How to insulate the ceiling in a private house?

To minimize the loss of heat through the structure of the building, the question often arises as to better insulate the ceiling in a private house. Warm air under physical laws rises upward and touches the cold surface of the uninsulated ceiling. This can cause condensation and mold. Warming the ceiling can be minnow, foam, sawdust, expanded clay and other loose materials. Sometimes for this purpose even cuttings of a sintepon which are sewed up in special mats from a film material are used. Heaters do not allow air to escape outside, helping to keep it inside.

Ceiling insulation options

Consider how to properly insulate the ceiling in a private house with your own hands from the inside with the help of mineral wool. To do this, you will need:

• minivat;
• beams;
• self-tapping screws and drill;
• knife;
• a stapler;
• vapor barrier film and acrylic tape.

Insulate the ceiling in the house

1. The heater fits into the interstitial space. In this case, the width of the layer should be 15 mm larger than the distance between the rails. Plates of mineral wool can be cut to the desired size with a knife.
2. When laying the second layer of insulation it is recommended to observe the flaring of the joints of the plates by half their length. Cross the rafters sewn additional lath from the bar. Another layer of insulation will protect against the accumulation of cold on the lag.
3. Further, the mineral wool is protected by a vapor barrier film, which will protect it from the penetration of steam from inside the room. It is rolled out and fastened with a construction stapler. The film webs are lapped and glued together with acrylic tape.
4. Next, you can lay the foundation for the finish of the ceiling, for example, OSB sheets.

The ceiling can be insulated both from the inside, and from the attic or street side, if it is an attic floor. Outside, almost any type of insulation can come. Interior decoration requires the use of finishing materials, so this method is more expensive in terms of implementation. Warming of the attic space is a less expensive method. For example, the space between the lags can be covered with sawdust or expanded clay, previously nailing the vapor barrier film. But each kind of material has its own characteristics. For example, sawdust is fire hazardous.

Warming outside

As an inexpensive option, it is possible to insulate the ceiling of a private house from the outside of the attic with the help of a foam plastic. It gives waterproofness and noise absorption, easy to install and does not create an additional load on the overlapping, retains its shape for a long time, does not rot. To do this, you need:

• Styrofoam;
• hydrobarrier in the form of a film;
• mounting foam;
• stationery knife.

Let's get to work:

1. First comes a layer of waterproofing, in this case a vapor barrier film is used. It is nailed outside on the boards and logs.
2. Styrofoam slabs are laid out between the lags. You need to put it with minimal clearance. If necessary, he is clipped with a clerical knife.
3. The insulation is laid in two layers.
4. Seams between the slabs of the material are blown with construction foam to improve sealing. Sealing joints improves the insulation of the house.
5. Plates of polystyrene foam are leveled to provide a finishing finish, if necessary.
6. In this example, the top can be covered with a board.

Good thermal insulation and the correct choice of insulation can reduce the cost of heating in the cold season several times. A qualitatively insulated ceiling reliably protects the house from the cold and provides additional noise insulation.
