Types of heaters for inside walls - the main species

To house kept the warmth, it is necessary to create good thermal insulation using a variety of materials-utepliteley.Uteplyat house inside is only recommended in cases where there is no access to the outside walls or the owner does not want to spoil the outer appearance.In some cases, produce the outer insulation is simply impossible when the outside wall borders on the elevator shaft.

Properties and types of materials for thermal insulation of walls inside

All materials with which will be wall insulation should have a number of properties:

• high resistance to temperature changes;
• high temperature resistance and non-combustibility;
• durability;
• low heat and thermal conductivity (it will give an opportunity not to use a large amount of insulation);
• moisture;.
• vapor permeability, etc.

In the market there is a large amount of insulation material, but due to its quality, these heaters are used most often: mineral wool, expanded polystyrene and polyurethane foam.

Mineral wool

Mineral wool has a low cost and has a number of positive qualities.The disadvantage of the insulation can be considered only that the walls, which will be warmed with its help have to be covered with plasterboard or other material (to create a false wall), for bargain aesthetic appearance.Buy mineral wool slabs can be, and can be rolls.Plates are well suited for small spaces and rolls - for large.

How to insulate the walls with mineral wool?

whole process of heat insulation can be divided into several stages: preparation of the components, mount them on the wall, the isolation and the hidden layer.

Initially, the wall cornice mounted ground, and its lower part is secured with dowels or screws.Stack wool need several layers (three, and possibly four).If you use the boards, then attach them with glue if rolls - with screws or pressshayboy.

The next step is to create a vapor barrier.This will prevent the ingress of mineral dust to the people and will not allow moisture to adversely affect the insulation.The best material for the vapor barrier is a vapor barrier.It is designed so that it can pass air only outside, especially if the moisture does get to the mineral wool, it will erode or evaporate over time.

At the last stage of the insulation can be hidden with the help of drywall or other materials used in the decoration.

Wall insulation using styrofoam

next type of insulation - polystyrene, which is a great advantage of light weight, and when compared with mineral wool - great moisture resistance.Expanded polystyrene is divided into two types: extruded and foamed.They differ only in the manufacturing process, but have the same properties.Another advantage of this material is that when mounting it on the wall is not necessary to use the framework or other mounting structure.Attach you can use glue or dyubeli.Nebolshoy negative - the need to isolate the joints between the sheets of insulation.Typically, this is done with foam.

The first step is to align the walls to the maximum, as well as to treat the wall with a special coating that will protect against the formation of mold and mildew.After coating, it is necessary to wait at least a day.Then you need to prepare the mounting materials.If the glue, it should be quite thick.Using a ruler, measure off and cut the required part of the styrofoam.

In the next step, go to the attachment process.With a roller (or other object) must be carefully put on the wall.Apply the adhesive to hold the bottom up.Next, attach to the walls of polystyrene plates so that formed between the T-shaped joint.After the insulation is attached, it is necessary to close the space and design to settle for at least 2 days.

If you want to fix the insulation with dowels in one plate needs to be done 6 holes: two in the center, and the rest at the corners.The dowel holes are driven, as in the past - plastic nails.If the joints are formed between the plates more than 4 cm, it is necessary, they need to seal the strips of expanded polystyrene.smaller joints are filled with foam, which does not contain toluene, to avoid damaging the material.Remains of foam should be cut, and the remnants soak glue, to protect against mold and mildew.
In the next step, the entire height of the premises is necessary to glue the reinforcing mesh.On the insulation is applied to a thick layer of glue, then the grid sits on it.It is important that the mesh joints do not coincide with joints polystyrene.On top of the grid and must be treated with glue, and after drying to align with sandpaper.

At the final stage, the wall plaster is applied, and if you plan to hang wallpaper - primer.You can also set the framework for walls different wall panels.

Polyurethane foam Polyurethane foam is considered the most reliable material for thermal insulation of the interior of the walls.It is applied using a special apparatus, which are mixed polyol and poliizotsinat.During mixing foam is formed which subsequently is applied by spray onto the walls and solidifies.For its application, as in the case of rock wool, also need to be installed on the frame walls.

The big advantage of this type of insulation is no need to fix it, and that can cover a large area and thickness of the layer can be adjusted in a short time.Polyurethane foam after application does not leave any gaps, as well as perfectly retains moisture.

Before finishing work carried out, a layer of insulation must be plastered using a nylon mesh.

After curing the polyurethane foam has a number of positive characteristics: it will last for decades without additional maintenance, increase fire safety in wooden houses, as well as withstand the thermal and mechanical stresses, temperature fluctuations.

What to choose?

to insulation has been high quality, this procedure should be carried out during the warmer months.It is necessary that the wall was as dry as possible.To reduce moisture, the walls dried heaters or heat gun.

When used to insulate the frame can be uneven walls or wall coverings.For the frame, you can hide the communication pipes or wiring.To fill the frame is best to use mineral wool, as due to the elastic, it clings tighter.The adhesive foam is cheaper than installing frame.

Mineral wool does not burn.In the case of exposure to fire it does not emit dangerous gases.The foam can withstand flooding, it almost does not absorb water.

to not freeze the outer wall, not unstuck wallpaper, not dropped out and did not appear condensate mold, apply liquid insulation inside the building.

can use foam glass - it does not get wet, vapor permeability and good sawed.The foam is inferior in quality.Foam glass is not illuminated and is durable as compared with penoplastom.A sealing surface finish and operate in the same way as for the foam.
