Warming houses of foam blocks traditional materials

What is the insulation of the house of foam blocks

How do you imagine a cozy home?Undoubtedly, as a place where it is easy to breathe, and, nevertheless, warm even in the most severe frosts.And how can you get the heat, except with the help of a reliable thermal insulation?Only now house warming of the foam blocks can be different.

As mentioned above, the insulation should be breathable, otherwise the rooms will always stuffy and need mechanical ventilation.This means additional power consumption or drafts, if ventilation provides a simple way - open windows.

Therefore, we begin meticulously chosen materials for wall coverings.Expanded polystyrene is not suitable, it is absolutely vapor proof, however, if you have a good ventilation system, why not use this reliable heater.

But mineral wool blends perfectly with concrete blocks for the simple reason that she is missing a couple, perfectly retains heat inside the house and does not create cold bridges for access from the outside.However, it should be borne in mind that an ordinary mortar can provide those same bridges.So, if you want to secure thermal insulation, use glue and masonry blocks, and the installation of insulation.

Warming house of aerated concrete - what is the complexity

Many experts do not hide the fact that manufacturers have considerably embellish the characteristics of aerated concrete, which is why those who use this material for the construction of town houses, often have problems with insulation.It seems to be done correctly, and the rooms in the winter cold.The fact is that the aerated concrete thermal conductivity is greatly underestimated, and if we start from a manufacturer's declaration insulating properties, the thickness of the wall must be within 380 millimeters.

However, in fact, taking into account the heat loss of the reinforcing belts, needed because of the fragility of the material in the construction of the second floor, as well as the thermal bridges in joints masonry thickness must be at least 640 millimeters.And it is in the best case, and in accordance with SNIP and did more than a meter.

These calculations, of course, does not take into account warming house of aerated concrete.However, even with 380 mm thermal insulation for walls is not enough, so insulation is best performed by an integrated circuit .Total number of such schemes, there are two: external and internal insulation, both of which are quite effective in isolation.But in the case of aerated concrete.

should also take into account what has been said, against foam blocks - namely, the use of "breathing" insulation such as mineral wool or fiberglass.As an internal heater in addition to the foam can be used mineral wool.

How to insulate foam blocks and aerated concrete?

Unfortunately, due to the porosity of the materials ordinary nails or screws for aerated concrete and similar building blocks are not suitable .How to fix insulation panels?Either use chemical anchors or cheaper Twist dowels.

There are other options, for example, just to put glue on the insulation, aerated concrete blocks and in fact should ideally be glued rather than attached cement solution with sand.In any case, insulation panels should be laid firmly as possible, without gaps, promazyvaya glue joints because any gap will become a loophole for the cold.

For aerated concrete produced special anchors and mechanical anchors that do not even require drilling, they simply hammered into the wall.

for interior decoration can be used Epps or otherwise extruded polystyrene.Yes, he is not breathing, but previously we did not recommend such materials due to lack of water vapor permeability.But there is such a thing as the dew point, which is expressed in different heaters in their own way.So, in extruded polystyrene dew point falls on the thickness of the thermal insulator, that is, hidden deep in its structure.

And given the normal room ventilation and relatively low humidity in it, you can not be afraid of condensation in the winter with sufficient wall thickness.Marc Bloch D500 thickness of half a meter you would be enough to protect themselves from winter frosts.
