What Is Fiberglass Insulation?
Fiberglass is a common type of insulation material that is made from very fine glass fibers. It is available in various forms, including blanket (batts and rolls), loose-fill, rigid boards, and duct insulation. To create fiberglass insulation, manufacturers melt glass and then spin or blow it into fibers, which are then formed into the desired shape. Many manufacturers use between 40% to 60% recycled glass content in their fiberglass insulation products.
If you’re concerned about the potential health risks associated with formaldehyde in insulation, you’ll be happy to know that some companies, such as Johns Manville, manufacture blow-in insulation that is formaldehyde-free. This means that the insulation is made without using formaldehyde, a chemical that is sometimes used in insulation products and has been linked to health problems in some studies. By choosing formaldehyde-free insulation, you can help ensure that your home is safe and healthy for you and your family. Click her to see which brands we use that are formaldehyde-free
What Is Cellulose Insulation?
Cellulose insulation is made from recycled paper products, primarily newsprint, and has a very high recycled material content, generally 82% to 85%. The paper is first reduced to small pieces and then fiberized, creating a product that packs tightly into building cavities.
Manufacturers add the mineral borate, sometimes blended with the less costly ammonium sulfate, to ensure fire and insect resistance. Cellulose insulation, when installed at proper densities, cannot settle in a building cavity.
Cellulose insulation is used in both new and existing homes, as loose-fill in open attic installations and dense packed in building cavities such as walls and cathedral ceilings. In existing structures, installers remove a strip of exterior siding, usually about waist high; drill a row of three-inch holes, one into each stud bay, through the wall sheathing; insert a special filler tube to the top of the wall cavity; and blow the insulation into the building cavity, typically to a density of 1.5 to 3.5 lb. per cubic foot. When installation is complete, the holes are sealed with a plug and the siding is replaced and touched up if necessary to match the wall.
In new construction, cellulose can be either damp-sprayed or installed dry behind netting. When damp sprayed, a small amount of moisture is added at the spray nozzle tip, activating natural starches in the product, and causing it to adhere inside the cavity. Damp-sprayed cellulose is typically ready for wall covering within 24 hours of installation. Cellulose can also be blown dry into netting stapled over building cavities.
What Is Mineral Wool Insulation?
Mineral wool insulation, also known as rock wool insulation, is a type of insulation made from natural minerals like basalt or diabase. It is a man-made material that contains an average of 75% post-industrial recycled content, making it an environmentally friendly option. Mineral wool insulation is naturally fire-resistant and does not require additional chemicals to achieve this property.
Mineral wool insulation products come in various forms, such as board, batt, loose-fill, spray-applied, and pipe insulation. Whatever its form, mineral wool insulation resists mold, fungi, and bacteria growth because the material is inorganic. It also offers enhanced protection against damaging moisture. Mineral wool insulation is widely used in residential and commercial buildings as it is non-combustible and fire-resistant up to about 1,400 degrees.
Moreover, mineral wool insulation retains heat well and traps air, which slows the transfer of heat. It has a higher R-value per inch when compared to fiberglass batts, making it an excellent insulation option. Mineral wool insulation is available as blanket (batts and rolls) and loose-fill insulation, making it easy to install in a variety of settings
Blow In Insulation Also Known as Loose fill Insulation
Blow-in insulation, also known as loose-fill insulation, is a popular choice for attic insulation and wall insulation due to its cost-effective effectiveness. It’s made from materials such as fiberglass, cellulose, or mineral wool and is applied using an insulation-blowing machine to fill gaps, cracks, and crevices in your attic or walls. This method of application is used to fit insulation on your attic floor in ceiling joists. The R-value of blow-in insulation is a measure of its effectiveness in regulating temperature, with higher R-values indicating better insulation performance. Depending on the location of the blow-in insulation, a different layer of material may be required. If you’re looking for options for blow-in insulation, we can help you choose the best materials for your specific needs.
This insulation is blown into ceiling joists and attics and is made from Fiberglass, Cellulose or mineral wool. It is great for filling up any gaps, cracks or crevices in your house. We commonly use blow in insulation for attics because of the easy application and thermal properties it provides.
spray foam insulation and the different types:
Spray foam insulation is a type of insulation that is applied as a liquid and then expands to fill the space it is sprayed into. It is made by mixing two chemicals, polyol resin and isocyanate, which react when combined to create a foam that adheres to surfaces and expands to fill gaps and cracks.
There are two main types of spray foam insulation: open-cell and closed-cell. Open-cell spray foam insulation is less dense and has a spongy texture, while closed-cell spray foam insulation is more dense and has a harder texture. Here are some key differences between the two types:
- R-value: Closed-cell spray foam insulation has a higher R-value per inch than open-cell spray foam insulation, meaning it provides better insulation per inch of thickness.
- Water Resistance: Closed-cell spray foam insulation is more water-resistant than open-cell spray foam insulation, making it a better choice for areas that are prone to moisture.
- Cost: Closed-cell spray foam insulation is generally more expensive than open-cell spray foam insulation, due to its higher density and better insulation properties.
In addition to these two main types, there are also hybrid spray foam insulation products that combine open-cell and closed-cell foam. These products are designed to provide the benefits of both types of foam, such as improved insulation and moisture resistance.
Overall, spray foam insulation is a versatile and effective insulation option that can be used in a variety of settings, including attics, walls, and crawl spaces. If you’re interested in installing spray foam insulation in your home, it’s best to consult with a professional insulation contractor to determine which type of spray foam insulation is best for your needs.

Attic Air Sealing and Insulation Removal
Attic Air Sealing
Attic Air Sealing is the process of identifying and sealing air leaks in the attic to prevent unwanted air movement between the living space and the attic. Air leaks can occur through gaps, cracks, and holes in the attic floor, which can allow warm air to escape during the winter and hot air to enter during the summer. By sealing these leaks with caulk, spray foam, or other materials, homeowners can improve the energy efficiency of their homes and reduce their heating and cooling costs. According to the U.S. Department of Energy, air sealing can save homeowners up to 20% on heating and cooling costs 1. In addition to reducing energy consumption, attic air sealing can also improve indoor air quality, prevent moisture problems, and increase the lifespan of HVAC equipment 2.
Â
Insulation Removal
is the process of removing old or damaged insulation from a building’s attic, walls, or floors. There are several reasons why insulation removal may be necessary, such as when the insulation has become contaminated with mold, pests, or other pollutants, or when it has deteriorated over time and is no longer effective. In some cases, insulation removal may also be necessary before installing new insulation, especially if the old insulation is incompatible with the new material or if there are safety concerns. Insulation removal is typically done by a professional contractor using specialized equipment, such as a vacuum or blower, to safely and efficiently remove the insulation without causing damage to the building or exposing occupants to harmful particles.

Acoustic Performance
Spray foam Insulation
Spray foam insulation can provide good acoustic performance by reducing sound transmission through walls, ceilings, and floors. The foam fills gaps and cavities, creating an airtight seal that reduces the amount of noise that can pass through. The specific acoustic performance of spray foam insulation can vary depending on the type of foam used, the thickness of the application, and the construction of the building.
Open-cell spray foam insulation has a lower density than closed-cell spray foam insulation, which can make it a better option for absorbing sound waves. Closed-cell spray foam insulation, on the other hand, is denser and can provide better sound insulation by blocking sound transmission.
It’s important to note that while spray foam insulation can provide good acoustic performance, it may not be the best option for every situation. Other factors, such as the thickness of the walls and the type of construction, can also affect the acoustic performance of a building. A professional insulation contractor can help determine the best insulation solution for a particular building and its acoustic needs.
Batt Insulation
According to Knauf Insulation, fiberglass batt insulation with innovative ECOSE technology can provide good acoustic performance by reducing sound transmission through walls, floors, and ceilings. Owens Corning also provides a technical data sheet for their Sound Attenuation Batts insulation, which shows the acoustic performance of their fiberglass batt insulation in various wall systems.
However, it’s important to note that the acoustic performance of batt and roll insulation can vary depending on the specific type of insulation used, the thickness of the application, and the construction of the building. In general, batt and roll insulation can provide some level of acoustic performance by reducing sound transmission through walls, floors, and ceilings, but it may not be as effective as other types of insulation specifically designed for soundproofing.
Overall, while batt and roll insulation can provide some acoustic performance, the specific level of performance will depend on the specific type of insulation used and the construction of the building. It’s important to work with a professional insulation contractor to determine the best insulation solution for a particular building.
