Types of Insulation

Types of Insulation

Insulating your home is an important step in creating a comfortable living space, just ask the early pioneers who filled cracks in their log cabins with mud or paper. Today there are many types of insulation, and homeowners are not required to work with just what they can find on their own property.

Spray Foam

Liquid polyurethane, or spray foam insulation Maryland, can be applied by the homeowner or a professional depending on the grade you want. Because it’s sprayed on, it expands to fill crevasses in the wall or ceiling creating an efficient seal against the elements.


Another form of insulation that is recommended for tricky spaces, blown-in insulation, uses fiberglass and sometimes even recycled cardboard or newspapers to fill in the cracks. (The pioneers would be proud!) Like the spray foam, insulation that is blown-in can be a DIY project or completed by a professional.

Blanket Rolls

If you’re confident in your ability to complete the project yourself, consider blanket roll insulation. It’s easy to install and inexpensive. All you need is a utility knife to make it fit and protective gear to keep the fiberglass particles away from your skin and lungs. Most rolls fit standard-sized spaces.

Foam Panels

Foam panels take a little less skill to install and receive high energy efficiency ratings. They are mostly used to insulate unfinished walls and sometimes even floors.


Reflective barriers fight the good fight in especially hot climates. If you’ve ever seen someone put aluminum foil in the windows to reflect the sun, then you understand how this type of insulation works. Rather than creating a barrier to stop the heat, the reflective coating gives the sun its marching orders.

Each type of insulation has its advantages. Choose the one that best fits the parameters of your project.
