Poor heat insulation of the ceiling provides a high level of heat loss. Heat heating devices is quickly displayed into the attic, which does not improve living conditions in the house. In this case, the ceiling of the house should be insulated. Work on internal and external insulation of the ceiling can be done independently.
First of all, you should study the state of the overlap. Is it able to withstand additional loads. It is also necessary to choose the insulation for the ceiling. The material should be light, fireproof, resistant to moisture (evaporation) and not accumulate it. Otherwise the processes of mold and various fungi are activated. In addition, especially for internal work, the insulation for the ceiling should be environmentally friendly.
For outdoor insulation of the ceiling of the house (flooring of the attic), you can use rolled, bulk or solid heaters. You can pour the surface with a mixture of concrete with expanded clay or sawdust (if the state of the ceiling allows). A layer of sawdust, expanded clay, bulk synthetic insulation or mineralvates will also improve the characteristics of thermal insulation. To seal the cracks and seams, you can use the installation foam. External insulation of the ceiling of the house does not require external attractiveness, it is desirable that the resulting surface is flat, convenient for further use. In the case of using sawdust, it is required to take into account the heating of the pipe during the heating season.
For insulation of the ceiling from the inside, it is better to use mineralvaty stoves. It is possible to warm the ceilings and with the help of organic plates, but they are fire hazardous and over time accumulate moisture. The use of polystyrene is also undesirable, so when heated, it emits phenol. Some materials (glass wool) irritate the skin during installation.
When choosing the material, the installation method should also be taken into account. You can fix the insulation with glue, but given the possibility of replacing or dismantling, it is better to use screws or nails. A vapor barrier is attached to the insulation, and then the finishing – drywall, wood, etc.D. The design of the suspended ceiling will help hide the insulation of the ceilings, leaving the possibility of access to the isolation material to control its condition.
In addition, if the attic is resident at home, then the roof should be insulated.
