Insulated vinyl siding features contoured foam inside of it, that provides support to the siding panel. This added support allows vinyl siding manufacturers to, not only make products in the dark-rich colors that previously struggled with extreme temperatures from the sun, but also in wider, flatter profiles than ever before.

FYI: The 'profile' is all of the details of each particular siding such as the width, style and grain.

The supportive foam also helps maintain sharp, crisp profile lines that best emulate the appearance of real wood. Is Insulated better than non-insulated?
Yes. Most definitely. In general, insulated vinyl siding is going to be more expensive than non-insulated vinyl siding simply because there is more material in the product, it is bulkier and therefore more expensive to ship, and it can require additional steps for installation. Insulated vinyl siding also comes in more premium colors and profiles to create a beautiful exterior, but that makes it more expensive to manufacture.
Luckily insulated and non-insulated vinyl siding are both the lowest maintenance siding products available on the market today, reducing their lifetime costs compared to other products.
While sidings like fiber cement and wood require regular scraping, painting, and caulking, vinyl siding only requires an occasional cleaning with a standard scrub brush, soap, and water from the house.
Insulated vinyl siding is the only product that can reduce utility bills through energy savings, reducing its total cost over time. And because it helps protect the home from impact damage.
it can reduce the number of repairs that must be done to the siding over time.
The foam insulation also helps level the wall under new siding. Homes settle and walls shift over time, creating imperfections that can be seen through thin siding products. By adding a cushioning layer of insulation, insulated vinyl siding can help eliminate the appearance of imperfect walls.
Finally, contoured foam insulation helps protect insulated vinyl siding from impact damage. Traditional, non-insulated vinyl siding creates a hollow void between the siding and the wall, leaving the panel susceptible to impact damage from baseballs, rocks thrown from lawnmowers, or other projectiles.
By significantly increasing impact resistance, insulated vinyl siding will protect a home from damage and maintain the beautiful like-new appearance for many years. Energy Savings & Comfort: It’s safe to assume that an insulated vinyl siding product is going to provide more energy savings over time than vinyl siding without any insulation.
In fact, third party studies show that an existing 2-story home without cavity insulation can reduce heating and cooling costs by an average of 14.2% by adding insulated vinyl siding. Even if you have pink insulation in your walls, you are still losing energy through a process called thermal bridging.
The U.S. Department of Energy recommends insulation to be installed on the outside of a home when new siding is installed. Aside from monetary savings, you can also improve the comfort level of a home by adding insulation to new siding. Are there rooms in your home that are too cold to enjoy in the winter, or too hot and uncomfortable in the summer? Adding insulated siding is like wrapping the whole home in a blanket that helps keep heat inside in the winter, outside in the summer, and money in the bank all year.
If that weren’t enough, the foam component of insulated vinyl siding features a built-in insecticide which is safe for people and pets but protects the foam from termite damage. If your home has any termites burrowing into the foam looking for shelter, they will be killed by trying to bite the foam.
Just another layer of protection for the siding and your home. In conclusion, non-insulated siding has been the traditional choice for a lot of years, and the world has seen it thrive! But insulated siding is a major beneficial upgrade! The cost of insulated siding is about a 30% increase for material
