type de question: Insulation

The evaluation system Leadership in Energy and Environmental Design (LEED) promotes the construction of green buildings. For this accreditation, it is necessary to meet several criteria for the universal components, construction, type of roof, and energy savings. Please refer to the certification requirements: www.ecohabitation.com

The insulation needs vary depending on the building system and the type of roof. You are advised to consult the description sheet to know the R-value of the insulation. In general, the higher the R-value, the greater the insulation.

When the attic is poorly insulated, you notice the formation of ice on the roof and icicles around the edges. The cost of electricity is higher for air conditioning and for heating. In addition, the temperature seems difficult to control and sometimes causes discomfort inside your home.
