How to insulate the ceiling of the house from the attic

I’m building a country house and work is now stuck at the stage of thermal insulation. Therefore, in fact, I want to ask the experts of your site about what modern materials are used to insulate the ceiling from the attic. Tell us about inexpensive heaters, and, most importantly, about those that you can easily handle on your own.

Answer

The fact that you are asking a question in this vein is very correct - the well-known folk wisdom “Do you want to do something well, do it yourself” also says. We will try to help you.

To begin with, you have correctly chosen the method of insulation - from the attic. This will save the design of the insulating cake from freezing, increase its service life and will not steal a single centimeter of the height of the premises.

Ecowool is considered one of the best and safest material for insulation. It has excellent thermal insulation, and its installation technology eliminates any "cold bridges." Mineral wool, which includes basalt fiber boards, glass wool, stone wool and other fibrous materials, also copes well with warming. Although their thermal insulation ability is not far from ecowool, all these heaters have one significant drawback - they are afraid of moisture and, when wet, lose most of their properties. Although the attic is a relatively dry room, when using mineral wool, you will definitely need to install waterproofing and a vapor barrier membrane.

But such a modern material as extruded (extruded) EPSPS polystyrene does not need additional moisture protection and has not only good hydrophobic properties, but also minimal thermal conductivity. The disadvantage of EPS is that this insulation is a rigid plate and therefore, when laying it, it will not be possible to avoid the appearance of cold bridges in the place of passage of the beams.

With the installation of all the materials reviewed, you can easily manage it alone or with an assistant. And if you decide to still turn to specialists, then consider another option - insulation with foamed polyurethane (gas-filled plastic).
