Which Type of Attic Insulation is Best For Your Home?

Ottawa Insulations11 May

Cellulose, cotton, and fiberglass attic insulation are all great options for insulating the attic of your home. But which one is the best for your home? Let's find out. Read on to find out the pros and cons of each option. Also, consider the cost and complexity of each type of attic insulation. Here are the four most popular types:

Fiberglass insulation

There are many different types of fiberglass insulation for attics, including blanket, rolls, and batts. These types are inexpensive and add a significant amount of R-value to your attic without attracting insects. You can install blanket fiberglass insulation with little effort, and faced fiberglass is coated with a vapor barrier to prevent mold and moisture. These insulation products are also durable and come with warranties that cover the cost of installation and materials.

Some people are hesitant to install fiberglass because of the risk of inhaling tiny particles of glass. As these particles can irritate the skin, they may also cause respiratory problems and other health concerns. Because fiberglass does not seal tightly around vents and edges, it may cause a variety of rashes and irritation. If you are not sure whether fiberglass is right for your home, contact an HVAC professional for advice. However, these professionals will be happy to explain the benefits and drawbacks of using it.

Fiberglass is more durable than foam and maintains thermal performance for the life of your home. Although it may require more layers of insulation, it is far superior to spray foam. Unlike spray foam, fiberglass insulation is also fire-resistant. Cellulose is a type of insulation made from recycled newspapers. It is treated chemically with ammonium sulfate to ensure it is fire resistant. It is regulated by the Consumer Product Safety Council as a fire hazard.

Cellulose insulation

Compared to fiberglass, cellulose is considered a greener material for insulating your attic. Because it's made from recycled paper, cellulose does not pollute the air in its manufacture. Plus, it uses less energy. Fiberglass contains tiny fibers that become airborne, which can contribute to air pollution. Moreover, it takes a long time to dry. The moisture it absorbs can drastically reduce the R-value and encourage mold and mildew.

Self-supported spray-applied cellulose is the most common type of insulating material. These spray-applied layers support themselves as they are applied, and are most often installed on exposed walls. However, the Commission also wants to specify that spray-applied cellulose insulation should be tested for R-value using ASTM C 1149. Manufacturers should also state the thickness of the material before using it. But the Commission has yet to issue a final rule for the material's R-value.

Because of its high density, cellulose insulation can be used in an attic. It is dense and flexible, and can conform to the shape of the attic. It slows the spread of fire and keeps out oxygen. It also provides superior comfort and reduces energy costs. This product is an eco-friendly choice for insulating your attic. If you're interested in making your attic healthier, cellulose insulation is an excellent choice.

Blanket insulation

If you're considering using blanket insulation to insulate your attic, there are some important things you need to know before you get started. First, you'll need to seal off the spaces around the attic and measure the thickness of the batts. After that, check for gaps around the framing or wooden frames. Check for tight fits around other building components. Blanket insulation is the cheapest and easiest form of insulation to install, but it's not as effective as spray foam. Make sure you wear gloves while installing it, too.

The most popular type of attic insulation is fiberglass, but there are other materials you can choose from. Some types of blanket insulation are composed of recycled materials like cotton, mineral wool, or plastic fiber. These materials are inexpensive but not as effective as foam insulation. The R-value of typical batts and rolls is usually between R-2.9 and R-3.8 per inch, and high-density blankets are between R-3.7 and R-4.

Another type of attic insulation is radiant insulation, which is made from a reflective barrier placed over polyethylene. It creates a pocket of air that minimizes the transfer of heat from the roof. As the attic receives the most sunlight, radiant insulation reduces the transfer of heat from the roof. This method is ideal for hot climates, and it can save you five to ten percent in cooling bills each year. There are several other forms of attic insulation, including blanket insulation, and both types can be done by a homeowner.

Cotton insulation

Although cotton isn't as effective as fiberglass at insulate your attic as fiberglass, it's an excellent option if you're building a green home. Not only is it a renewable resource, it is also easier to work with and poses fewer health risks than fiberglass. Cotton is also biodegradable, making it a good choice for green building projects. Listed below are the key benefits of using cotton insulation for attic insulation.

A good quality cellulose product has an R-value of about 3.5 per inch. It contains recycled materials and is less likely to cause irritation to the lungs. The only disadvantage to cellulose is its high cost. This makes it less affordable than fiberglass but is still worth considering if you want to reduce your health risks. Unlike fiberglass, cotton insulation is also easy to cut and install. Using a quality product is highly recommended.

Unlike fiberglass and mineral wool, cotton has a higher R-value than both of these materials. Fiberglass and mineral wool are both safe for use in the attic, but they pose risks to people working on the job. While cotton is less expensive, you'll have to shell out a higher price for high-quality mineral wool, which can be dangerous if inhaled. Cotton, on the other hand, has a low cost per square foot and a higher R-value than fiberglass.


There are several types of attic insulation available, including roll and batts. Roll insulation works best when you have plenty of headroom and no obstructions. Batts are both smaller and easier to handle than rolls. If you are installing attic insulation in a confined space, batts are better than rolls because they can be cut to the exact length you need. Batts also offer more square footage per package.

You can buy batts that have been unfaced to prevent moisture from accumulating between the layers. Batts that have no face will prevent moisture from escaping through gaps and will help keep your attic warm. To install a new layer, remove the old batt layer and place the new one perpendicular to it. Be sure to batt the adjacent batts tightly together without compressing them.

Batts are easy to install and service. If you need a professional to install the insulation, you may wish to hire an insulation contractor. However, you should keep in mind that professional attic repairers will have to clean up the insulation before they can install the new batts. This may result in uneven insulation and damaged insulation. If you choose to install batts, you will be able to replace a small piece of the old insulation when it needs replacement.


In residential attics, insulating material is placed on shields that will be the walls of the attic. The shields are hemmed with boards on the reverse side. The insulation material is applied in the same manner as on the exterior walls. If the attic is in a high-rise building, insulation from the inside is done by mounting the plates directly on the mineral wool. This allows the attic to be used all year round and reduces heating costs.

The process is straightforward and can be done by following some basic guidelines. First, lay out the attic floor plan. If the attic floor is wood, a vapor barrier is necessary to prevent condensation. Then, measure along the walls. You should have about 300mm of attic floor. Once you've measured the length of the walls, you can proceed to installing the insulation. Then, place vapor barrier on top of the insulation.

The thermal insulation of a plate is determined by its arrangement. A vertical arrangement of the fibers has better noise and heat preservation characteristics than a chaotic arrangement. A mineral wool consultant will determine how to place the fibers to achieve the best results. There are also different options for installing mineral wool insulation. One popular option is mineral wool. It's inexpensive and easy to install, and is often used in combination with spray insulation. However, ordinary expanded polystyrene is not fire-resistant and can emit toxic gases when combusted.

Other options

Other options for attic insulation include cellulose. This material consists of recycled paper and other materials, and contains little air pockets, making it a good choice for the attic. While some homeowners worry that cellulose might be a fire hazard, it has several benefits. The added compounds such as ammonium sulfate and borate make it more insect and fire-resistant, and it is more dense than fiberglass.

Spray foam is often considered the creme-de-la-creme of attic insulation, as it works to address the problem of heat transfer through holes and ceilings. This insulation is a foam material that expands when blown in using a hose. The material expands to fit around existing holes and provides a tight air seal. However, spray foam is expensive, and is best used in colder climates like Wisconsin, where winters are extremely cold.

Another option for attic insulation is to use rigid board insulation. This type of insulation requires no ductwork and is installed directly over the ceiling joists. This method requires fewer seams and leaves the existing insulation in place. Make sure to seal off any obvious air leak paths before installing the polyethylene. Also, make sure to make sure that electrical fixtures, such as recessed light fixtures, are sized correctly for the new depth of the ceiling.
