Warming with polyurethane foam: reviews. Warming with polyurethane foam mansard, roof or walls of the house

Polyurethane foam is a unique material in terms of physical and mechanical properties, providing a high level of thermal insulation. It is widely used in various areas of construction, while the insulation with foam polyurethane reviews is exceptionally good. What is the reason for this?

Excellent performance

First, the use of polyurethane foam is effective, because in terms of thermal insulation it can be compared with vacuum insulation. In this case, our version is cheaper and simpler in terms of installation. Secondly, the coating on the basis of this material is characterized by elasticity, wear resistance and resistance to deformation. In addition, polyurethane foam can be used in any climatic conditions of independence from the temperature range. Warming with polyurethane foam has received positive feedback and thanks to the creation of a sealed impermeable to water and air layer. It is also important that the insulation is ecologically safe, therefore its application fully meets the requirements of sanitary standards adopted in the construction sector.

Many owners of private houses prefer the insulation of the attic with polyurethane foam. Reviews say that due to the economy and availability of material, it is possible to significantly reduce the cost of the construction process. High adhesion is a guarantee that the foam will be well sprayed or laid on any material - glass, plastic, wood, carcass or concrete, while it can be used for wall, ceiling and floor finishing. Thanks to the excellent grip, the use of fasteners is not required, which also greatly simplifies the installation process.

Today, insulation of the house with polyurethane foam (reviews confirm that this technology is the most convenient) can be carried out using several of its varieties. In the toughest version, this material consists of closed cells that provide high levels of hydro and thermal insulation. Most often this version is used for exterior walls, but it will require the creation of a ventilation system, since rigid grades of polyurethane foam do not differ in vapor permeability. Thanks to this method of thermal insulation, several purposes can be achieved:

• Ensure a high resistance of the coating to the effects of harmful substances, mold;
• Ensure adhesion to any surface;
• Protect the building from ignition;
• Use in any climatic conditions.

Simplicity in application makes simple and insulation of walls by polyurethane foam. The feedback of many of those who performed insulation on their own, say that this process can be coped easily and simply.

Home insulation features

To make your country house warm, reliable in operation and energy efficient, and at the same time reduce the cost of heating, you need to competently approach the process of its warming. One of the easiest ways is to insulate the house with polyurethane foam, so the load-bearing structures will maximize the heat inside the building. It is best to perform exterior trim to save usable space. Before finishing the walls, you need to do heat engineering calculations to determine the minimum thickness of the polyurethane foam layer. The calculations take into account:

• Resistance of load-bearing structures; heat transfer;
• Thickness of walls;
• Region of residence.

External insulation with polyurethane foam has received positive feedback due to the fact that the work is carried out conveniently and simply. At the same time you can finish the attic, balcony, balcony. Warming outside requires a number of works:

1. The surface of the walls is prepared.
2. It is applied by polyurethane foam.
3. The reinforcement is carried out with a special screed.
4. Finishing is in progress.

PPU is applied only on a clean surface, while its thickness depends on the type of wall and its condition. Reinforcement is carried out by means of a fiberglass mesh with small holes. Thermal insulation of the house with polyurethane foam has its own characteristics, which depend on the type of future finishing.

Siding or plaster?

If PPU is applied under siding, then it is required to create a hinged facade based on the frame and brackets on the wall. When applying the material, it is necessary to ensure that it falls under both the frame and under the guide profiles. This will provide high protection and reduce heat loss. With this method, the frame must protrude a couple of centimeters above the facade.

If the walls are insulated with polyurethane foam for further plastering, a slightly different technology will be required. When spraying, the texture and topography of the wall surface is repeated, so the application of polyurethane foam should be carried out neatly and evenly.

Warming of the attic

Warming the house with polyurethane foam has received positive feedback due to the fact that the materials can be used for finishing the entire country cottage. To reduce the level of heat loss, the attic or attic is most often trimmed with a polyurethane foam. What is good about this method? First, the seamlessness of the coating, which is provided by the use of a low-pressure apparatus, spraying the mixture onto a heatable surface. The PUF solidifies on the substrate for 10 minutes, with the operation being performed in several layers to achieve a smooth and neat surface. The material can be applied vertically and horizontally, while it is ideally attached to the surface of wood, concrete, metal or plastic. It is not by chance very often used to heat the attic with polyurethane foam. The reviews point out that this is the easiest and most convenient way to provide additional insulation.

This process must be approached responsibly in the first place because the attic is a dwelling room, which comes into contact with cold air more than other rooms. Accordingly, in addition to insulation, additional waterproofing will be required, which is carried out in accordance with the standards of environmental friendliness and fire safety.

The use of mineral wool and other tile materials - the process is too long and time consuming, so the insulation by spraying the foam polyurethane has received positive feedback just for the simplicity and speed of the process. With spraying, you can handle it yourself, with a coating life of about 50 years.

Features of roof insulation

PPU is widely used for finishing the roofing system, because thanks to spraying the material is perfectly held even on an inclined surface, repeating complex reliefs and shapes. Thermal insulation of the roof with polyurethane foam makes it possible to achieve high thermal insulation, with a smaller thickness of the material that will protect the surface from the cold. Due to the durability and good indicators of noise and thermal insulation, the PUF will be a good solution for any roofing system.

Filling PPU

Polyurethane foam is a unique material that fits on the basis of only two technologies. So, in the majority of European countries, for many decades now, insulation with polyurethane foam has been popular (reviews on technology are only positive), which is poured into a cavity up to 10 cm wide. The gaps are left specially to fill them with foaming materials that ensure a high level of heat and sound insulation. The whole process of warming is reduced to performing several types of work:

1. Outside or inside the walls, holes with a diameter of up to 12 mm and a set pitch of 60 mm are made.
2. Through the holes under pressure, polyurethane foam is filled, filling the cavity and climbing the height of the wall.
3. Filling is performed until the entire cavity is filled.

It is a convenient way to perform insulation of the house with polyurethane foam. The opinions of many agree that this technology makes it possible to make a seamless and sealed heat-insulating layer with the use of high-quality and environmentally friendly materials.

Advantages of Filling Technology

This method of using polyurethane foam is most often used in finishing multi-storey buildings for various purposes. The main thing is that the material should be laid evenly, excluding the possible appearance of cold bridges. This method is good, firstly, with minimal time, since no preparatory work is necessary. In addition, the hardening of the thermal insulation layer occurs gradually, so you can quickly fill.

Sputtering: fast and easy

Thermal insulation with polyurethane foam can be carried out by spraying it. This technology is widely used in most countries of the world. The essence of the technological process in the supply of two components to the nebulizer under the influence of pressure. Mixing, the mixture is removed to the surface and applied a thin layer on the surface. After a few minutes the foam sharply increases in volume, solidifies, after which a monolithic thermal insulation coating is formed. Depending on the type of components selected, polyurethane foam of different density can be used.

Low density PPU will lead to the fact that the coating will not be too resistant to mechanical influence, and therefore it is suitable only under the siding. A higher density allows the use of PPU for finishing surfaces that do not need additional finishing. The main advantages of the technology of spraying - in the processability, economic feasibility and convenience. On the basis of this technology, the attic is often insulated with polyurethane foam - the reviews say that this is the fastest way to cope with the insulation of this premise.
