How to choose your roof insulation? Which insulation to choose for its insulation project? What are the
advantages and disadvantages of different roof insulation materials?  We present you with a detailed
comparison of the different types and materials of roof insulation so that you can choose the best roof
insulation for your project and your budget.

Which insulation solution to choose?
Before talking about the different insulators available on the market first, you need to have a little idea of ​​the project you want to set up. The insulation of a roof can be done from the inside and the outside. No solution is better or more advantageous than the other. On the other hand, each project has a solution best adapted according to the configuration of your roof and of course according to your need.

Evaluate the performance of an insulator
 2 indicators can be useful for measuring the performance of an insulator:
• Thermal conductivity: λ (lambda)
• Thermal resistance: R
The thermal conductivity lambda
The lambda thermal conductivity defines the ability of the material to conduct heat. The lower the thermal conductivity, the higher the performance of the insulation is. An insulator that does not conduct heat will stop it and prevent it from escaping through the roof. We should seek a lambda as low as possible to choose its insulation.

The coefficient of thermal resistance R
The coefficient of thermal resistance R defines the ability of a material to withstand cold and heat. The higher the R coefficient, the more the product is considered to be a good insulator.
