Types of Insulations for your Home Attics

Most attics are not appropriately insulated with the most effective ways to reduce heating and cooling costs. Attic insulation comes in a few different types: loose-fill, spray foam, rolls, and batts are some common types.

What are the Common Types of Attic Insulations?

The attic is one of the most critical places in the house to insulate. Insulation helps to keep the attic cool in the summer and warm in the winter, protecting the home from extreme weather conditions. Also, insulation helps cut down on noise pollution and can improve the quality of the air inside by catching dust and other allergens.

Cellulose Insulation

When choosing insulation material for the attic, it is essential to consider the climate. For example, homes in warmer temperatures will need different insulation than homes in colder climates. Proper attic insulation is critical for keeping your home comfortable and energy-efficient all year.

The most common type of attic insulation is blanket insulation, which comes in rolls or batts that are easy to install. Blanket insulation is made from various materials, including fiberglass, cellulose, and wool.

Each type has pros and cons, so choosing the right one for your needs is essential. There are many types of insulation material available on the market.

Different Types of Attic Insulations

Attics are essential for maintaining your home’s temperature and energy efficiency. It is crucial to choose the right type of insulation for your attic.

  • Foam insulation is sprayed into place and then expands to fill any gaps.
  • Batts are pre-cut strips of insulation that fit snugly between the joists in your attic.
  • Blown insulation is loose material blown into place using a particular machine.
  • Roll insulation comes in long rolls that can be cut to fit the dimensions of the attic.

Various types of insulation can be used to achieve different levels of insulation. During the summer, attics can become very hot, and the heat can transfer into your living space. Proper insulation helps keep the heat out by creating a barrier between the attic and the rest of your home. In winter, attic insulation helps keep the heat in, preventing warm air from escaping through the roof.

Fiberglass Batts

Fiberglass insulation is made from recycled glass spun into fibers and bonded together with a resin. Most of the time, fiberglass batts are put in between the studs of a wall or ceiling. They can be used in both new construction and renovations. Many attics are insulated with fiberglass batts. The batts are available in various widths and thicknesses to fit most attics.

Fiberglass Insulation

Fiberglass batts are easy to install and provide good insulation. However, they can be difficult to remove and can irritate the skin. A vapor barrier should be placed over the fiberglass batts to keep water from condensing.

Loose-fill Fiberglass

Loose-fill fiberglass is similar to fiberglass batts, but instead of being installed in pre-cut pieces, it is blown into the attic space by a particular machine. It is a popular choice for attics and other hard-to-reach places. The small, lightweight pellets are easy to handle and can be blown into attics using a particular machine.

R-value of Fiberglass Insulation

Once in place, the fiberglass helps to keep homes warm in the winter and cool in the summer by trapping air in the tiny spaces between the pellets. Also, fiberglass insulation blocks noise well, making it a good choice for homes near airports or busy streets.


Cellulose is typically installed using the same methods as fiberglass insulation. It is better at keeping heat than fiberglass insulation because it has a higher R-value. Cellulose is a type of dietary fiber that is found in plant foods.

R-value of Cellulose

It is an essential component of the cell walls of all plants and gives plants their structure and strength. It is a crucial part of our diet but has many other uses. For example, blown-in cellulose is used as insulation in attics. It can also be processed into paper and other products.

Rigid Foam

Rigid foam is available in boards or sheets and can be used in new construction and retrofit projects. It has a high R-value and can help save money on energy costs by making it harder for heat to escape through the attic. Rigid foam is a type of plastic that is made from petroleum products.

Foam board insulation

It is typically sold in sheets four feet wide and eight feet long. The foam board insulation can be cut to fit any space and glued or taped. Rigid insulation panels are better because they have a high R-value and stop heat from moving through them. Also, the foam doesn’t let air or water through, which makes it an excellent choice for attics and other places where insulation is essential.

Spray Foam

Spray foam is made from polyurethane or acrylic resin and sprayed onto the attic floor using a machine. This type can be used in new construction and retrofit projects. Spray-foam attic insulation has a high R-value and can help make an airtight seal, preventing heat from escaping in the winter. It is an insulation type applied as a liquid and then expands to form a solid barrier. It is commonly used in attics and other areas where insulation is needed.

Spray Foam

Spray foam has several advantages over different types of insulation. It is very effective at preventing air leaks. It helps to keep attics cooler in the summer and warmer in the winter. Spray foam is easy to apply and can be done by homeowners without special training.

Mineral Wool

Mineral wool is made from rock wool or slag wool fibers spun into a batting material. Mineral wool insulation comes in different R-values, which show how well it blocks heat flow. Mineral wool batts are often used in attics because they are easy to install and have good soundproofing properties. Mineral wool is insulation commonly used in attics and other areas with limited space.

Mineral Wool

It is made from recycled glass, stone, or slag and is very effective at preventing heat loss. Mineral wool is also resistant to fire and mold, making it an ideal choice for areas where safety is a concern. In addition, mineral wool is very easy to install and can be cut to fit any space. As a result, it is one of the most popular types of insulation on the market.

Recycled Denim

One way to ensure your home is eco-friendly is to use recycled denim insulation. This type is made from post-consumer denim waste, meaning it would otherwise end up in a landfill. In addition to being eco-friendly, recycled denim insulation has many other benefits. It is non-toxic and does not off-gas, making it safe for use in attics and other enclosed spaces.

Denim Insulation

Denim is also an excellent insulator, providing good acoustic and thermal performance. As a result, recycled denim insulation can help you save money on heating and cooling costs. Best of all, it provides these benefits without harming the environment. So if you’re looking for an eco-friendly way to insulate your home, consider recycled denim insulation.

Radiant Barrier

Radiant barrier insulation is attic insulation that reflects heat rather than absorbs it. Most of the time, aluminum foil is stuck to the underside of the roof decking to make a radiant barrier. Radiant barrier insulation can be added to other types of attic insulation to make them work better. If you’ve ever been in an attic on a hot day, you know how uncomfortable it can be.

Radiant Barrier

The heat can be intense and challenging to breathe. Attics can reach temperatures of 150 degrees or more. That’s why it’s essential to have a radiant barrier installed in your attic. A radiant barrier is a layer of insulation that helps to reflect heat away from your home.

It’s usually made of foil or reflective material, and it’s installed between the rafters in your attic. As a result, it helps keep your attic cooler, making your home more comfortable and energy-efficient. Radiant barriers are a vital part of any insulation system, and they can help improve the comfort of your home while saving you money on energy costs.

Many different insulation materials can be used in attics, and the most popular options are fiberglass, cellulose, and spray foam.


Polyisocyanurate insulation is a type of foam insulation often used in attics. The foam is then treated with a blowing agent, which helps to expand the foam and make it more effective as an insulation material. It is better than other types of insulation in several ways, such as its ability to stop mold and mildew from growing. Also, this material doesn’t settle or get smaller over time, making it an excellent choice for attics and other places with limited space.


Polyurethane is a versatile insulation material used in attics, walls, and floors. It is made from two liquids mixed and then sprayed onto the surface to be insulated. The material expands as it dries, filling any cracks or voids in the surface. This makes it an effective barrier to heat loss, and it also helps to reduce noise levels.

Polyurethane insulation has several advantages over other types of insulation, including its high R-value and ability to form a tight seal. It is also easy to set up, making it a popular choice for new construction and remodeling.

Spray foam types

Rock Wool

It is often used in industrial and business settings, but it can also be used in the attics of homes. Rock wool insulation has a high R-value and is resistant to fire and mold growth. Rock wool is made from rocks that have been melted down and spun into fibers. It is commonly used in attics and walls to keep homes warm in the winter and cool in the summer.

Rock wool is an excellent insulator because it can trap heat very effectively. In addition, it is also fire-resistant and does not allow moisture to pass through it, which can help prevent mold growth. Rock wool is an excellent insulator that can help keep your home comfortable all year.

Recycled Newspaper

Recycled newspaper insulation may be the right choice if you’re looking for a sustainable and cost-effective way to insulate your attic. Before being used as insulation, the paper is torn up and treated with a solution that stops fires. Newspaper insulation can be used in attics, walls, and floors, and it’s an effective way to keep your home warm in the winter and cool in the summer.

Compared to other types of insulation, that made from recycled newspapers is cheap and easy to install. Plus, it’s an environmentally friendly option since it recycles old newspapers that would otherwise end up in landfills. If you’re looking for a green way to insulate your home, recycled newspaper insulation is something to consider.

Phenolic Resin

In homes, attics are a common place for insulation material. This is because attics are typically under the roof and are not heated or cooled like the rest of the home. As a result, attics can get extremely hot in the summer and very cold in the winter. Insulation keeps attics cooler in the summer and warmer in the winter, making them more comfortable all year.

Ceiling Spray Weather Foam

Phenolic resin is one type of material commonly used in attics. Phenolic resin is made from a combination of phenol and formaldehyde and is known for its high resistance to heat and fire. In addition, phenolic resin is also resistant to mold and mildew, making it an ideal choice for attics.

How to Choose Insulation for an Older Home?

When considering whether to add insulation to an existing home, attics are often the first place homeowners think of. Indeed, attics are a prime spot for insulation, as they tend to be one of the most significant sources of heat loss in a home. 

Ceiling Fiberglass Insulation

One of the biggest problems with older homes is that they often lack proper insulation. This can make attics and other areas of the house extremely hot or cold, depending on the season. Not only is this uncomfortable for residents, but it can also lead to higher energy bills.

Topping Existing Insulation

If your attic already has existing insulation, topping it with more can help to further improve your home’s energy efficiency. It’s essential to choose the right type for your attic, though. If it is made of fiberglass, you’ll want to use a different material for the top layer. This is because fiberglass doesn’t stick well to other materials, so the new layer of insulation could end up falling off. Instead, opt for insulation made of blown cellulose or spray foam.

Older homes often have single-pane windows, which can significantly cause heat loss. By adding a layer of film or foam to the inside of these windows, homeowners can dramatically improve their home’s energy efficiency. Insulation can also be used in crawl spaces and basements, which can help keep heat from escaping through the home’s foundation. By looking at insulation, homeowners can make their homes more comfortable and use less energy.

Attics are often the first place to start when insulating an older home. Most attics aren’t well insulated, so they let a lot of heat out in the winter and let in a lot of heat in the summer. Adding insulation to the attic can help reduce energy bills and make your home more comfortable year-round.

Several different types of insulation are available, so it’s essential to choose the right one for your needs. Fiberglass insulation is often used in attics because it is easy to install and doesn’t cost too much. However, foam insulation may be better if you’re concerned about air leakage. Whichever type you choose, make sure it has a high R-value to ensure maximum efficiency.
