Part 2: Insulated Vinyl Siding 101 – The Advantages of Insulated Vinyl Siding

In the first part of this series, we defined what insulated vinyl siding is and established how it is better than regular vinyl siding. Now, let us take a closer look at its advantages and find more reasons why you should choose the product for your home if you want a worthy investment.

Increased Energy Efficiency and Comfort

No matter what the season or weather conditions, energy constantly enters and exits the home through a process called thermal bridging. This occurs when warm energy seeps through the traditional insulation installed in the walls, and transfers through the wooden studs. With insulated vinyl siding, however, your home gets an exterior buffer that prevents unwanted energy loss, which significantly reduces thermal bridging. This results in increased exterior wall R-value, which is the measurement of the resistance of a material or assembly against heat flow.

Aside from the added functionality, insulated vinyl siding also treats your home to cost savings. Reduced energy transfer means reduced utility bills, after all. Furthermore, the government promotes the importance of making more green choices, so homeowners who have insulated vinyl siding installed in their homes can enjoy tax credits simply for choosing a more energy-efficient option.

Better Sound Resistance

Insulated vinyl siding also helps reduce the level of outside noise that enters a home because of the additional foam backing. Lawnmower engines, passing cars, barking dogs, and anything else that can result in distraction or even loss of sleep should be the least of your worries.

Enhanced Impact Resistance

On its own, vinyl siding is known for being durable and virtually maintenance-free – and it only gets better with its reinforced insulated alternative. With the polystyrene foam backing that fills the hollow space between the siding and the walls and acts like a shock absorber against common impact sources, insulated vinyl siding is stronger, thus allowing for better resistance against hail, stones, and other similar sources of potential damage.

Improved Rigidity

The foam backing in insulated vinyl siding equips it with rigidity, which is especially helpful in  exterior renovation projects where uneven walls may pose an issue. The insulated vinyl siding’s rigid design emphasizes the lines, while hiding any imperfections. Moreover, due to its enhanced durability, insulated siding can be expected to maintain its straight and symmetrical shape for a long time.


Insects and other pests such as rodents love nesting inside walls. With the tough polystyrene backing that fills the gap between the walls and siding, these pests can no longer live behind the siding. Vinyl and polystyrene do not attract termites and other similarly destructive critters.

In the next and last installment in this series, we will answer the most commonly asked questions about insulated vinyl siding and give some additional tips that can help you maximize your investment.
