Superstructure of the attic in the old reconstructed house
In order to build an attic above the house to begin with, it is necessary to make sure of the reliability of the structure, on which almost all the load of the superstructure will lie. If it is not strong enough, then it is necessary to install columns on the foundation. They will be the bearing structure for the constructed attic.
Please note that the structure on which the entire load of the superstructure is laid should not be damaged. If it is not, then its skeleton should be replaced with a more reliable one. In this case, part of the load on the attic will carry the walls.
The strapping belt is an integral part of these construction works. He distributes the load of the attic to the restored house, uniting their walls together.
This belt is made mainly of reinforced concrete, but claydite-concrete structures are also found.
For the construction of an attic above a multi-storey private house it is recommended to use a metal frame, it is more reliable. It is necessary that the overlap between the house and the attic was one-piece.
Load-bearing mansard construction in the private house
The attic and attic of the house are very similar in design. When erecting an overbuilt structure it is necessary to take into account all the weather conditions in the terrain in which the house is located. The superstructure must withstand the wind and pressure of the snow layer.
For the construction of the attic the best way is to use the most durable materials. These are metal, wood or galvanized profile. If desired, any combination of the above materials can be used.
It should be noted that wood is best used where there is no electricity, since welding in such structures is difficult. Before working with a tree, it must be antipirated. This fireproof wood, it is needed to ensure that this material is not flammable in extreme situations.
Various frames, columns and rafters are load-bearing structures. They are attached around the perimeter of the outer wall.
It is best to choose lightweight materials for the power structure, since they can be assembled with bolts and rivets without welding. These are wood or galvanized profile.

Heat insulation cake in the superstructure of the attic floor
When building an attic structure, it is necessary to take responsibility with responsibility for choosing the material that the superstructure is insulated with.
There is no heat cushion in the attic floor, therefore the room loses about 25% of the heat.
Heat insulation of the roofing cake
For the warmth of the roofing cake, it is best to use either expanded polystyrene or basalt insulation. It should be taken into account that it is risky to increase the superstructure of the lukewarm, since it is easily ignited.
In sloping roofs, it is best to use basalt slabs. They are laid tightly in several layers. If the insulation is not packed tightly enough, then over time they can deform, which will lead to cavity formation.

Steam insulation of roofing cake
It is recommended to use a special film for the vapor barrier of the roofing pie, due to which the vapors do not penetrate into the room, and at the same time it releases them from the insulation.
Ventilation of roofing cake
Because of the temperature difference in the superstructure, condensation forms. It can lead to the formation of mold and icicles, which is bad for the facade of the building. To protect the built-up floor from such formations, a roof space and a heater make a ventilation space.
