Proper Roof Insulation Can Reduce Your Energy Costs

American Roofing Contractors Roofing Insulation

The insulation of the roof brings thermal and acoustic benefits, protects buildings against rapid fire propagation and allows owners to save energy and protect the environment.

What causes energy loss?

The main cause of energy loss is the air movement, which is generated by the difference in density between the indoor and outdoor air. In winter, when the heating systems are operating, the air inside the building is warm and dry, so it has a lower density than the air outside. When cold air enters the building, the warm air inside is pushed to the top of the building, and if the roof is not properly insulated, heat will be easily lost.

Complete roof insulation is recommended, especially for sloped roofs with attics. Specialists estimate that more than 20% of the energy loss of a house happens through the roof. The main purpose of the roof insulation is to prevent this and ensure better thermal comfort for lower energy costs. The current requirements for the thermal performance of buildings, fire safety and noise protection requires a correct design and installation of insulation on the roof.

However, if your roof is not insulated, you should consider investing in a quality insulating material, with adequate thermal conductivity coefficient (λ). This coefficient measures the efficiency of the material in resisting the loss of energy: the lower its value, the more efficient the material.
