Styrofoam

I have been engaged in facade insulation for more than 10 years and I can say that they have not yet come up with better materials for decorating the facade (except for minvata but it is more expensive), the foam is cheap and it is easy to work with. The main thing is to follow the right technology.

Cheap, lightweight, durable, low thermal conductivity, easy to process and finish, high speed

Burning, eating mice, pecking chickens)

Using the foam, they insulated the roof of the garage, which adjoins the house. As regards the heat-insulating properties, everything is fine - the garage has become noticeably warmer, and this is felt. The joints were covered with mounting foam so that cold air did not enter through the cracks. But the problem is that the foam began to gnaw at the mouse. In silence, it is very audible that they made moves inside the foam. Perhaps soon the holes will even be through. So, we will no longer use polystyrene to warm other rooms.

Good thermal insulation properties, low price, easy to install

Not suitable for private houses if they have mice.

Polyfoam is a good insulation. However, before applying it, it is worth considering what problems exist in your room. It is not recommended, for example, to use polystyrene in homes where there are problems with rodents, high humidity and inadequate ventilation. If the named moments are absent, you can safely warm the room with polystyrene foam.

This insulation is one of the cheapest, it is lightweight, has excellent insulation, moisture repellent properties, is easy to use (it will not be difficult to cover the walls with polystyrene foam even alone).
It is indispensable for wall insulation in city apartments, but for summer cottages it is not the best option.

Low price, lightness of material, repels moisture

Fragility, the need for additional ventilation

I used polystyrene as a heater during construction. It so happened that the second floor of the house could not be completed in one season. It was urgent to insulate all the walls and ceiling of the unfinished floor. For this, I used polystyrene 50 mm thick. Outside, around the perimeter, vertically screwed 50 x 50 bars, inserted foam sheets between them and covered everything with siding. The gaps were filled with mounting foam. Now February is coming, and we can say that warming works perfectly.

I used polystyrene because two years ago I just warmed the change house like that and until now there have been no complaints. I thought that was enough for the maximum season, but still everything is in order.

First of all, lightness. No helper needed. Secondly, the price. Thirdly, it is easy to dock, you can literally remove the excess with the cutter. And, as it turned out, foam insulation is quite durable.

The main drawback, it seems to me, is the fragility of foam sheets. You have to work very carefully. And yet it must be covered from direct sunlight, otherwise it will soon begin to crumble at any touch. But he has more advantages.

I thought seriously about polystyrene when I bought a corner apartment in a brick house from Soviet times, and the bedroom turned out to be a corner. In summer, nothing is in it, but in the first winter we froze thoroughly. Friends advised polystyrene, praised it for a long time, said that I would not regret it. He insulated the outer walls of the apartment 4 years ago. The wall in the winter is warm and dry from the inside, and in the summer it is comfortable in the room, so no air conditioning is needed. The temperature due to it does not rise in the house, but the existing one is kept, that's for sure. And this is a significant savings for your wallet if you have individual heating.

And even outwardly I did not notice any deformations of the foam. Everything is beautiful and without cracks for so many years. I recommend everyone this insulation, which passed my test. Yes, in addition, polystyrene is considered a relatively inexpensive and high-quality material.

Does not absorb moisture, durable, keeps temperature
