What insulation is better for the walls of a wooden house inside: TOP-9 rating of popular materials

When building a dwelling, many are interested in what kind of insulation is better for the walls of a wooden house inside. There are many different materials on the market, they can differ in type, quality, flammability and ease of installation. Also, the price can vary greatly. Therefore, it is necessary to understand which products are worth paying attention to, so as not to lose heat and not spend a lot of money and resources on heating the room.

When building a wooden house, it is imperative to provide for the possibility of insulating the room. This can be done from the outside or from the inside (although, in some regions it makes sense to do this from both sides at once). Then the heat loss will be much lower. Today there are several of the most popular materials that are often used for internal insulation. It is worth considering in more detail the better to insulate a wooden house inside.

Jute

Usually, there is one weak point in wooden houses - these are inter-crown joints. It is through them that most of the heat leaves. Thus, they need to be carefully caulked inside and out in order to reduce the cost of heating the room. In this case, it is recommended to use jute. This material is inexpensive and has excellent wear resistance. The tape must be untwisted and fixed with brackets. Then the next crown is laid, and so on. This material is used along the entire length of the timber even at the construction stage. If you ignore this recommendation, you will have to significantly increase costs after putting the facility into operation.

Important... As the wood dries, new cracks will appear. Therefore, it is required to choose the correct thickness of the jute. Care must be taken during styling to avoid breaking the fibers. Otherwise, the material will break.

Specifications:

• suitable for inter-crown joints;
• low thermal conductivity;
• different material thickness.

Styrofoam

Today, many people use polystyrene foam as internal insulation. This is a very cheap material that also has excellent sound insulation. It is worth noting that ordinary foam will not work, you need to buy a special one, which is designed specifically for insulation. Its difference from the simple one lies in a special treatment that reduces the flammability of the material. This material is easy enough to cut with a knife and fix to the wall, since it is sold in slabs. Excellent water and vapor repellent properties.

Important... Styrofoam is a combustible material. In case of fire, it releases toxic substances.

Specifications:

• low thermal conductivity;
• excellent insulation.

Penoplex

This material is similar to foam. It is also made from expanded polystyrene. However, the technologies differ, as well as the properties of the insulation. This option is considered more effective today. Penoplex is often used in regions with a harsh climate for interior decoration. The material is relatively inexpensive, it is possible to carry out installation quickly, since the insulation is produced in sheet form. The durability is high enough that plaster or paint can be applied. The weight is light and the service life is about 40 years.Vapor permeability is low, so it is imperative to provide a high-quality ventilation system.

Specifications:

• high flammability;
• low vapor permeability;
• service life is about 40 years.

Slag wool

This is a very popular material that has been used for a long time on the market. It has a low price, but it can hardly be called environmentally friendly. The fact is that during production they use waste from the metallurgical sphere of production. That is, it is necessary to create high-quality floors after installing the insulation so that it does not affect people's health. Recently, slag wool in slabs has been sold. It has excellent flexibility, so it fills almost all gaps well. Low thermal conductivity. It also provides good sound insulation. It is important for wooden houses that this material prevents the appearance of rodents and insects. But it is necessary to understand that the material absorbs moisture well, after which it loses its shape and properties.

Specifications:

• soundproofing;
• thermal insulation;
• afraid of water;
• available in slabs and rolls.

Penofol

When deciding which insulation to choose for a wooden house inside, many prefer penofol. It is not an environmentally friendly material. But it is very high quality. It has reflective properties and protects the house well from heat loss. However, when using it, it is imperative to use a sufficiently powerful ventilation system. There is a division of penofol. Category A is made from aluminum foil. Category B has double-sided coating, while C has foil on one side, and a self-adhesive surface on the other, which greatly simplifies the installation process. No personal protective equipment is required when working with this material. It is pleasant to the touch. The layer is quite thin, which is an important advantage. You do not have to provide for a large gap between the walls in order to qualitatively insulate the structure.

Important... This material does not allow radio waves and other waves to pass through. On the one hand, it protects the person. On the other hand, there may be problems with finding a cellular network.

Specifications:

• foil and polyethylene with balls filled with inert gas;
• available in rolls;
• does not let heat through.

Glass wool

Today it is one of the cheapest and most popular materials, which is often used to insulate wooden houses. It can be found in almost any specialty store. Products are manufactured by various manufacturers. The main element is molten glass. Dolomite flour, borax, limestone and a number of other components are added to it. Polymers are responsible for ensuring that all of these elements are securely connected. Since there are rather long glass fibers, the quality of the insulation is much higher than that of a number of other types. Vapor permeability and low thermal conductivity are the main advantages of this material. Available in rolls, mats and slabs. Thus, you can choose the most convenient material for installation.

Important... When working with glass wool, it is strongly recommended to use personal protective equipment so as not to damage the skin and mucous membranes.

Specifications:

• non-combustible material;
• low thermal conductivity;
• the term of use is about 30 years.

Izolon

This is a versatile insulation that is in demand in the domestic market. Its cost is about 70 rubles per 1 sq. meter. Thus, the price is adequate. But the efficiency is very high. Practice shows that isolon can become the best insulation of the 21st century. It is distinguished by its durability (service life of about 70 years), itself is pleasant to the touch and is highly flexible. That is, it is not a problem to mount it. A foil coating is provided here, which increases the wear resistance of the material. It also helps protect people from radio waves and other radiation. Water absorption is zero, which is an important advantage. Insulation does not emit harmful substances if the temperature does not exceed 100 degrees. Rodents and insects do not start in it. And over time, rot and mold do not appear.

Specifications:

• service life is about 70 years;
• low thermal conductivity;
• zero water absorption.

Ecowool

At the moment, ecowool is considered the safest insulation of those offered on the market. At the same time, it has excellent characteristics. The material practically does not transmit heat and perfectly tolerates external factors. In production, 80% of cellulose is used, as well as additionally used antiseptics and fire retardants. They reduce the flammability of the material and prevent rot, destruction by insects and rodents, as well as other deformation as a result of external factors. Good sound insulation is an additional pleasant bonus. The material is sold in bags and slabs, so you can choose the best option based on whether you plan to insulate the walls, floor or ceiling. However, friable material must be applied using special equipment, which significantly increases the cost of work during the construction of a house. If you do everything manually, you will have to spend a lot of time and effort, since you need to compact the material well.

Specifications:

• environmentally friendly material;
• soundproofing;
• low thermal conductivity;
• sold in slabs and bags.

Stone wool

It is a versatile material that can be used for indoor and outdoor use. It is in high demand in the market, so it is easy to find it in many specialty stores. Average cost. But the service life exceeds 50 years. That is, if you need a reliable insulation, then it is worth buying stone wool. Products are created from various rocks based on basalt. The material is not flammable, it perfectly tolerates temperatures up to 600 degrees, without emitting harmful substances. Thermal conductivity is one of the lowest. Sold in rectangular slabs that are easy to assemble. Depending on the manufacturer, there are various modifications in the form of additional coating with foil, fiberglass, and so on. This increases the price, but also improves the quality characteristics. The insulation does not break and is subject to deformation from external factors.

Specifications:

• thermal conductivity 0.036 W / (m * K);
• non-combustible material;
• not subject to external factors of influence.

These are the most popular insulation materials that are used today for interior decoration in the construction of individual wooden houses. They can be found in many hardware stores. It is worth noting that it is necessary to pay attention not only to the type of insulation, but also to the manufacturer, because they actively compete with each other, I offer products of various quality.

How to choose the right insulation for indoor use in a wooden house

When choosing a material, you should pay attention to several parameters at once, namely:

• service life, since it depends on when it will be necessary to change the insulation;
• flammability and release of harmful impurities into the air during a fire;
• water permeability, since some materials, when exposed to moisture, lose their quality characteristics;
• the form of release, since it is not always more convenient to use sheets, sometimes it is necessary to buy material in rolls;
• cost, since the price depends on what material can be purchased in a particular case.

It is not always profitable to contact the manufacturer directly because most large firms provide goods to retail buyers at retail prices. It is better to study the offers on the market. Perhaps one of the official dealers provides a discount on products.

And you also need to check for a safety certificate and a fire certificate. This will once again make sure that the product is of high quality and original, and not a fake.
