Insulation for balcony

The market is full of modern building materials. How to choose the best insulation for the balcony without making an error that will spoil the results of expensive repairs? We give here a list of popular heaters, with a description of their main characteristics.

Which insulation is better for the balcony?

  1. Penofol . This material is supplied in rolls. Depending on the type, the foil can be on one side, on both sides, or on one side the foil, and on the second - an adhesive. In a very cold zone, it is better to use penoplex as the first layer, and penofol as the second layer. When stacking this insulation for the balcony is very convenient.
  2. Penoplex . This material is very often used in the form of insulation for the floor and walls on the balcony. The coefficient of thermal conductivity at it at height (0.03 W / (m * K)). Very small percentage of water absorption. 3 cm of penopolix replaces 10 cm layer of foam. In work, it is almost ideal, moderately hard, can be easily cut and does not crumble.
  3. Polyurethane foam . The technology of seamless insulation by spraying polyurethane foam has a number of great advantages, but requires a special installation. The coefficient of thermal conductivity of this substance is very high, in practice it is the leader among such materials. In addition, you fill all the microcracks and pores that are not even visible to the eye. This insulation for the walls of the balcony becomes one with the rest of the surface.
  4. Polyfoam . Among the advantages of polystyrene in the first place - the most affordable price. Serves this insulation for the balcony inside to 50 years, and to work with it simply. The thermal conductivity of this substance is normal (up to 0.044 W / (m * K)). Although the foam plastic is flammable, its ignition temperature is quite high - 491 °. A small flaw that interferes with the work - this material crumbles.
  5. Mineral wool . In the question of choosing a heater for a balcony, one can not ignore such popular material as mineral wool. It happens in the form of plates or in rolls. The thermal conductivity here is within (0.045-0.07), and the moisture absorption is about 0.5%. Advantages of mineral wool are a non-combustible substance that can provide excellent sound insulation. Suitable for structures where the insulation material does not carry loads. For the price, it is in the middle of the list.

Mineral wool is thick and requires the installation of a crate, but it does not burn and is an excellent sound insulator. Polyfoam is cheap, but inferior to the rest of the parameters penoplex. With foam it's difficult to work, it requires skills and a special tool, although it has excellent characteristics. Often it is necessary to combine several materials for a better effect. Therefore, the best insulation for the balcony should be chosen based on your budget, the size of the balcony space, and also guided by the maximum result you want to achieve repair work.
