Rating of the best liquid thermal insulation for 2022

Building a house is not an easy task. And here it is not only a matter of choosing a suitable site, drawing up a house plan and erecting walls. It is important to make the house warm and cozy. The choice of material for thermal insulation is an important component of construction. If earlier it was easier to make a choice, because the assortment was not so great. Now technology has taken a step forward, the old technique has been replaced by a replacement in the form of liquid thermal insulation.

What is liquid thermal insulation

Liquid thermal insulation, or as heat paint is also called, is one of the types of insulation, often used to insulate walls, pipes, roofs, and facades. By its consistency, this material resembles mastic or sour cream. Such a heater is applied in several thin layers, before applying a new layer, it is necessary to wait for the previous one to dry completely. After drying, each layer will resemble foam, this reaction occurs due to contact with air.

The basis of thermal paint is usually made of acrylic, as well as various additives in the form of microspheres of ceramics, glass or silicone. A certain type of additive is suitable for its field of application. Due to the presence of spheres that contain air, heat is reflected. The presence of acrylic guarantees the stability of liquid thermal insulation.

Types of liquid thermal insulation

Liquid thermal insulation can be divided into two large groups. The first group of goods includes heaters, which are thermal paints, and the second group includes heaters with foam filler. Let's look at the features of each group.

• Thermal paint

When applied, the thermal paint forms a film that has thermal conductivity. This is ensured by its structure, which contains various fillers. The method of its application is quite simple and does not differ from conventional paint coating. But one layer will not be enough, because. it can easily wear off or be destroyed by the environment. Therefore, for a good thermal effect, at least 10 layers of paint are required. Such a heater is applied to any surface, does not require additional skill and anyone can handle it. When working inside the building, it is better to use protective masks.The paint dries quickly enough, but several layers are required, and during the entire process you can inhale the chemicals that make up the paint, which can adversely affect your health.

• Foam insulation

In appearance, they resemble mounting foam. The basis of such thermal insulation incorporates a polymer, which, upon air contact, forms a dense material. It is applied with the help of special spray guns, when applied it seems liquid, but due to its high density it quickly adheres to the material. After 30 minutes after application, it begins to form a light crust, and after a few hours it begins to harden. This type of insulation is often used by construction companies, it does not have a negative impact on health.

Rules for applying liquid thermal insulation

Wall insulation

For wall insulation using liquid materials, a heater with ceramic components is more suitable. Water-based liquid ceramic heaters are ideal for interior wall coverings, and for exterior facades, a lacquer-based option is suitable. With the help of such material, you can easily insulate hard-to-reach places and do the work yourself.

Before starting work, prepare the surface. To do this, you need to remove all the irregularities and, if necessary, plaster using a dry gypsum mixture. After you need to apply a primer. When the wall is fully prepared, you should start mixing liquid insulation. Mix it immediately before application and follow the manufacturer's instructions. Thermal paint is applied in several layers, it is allowed to form a new layer after the previous one has completely dried. Also, the layer of paint should be about 1 mm thick.The number of layers depends on the material and thickness of the walls. You can apply the product with a foam roller or spray, then there will be a uniform coating.

For external wall insulation, it is necessary not only to level the surface, but also to get rid of mold and fungus, then treat it with a special antiseptic. After that, the wall is primed. When the primer dries, you can proceed to thermal insulation. The weather during work should be warm, in the presence of wind, rain, it is forbidden to apply thermal paint. The layer of applied paint should be no more than 1 mm. In the work it is recommended to use a brush or a spray gun. Each layer dries for about 24 hours. Complete drying of the final layer depends on the number of applied layers.

Floor insulation

To reduce heat loss, it is allowed to insulate the floors with liquid thermal insulation, this option goes well with the underfloor heating system. But this method can be used in rooms where there is no floor heating.

Before starting work, clean dust and dirt, remove all irregularities. Then a primer is applied in the form of acrylic impregnation. After it has completely dried, you can apply thermal paint. It is best to use a spray gun here. You need to keep it at a distance of 50 cm from the floor, you should work at one angle. Then the paint will have a uniform distribution over the entire area of ​​​​the floor.

Pipe insulation

Liquid thermal insulation is used for insulation of pipelines in the gas and oil industries, as well as for water supply pipes. Such a coating reduces heat loss, and also provides protection against chemical and mechanical influences. For this, a special line of thermal paints is produced, designed for pipes.

Before starting work, remove dirt and rust, then prime the pipe.After the primer has completely dried, you can begin the process of warming. Ceramic thermal paint is applied with a brush or a special sprayer. It is necessary to apply about 5 layers, each layer dries about 4-5 hours. After that, the pipe is covered with a special enamel.

Selection rules

First of all, you should decide on the place of application of thermal paint. Usually, a jar with a product is labeled by the manufacturer. Carefully look at what surface this product can be applied to.

Carefully inspect the contents of the jar. It should be homogeneous, there should be no plaque or any inclusions. It is desirable that the color be white, but light shades of gray or beige are allowed. Otherwise, the product will not meet the declared qualities.

The density of the product must not be ignored. A low indicator of this criterion will give a large heat transfer. In addition, you should familiarize yourself with the service life and interaction with external environmental indicators. For example, ultraviolet, fire or water.

Not all liquid thermal insulation has an easy application method. Make sure that the product not only meets the desired protection and density indicators, but is also convenient to use.

Since there are a large number of manufacturers of this insulation on the market, it is better to give preference to a time-tested brand. So you can be sure of the quality and reliability of the purchased product.

The best liquid thermal insulation

AKTERM Concrete™
