solvents and can only be removed from the surface mechanically.
A significant disadvantage of PPU is that it is relatively sensitive to direct sunlight. However, despite this shortcoming, reviews of PPU can only be found positive.
Advantages of polyurethane foam
PPU spraying technology is the cheapest among all types of insulation
Guarantee against leakage of overlap joints and fastener
Fire safety D 1. Eco-friendly (certificate of contact with water).
Corrosion and decay bypassed PPU. Even rodents are indifferent to this material.
Service life of polyurethane foam is more than 50 years!
Temperature range from -200 to +200 degrees Celsius. Neither a fierce winter, nor a terrible heat are terrible for PPU.
The main advantage of PPU is its environmental friendliness. During the entire service life, it does not emit any chemicals.Widely used in the food industry, in footwear, sleep and leisure products. Including for children as it is hypoallergenic!
1 Features of attic insulation
Installing insulation for the attic from the inside, as well as insulating a well from concrete rings, is a much more complicated and time-consuming task than insulating an ordinary room. The difficulty lies in the following factors:
- the absence of a horizontal overlap from above - that is, it will be necessary to insulate directly along the inner surface of the roof, which usually has a triangular shape;
- low temperature in the attic in winter;
- it is possible for moisture to get inside, onto the surface of the insulation (this happens when the roof is damaged) - which not every insulator can withstand.
For these reasons, the use of most other materials, if possible, will become a very, very difficult task.
By the way, with regard to the relevance of the process itself: thermal insulation of the attic from the inside is needed not only in cases where it is planned to equip a living space. Even if you are not going to use the attic in any way, it still needs to be insulated.
The reason is simple: the lack of insulation leads to the fact that the temperature above the ceiling (that is, in the attic) in winter will tend to the street. In addition, inside, it is quite possible that it will also be damp - since the roofing often has leaks (and if it does not, then they may appear over time).
PPU spraying between the lags from the inside
As a result, moisture from natural precipitation will seep into the attic, spoiling the microclimate on it. Dampness, in turn, can lead to the appearance of fungus and mold, and they can appear not only in the attic itself, but also from the inside, in the living quarters of the second floor. This problem is especially relevant for owners of wooden houses with expanded polystyrene - after all, wood is most "afraid" of contact with water.
Why is there such a price difference in the market?
Reasons for the low price
Poor quality components
The main item of expenditure is the deposition components. Most often they save on them. They are characterized by the following properties:
- Components of low concentration (bodyage with solvent)
- Low flammability class G4 - low fire safety
- Component expiration date
Low pressure equipment
A strong sprayed layer is the result of mixing the two material components. The better the mixing happened, the better the sprayed layer will turn out.
Better mixing is achieved by high pressure equipment. You can save money by assembling your own sprayer. But the pressure in it will be 30 times less than necessary! The components will be poorly mixed and the spray layer will become unusable very quickly.
Unsuitable material parameters
The easiest way to save money is to spray the thinnest possible layer of material. But the thinner the layer, the lower the effect. You will receive a spraying service, but this service will be of little use, since the technological process is not followed.
In order for the spraying effect to be maximum, it is important to spray a layer of the required thickness. The parameters depend on where and under what conditions the spraying will take place!
Unskilled personnel
Cheap labor in the form of guest workers or students is a great opportunity to do cheap things. Allegedly trained employees will be able to competently independently select the pressure, material, distance from the material to the gun. Let me tell you a secret - there is no learning!
There is only the experience of a mentor, which is transmitted in the course of the student's work with the teacher.
Warehouse and company expenses
Some private masters mislead clients by calculating the costs of companies. Allegedly, the costs of maintaining a warehouse, accounting, and a team are the main ones in the final cost of work.
In fact, the cost of the work of one quality of a private master is an order of magnitude higher than the cost of the work of an organization.The quality that the organization guarantees a private master is unable to fulfill.
Average price and above
Certified Components
80% of the quality of the spray layer depends on the materials used. We use only certified factory components. Modern innovative materials significantly improve the quality of the sprayed coating.
The sprayed layer is strong. Meets all the declared characteristics!
High pressure equipment
The higher the pressure created by the equipment, the more technologically advanced the process of mixing the components, the better the sprayed layer is obtained.
We work with high pressure equipment. Hybrid heaters and heated hose bring materials to the correct viscosity before spraying.
Well-chosen material
Depending on the material to be sprayed and the environment, we select the components, set the viscosity, spray force. We control the layer thickness and brittleness. We strictly follow the technological process.
This approach is more expensive, but the effect of the work will be significant. It is cheaper to spray once and for a long time (>50 years).
Experienced team
As a company, we have been in the coating market for more than 10 years. Our team was formed even before the opening of the company, undergoing training abroad.
In total, for the entire period of work, we have insulated and waterproofed more than 27,000 m 2 of surfaces. There is no such type of object that we have not yet sprayed with PPU or polyurea.
We transfer the work experience from the senior master to the young ones and strictly control the quality. We answer to the customer with a ruble and the reputation of the company!
Contract guarantees
We are dealers of PPU and polyurea components. Often we buy components at good discounts. And we service the equipment ourselves, we have a base and a warehouse. Therefore, we can make good discounts even in season!
In addition, we conclude a legal contract for spraying services and give guarantees for the work performed!

Attic insulation in Legostroy
An attic is a floor located in the attic space and having a facade partially or completely formed by a sloping or sloping roof. Usually, the insulation of this room is a complex and costly procedure. The use of innovative technology of insulation by spraying polyurethane foam can greatly simplify this operation, and effectively solve the problem of creating a comfortable living space. Legostroy experts consider the possibility of complex insulation of the entire building as additional advantages of the sprayed polyurethane foam - the cold can no longer penetrate down through the ceiling - and savings on heating the house.
Attic insulation with polyurethane foam spraying is:
- unique characteristics of thermal protection: the coefficient of thermal conductivity of polyurethane foam is only 0.019 W/m*K. A 120 mm thick polyurethane foam layer replaces a 250 mm thick mineral wool layer;
- high speed of application of the material: only 1 worker with 1 spray gun is capable of processing up to 500 m2 of surface in 1 work shift. This means that a typical attic can be insulated in just 2 days. This is the fastest way to perform insulation of all currently existing;
- refusal of additional elements: internal insulation of the attic with PPU does not imply the need to install a frame, use fasteners, etc.;
- exclusive seamless technologies: PPU is applied in a continuous layer, without seams, which eliminates the possibility of the formation of cold bridges;
- proven moisture resistance: polyurethane foam does not absorb moisture and does not require the use of waterproofing and vapor barrier films in contact with beams and roofing. The material is vapor permeable;
- high adhesive properties: PPU is easily sprayed on horizontal and inclined materials of all kinds and is suitable for working with surfaces that have the most complex geometry;
- environmental friendliness: PPU does not cause allergic reactions, the material has antibacterial characteristics and is inedible for rodents;
- long service life: unlike mineral wool, which must be replaced once every 5 years, sprayed polyurethane foam serves its owners for up to 50 years.
The Legostroy company specializes in attic insulation using the PPU spraying method and has an impressive experience in optimizing objects of all purposes and levels of complexity. Legostroy specialists use high-quality materials from the best world brands and use the most modern high-precision equipment to create thermal insulation of the required density.
