Rating of the best liquid thermal insulation for 2024

Building a house is not easy. And here it is not only about choosing a suitable site, drawing up a house plan and building walls. It is important to make your home 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 technologies have taken a step forward, replacing the old method with a replacement in the form of liquid thermal insulation.

What is liquid insulation

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

The base of the heat 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 application. Due to the presence of spheres that contain air, heat is reflected. The presence of acrylic guarantees the durability of liquid thermal insulation.

Types of liquid thermal insulation

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

• Warm paint

When applied, the heat paint forms a film that has thermal conductivity. This is provided by its structure, which contains various fillers. The method of its application is quite simple and does not differ from coating with ordinary paint. But one layer will not be enough, because it can easily wear off or be destroyed by the environment. Therefore, a good thermal effect requires at least 10 coats of paint. Such insulation is applied to any surface, does not require additional skill and anyone can cope with it. It is best to wear protective masks when working inside a building. The paint dries quickly enough, but several layers are required and during the entire process of work you can breathe in the chemicals that make up the paint, which can adversely affect your health.

• Foam insulation

In appearance they resemble polyurethane foam. The basis of such thermal insulation is composed of a polymer, which forms a dense material upon contact with air.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 with liquid materials, insulation with ceramic components is more suitable. Liquid ceramic insulators with a water base are ideal for interior wall covering, and for external facades, the option with a lacquer base 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 irregularities and, if necessary, plaster using a dry gypsum mixture. Then you need to apply a primer. When the wall is fully prepared, you should start mixing liquid insulation. Mix it immediately prior to application and follow the manufacturer's instructions. The heat paint is applied in several layers, it is allowed to form a new layer after the previous one has completely dried. Also, the paint layer should be about 1 mm thick. The number of layers depends on the material and wall thickness. You can apply the product with a foam roller or spray, then there will be a uniform coverage.

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

Insulation of floors

To reduce heat loss, it is allowed to insulate floors using liquid thermal insulation; this option is perfectly combined with a warm floor system. But this method can be used in rooms where there is no floor heating.

Before starting work, you should clean up dust and dirt, remove all irregularities. Then a primer is applied in the form of an acrylic impregnation. After it is completely dry, you can apply thermal paint. It is best to use a spray gun here. It must be kept at a distance of 50 cm from the floor, working at the same angle. Then the paint will be evenly distributed over the entire area of ​​the floor.

Insulation of pipes

Liquid thermal insulation is used to insulate pipelines in the gas and oil industry, as well as for water supply pipes. This coating reduces heat loss, as well as provides protection against chemical and mechanical stress. For this, a special line of heat paints is produced for pipes.

Before starting work, remove dirt and rust, then prime the pipe. After the primer has completely dried, you can start the warming process. Ceramic heat paint is applied with a brush or a special spray gun. It is necessary to apply about 5 coats, each coat dries in about 4-5 hours. After that, the pipe is covered with special enamel.

Selection rules

First of all, you should decide on the place of applying the warm paint. Usually, the can with the product is marked by the manufacturer. Look carefully at what surface this product can be applied to.

Examine the contents of the jar carefully. It should be uniform, 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 should not be overlooked.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 indicators of the environment. For example, ultraviolet light, fire or water.

Not all liquid thermal insulation is easy to apply. Make sure that the product meets not only the required protection and density, but also is 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.
