Very often the question of the insulation of the walls occurs in private houses, especially if they were built with their own hands. In order to achieve the best results with minimal strength and time costs, you must use suitable materials. The best of them is at the moment building foam.
In order to insulate the walls in any house, it is best to use polyurethane foam. This type of foam is very quickly freeing, which allows you to get a dense surface in the watch, which separates the inner part of the room from external temperature changes, drafts and penetration of moisture.
Of the main characteristics of the foam allocate:
- Heat resistance – the material can withstand heating up to eighty degrees;
- able to skip water when necessary;
- the possibility of ensuring vaporizolation;
- high level of strength;
- increases in volumes after applying.
When using this material, you can not worry that the design of the walls can easily ignite, because the foam opposes this in every way anyone. With all the positive points of this material there are one negative moment in it. It concerns it the ability to stick. Ate to marry anything in a closed space, it does not freeze. In addition, the high cost of this product is not allowed to use a foam for insulation of walls in the house.
With constant contact with the aqueous medium, this material begins to deteriorate and over time it all comes to benumb. Foam application requires good ventilation, and therefore, it is necessary to create certain conditions for work. This material has low vapor permeability, so indoors are important to make forced ventilation.
When applying foam thick in four or more centimeters per meter square will need to use one balloon. In order to be able to work properly and without health risk, it is important to work using a pneumaticistole. This is a special equipment that helps evenly spray foam on a certain surface.
Such a gun mixes foam with gas and serves it on the surface, uniformly spraying where it is necessary. With the help of such a device, you can independently adjust the foam feed intensity for more comfortable work. Use a pneumatic equipment very convenient in operation, but not everyone resorts to it due to the high cost of such equipment.
When applied to the surface of the foam does not form any seams, which is convenient and aesthetic. This material has minimal thermal conductivity. An important indicator is its environmental friendliness – when used in the air no harmful substances do. Any impact on the foam will be painless for it, it reacts poorly only for ultraviolet radiation.
Warming room, it is advisable to take care of the sound insulation, what also copes foam. In addition, it has a good agsection with the surface. Foam easily applied to uneven surfaces, while the formation of air pockets is completely excluded. Fast hardening allows you to continue working after a day. Foam for insulation of walls is a universal and convenient option, with which even a non-professional can do everything well and efficiently, the main thing is to comply with safety.
Because the use of foam is becoming increasingly frequent, it will not be an increase in its species.
At the moment there are four types of mounting foam, including:
- two-component polyurethane;
If we talk about the mounting foam, it is a one-component substance that can be easily applied to the surface. There is such a foam in cylinders and is served out with compressed gas. For the insulation of the walls, this option is suitable for the least, because the applied layer has an open-type cellular structure that easily absorbs moisture and have a low thermal conductivity.
Use this type of foam recommended for small areas, which need to be closed, remove cracks, slit or eliminate drafts, and for a large amount of work it is necessary only a two-component substance. Two substances included in the reaction allow the finished material to foam and increase in volumes. Such cells already have a closed type and very quickly frozen.
A two-component mixture, which is also called polyurethane, is a kind of foam, which is the most suitable option for insulation of walls. Similar characteristics possesses and foaming, however, their compositions are completely different. When the foam is applied to the surface, the resin is mixed with the hardener, and the foaming process is due to the squeezing of air.
Industrial foam is a suitable material for the insulation of walls in any building. Such an eco insulation will allow no harm to get a maximum result. To fill a small profile, a simple mounting foam is suitable, but for large areas, the material must be different.
Two-component insulating foam will be the best choice for work on the whole surface of the wall.
Scope of application
Due to the variety of foam options, you need to know where it can be used. With the help of foamizol, it is possible to make heat insulation of the frame.
With it, you can fill the spaces between:
- walls both outside and inside;
- walls and plastic coating;
- walls and plasterboard coating;
- Floor and new flooring.
It is the use of wet insulation that allows you to create good protection of the facade of the house. All precipitation and external factors that will act on it outside, will not affect the quality of the material and will not spoil it.
Mounting foam is used to fix the plates, which are made of solid materials with good thermal insulation and it is filled with the seams between them. It can help when laying the foundation and ceiling device. With the help of polyurethane, it is best to close small cutters, filling the cavities when installing windows or pipes, helps this material and from cracks on the walls themselves.
Good results can be achieved with insulation using polyurethane foam frame house, its roof, attic, facade and even basement. It is very important for the winter to take care of all distressed places so that in severe frosts do not feel drafts and do not risk the integrity of the house, which can crack from large temperature differences.
Any repair work requires skills and skills, without which it is difficult to achieve good results. The same can be said about working with mounting foam. It is recommended to work with this material exclusively to those who know what to do with it and can work with him.
If there is no such possibility, then you need to consider several basic nuances that will help relieve work and make it more secure:
- Any work should be started with preparation;
- Before applying the substance, you must read the instructions and use protective facilities for face and hands;
- Finishing works require a certain procedure that should not be broken.
Planning to close on the walls of the hole, irregularities and cracks, there will be no big preparatory work. In order to put the foam where it is necessary, it is important to create a frame on the wall, which will be divided by straps on the compartments, each of which will be in turn filling. After creating a crate, it is necessary to pay the time to protective measures and will prepare for the use of foam.
It is advisable to purchase a special protective suit, have gloves and face mask. Very undesirable to allow foam to fall on the surface of the skin, because it will not be able to remove it with solvents or other substances and for a long time it will not disappear.
In the event that the wall is already finished, then two holes for the hose, in the middle and above are done for its insulation, and the process of filling emptiness begins up. Holes need to be stuck when they are no longer needed in operation, otherwise the foam will begin to flow. The substance is applied for a distance of thirty centimeters, after which there is a check of the expansion of the material in the cavity of the wall. If it is not enough, then you need to add a little more foam.
In a closed wall, it is difficult to see the state of filling the cavity and is almost impossible to understand when you need to raise the hose, therefore it is easiest to fix it to securely and remove after the full completion of work. For the final stage, the extinguishes of the full pouring of a material that can reach three days. It is very important to constantly ventilate the room so that fresh air circulates in it. When everything is completely dry, you need to align foam and then sew with a sheet of plasterboard.
If there is no need to use additional material, you can put the plaster on the aligned foam and bring it to the desired appearance of the finished surface. Frozening foam is obtained sufficiently tight, therefore it is not necessary to hide it at all, there are not terrible mechanical damage, because the immediate finish will be the most logical and inexpensive option. In the event of a fill of the slots upon completion of work, you need to remove the protection and eliminate the drums, if any.
Application of foam with their own hands is facilitated by using the appropriate apparatus, which helps to distribute the material between the profiles, which gives the best result.
Installing such profiles will be mandatory for any surface, whether it is a wall or ceiling. It is important that the foam came into contact with the frame and securely attached to it, ensuring the strength of the structure. Sprayed foam will foam in the course of work, so it is important to monitor the amount of material that is applied. It is best if the surface layer of the whole wall or ceiling will be as the same as possible, which will save from additional measures to align.
Each Master has its secrets in working with foam, which he does not give anyone, but for beginners they will not be so important.
In this case, it is necessary to clearly follow the basic rules and recommendations, which will help to achieve the desired result:
- Acquisition of mounting foam only in specialized stores, where they sell licensed goods with optimal shelf life. It is best to calculate the required amount of substance and buy everything at once. Quite often in such stores you can buy or even rent the necessary equipment for work.
- To work with foam, it is necessary to initially consider the ventilation system, because without high-quality ventilation, the hardening of the foam will be difficult and the quality of work will be weak.
- It is not necessary to work without a protective suit and masks, any ingress of the substance on the skin will be extremely undesirable, and it is especially dangerous if it falls on face.
- Before giving a large space, it is necessary to check the percentage of foam expansion to navigate the value of the layer to be applied to the surface.
Heat the wall with foam can with the necessary equipment, important knowledge and compliance with the rules of security. Starting the work of such a plan is better from close up of small slots and holes to learn how to work with a pneumatic equipment, understand the principle of applying material to the surface. For large volumes, it is important to build a cladding that will gradually fill.
Choosing a foam in the store, it is important to draw attention to what it is sold in which tanks.
There are a variety of options for their volume. This is necessary in order not to buy unnecessary if you need to close only one crack or hole, or not to gain a huge number of cylinders when the work has a lot. The choice of a particular brand is a personal matter, but it is recommended to acquire products of better-known brands. They follow the quality of products much more carefully.
