Attic Insulation Vs. Wall Insulation: What’s The Difference?

Insulation is an important element of home construction and maintenance that helps to regulate the temperature inside your home and reduce energy costs. Different types of insulation can be used in different parts of your home, including the attic and walls.

If you are considering insulation installation for your home, understanding the difference between attic insulation and wall insulation can help you decide which type best suits your home. This blog will explore the various attic and wall insulation types and how to choose the right one.


Attic insulation is the material that fills the area between the attic floor and the roof. It’s commonly constructed of fiberglass, cellulose, or foam and is used to keep the attic area warm in the winter and cool in the summer.


The following are some of the many options for attic insulation:

  • Loose-Fill: This type is made of small fibers blown into the attic space using special equipment. Loose-fill insulation is easy to install and can be added to existing insulation, but it is prone to settling over time and may require additional top-ups.
  • Batt:  This type of insulation is a pre-cut, pre-sized material placed between the attic floor joists. Batt insulation is easy to install but can be difficult to fit between odd-shaped spaces or around obstacles
  • Sprayed Foam: This insulation is a liquid sprayed onto the attic floor and expands to fill the space. Sprayed foam insulation is the most effective at sealing gaps and cracks, but it is the most expensive option and requires professional installation.


Wall insulation is the material used to insulate the space within the walls of your home.


There are several types of wall insulation to choose from, including:

  • Fiberglass: This is the most common type of wall insulation, made of small fibers that are either blown into the wall cavity or placed between the wall studs. Fiberglass insulation is the least expensive option, but it is prone to settling over time and may require additional top-ups.
  • Cellulose: This insulation is made of recycled paper and is typically blown into the wall cavity using special equipment. Cellulose insulation is more expensive than fiberglass but more effective at sealing gaps and cracks.
  • Foam: This insulation is a liquid sprayed into the wall cavity and expands to fill the space. Foam insulation is the most expensive option, but it is the most effective at sealing gaps and cracks and providing a continuous layer of insulation.

Attic insulation and wall insulation are both important for keeping your home comfortable and energy efficient. Several considerations—such as the local weather, the dimensions of the room you’ll be insulating, and your budget—will determine the sort of insulation you ultimately decide to use.
