Insulating your attic or roof can be one of the easiest and the most effective way of increasing the comfort and efficiency of your home. Spray foam insulation is the best option when adding insulation to the roof directly. However, if adding insulation to the attic floor, you can use either use blown-in cellulose or fiber glass batts.

Spray foam is ideal for roof underside, while cellulose and fibreglass batts can be added to the attic floor
