However, the former would be significantly less expensive compared to spray foam insulation as well as the other types. Popularly, fiberglass insulations in totality are known as those feathery layers of sheet covering exposed wall studs or ceiling rafters.

In addition, fiberglass insulation systems can be mounted using various machineries but frequently, they are installed by hand as batts which are precut sections or via rolls which are sheets that stretch up to 40 feet. This is apparently a good thing because Do-it-Yourself enthusiasts are able to save tons of money for labor since they are able to install them with ease and without the need of special tools or hiring further skilled persons to do the job.

Now, in order to understand how much does fiberglass insulation cost in general, one must know the r-value of the material being used in finishing the insulation tasks at hand. An r value is the ability of the insulation system to resist heat. Consequently, those systems with higher R values allow them to provide more heat resistance per inch of the material. Depending on the preference of thickness and price points, homeowners and concerned people in the said area of subject must consider first the required r-value in addition to their insulation needs and requirements. Note that R values may range from 11 to 38 in figures.

Accordingly, the price of a single roll of reflective insulation may vary depending on its r value. Rolls that stretch up to 40 feet long can cost at an average, $0.25 to $0.75 per square foot.

Installing the Insulation and Its Relating Amounts

Now that the known average cost of a single roll or batt of fiberglass is already laid out on the table, it is now appropriate to discuss how much it will cost to insulate a single part of the house or its entirety.

According to statistics and several studies done across the American regions, an average residential home may be measured around 2500 square feet and most of which are two storey buildings. However, not all households would opt to insulate the entire house but rather choose only a portion of the entirety – such as walls, roofs, attics, and garages. This case will pretty much be based according to your preferences or personal choices, or even be based on your estimated budget as well since this will affect the overall prices of the insulation works.

  • Walls

When insulating walls, a simple hole is cut and insulation is blown in for the hole to be then sealed properly. At a budget of $1 per square foot you are know enabled to enjoy the convenience of a warmer ambiance during winters and more energy-efficient rooms during summer seasons.  In this situation, batt insulations are more appropriate than the rolls since the overall batt insulation cost is most of the time cheaper than fiberglass rolls.

  • Roofs

Roofs require a more tedious process. They must be sealed first prior to the insulation by filling gaps and closing vents, just to name a few. Harsh conditions such as heavy rain or extreme heat during the summers will take a toll in the fiberglass insulation, degrading it until it no longer serves its purpose. Because of this, constant monitoring of the roof insulation is needed to maintain its efficiency.

Roof insulation will give comfort to home owners giving them warmer climates during the winter and a cooler attic during the summer. Thus, it will most probably cost you a total of $1,500 for the labor and relating costs since it requires more work and because it has a larger space to fill.

  • Garages

Insulating garages is also a different story. If you desire a warmer garage, an option would be to insulate the doors with fiberglass roll. The procedure is fairly simple and will only take a few hours to complete. Doing so on a 9 foot door will cost you about $200 in totality.

A household crawl space can also be insulated depending if its ventilated or not. However, it should be taken into consideration that when you opt to insulate the crawl space, moisture should be removed. When insulating a well ventilated crawl space, fiberglass batts are suitable. Price estimates will vary depending on the length and width of the crawl space. An estimated cost of $300 will suffice for large spaces.

  • Attics

Lastly, when you intend to attain a warm attic in the winter, you may have to spend more compared to the ones above. Do-it-yourself enthusiasts will frown upon this case because it requires professional help. The cramped and dusty space will definitely take a toll on you so this is not advisable for newbies. It’s a good thing though that there are a lot of competent contractors who can do the job for you at a reasonable price. For the most part, an estimated cost of $1,300 to $2,000 is enough for insulating an entire attic. Insulating an attic can bring about a lot of benefits especially in reducing your electricity bills and increasing the home’s R values.

Indeed, insulation is very useful in any household. Consequently, fiberglass is one of the best options when deciding to have insulation inside your homes because it is way cheaper and it works its wonders in reducing energy consumption and airflow. Moreover, it does not pose any health concern.
