Insulating ceilings or walls in a garage, basement or living room is a very important step in building a home. Fortunately, it is also possible to insulate an old building to prevent heat loss and overconsumption of heating. There are different types of insulators on the market that all have advantages and adapt to very different situations.
Why choose to isolate?
The simple act of isolating the walls or ceilings of your home allows you to significantly reduce heat loss in winter, you avoid overconsumption of heating and help you reduce your electricity bill. Isolating your home is also an ecological act because by reducing your energy consumption, you reduce the emission of greenhouse gases at the same time. A good insulator retains heat in winter and conversely, prevents it from coming back in summer. It is also very popular because it reduces noise and offers a very pleasant acoustic comfort.
How to isolate ceilings?
To isolate a ceiling, you have the choice between different options. The first is to install a false ceiling and add insulation. For this kind of configuration, the ideal is to choose a roll insulation that will simply unroll above the false ceiling.
You also have the opportunity to put a metal structure over which you will screw or install the insulation in the form of panels. Once the insulation is laid, you can then install plasterboard to camouflage everything and optimize insulation.
The different types of insulation
There are different types of insulation on the market. They all have their own advantages and uses. The most common is expanded polystyrene. It is very appreciated for its lightness, its resistance and its very cheap price. Sold in panels or loose, it adapts to all situations. Glass wool or rockwool are also very common and are very easy to handle and install because they are in the form of a roll. There are other insulators such as cellulose or perlite very appreciated for their ecological side and their fire-fighting virtues, anti-insect and anti-mold.
In terms of price, polystyrene remains the cheapest at 5 euros per square meter while high performance polyurethane approaches 50 euros per m².
