Preparing the building for the attic of the attic
Before proceeding to the construction of the attic above the residential or holiday home, it is necessary to take into account certain rules and sequence of actions.
The first step is to create a project.
For the correct design, it is necessary to take into account the load of walls and foundation, external design, etc. Designing is better placed on professionals, because they have all the necessary knowledge about the structure and application of various materials. In addition, the draft attic in most cases must be approved in the government, and the correct calculations of specialists in this matter will only be used for future use.
Next step by step we will consider the remaining items of the attic overbuilding.
Construction of the attic at the dacha
Step 1: dismantle the old roof
The next task for building the attic above the house is to dismantle the old roofing material. This will strengthen the structure and save money for repairs, as well as make the construction more secure.
You can remove old shelter from home with your own hands, but some actions should be entrusted to a professional, as this can be dangerous for a person who does not understand the technological component of the work, i.е.not a specialist. The tool for dismantling the roof is a nail, which helps to remove slate and ceramic tiles. To remove the metal, you need two people and special equipment.
The entire process of dismantling is divided into the following stages:
- Dismantling of waterproofing and thermal insulation
- Removing the planking
- Removing the crate
- Removing the fastening structure( rafters)
Step 2: strengthening the walls of the floor
When constructing the attic, it is necessary to take into account the load not only on the foundation of the house, but also on itswalls. More seriously, it is necessary to treat the load distribution on the walls of the adjacent floor. They need to be carefully strengthened.
The first thing you need to do is calculate the strength of the walls according to their dilapidation and degree of exploitation. In general, this process is divided into several actions that are best performed by a specialist.
In the photo below you can see the scheme on which the layers of the roofing of the house are placed.
Step 3: Insulate and waterproof the ceiling
In order to prevent the influence of humid and warm air currents on the space and surfaces of the attic, the mansard should be covered with various waterproofing and thermal insulation materials. The main consequences of the absence of these materials are: high humidity, unhealthy temperature conditions, rotting and warping of surfaces, etc. The listed things can change your health and mood for the better.
For performance of these works you can use any waterproofing material that is acceptable for you. Mandatory consultation is required.
This material can be a perforated film, a polymer-membrane film, hydrophilic rubber, coating waterproofing, penetrating parts and sprayed insulation. And recently, polymer-bituminous compounds began to acquire special popularity.
Step 3: create the walls for the attic
It is understood that the walls should be built only according to the project of the house, which was approved by the state body. Therefore, all directions, divisions and sizes must be observed. With any deviation, large disruptions to the integrity of the house and a decrease in the life of the housing are possible.
Only non-toxic materials are used for work, in particular, drywall. The process itself is very simple, and any person can cope with it.
How to finish the walls in the attic with plasterboard, look at the video in the next tab.
Step 5: build the roof for the attic
The roof must be insulated as much as possible to maintain the microclimate, but especially important is the internal insulation, which can be easily carried out. Using the following materials:
- Plasterboard or plywood to make a simple finishing layer
- Waterproofing foil to provide a vapor barrier
- Mineral cotton wool lay heat insulation
- Water tap that will provide waterproofing
- External roofing layer to be made of a reliable metal tile
It is recommended to connect experienced specialists for this kind of robot, and alsopay great attention to compliance with safety regulations.
More information about the specifics of the roof frame and mansard walls can be found in the video in the next tab.
Ventilation system for the attic
The required level of lighting and airtightness for the attic are provided by special windows. Their specificity provides for a stronger impact of atmospheric precipitation and the constant need for ventilation.
For the influx of fresh air, such windows are quite suitable, since they, mainly, have a swing-flap, which allows you to put the window in the mode of ventilation. This method is called the natural supply of air to the room.
In turn, forced ventilation should also not be overshadowed by installing auxiliaries and air inlets in the attic room. It can also be a door in the attic, the gaps between the door and the stairs. A deducing stagnant air in a room without windows can only be through a hood in the wall or ceiling.
Finishing and equipping the attic
This step involves the internal transformation of the room, the installation of heating. In addition, all the design ideas are embodied.
For high-quality and safe heating of attics, install special heating systems, for example, "warm floor", which will allow to use the attic space without problems for many years and guarantee reliability and safety.
