Fiberglass Insulation: Batts vs. Loose Fill

Fiberglass insulation is an excellent insulation material that is cost effective, energy efficient, and has acoustic properties. There are two types available: batts and loose fill.

Fiberglass insulation is an excellent insulation material that is cost effective, energy efficient, and has acoustic properties. According to the United States Department of Energy, it features between 40 and 60 percent recycled content, making it an environmentally sustainable product.

Additional benefits associated with fiberglass insulation include its thermal performance and moisture and fire resistance properties. Depending on the type, this insulating material either comes in specific R-Values – a measure of its resistance to heat flow – or can be blown in to meet ENERGY STAR’s recommendation.

There are two types available: batts and loose fill. Ideally, batt insulation should be professionally installed, as proper fit is crucial for benefitting from the material. Because loose fill insulation requires specialized equipment, it must be installed by an experienced, licensed insulation contractor.

Select the Right Type for the Application

Batt Insulation

A defining feature of batt insulation, also available as rolls, is its versatility. They can be installed in attics, wall cavities, and floor cavities and to a depth that meets ENERGY STAR’s recommended R-values. This insulating type must fill the area where it is being installed, meaning there can be no gaps, ensuring maximum performance.

Blown-in Loose Fill

A more efficient alternative to batts and rolls is loose fill fiberglass insulation that is blown into the attic space using truck-mounted equipment. This installation technique allows the material to fill in gaps and tight areas, where installing batts would be more difficult. Loose fill materials, when professionally installed, offer the same R-values as other fiberglass insulation types.

Fall Home Maintenance

The dog days of summer will soon be replaced by fall’s cooler weather and stunning canvas. Fall is an ideal time to check these tasks, including ensuring adequate levels of fiberglass insulation in the attic, off your home maintenance checklist.

Inspect the Roof

Inspect the roof for any storm damage, abnormal wearing, or signs of aging. Do this from the ground by using binoculars, if necessary, and walking around the house’s perimeter. You should also check in the attic for light infiltration or damp fiberglass insulation. The latter may indicate a roof leak and insulation will need to be replaced by an experienced insulation contractor.

Fall Home Maintenance

Clean the Gutters

The gutters, if your home has them, direct rainwater away from your foundation. Dead leaves, tree needles, and the flyaway Frisbee can impact water flow by causing a blockage should they build up over time. Water then can damage your roof, insulation, siding, and foundation. Scoop out the gunk and then rinse the gutters each fall and spring – more frequently if your landscape features a lot of trees.

Check for Air Leaks

According to the U.S. Department of Energy, heat gain or loss through windows accounts for between 25 and 30 percent of your heating and cooling energy use, and they are not the only thing costing you money.

Air leaks can also cause a spike in your heating and cooling costs.

Because the source of air leaks can be challenging to identify without the correct tools, consider having an energy audit done by a licensed insulation contractor. It is essential to seal air leaks and insulate to see savings.

Change Your Filters

Routinely replace the filters in your heating, ventilation, and air conditioning (HVAC) unit. A good rule of thumb is to replace inexpensive filters every 30 days for maximum efficiency.

Now more than ever before, it is recommended to select high efficiency particulate air (HEPA) filters, which can go about 90 days before changing them is necessary.

A HEPA filter can effectively remove 99.97 percent of airborne particles such as dust, pet dander, and bacteria with a size of 0.3 microns. They can help improve indoor air quality and comfort. You can find replacement filters online or in stores.

Improve Fiberglass Insulation Levels

Another issue that may impact your energy efficiency is insufficient levels of fiberglass insulation. Fiberglass, whether loose fill or batts, provides good thermal performance at an attractive price point. It is also made of a significant amount of recycled content.

Uninsulated attics in valley homes should be insulated with an R-value – a measure of the material’s ability to resist heat transfers – between R30 and R60. Attics with existing insulation should meet a value between R25 to R38.

Three Advantages of Fiberglass Insulation

Since its introduction in the late 1930s, fiberglass insulation has remained one of the most popular insulating materials, and with good reason. Pre-cut rolls or batts and blown in loose-fill are the two most frequently sold types. It can be applied to attics, walls, floor cavities, and basement rim joists.

Because a tight fit is required for optimal energy efficiency, it is essential to hire an experienced and licensed insulation contractor, such as Banker Insulation. It is also recommended that any air leaks be sealed to ensure maximum efficiency.

Fiberglass insulation is predominantly manufactured using up to 60 percent recycled container glass, according to the U.S. Department of Energy, thus freeing landfill space. The glass is woven into tight fibers that trap pockets of air to slow the transference of conditioned, whether heated or cooled, air.

Ways Fiberglass Insulation Can Benefit You

Cost Effective

Fiberglass insulation is the ideal choice for budget-conscious consumers. There are plenty of options in terms of R-values and types that residential and commercial consumers can select from while remaining within budget. Another cost effective option to consider, especially if moisture is a concern, like in a basement, is to choose faced insulation. That insulation uses a vapor retardant to help prevent condensation.

Sound Dampening

Fiberglass insulation is offered in different thicknesses with different degrees of sound absorption. While noise reduction increases with depth, this insulating material will not block sound transmission. There are, however, products available with added sound attenuation. These products are ideal for several applications, including home theaters and home offices, as well as other areas where you’d like to block noise.

Thermal Resistance

The R-value for fiberglass ranges between R-8 and R-40. These values measure the thermal resistance – how well the material resists heat – with a higher number offering the best performance. Contact an insulation contractor to identify the correct R-value for your area’s climate as well as where insulation is required. Make sure the material provides optimal energy efficiency by having it professionally installed.
