Feature: ceiling insulation

Save on heating costs and protect your room from outside noise by insulating your ceiling. There is a large choice in terms of insulating materials. What is the most suitable insulation for your situation? Follow the guide !

Why insulate your ceiling?

Insulating the ceiling aims to fulfill two very distinct objectives. Insulating a ceiling means reducing the heat loss from your home. A good way to save energy and reduce the amount of your bills! Insulating the ceiling is useful, regardless of the time of year. In winter, it retains heat inside and helps maintain a constant temperature. In summer, it prevents heat from entering your home. The ambient air remains fresh and pleasant. Insulating a ceiling also helps reduce the perception of outside noise. The insulating material improves acoustic comfort. You will appreciate if you live in an apartment building and have fairly noisy neighbors. Different types of materials can be used to insulate a ceiling. They can be classified into three categories: synthetic insulation, mineral and vegetable fibers, other renewable materials. Discover the properties of each of them.

The different insulation materials

Synthetic insulation is made from crude oil. There are three types: expanded or extruded polystyrene and polyurethane. Lightweight and resistant, expanded polystyrene is the most common. It is available in bulk or in the form of panels. The extruded polystyrene is more dense. Therefore, it has a higher insulating power. Its thermal conductivity is around 0.025 W / m.K. This type of insulation is only sold in the form of panels. Polyurethane dethrones the other two in terms of its insulating power with a thermal conductivity ranging from 0.022 W / m.K to 0.028 W / m.K. Among the mineral and vegetable fiber insulators, glass wool is the most widespread. Flax and wood fibers, other plant insulators, are still not very available on the market. Other renewable materials serve perfectly as insulation. Among these, cellulose. Available in panels or in bulk, it is fire-resistant, anti-insect and anti-mold. For maximum thermal and sound insulation, opt for cork. The latter is available in panels. Finally, perlite, an ecological insulator made from crushed rocks, is inert, non-flammable and rot-proof.

Which insulation to choose for your ceiling?

The choice of insulation depends on many criteria. Ask yourself the right questions before choosing your insulation. Here are some parameters that can help you make a wise choice. Ask yourself about the expected thermal performance. The thermal performance is indicated by the coefficient of conductivity. The thermal phase shift is one of the other criteria. Thanks to it, day and night temperatures tend to be equalized, a quality much appreciated in summer. Also ask yourself about the humidity level of the room to be insulated in order to choose a material with good performance in terms of humidity control. These insulators absorb the water vapor to restore it later, when the ambient air has become drier again. Do you have noisy neighbors? Some insulators offer good sound protection and others do not. Depending on the room, you will prefer an insulation resistant to humidity, settling or rodents. Choosing an insulator is not easy. Take the time to properly analyze all the parameters.
