Can Attic Insulation Help in Summer as well as Winter?

Your attic and roofing insulation works in a way similar to a thermos – it keeps the air in your home warm in winter and cool in summer by preventing heat loss and heat transfer between your building interior and the outdoor environment.

If uninsulated, your attic floor is the surface through which most of the energy loss in your home will take place. Warm air is drier, therefore lighter than cooler air, that’s why it also tends to move upwards. Without attic insulation, the warm air in your rooms will rise without encountering any obstacle and will eventually leave your building through the roof. Insulation installed on the attic floor and on the attic walls, and roof,  prevents all that from happening, keeping your home comfortably warm in winter.

Attic and roofing insulation is just as important in summer, but for different reasons. The component of the building envelope that receives the most heat is the roof and, with it, the attic. When the sun shines really strong, some of the heat absorbed by the topmost layer of your building is transferred towards the lower layers. Livermore roofing insulation specialists confirm that your attic and roof insulation can prevent that from happening, thus keeping your building interior comfortably cool even on the hottest summer days.
