Attic: The importance of attic insulation

The attic is an important interface between the living space and the building exterior. In summer heat from the sun called Solar heat gain causes the roof temperature to rise dramatically and this heat passes down into the attic space by conduction and radiation. A typical attic can reach temperatures of 140F and the objective is to stop the heat reaching the living space. In the winter we want to stop the cold outside air from reaching the living space. Attics are usually ventilated to allow hot air to escape and also to keep attic dry.
