Insulation refers to the material used to prevent loss or gain of heat. It serves as a barrier between two spaces in order to control the temperature variances of a given structure or building. The insulation can come in the form of either a fiberglass or rock substances that were heated to become fine, hair-like materials. There are also some structures that use spray foam or insulation boards as insulation material.
A well-insulated home and attic can help you to save as much as 50% off your electricity bill. This was according to the US Dept. of Energy. For instance, if your attic does not have insulation, the heat from your home quickly escapes at your roof. This is already tantamount to wasted energy. Insulating your attic can help to prevent the loss of heat, and thus, your home will feel warmer in winter while it’s cooler during summer.
The attic insulation cost will depend on the size and the insulation material. An average-sized attic with an area of 1,200 square feet costs between $1,700 to $2,000 to be insulated with a fiberglass material or blown-in cellulose.
Energy Audit Before Getting Insulation In Your Home
Before you get your attic insulated, it’s recommended to have an energy audit. This is to determine in which part of your home you are losing energy. A lot of energy companies can provide this service. This is a great way to determine the type of insulation that’s suitable for your home. The audit should cost you around $150.
Cost Factors Before Installing Insulation
The type of insulation material is the biggest factor in determining the attic insulation cost. These days, fiberglass or blown-in cellulose often has similar prices. However, the cost is constantly changing. Several years ago, the fiberglass material costs twice as much as the cellulose. Moreover, rock wool insulation or rolled fiberglass insulation is the least expensive material used for insulation. On the other hand, foam boards and spray foams are often the most expensive and are rarely used in insulating the attic because it’s very expensive.
A lot of things could cause the attic insulation cost to vary. Among these is the size of your attic, existing insulation, as well as the number of ventilation fans that are on your roof. If your attic has an existing insulation, it must first be removed before installing a new one. Insulation must be installed around the openings of the vent fans.
Labor And Installation
Installation of the insulation material must be done by a licensed contractor. Most of the licensed insulation companies charge $0.95 per foot for the labor.
