Fiberglass Batt Insulation

Fiberglass batt insulation is one of the most popular types of insulation for attic ceilings. It comes in pre-cut batts that fit between the joists and is easy to install. It is also one of the most affordable insulation options. However, it can be difficult to install in tight spaces and can irritate the skin and lungs if not handled properly.

Pros:

  • Easy to install
  • Affordable
  • Effective at reducing heat loss/gain

Cons:

  • Difficult to install in tight spaces
  • Can irritate skin and lungs
  • Not the most effective insulation option

Blown-in Fiberglass Insulation

Blown-in fiberglass insulation is another popular option. It is made of tiny glass fibers that are blown into the attic with a machine. It is easy to install and can be blown into tight spaces. It is also a good option for homeowners with allergies or sensitivities since it doesn't contain formaldehyde or other harmful chemicals. However, it can settle over time and lose its effectiveness.

Pros:

  • Easy to install
  • Can be blown into tight spaces
  • Doesn't contain formaldehyde or other harmful chemicals

Cons:

  • Can settle over time and lose its effectiveness
  • More expensive than fiberglass batt insulation
  • Can be difficult to remove

Blown-in Cellulose Insulation

Blown-in cellulose insulation is made of recycled paper products and is blown into the attic with a machine. It is an eco-friendly option and can be more effective than fiberglass insulation. However, it can be more expensive and can settle over time.

Pros:

  • Eco-friendly
  • Effective at reducing heat loss/gain
  • Can be blown into tight spaces

Cons:

  • More expensive than fiberglass insulation
  • Can settle over time and lose its effectiveness
  • Can be difficult to remove

Spray Foam Insulation

Spray foam insulation is a high-performance insulation option that is installed by spraying a liquid foam into the attic. It expands to fill all gaps and crevices, providing a seamless barrier against heat loss/gain. It is also an effective air barrier, reducing drafts and air leaks. However, it can be expensive and difficult to install, and it can emit harmful chemicals during installation.

Pros:

  • Effective at reducing heat loss/gain and air leaks
  • Provides a seamless barrier
  • Durable and long-lasting

Cons:

  • Expensive
  • Difficult to install
  • Can emit harmful chemicals during installation


Rigid Foam Insulation

Rigid foam insulation is a type of insulation that comes in large, rigid panels. It is effective at reducing heat loss/gain and can be used in a variety of applications. However, it can be difficult to install, and it is more expensive than other insulation options.

Pros:

  • Effective at reducing heat loss/gain
  • Can be used in a variety of applications
  • Can provide an effective air barrier

Cons:

  • More expensive than other insulation options
  • Difficult to install
  • Can be difficult to remove


Radiant Barrier

A radiant barrier is a type of insulation that reflects heat away from the attic. It is installed on the underside of the roof and is often used in warmer climates. However, it is not effective at reducing heat loss/gain and should be used in conjunction with other insulation options.

Pros:

  • Effective at reflecting heat away from the attic
  • Can be installed without removing existing insulation
  • Relatively inexpensive

Cons:

  • Not effective at reducing heat loss/gain
  • Should be used in conjunction with other insulation options
  • Can be difficult to install in some cases

Natural wool insulation is made of sheep's wool and is a natural, eco-friendly option. It is effective at reducing heat loss/gain and can be a good option for homeowners with allergies or sensitivities. However, it can be more expensive than other insulation options.
