As a result, cork insulation panels significantly improve your comfort inside your home.
Do you want to insulate your home and you hesitate because of the variety of materials available? Here’s everything you need to know about cork insulation boards to support you in the realization of your project.
The characteristics of cork insulation panels
The cork is a material present in the form of tree bark (cork oak) in nature, its extraction follows a rigorous and nature-friendly procedure to avoid rapidly deteriorating the trees. In France, cork is mainly used in the form of expanded cork panelsmost of it is used to make corks for wine bottles.
The particularity of expanded cork is that it can double in size by only being heated to 300°C.
This feature provides cork insulation boards excellent thermal resistance with a coefficient of resistance which oscillates between 7 and 8, especially since cork is very resistant to fires unlike wood fiber and the other most used natural insulators.
let’s remember that the average lifespan cork insulation boards is 50 years old, which is more than enough to cover your needs for a long time. As a result, cork insulation panels are very efficient and offer sound and thermal resistance perfectly suited to all homes, regardless of the region in which you live, in a recently built or old house.
The benefits of cork insulation boards
Know that cork has been used by man for several centuries and continues to be so successful, its efficiency and strong endurance have made it one of man’s allies in the field of construction, the oldest traces even date back to antiquity. This fervor carried by the cork man can be explained by the various advantages it offers, in particular:
- Great ease of use: cork is indeed very light, which makes it very easy to lay on different surfaces;
- Uncommon versatility: cork can be used in its natural form, transformed into panels or granules for the insulation of walls, lost roof spaces, or even floors;
- High thermal resistance: in winter, cork acts as a shield against outside air, while allowing air to circulate freely for interior ventilation in summer.
It is important to specify that the cork panels are more expensive than synthetic insulations, but they offer much more interesting performances than those of the latter. The impact on your energy bill is considerable.
Cork panels and sound insulation
Due to the density of these cells and their ability to double their volumecork panels are excellent sound insulators. Cork absorbs sound waves and blocks their transmission in space to prevent you from disturbing your neighbors, especially since these panels, often made of compact cork, are even used for the insulation of music recording studios.
Cork can therefore be perfectly used to soundproof adjoining walls, correct acoustic faults and acoustically insulate ceilings and walls to avoid the resonance of medium and high-pitched sounds between the different rooms of the house.
