Heat rises, and if an attic is not insulated properly, the heat needed during the colder weather is lost through your roof. Insulation ensures that during the warm weather, you will contain the cool temperature inside your home, and in the colder weather, you will be able to contain the warm air inside your home. Aside from keeping your homes more comfortable, attic insulation can also save you from extra expenses on your electric bills.

Types of materials
