Insulate the house with foam between the walls

The insulation of the house with the foam of the Insulation Works is one of the most important stages of construction. This applies to technical facilities and residential buildings. High-quality insulation can significantly reduce energy costs and extend the life of walls and finishing materials.

Styrofoam (PPU) came to the construction market recently, but quickly gained popularity among professionals and customers. This technology significantly reduces the time it will take. Mounting foam as insulation can be used on any surface, as it has high rates of adhesion and has virtually no limitations. Wall insulation can be done in three ways: The method is chosen based on the individual characteristics of the room and the calculation of the cost of work. But each of these methods, has its own characteristic nuances that need to be taken into account. Spraying and insulation with slabs is made both outside and from the inside of the house. And the filling is carried out in the airspace between parts of the partition, which is specifically left at the construction stage.

1. Spraying technology. Due to high adhesion, PPU instantly grips the base and creates an even layer in which there are no areas of cold inherent in most types of insulation. The foam insulation by spraying is done with the help of special equipment. It happens to be professional, and is used repeatedly, as well as disposable, which is quite suitable for work on their own.

If you need to insulate a small room, for example, loggia in the apartment, often used foam from conventional cylinders. It is somewhat different in consistency, but the base contains the same polyurethane. The application technology is similar to that of professional devices used by specialists, but is much slower due to low pressure in the cylinder. The mounting foam has a higher cost, but it is compensated by the fact that you do not need to buy equipment. As a result of the expansion, the insulation area fills completely. There is no need to level the walls before applying. High speed of work. Relatively high cost.

2. Filling technology. If the house is under construction and chose foam, you need a special construction of the walls, which provides an inner empty space, where the foam is filled. But even if the house is already fully built, insulation is possible, through special technological holes, which are drilled in several places, and on them pump foam. The device feeds the insulation on hoses inserted inside the wall. After the material is completely insulated, it turns out dense insulation, excluding air chambers. It has the highest efficiency and energy efficiency. The interior space is completely preserved and no additional exterior finish is required. Insulation of polyurethane foam with their own hands by filling is impossible without specialized equipment. Pumping through the holes does not preclude the formation of air bubbles inside. The pressure that the mounting foam creates when it expands can damage walls if the house is made of poor quality materials.

The foam is presented not only in a liquid state, but also in the form of ready-made plates. Insulation is made by sticking the segments to the surface and fixing them with dowels with a wide hat. Unlike spraying, this process does not require special equipment and can be performed with your own hands. In order to prevent the insulation from accumulating condensation, the surface must be treated with impregnation to prevent mold and fungus from appearing. This should not be done depending on which side the house is isolated from. At the end of the stage, the mounting foam from the cylinder is filled into the seams. Thus, insulation becomes monolithic. The lowest cost among other methods. Ease of installation. Insulation of PPU slabs is not so effective in terms of energy conservation. The house needs decorative decoration. For installation it is necessary to pre-align the surface, otherwise the insulation will lie unevenly. Foam in plates has a lower degree of durability.

Penoisol has a similar structure to PPU, but differs in technical characteristics. According to regulations, in premises with increased requirements for fire and environmental safety, such as: Public places. Kindergartens and schools. Medical facilities. Insulation of mounting foam is prohibited due to the light flammability and toxicity of products emitted as a result of combustion. This applies to both the slab version and the liquid version. Fire safety regulations allow the use of polyurethane only in private construction or in the construction of non-residential premises. In turn, penoisol complies with all regulations and has no restrictions on use. It is made on the basis of a complex chemical compound – carbamide-formaldehyde. It is a porous white material with lots of air bubbles. The main advantage of spraying Styrofoam over polyurethane – it does not support burning, and at high temperatures breaks down into carbon dioxide, nitrogen and water. The absence of toxic secretions allows the use of this insulation in any premises, regardless of their purpose.

Winter frosts come sharply, so you need to prepare for them in advance. After all, the onset of frosts is better to meet in the warm walls in the circle of relatives and friends. Mounting foam for insulation walls is used very often. It is applied on any surface with special pistols or pneumo-apparatuses. But you need to be able to properly conduct the procedure of insulation foam, so that the result was really tangible. Features of insulation For self-insulation at home foam requires the presence of a protective suit. Foam is usually sprayed from a cylinder on the entire surface of the facade, it is filled with voids between walls, rafters, bars.

The advantages of this type of insulation of walls foam in the air layer are quite a lot. The main ones include: vapor resistance; Fire resistance; The ability to increase in volume; Resistance to all sorts of mechanical impacts; the upper temperature limit remains within 80 degrees.

Often foam is used to make slits that remain after the installation of plastic windows. Due to this, the apartment also increases insulation. Pneumopistol is convenient to use for insulation not only windows and exterior walls, but also the foundation, loggia and balcony, pipes. The facade after the foam insulation for the walls turns out to be perfect – without visible joints and seams. One cylinder contains an average of 600 to 700 ml of composition, which is enough to handle a square meter with a layer of thickness of up to eight centimeters. It is very easy to work with such a gun: first a full cylinder is inserted into it, then you need to point it on the treated surface and pull the trigger. On average, the inflicted composition freezes during the day.

Penoisol. It contains aldehydes, which are harmful to health, although manufacturers often claim the opposite. Dries much longer than polyurethane (full drying time can reach three days). It is usually used to insulate attics, supporting walls and construction. It can be purchased in the form of ready-made plates or as a liquid composition. Ecowat and foam. It can be purchased in liquid form, more often used to fill the foundation. When finishing facades are practically not used because of the significant weight, which gives a large load on the walls. Also, not in favor of this material often speaks and high cost. Mounting foam.

Suitable only for sealing seams, joints, holes, as it does not miss moisture and vapor, and this is a critical moment for insulation material. When interacting with air, its volume increases twenty-fold, with a minimum number of air bubbles inside. You can buy in convenient cylinders of small volume, which have a significant shelf life. PPU or polyurethane. The most common option, which is considered and the most universal. The polyurethane insulation is very effective as insulation of facades. Comprised of two components, they need to be mixed by machine method just before application. The foam expands from the initial volume to thirty-forty times, inside formed small balloons. This achieves high-quality insulation at home.

Which variety to choose Will largely choose will depend on the specific situation, which area to handle. You can look at the most common cases when the house needs insulation foam:

If you want to fix the cracks or eliminate any other defects on the surface, the polyurethane will be suitable. But such material should not be exposed to sunlight. If you want to fill a large volume, then will fit foam. But the usual cylinder here will not be enough, you will need to buy a special device with high pressure. Buy it is not necessary – you can rent or borrow from friends, because often no one will use it. If you want to fill small cracks and carry out insulation on small areas of the area, you can buy a cylinder with the usual mounting foam. It does not support burning, after freezing is particularly firm, and it has an ecological composition. If the defects are found on the outside of the wall, it is necessary to apply the composition, the basis of which is polyurethane. It is applied in a direct way with the use of a special cylinder or apparatus.

It is worth remembering that the foam insulation creates an inside layer of errors that need to be eliminated. This will require a long hose, which you need to push the material inside. If you want to pour air layers inside the insulation, the wall makes holes with something sharp. The mounting foam is not suitable for insulating the entire external facade – it does not have the appropriate characteristics for this. Therefore, it is not necessary to choose it for this purpose, even though it is more economical cost.

Pros and cons Before you start insulating your home, you need to weigh the pros and cons. Of course, many people are interested in what the benefits of this method of insulation will be. These include:

Fast insulation speed, even if a large surface is processed; foam is not subject to biological influences, the wall is unlikely to appear mold or fungus; Flammable material: it can only melt at a temperature of more than 80 degrees; You do not need to pre-attach the frame to the facade – it saves both effort, time, and money; it turns out a monolithic surface without seams, which could penetrate the cold air; when the pipes or other metal elements are insulated, a fairly dense layer is created through which moisture will not seep through, there will be no corrosion.

You should not be exposed to direct rays; The inability to interact with water frequently The cost of the material: to insulate large areas will need to buy or rent special equipment; insufficient level of vapor ispermissability, will have to install artificial ventilation inside; you cannot perform the procedure without a tarpaulin suit, a respiratory mask with glasses and gloves. Of course, all this is unlikely to be found at home, and this is also an extra money spent.

People have long begun to insulate their homes with foam, but the ideal means of insulation has not yet been invented. Of course, the effectiveness of such a method cannot be challenged. The main thing is to buy high-quality materials. If you have the equipment to install, the process will not take much physical effort and time. After applying the foam composition and after its complete drying, the masters are advised to handle the surface of the facade with a special coating, which can be purchased in any construction store. This is required primarily to protect human health, and then to protect the insulation itself.

The price of the material also plays a big role in its selection. But on high-quality insulation is not worth saving if you need to insulate your home for a long period of time for a comfortable stay in it. Foam insulation is suitable for most walls, including panel, block and concrete. Therefore, they can be safely used as insulation for apartments and private houses. What kind of foam to choose – it is a purely personal matter of everyone. But at first it still does not prevent to learn more about the chosen composition, read reviews, get advice from the seller in the construction store. It is not recommended to use a filling insulation, which easily lights up as opposed to a foam fireproof version. And in use it is not the most convenient, the exception is only the surface of the floor.

Insulation with liquid foam is a better solution, because this procedure can be carried out independently if desired, without resorting to the help of specialists. If you do everything right and be careful, you will be able to quickly insulate any surface that needs it.

Is the cylinder foam used to insulate the walls inside and outside the house? The foam is used to insulate the walls of houses inside and out. There are types of material that have their own application features, certain drying times. The main criterion for insulation is the absence of cold bridges. Foam for insulation walls is the best option to create a comfortable, comfortable stay and dryness in the house. Because it is hermetically sealed on the surface, there will be no cracks to get cold air. Is it possible to insulate the foam wall.

It is widely used to insulate walls outside and inside. Apply with a special device or a gun. The material fits well on the vertical, horizontal and sloping surface. Features of wall insulation: Walls become thicker, leading to greater resistance from environmental impacts. The material can withstand temperatures of up to 80. Permeability. Resistance to various injuries. It won’t fall, it won’t deform. The material doesn’t burn. Insulate such objects: window sorms; Walls from the street; The foundation balcony, attic; Pipelines attic rooms. After application, there are no stitches and joints. The foam freezes from 1 to 3 days, depending on the number of layers applied.

Before you start building a private house, it is worth thinking about the issue of insulation not only walls and ceiling, but the entire structure. These activities can be carried out not only during the construction phase, but also during the operation of the building (it is better to do it in the warm season). If the residential building will have unsatisfactory insulation indicators, it will negatively affect not only the people living in the house, but also the building itself. All members of your family will be prone to frequent colds. Life in cold rooms will not be comfortable. The walls of the house will be subject to freezing, and then the appearance of mold and fungus on them. If all the structural components of the building will have increased thermal conductivity, this will cause the self-destruction of building materials. From the above, one conclusion arises: the apartment building should be insulated. And how it can be done should be decided by each homeowner individually. You can insulate the house with one of these materials: Foam for insulation walls: the views and features For insulation walls modern masters use for work a variety of materials and technologies. They have significant differences between them, but they are all designed for the same purpose – to make insulation at home as productive as possible. Liquid foam for wall insulation is called stopoliuretan (PPU). All the necessary ingredients are mixed in factory conditions and the composition necessary for polymerization is under high pressure in cylinders. In order for the reaction of churning and hardening, it is necessary to contact this composition with oxygen.

Applying foam to the surface of the walls Waterproofing Installation foam is also used for waterproofing. It under the influence of moisture increases in volume and hardens during the day. Mounting foam with waterproofing properties is sold in cans. It is endowed with high waterproofing and fixing indicators. It is used for both external and internal works. This versatile material is not afraid of water and high humidity, so it finds widespread use in everyday life. Output Foam insulation can be used for walls made of various material, including concrete, blocks and reinforced concrete panels. Therefore, they are used to insulate private cottages and apartments. Before you give preference to any one of the types of foam, consult a specialist. If you have decided to insulate the house with liquid foam – this is the right intention. Raw materials always try to buy the best domestic and foreign producers. So you will be able to avoid premature wear and tear.
