Attic Insulation: Faced Insulation Vs. Unfaced Insulation

Posted by Wattson on May 4, 2022
A few different types of attic insulation are on the market: faced and unfaced. Which one is best for you? That depends on a few factors, such as climate and the type of insulation you plan to use. Let’s talk about the differences between these two types of attic insulation and help you decide which one is right for your home.


Types of Attic Insulation

Attics are often one of the most challenging places to insulate. Not only is there limited space, but the temperature can fluctuate widely, making it hard to find insulation that will work in all seasons. However, a few insulation types are commonly used in attics.


Fiberglass Insulation (Batt Insulation or Loose Fill Insulation)

One is fiberglass batting, which is inexpensive and easy to install. However, it does not provide as much insulation as some other materials.

Fiberglass Batt Insulation

Fiberglass batt insulation is a key component of any effective home insulation system. Designed to be easily installed in hard-to-reach spaces, batt insulation provides excellent thermal and sound absorption properties. Made from man-made fibers such as glass, wool, or plastic, batt insulation can effectively insulate homes against extreme heat and cold and can block out unwanted noise from outside.

Fiberglass Loose-Fill Insulation

Fiberglass loose-fill insulation is a popular choice for homeowners who are looking to improve the energy efficiency of their homes. This type of insulation works by trapping air in small pockets, which helps to inhibit heat transfer. It’s also great at air sealing. This makes it an ideal material for insulating attics and other areas where access can be limited.

Unlike many other types of insulation, fiberglass loose fill is relatively easy to install, making it a cost-effective and convenient option for homeowners. If you choose to install loose-fill insulation, contact a professional for help.


Rigid Foam Insulation

Another option is rigid foam board, which can be cut to fit around obstacles and provides sound insulation in both hot and cold weather. Rigid foam board insulation is made from polystyrene or polyurethane. It is available in various thicknesses and sizes and can be used to insulate both walls and ceilings. Rigid foam board insulation is easy to install, and it provides an effective barrier against heat loss. It also does not settle over time and maintains its insulating properties for the life of the structure.


Spray Foam Insulation

Most homeowners are familiar with the traditional pink fiberglass insulation used in attics.

There is a new type of insulation on the market quickly gaining popularity: spray foam insulation. Spray foam insulation is made from a mixture of expanding polyurethane and isocyanate, which allows it to expand and fill any cracks or gaps in the attic space.

Spray foam insulation can be sprayed directly onto the attic floor joists and walls, providing a tight seal that prevents heat loss and air leaks. This makes it an ideal choice for homes with old or drafty attics.

Spray foam attic insulation provides superior energy efficiency and can help to lower monthly heating and cooling costs. It is not surprising that spray foam insulation is becoming the preferred choice for many homeowners.

No matter what type of insulation you choose, be sure to add a layer of the vapor barrier to prevent condensation from forming on the inside of the attic.


Tips When Installing Insulation To Your Attic

When it comes to reducing your energy usage, adding insulation to your attic can be one of the most effective and affordable steps. There are several important things to consider when adding insulation to your attic space:

  • The type of insulation you use, the thickness of the layer, and how well it is installed. For example, it is generally recommended that you choose a high-quality material like mineral wool or cellulose for maximum impact.
  • Try to install a thick layer of insulation to prevent heat loss. The Department of Energy recommends having between R-30 and R-60 worth of insulation in your attic.
  • Work with a qualified contractor who knows how to install insulation in your home correctly.
By following these tips and doing careful research before making any decisions about adding the proper attic insulation, you can ensure that you get the most bang for your buck when reducing your energy bills.


Faced Insulation

Faced insulation is a thermal insulation type with a vapor-resistant layer attached to one side. It is commonly used in attic spaces, as the vapor barrier helps to prevent moisture from condensing on the underside of the roof deck and ceiling joists. Faced insulation is available in both roll and batt form, and it can be made from various materials, including fiberglass, cellulose, and mineral wool insulation.

One advantage of faced insulation is that it is quick and easy to install. Another advantage is that the vapor barrier helps protect the insulation from moisture damage.

However, faced insulation has some disadvantages as well. One drawback is that it can be more expensive than unfaced insulation. Also, the vapor barrier can make it difficult to access the attic space for repairs or renovations.


Unfaced Insulation

One popular option for attic spaces is unfaced insulation. This type of insulation features no external vapor barrier, allowing it to breathe freely and avoid trapping condensation buildup within the attic. It is also typically less expensive than faced insulation, making it a good choice for homeowners on a budget.

However, unfaced insulation does have some drawbacks as well. Since it allows moisture to pass through freely, there is a risk of mold or mildew growth over time. Because it must be installed loosely to prevent localized condensation buildup, there is the potential for gaps or voids that will reduce its overall effectiveness as an insulator.

Choosing unfaced insulation requires careful consideration of both its pros and cons before deciding whether or not it is the right choice for your home.


Choosing the Right Insulation For Your Attic

There are many different options to choose from when it comes to insulation. Also, it’s important to consider whether you decide¬†on faced or unfaced insulation. In order to find the right material for your home’s attic, it is essential to consider several key factors.

  • One of the most important things to think about is attic insulation costs. While some insulating materials may be more affordable upfront, you need to consider their long-term costs and how they will affect your home’s energy efficiency over time.
  • You should also consider how well each material can help to reduce heat transfer between the attic and other parts of your house. This can be especially important in colder climates, where poor insulation could mean a lot of wasted energy and wasted money on heating bills.
  • Consider how much insulation you need. Some attics are larger than others and may be more challenging to access. The R-value of your insulation will be a determining factor in how well it retains heat and keeps your home comfortable.
  • Think about the material’s comfort level and level of sound absorption. Whether you are planning to spend time in your attic or not, noise reduction can be crucial for maintaining a comfortable living space overall.
  • Consider hiring a professional for the best attic insulation. A qualified contractor will know the ins and outs of proper insulation for a finished or unfinished attic and how to install it properly. They can help you decide what insulation material to choose, such as structural insulated panels or spray foam.
