Comfortable living conditions in a private house are created not only due to competently erected building structures that take into account the climate zone. A special role is played by modern heaters. The cheapest or quite expensive materials do not allow the room to cool in the winter, which leads to energy savings and, consequently, to reduce financial costs for house maintenance. In a hot summer, the function of the insulation is to prevent overheating of the internal walls and maintain the optimum temperature inside the living rooms.
Masters Tips
Specialists in the field of masonry recommend increasing the thickness of the walls and purchasing the cheapest insulation for the house . Finishers are advised to choose the best value for money for each family.
A competent approach to project development, construction and home decoration will help to understand the variety of goods, which will force the developer to turn to professionals and pay for their services.
A budget construction option is also possible. It is only necessary to thoroughly study the information available on the Internet on this issue.
Masters with great experience talk about the need to select material according to the following criteria:
- wear resistance;
- water tightness;
- fire resistance;
- environmental friendliness;
- resistance to mold or mildew;
- low coefficient of thermal insulation;
- release form;
- ease of installation.
Types of materials
To save on construction, choose the suitable and possibly the cheapest insulation, the owner of the house needs to classify the samples on the market. There are heaters:
- by location: for exterior and interior decoration;
- composition: mineral, basalt, polystyrene, from extruded polystyrene foam, from liquid penoizol;
- at the place of application: for floor, walls, ceiling, roof, basement.
Indoor and outdoor insulation
The cheapest insulation for the walls of a frame house is any material chosen for interior work. Even giving preference to an elite manufacturer, you can save money by fixing the material on the walls yourself. In addition, a heater shaped in the form of sheets or rolls will allow you to level the surface without additional costs. The minus of internal work is the reduction in living space. Unsuccessfully selected for the walls, the cheapest insulation can cause their subsequent blackening and the formation of condensation and mold foci.
Among construction experts, there is an opinion that external thermal insulation is economically disadvantageous, since it requires the involvement of specialists and additional equipment.
At the same time, counting on the long term, it is possible to justify the use of street insulation, especially when using the wet method. An excellent result of outdoor work is:
- lack of condensate;
- high efficiency of thermal insulation;
- acceptable finish appearance.
Structure
Mineral compounds are among the cheapest heaters of a wide range of applications. They are made of fiberglass and are used for walls, floors, roofs and flat roofs. The advantage is excellent thermal insulation properties, the disadvantage is the release of formaldehyde when heated.
Basalt insulation has a high density, safety and fire resistance. The cost of 1 square meter often exceeds the mineral sample twice. Specialists recommend this material for roof trimming.
Polyfoam is produced in sheets, due to which it is considered the easiest and most convenient for installation. An affordable price and versatility put it on a par with mineral insulation. In addition, it does not require special costs for finishing. A layer of plaster and regular painting is enough. The minus of polystyrene is the generation of caustic smoke during a fire, which rarely stops buyers trying to save on construction work and materials.
Extruded polystyrene foam is the same polystyrene that has undergone special processing and obtained a more uniform structure. Thus, the sample receives lower thermal conductivity and vapor permeability. The material is not subject to deformation and does not change the technical characteristics due to temperature differences. Distinctive features are also ease of installation and low weight of the constructed structure.
Liquid penoizol is used pointwise to close cracks and gaps. The sample, along with mineral compounds, is considered to be the cheapest insulation, but it is not recommended to use for finishing an entire wall or any other internal surface.
Heater for different designs
The cheapest insulation for the walls of the house is considered to be foam. Basalt cotton wool will cost a little more. If the owner does not intend to save on insulation, then builders recommend spraying with polyurethane foam, which will significantly increase the service life of the finish.
For the floor, it is better to choose extruded polystyrene foam, especially for insulation of a concrete coating. The ceilings and floors are laid out with mineral wool.
For roofing, it is recommended to use basalt compounds in sheets, and for the attic - bulk materials such as expanded clay or a mixture of sawdust and hydrated lime.
It is preferable to finish the foundation with polystyrene foam, the base with polystyrene, and for the basement, insulation work should be carried out only after the formation of the drainage layer.
How to choose the right insulation?
The main rule in the selection of insulation is the orientation on the material of the surfaces that are to be finished. Not the least role is played by the installation site and the climate zone. Nevertheless, a universal insulation in all respects does not exist. It is also necessary to be based on the opinions of professionals and their financial capabilities.
For wooden houses, fiberglass or stone wool is suitable, for brick buildings it is better to choose mineral insulation. Concrete walls require insulation from the outside with siding or curtain panels, inside with expanded polystyrene or mineral wool under drywall.
Experts recommend the selection of the cheapest insulation for a frame house by means of heat engineering calculations that take into account the region, climatic conditions, building structure, characteristics and composition of the finishing material.
Domestic manufacturers
Among Russian brands, the Technonikol company, which produces reliable and high-quality building materials, has gained particular popularity.
The range of thermal insulation materials includes about twenty items, from the cheapest heat insulation materials for floors based on stone wool or extruded polystyrene foam to expensive PIR thermal insulation boards. Plates are available in several types with an individual purpose for:
- sexes;
- walls;
- baths;
- a balcony;
- with foil lining;
- with an additional layer of fiberglass.
The manufacturer positions the product as the best achievement of the company, which has continuous advantages:
- Minimum thickness, not concealing living space.
- Environmental friendliness and safety.
- Convenience of installation without the use of special skills.
- Low thermal conductivity.
- Minimum water absorption of the material.
Brand from Finland
Paroc is a leader in building insulation materials with manufacturing facilities in Russia, Poland, Lithuania, Finland and Sweden.
The company guarantees the quality of goods, high energy-saving indicators from the use of products and produces heaters for:
- walls;
- flat roofs;
- sexes;
- stucco facades;
- sandwich panels.
In addition, the company produces general construction insulation, able to work as the cheapest insulation for roofs and walls, and to carry out the main function on a par with the analogues of world famous brands.
Originally from Germany
Today, the non-existent company Pfleiderer can hardly be called a German manufacturer. Despite the fact that the company was originally from Germany, in 2002 it was acquired by the Spanish concern URALITA.
The merger of the two divisions gave rise to the new URSA brand, producing materials in the categories:
- mineral insulation based on fiberglass GEO;
- heaters for professional use TERRA;
- vip insulation material PUREONE;
- XPS polystyrene insulation;
- steam, hydro and wind insulation SECO.
Builders reviews
Any specialist prefers to work with quality material. However, the production of insulation is not a technically difficult process, and marriage, as such, is practically absent. In this case, the responsibility for the purchase of insulation lies entirely with the construction customer. The recommendations of professionals are limited to the name of the material, but in no way affect the choice of the manufacturer.
Reviews of inexpensive domestic heat-insulating materials are often no worse than the opinion of builders and ordinary people about the expensive products of famous brands. Therefore, experts recommend choosing a heater, based on the material of the house being built and the financial capabilities of the owner of the building.
