In order to ensure a favorable microclimate inside a private house, cottage or additional buildings (for example, baths), as well as save on heating (this is especially true for a suburban building), insulation of the floor and walls is not enough. Therefore, many owners of private houses and cottages are wondering how to insulate the ceiling.
What material is better to use
It is best to choose environmentally friendly and non-flammable materials. So, professionals recommend insulating the ceiling with expanded clay, slag, clay with sawdust or mineral wool (in the form of plates or rolls). The latter option is not only inexpensive, but also most suitable for these purposes.
Mineral wool is characterized by ease of installation, fire safety and a high degree of thermal insulation. Before warming the ceiling with this material, it is necessary to create a vapor and waterproofing frame to protect the insulating layer from moisture and prevent its decay. The most suitable material for this is glassine.
You need to cut the waterproofing material with small allowances for a tight fit to the ceiling beams. After the vapor barrier layer is fixed, polystyrene (polystyrene foam) is placed on top.
Foam slabs are cut and installed in the same way as glazed windows, and small gaps between them are sealed with mounting foam. Then, on a layer of this material, one more layer of glassine should be laid. Such measures help to slightly increase the life of the insulation, eliminating the need for frequent overhaul of the ceiling coating.
How to insulate the ceiling. Process description
After creating a waterproofing frame, a thermal insulation layer is laid. For a greater effect, mineral wool must be laid in two layers according to the principle of brickwork. In other words, the upper layers of the insulation should cover the joints of the lower layers. Then you can start laying wooden boards on top of mineral wool. They provide solidity and integrity of the insulation layer, pressing against all previously laid materials.
How to insulate the ceiling in the bath
The main conditions in this case are the preservation of heat in the steam room and the prevention of condensation inside such a room. This, in fact, is the main difference between the insulation of the ceiling of the bath, since when performing such work in a country house, it is necessary that the air circulates more or less freely.
In addition, you need to make sure that moisture does not get into the attic. The ceiling of fiberboard, plywood or plastic for the bath is not recommended. Since condensation accumulates on the plastic, and fiberboard and plywood are deformed when wet.
Before insulating the ceiling of the bath, a layer of vapor barrier material is first laid . It can be building polyethylene, thick cardboard or aluminum foil. Roofing material, roofing material and glassine are not suitable for a bath - at high temperatures, these materials emit harmful substances and an unpleasant odor.
The installation of the ceiling in the bathhouse without an attic requires, in addition to vapor barrier, the presence of insulation (mineral wool, glass wool or perlite) and rolling lining. The structural elements here are beam beam and hemmed ceiling boards. If there is an attic, then a thin (1.5-2 cm.) Layer of clay coating is applied over the ceiling boards.
How to insulate the ceiling in the bath in this case? For thermal insulation, wood chips soaked in cement mortar are covered with a 15-17 cm layer. If this thickness is not enough and condensation appears on the ceiling, the backfill layer needs to be increased.
Roll-up panels, to which the ceiling is attached from below, must rest on the bars that are nailed to the side faces of the ceiling beams. The latter should be hermetically sealed in the brick wall, so that the warm air from the inside does not come into contact with the cold seal from the outside during the heating period, otherwise condensation will form, which will lead to decay of the tree.
So, warming the ceiling in a country house or in a bath is a task that can be completely solved even by the usual forces of one pair of skilled workers. However, it is better to entrust her decision to specialists. This will save time and effort.
