What materials can be used for interior insulation

Under wallpaper, the primary types of insulation are:

1. Plaster mortar with thermal insulation properties. They have several types of filler:

• based on sawdust. Eco-friendly, but not suitable for rooms with high humidity (balcony, bathroom);
• made of polystyrene foam. Excellent noise suppression and thermal insulation. But not fire-resistant and easily flammable;
• in the form of perlite or vermiculite (mineral base). Fireproof, but not moisture-resistant;
• foam glass.

1. Cork – environmentally friendly and safe. This type is durable, has sound insulation, heat insulation, hides wall defects. Minus – the price is above average.
2. Roll – Polyfoam, made of foamed polyethylene. On one side, the material does not have an additional coating, and on the outside it is covered with special durable paper. This allows you to glue different types of wallpaper, even heavy ones.

Just recently, applying foam plastic (polystyrene foam) to the walls became a common technique for thermal insulation.

Even today, the material is frequently used for facades, ceilings, and other surfaces because of its low cost. However, it is not appropriate for the upholstery and has significant drawbacks:

• Wallpaper glued to foam easily subjected to mechanical acts and break off. This is due to the fact that the material does not have the necessary stiffness;
• To get the desired level of insulation, a layer of foam at least five centimeters with a thickness will be required. This design will not be aesthetically aesthetically excreted;
• When subsequent repair of the room, you will have to remove not only the wallpaper, but also the insulation itself. Without damage, it will not work to remove the finishing material;
• One of the important reasons why it is impossible to use polystyrene – flammability. According to the rules, when installing it should be isolated by another non -combustible layer.

How to choose a heater: tips

Considering the type of wallpaper and the state of the walls, the proper type of heat-insulating material must be selected in order for it to meet the specified requirements. Suggestions:

• roll-type insulation has additional functions: it levels the surface, has soundproofing and vapor barrier qualities, and wallpaper can be glued to it several times;
• when purchasing, read reviews about the manufacturer and the technical qualities of the product;
• consult with the seller before choosing, check the characteristics of the material;
• Cork insulation costs on average from 900 to 6 thousand rubles, while roll insulation costs around 900-1000 rubles per piece. Prices vary depending on the company.
