If you want to insulate your house indoors and outdoors, you will need to choose the appropriate insulating materials as well as the type of insulation you want, cladding or double walls for the exterior or with a metal frame or blade. air for the interior.
How to insulate your house indoors?
In order to insulate your home indoors, several steps are important before choosing what type of insulation you want.
Establish a diagnosis of your home
Before insulating your house, you must take an inventory and check for any weaknesses in terms of insulation. First of all, it is necessary to assess the air circulation in the space by the ventilation system.
If this air circulation system proves to be defective, insulating such a space could contribute to the accumulation of stale air and increase the humidity in the room.
In addition, the humidity level in your house must be measured by a professional and the insulation work can only begin after remediation work on your walls if they turn out to be permeable.
Furthermore, it is important in the diagnosis to identify the thermal bridges in your house, i.e. the precise places where the insulating barrier is broken, which causes a variation in thermal resistance. This in addition to air infiltration must be taken into account in order to insulate your home as effectively as possible.
Advice
Carrying out an energy audit allows you to establish a complete diagnosis of the house. Contact a professional before embarking on insulation work.
Choose what type of insulation you want for your interior walls
In order to insulate your house indoors, several wall insulation techniques exist.
Different wall insulation techniques are possible:
- Insulation under a metal frame in the event of a defect in your wall because it will be supported by a frame in which the insulation will be fixed;
- Insulation by glued lining allows the insulation to be fixed to a plasterboard and thus stuck to the wall with an adhesive mortar;
- Air gap insulation in the case of porous walls since a wall approximately 2 cm from the wall will be installed, the insulation will be placed in the space created;
- Insulation on the other hand masonry partitions when your wall is deficient because a new wall will be erected in parallel and between the two walls, the insulation will be placed via panels;
- Projected insulation to directly cover your interior wall with insulation;
- Insulation by direct application of insulating panels or blocks against the wall.
How to insulate your house from the outside?
In addition, if you want to insulate your house from the outside, several techniques also exist.
Insulation with cladding
In the case of insulation with cladding, an external frame is placed against the wall to support the insulation and protect it from climatic hazards.
Insulation with coating
This type of exterior insulation allows the insulation to be fixed with dowels or glued with adhesive mortar directly to the facade of the house. The insulation is then covered with a bonding coating, then a base coat and finally a finishing coating.
Insulation thanks to double-walled masonry walls
In this type of exterior insulation, an exterior wall and an interior wall are constructed. Between them, the insulation is placed. The exterior wall then serves as a facing.
Can you insulate a house both indoors and outdoors?
Why insulate your house indoors and outdoors?
Considering insulating your home inside and out is interesting because it allows you to improve the energy performance of your home and thus save energy.
In fact, good insulation can allow you to reduce your energy costs by 25%. In addition, you will be able to improve your thermal and acoustic comfort.
Insulating indoors is cheaper and easier to install, although it may encroach on your living space. Outdoor insulation will require more complex implementation which will affect your entire building but will offer you more efficient insulation.
What are the constraints before insulating your house inside and out?
First of all, know that it is essential when you want to insulate your house inside and outside, to ensure that the insulation outside is twice as much as that placed inside.
Indeed, it is important to ensure that your double insulation does not prevent the walls from breathing, which would cause humidity to accumulate inside your house.
Advice
For an interior and exterior insulation project, the insulation on the exterior must be twice as much as that placed on the interior.
Which insulating materials should you choose to insulate your home?
The choice of your insulation is essential and varies depending on whether you are insulating indoors or outdoors.
For indoor insulation, the following materials are the most efficient:
- Cellulose wadding
- Wood wool
- Recycled cotton
For outdoor insulation, the following materials are the most effective:
- Aerated concrete
- Hemp brick
- Rigid wood fiber
FAQs – insulate a house indoors and outdoors
What are the materials commonly used for interior insulation of a house?
The materials commonly used for interior insulation include glass fiber, rock fiber, cellulose foam, polyurethane foam, and polystyrene panels. The choice depends on various factors, such as the area to be isolated and the budget.
Comment then-how effectively insulates the interior walls of my house?
To insulate interior walls, you can install panel insulators or apply the insulator in bulk. Be sure to treat the thermal points and choose a material suitable for your needs. The installation must be carried out in accordance with local construction standards.
