Homeowners today have more choices than ever before when it comes to insulation. At The Exterior Company, we work with leading manufacturers of fiberglass, cellulose and foam insulation to provide comprehensive solutions for any application.

Our technicians are fully qualified to install blown-in, batted, board or spray insulation materials. We work on walls, attics, windows and all other areas of the home where drafts may occur. 


Replacing the insulation in your home — or insulating a room that previously had none — is a worthwhile upgrade for any older property. New, energy-efficient insulation will make your home warmer in the winter and cooler in the summer. This, in turn, reduces the amount of work your furnace and A/C have to do, lowering your utility bills and extending the life of these expensive appliances.

New insulation will also add value to your home, making it a worthwhile investment both in the long run and on a month-to-month basis.   


R-values measure the ability of a material to prevent heat transfer. They are the most common way of quantifying a type of insulation's efficiency. Materials with a higher R-value will be more effective at keeping heat in the home, resulting in improved comfort and lower energy bills.

While understanding R-values and choosing an appropriate product is important, even the best insulation materials won’t deliver the efficiency they promise if they are not installed correctly. That’s why it’s so important to work with a knowledgeable contractor. That’s where The Exterior Company comes in.
