How to Insulate Walls From The Inside: To insulate the walls from the inside, you can stick insulation to the walls or fix it using a metal frame. We can also create a second partition with an air gap, to guarantee sound and thermal insulation.
The materials used include rock wool, cellulose wadding, insulating paint, or polystyrene. Many individuals choose interior wall insulation over exterior wall insulation. It will be appropriate to choose a method adapted to the accommodation and its specificities.
With the right materials and installation carried out according to the rules of the art, improvement in energy performance is achieved. Don’t miss the few lines that follow, to discover the best alternatives.
What method of interior insulation?
Insulation under the metal frame
Insulation under a metal frame consists of installing insulation in the form of rolls or panels. It will be held by metal parts duly attached to the existing partition. The installation steps are:
- Fix the metal frame
- Slip in the insulation you have chosen
- Install the facing plates
To be able to use this method you will need to have walls in good condition. They must be able to accommodate the metal structure, which is fixed using screws. [How to Insulate Walls From The Inside]
Insulation by glued lining
For those who have smooth walls the glued insulation technique can be interesting. This involves laying down the insulation and gluing it to the plasterboard. Fixing to the wall is done using an adhesive mortar.
The person responsible for the installation will then have to carry out work to create a watertight joint between each plasterboard.
Air gap insulation
Air gap insulation is particularly indicated if the walls are not able to accommodate one of the two previous solutions. This involves installing the insulation using a structure made of wooden battens.
It will be necessary to leave a space between the insulation and the wall of the dwelling. This air gap ensures ideal thermal and sound insulation.
What material should I choose to insulate the walls from the inside?
To insulate the walls from the inside, it will be possible to use mineral wool such as rock wool or glass wool. Their effectiveness in terms of sound and thermal insulation is no longer in doubt. There are also natural alternatives with wood fiber linen or even sheep wool.
It is important to emphasize that most of the time these types of insulation must be installed at a certain thickness, to reveal their full potential.
Faced with the challenges of interior insulation manufacturers have therefore innovated to offer solutions allowing the loss of as little living space as possible. First of all, there are certain synthetic materials such as expanded or extruded polystyrene which offer ideal performance.
It will also be possible to use aerogels or even insulating paint to increase the energy performance of a home. [How to Insulate Walls From The Inside]
Define your interior insulation project
It is important to define your expectations following the insulation of your home from the inside. If you want to benefit from thermal insulation there are many materials from synthetic insulation to mineral wool.
If you also want to have sound insulation to protect yourself from noise pollution certain methods and materials are unsuitable. If you have discovered the famous insulating paint in a DIY store know that it will be completely ineffective for sound insulation for example.
Furthermore, the installation method must be adapted. If possible, leaving an air gap between the wall and the insulation solution will allow noise to be optimally absorbed.
