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.

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.

How to Ensure Wintry Warmth in Arizona and New Mexico

Here are some tips, including hiring an insulation contractor, about energy audits and insulation installation that will help keep your home warm this winter.

Updated January 2024

When winter draws near, fellow Arizona and New Mexico homeowners prepare for the colder months ahead. Even though our desert climate is renowned for its scorching summers, the winter months can still bring chilly temperatures, prompting us to seek ways to keep our abodes warm without driving up our energy bills. Fortunately, there are numerous strategies and winter energy-saving tips that can help us achieve a cozy home environment while also being mindful of energy conservation and cost efficiency.

Seal the Warmth: Tips for Improving Insulation

Two of the biggest contributors to high energy bills are inadequate or damaged insulation and air leaks. When your home’s insulation levels fall below ENERGY STAR’s recommended R-values or become damaged by pests or water, the insulation can’t adequately resist heat flow and becomes less effective. While air leaks around your windows, doors, and other areas of your home allow heated air to easily seep out and cold air to seep in.

The best way to ensure your home has the right amount of insulation in the right place is to hire an insulation contractor to assess your current insulation levels. A professional can identify areas where your insulation may be lacking, such as walls, attics, and crawl spaces, recommend necessary upgrades, and provide you with an accurate cost estimate.

As for air leaks, seal drafts with caulk and weatherstripping to reduce heat loss and cold air infiltration and consider undergoing a home energy audit. During an audit, specialized equipment is used, such as a blower door test and infrared camera, to pinpoint air leaks and provide you with a list of energy efficient home improvements.

Take the time now, before winter weather hits, to invest in insulation upgrades like fiberglass blown-in wall insulation, spray foam insulation (that insulates and air seals in one step), or extra attic insulation. And be sure to take advantage of any tax credits and rebates that may be available to you.

Mastering Winter Warmth: Strategic Heating & Thermostat Use

Smiling woman using a smart thermostat. reports that the average American household’s heating system accounts for almost 30% of their total utility bill. This makes it even more important to take advantage of the variety of ways to strategically heat your Southwest home or business, utilizing both technology and applying other simple measures.

During the winter months, it’s important to set your indoor temperature to an ideal setting, preferably 68°F during the day and 65°F at night. A simple programmable thermostat will let you “set it and forget it” while a smart thermostat adjusts temperatures around your schedule, preferences, and the weather. You’re able to monitor and control your smart thermostat using your smartphone. Both thermostats are effective choices that reduce energy consumption without sacrificing comfort.

Also consider these other strategic heating measures to encourage energy conservation:

  • Take advantage of zone heating. Closing doors and vents in unused rooms will allow you to concentrate warmth where it’s needed most, rather than heating your entire house or building.
  • Reverse the direction of your ceiling fan. Doing so will draw air up, push the heated air into the corners of your room and send the warm air back down to heat up your family.
  • Lower the temperature of your water heater. Keep it set at no higher than 120°F to help save energy.

Let the Light In: Efficient Window Options

Windows are another potential source of heat loss during the cold winter months. Investing in energy efficient double or triple pane windows can improve insulation and reduce cold air infiltration. South-facing windows are particularly beneficial, as they allow for maximum solar heat gain during daylight hours. To further enhance insulation, you can draw thick curtains and blinds at night to trap warm air indoors, while opening them during sunny days to naturally heat your home. Taking these steps can help warm your home or business without turning the heater up and, in turn, help lower your energy consumption.

Everything You Need to Know About Cellulose Insulation

When used to insulate an attic, cellulose insulation will help regulate your home’s temperatures, thereby improving your comfort. It will also help save you money on high cooling costs in the summer and heating expenses in the winter.

According to ENERGY STAR, you can expect a ten percent savings on annual energy bills when you combine insulation installation with effective air sealing techniques, such as applying caulk and adding weather stripping materials around the windows and doors of your home. A professional energy audit is the most effective way to identify air leakage.

Professional installation is essential for reducing energy costs. An insulation contractor will ensure that all materials are installed correctly and at the proper depths to achieve ENERGY STAR’s recommended R-values. R-values refer to how well the insulating material can resist heat flow.


What is it?

Cellulose is a paper-based insulating material. It usually contains more than 80 percent of recycled paper products, making it an excellent choice for environmentally conscious consumers. Because cellulose is a loose fill material, it can be blown-into attic spaces and densely packed in wall and floor cavities. Blown-in insulation, like cellulose, requires professional installation from an insulation company.

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.

The Basics of Home Energy Audits

A home energy audit, when performed by an experienced insulation contractor, can help determine where your home is consuming the most energy and identify areas for improvement. It is a cost effective way to detect air leaks, inadequate insulation, and other inefficiencies that may be causing you to spend more money to heat and cool your home than is necessary. The contractor will also provide you with a prioritized list of recommended upgrades designed to improve the efficiency and comfort of your house.

How to Prepare for an Audit

The best things you can do are make a list of energy-related concerns and compile copies of your most recent electricity bills before the insulation contractor arrives. Are you signed up for paperless billing? You can download and print invoices by logging into your account. These are useful for determining your energy use each month. Ideally, you should also open your curtains or blinds and, if applicable, clear any clutter around your attic and basement doors to ensure access.

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.

Spray Foam vs Fiberglass Insulation

You’ve conquered the busiest season of the year, and now it’s time to tackle that insulation problem, so spray foam insulation or fiberglass insulation? Banker Insulation has previously written about the best applications for spray foam insulation, so let’s talk about the difference between these two popular, energy-efficient insulation types.

Spray Foam Insulation

The installation of spray foam is in attics, roofing, and interior wall cavities. Spray foam is used because it expands and fills even the smallest gaps. If combined with attic air sealing, spray foam becomes a moisture barrier reducing the risk of mildew or mold.

When combined with protective coatings and other materials during construction, spray foam can produce a cool roof. In an environment like Phoenix, cool roofs can reduce your overall cooling cost.

If you’re constructing a new home or you’re renovating, this is a perfect time to use spray foam insulation in your walls. This type of insulation can have benefits such as soundproofing, energy efficiency, and better comfort within your home.

Fiberglass Insulation

Fiberglass comes in the rolled form or loose fill that’s blown in. The loose type is used in areas such as attics, walls, and floors like spray foam. This type of insulation traps air in glass fibers that slows the transfer of heat into your home or business. Another benefit of fiberglass is that it’s low-cost insulation.

Fiberglass batts can be installed without professional assistance, but it’s highly recommended that you have a professional insulation company install it for you. Professionals will have all the proper protective gear, and there will be less of a risk to you and your family. Another benefit is that the installation cost is usually cheaper than spray foam.

Fiberglass has been around the longest, which is one reason that many people choose it over spray foam because it’s more familiar. Fiberglass also tends to make less of a mess than spray foam.

Cons of Spray Foam and Fiberglass

There are three cons that homeowners and business owners should be aware of when considering spray-in insulation: cost, difficulty to apply, and the mess. While the cost to install is a drawback, the amount of money you save in the long run makes up for this.

For fiberglass, there are two disadvantages you should be aware of: it’s not as efficient and settles faster. While you’ll probably save money on the installation, you’re more likely to have to install new insulation sooner, and you may not save as much on your utility bills.
