How to insulate a house? The methods of insulation from the outside and from the inside are somewhat different from each other, so let's look at each view separately.
How to insulate a house outside?
External insulation provides a huge selection of products, which can be from basalt mineral fiber, from long-used glass wool, as well as from polystyrene (polystyrene). Before you decide on the choice of insulation, it is necessary to conduct at least a superficial familiarization with the main properties of these insulation materials in order to understand the possible minuses and pluses. Moreover, different types of insulation have different prices.
How to insulate a house with polystyrene foam? Polystyrene has a huge advantage - it can be easily glued to any surface, and it is also free from the drawback of most heaters - it does not fall off. Operation is not afraid of him, he is not subject to decay, and is not afraid of moisture. In addition, it is not sensitive to chemical effects. The only thing the foam is afraid of is acetone and gasoline. If it gets into the fire, it emits caustic smoke and smolders, so the slopes of windows and doors must be insulated with rollers rolled from basalt mineral wool. But the prices for it are the cheapest.
It is also necessary to know that the foam has a shelf life of seven years, after which it will begin to acquire heat transfer properties, which will affect the insulation of the house as a whole. In addition, under the influence of ultraviolet radiation, it begins to collapse irreversibly.
So, choosing a foam insulation, you save, on the one hand, and doom yourself to a new insulation in the next 10 years.
How to insulate a house with basalt mineral wool? There are several types of cotton products - slabs, mats, cotton wool, rolls, as well as fiber. Each product has varieties - with aluminum foil, with a synthetic bonding layer or with firmware made from calcined wire.
To conduct insulation with basalt mineral wool, it is necessary to perform a crate of wooden beams or aluminum profiles.
This is the most expensive type of insulation. But then it will serve you for many years, as it is not subject to decay and damage.
Fiberglass products are made on the basis of calcium carbonate. Glass filaments are obtained from it, which then break up into fibers. To warm the house from the outside with such a heater, it is also necessary to conduct a crate.
The price of fiberglass is intermediate, that is, more expensive than polystyrene, but cheaper than basalt wool. This type of insulation is as reliable and durable as basalt cotton wool, so it is better to opt for it than for foam.
There is another way to conduct cheap insulation of the house outside - vermiculite, which is a refractory heat-insulating material. Relatively light weight, environmentally friendly material of natural origin - all these are its advantages. This mineral is also used as bulk insulation; in addition, it can be added to the plaster mix and even concrete. At the same time, both thermal insulation and sound insulation are achieved.
Its cost is almost the same as that of polystyrene, but its reliability and service life are slightly higher.
How to insulate the house from the inside?
In principle, the same materials can be used as for external insulation. The difference is that the thickness of the insulation for internal insulation can be slightly less. In addition, the fact that the insulation of the walls somewhat reduces the space of the room plays a role.
The most important thing when carrying out insulation is to remember that it must be done honestly, without leaving gaps between the selected insulation, because in this situation there will be no sense in insulation.
You should not save on the quality of the material, it is better to use the brands of manufacturers tested by time, which are already able to guarantee the quality of their products.
And it is better to entrust the conduct of insulation to specialists who can perform it in a high-quality manner.
