9 best home insulation

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

In a private house, in contrast to a multi-storey one, there is much more heat loss. The air heated from the heating gives off the temperature to the walls, windows, roof and floor. In order not to spend even more money on heating, it is advisable to carry out insulation, for which various materials are produced. We have prepared a rating of the best home insulation, based on feedback from masters and ordinary buyers, as well as product characteristics. This will help you navigate the available variety and choose insulation for your home with optimal properties for walls, attic or floor and at an affordable price.

How to choose insulation for your home

Our rating contains the most popular types of insulation. Before considering it, we will briefly touch on the main parameters that you should pay attention to when choosing:

  1. Thermal conductivity. The indicator informs about the amount of heat that can pass through different materials under the same conditions. The lower the value, the better the substance will protect the house from freezing and save money on heating. The best values ​​are 0.031 W / (mK), the average are 0.038-0.046 W / (mK).
  2. Water vapor permeability. It implies the ability to let moisture particles pass through (breathe) without holding it in the room. Otherwise, excess moisture will be absorbed into building materials and promote mold growth. Heaters are divided into vapor-permeable and impermeable. The value of the former ranges from 0.1 to 0.7 mg / (ppm Pa).
  3. Shrinkage. Over time, some heaters lose volume or shape under the influence of their own weight. This requires more frequent fixing points during installation (partitions, clamping strips) or use them only in a horizontal position (floor, ceiling).
  4. Mass and density. The insulation characteristics depend on the density. The value varies from 11 to 220 kg / m3. The higher it is, the better. But with an increase in the density of the insulation, its weight also increases, which must be taken into account when loading on building structures.
  5. Water absorption (hygroscopicity). If the insulation is directly exposed to water (accidental spillage on the floor, roof leakage), then it can either withstand it without harm, or deform and deteriorate. Some materials are not hygroscopic, while others absorb water from 0.095 to 1.7% of the mass in 24 hours.
  6. Operating temperature range. If the insulation is laid in the roof or directly behind the heating boiler, next to the fireplace in the walls, etc., then maintaining the elevated temperature while maintaining the properties of the material plays an important role. The value of some varies from -60 to +400 degrees, while others reach -180 … + 1000 degrees.
  7. Flammability. Heaters for the home can be non-flammable, low-flammable and highly flammable. This affects the protection of the building in the event of accidental fire or deliberate arson.
  8. Thickness. The cross section of the layer or roll insulation can be from 10 to 200 mm. This affects how much space is required in the structure for its placement.
  9. Durability. The service life of some heaters reaches 20 years, while others up to 50.
  10. Simplicity of styling. Soft insulation can be cut with a little extra and they will tightly fill a niche in the wall or floor. Solid insulation needs to be cut exactly to size so as not to leave 'cold bridges'.
  11. Environmental friendliness. Implies the ability to release vapors into a dwelling during operation. Most often these are binder resins (of natural origin), so most materials are environmentally friendly. But during installation, some species can create an abundant dust cloud that is harmful to the respiratory system, and prick hands, which will require protection with gloves.
  12. Chemical resistance. Determines whether it is possible to lay plaster on top of the insulation and paint the surface. Some species are completely resistant, others lose from 6 to 24% of their weight upon contact with alkalis or acidic environment.

TECHNICOL XPS TECHNOPLEX

In this category of heaters, in the first place is the product known for its white and green packaging. Home insulation is made in Russia. The material is produced in the form of plates with a thickness of 20 to 100 mm, which is liked by the masters in the reviews, since it allows you to choose the optimal section for various parts of the house. The use of thermal insulation in the bathroom and in the kitchen is allowed, because it is capable of transmitting steam with a coefficient of 0.01 mg / (mhPa). At the same time, the surface does not absorb water, preventing the development of fungus.

Our experts liked the insulation because of its compressive strength of 0.1 MPa at 10% deformation. This allows you to insulate the floors along the logs and not worry about the load placed on them. It can also be used when organizing underfloor heating in a house with pipes or cables. This effect was achieved by adding nanocarbon, visible by its light gray tint. For this product and pressed into the rating as the best for floor insulation.
