The Benefits of Insulated Vinyl Siding

insulated vinyl siding

Today’s siding market has expanded from the traditional options like stone or wood. Nowadays, the most popular siding choice among homeowners is vinyl siding. What many homeowners don’t know is that there are two types: hollow vinyl siding and insulated vinyl siding. Here, we share some of the benefits of the insulated style.


Insulated vinyl siding is filled with a form-fitted polystyrene. This makes each siding piece more rigid than hollow vinyl siding pieces. When you attach insulated siding to your home, it creates a firmer, cleaner look than common flexible vinyl. Many homeowners prefer this look, as it gives their home smooth sightlines and a more solid appeal. In addition, as your home settles and walls shift over time, insulated siding won’t show their movement as much.

Because of its rigidity, insulated vinyl siding also boasts an added strength against natural elements. When a strong wind blows, hollow siding can rattle. And because it’s flexible, it can be damaged by debris like rocks, branches, and other projectiles. Insulated vinyl siding, on the other hand, stands up firmly to strong winds and can resist damage better than hollow siding.

Energy Efficiency

Standard home insulation helps form a barrier between the interior of your home and the outside elements; the insulation in vinyl siding does the same thing. When you choose insulated vinyl siding, you add an extra layer of protection to your home. This can help keep it warm in the winter and cool in the summer, reducing your energy use. By using less energy, you can save on your monthly heating/cooling bills. In addition, you and your family will stay comfortable through all of the seasons.

Moisture Protection

One of the most important elements that your home needs protection from is moisture; moisture can cause your home’s wooden structure to rot and warp. While vinyl siding is the best protection against moisture, insulated vinyl siding actually performs even better than hollow. In a Maryland study done by the NAHB Research Center, experts found that insulated siding performed best when it comes to drying capacity.


When you compare vinyl siding to other siding materials (like aluminum, stone, wood, and more), the installation process is relatively easy. This makes vinyl siding a cost-efficient choice. When it comes to insulated vinyl siding, the process is essentially the same as hollow siding, however, it may require a little more time and some different tools. Because of this, we recommend hiring a professional company like P.J. Fitzpatrick for your installation.
