Vinyl siding is popular among homeowners. This is mainly because of its affordability, durability, and ability to protect a home from moisture infiltration. The question is: can it also improve the energy efficiency of a home?

Yes, vinyl siding is great at insulating homes because it is a poor conductor of heat. You can get an even better insulating effect by using insulated vinyl siding. This siding is thicker and comes with an added foam layer.

Here is what you should know about vinyl siding and its insulating effects.

Insulated vinyl siding tends to come in richer and darker colors than regular vinyl siding. This is because regular vinyl tends to be a little bit more vulnerable to direct sunlight and so manufacturers tend to produce them in less rich and darker colors in order to minimize the effects of direct sunlight.

As for insulated vinyl siding, it tends to enjoy the structural benefit of having contoured foam. It is less susceptible to the harmful effects of direct sunlight. As a result, manufacturers don’t have to worry about using richer and darker colors since they know that the siding has the added support of contoured foam.

Insulated vinyl siding also tends to create an appearance that is as close to real wood as possible. This is because the added support of contoured foam makes it possible for the sidings to create profiles that are sharper and way more crisper.

Energy savings

When it comes to energy efficiency, insulated vinyl siding is flat out better. This is because it contains an extra layer that enables it to provide additional insulation. As a result, it is better at reducing air conditioning costs, by up to over 14%, just because it is better at slowing the rate at which a home gains and loses heat from and to the external environment.


As far as installation is concerned, regular vinyl is easier to install than insulated vinyl. This is mainly because insulated vinyl is typically thicker, and this added thickness usually for an installer to go an extra mile.

The first thing that presents a challenge is cutting. Insulated vinyl isn’t as easy to cut as regular vinyl siding. As a result, in order to cut it properly, it is always advisable that you use a saw as opposed to hand snips.

The second challenge that you have to overcome is how the added thickness affects how the siding fits with the windows, trims, doors, and other in-wall accessories. As a result, you may have to use additional accessories in order to avoid an awkward-looking installation. This is a problem that you typically don’t face when installing regular vinyl siding.


Both types of sidings are incredibly durable and easy to maintain. And while vinyl-based siding had earlier created a reputation of being susceptible to warping, cracking, and fading, current vinyl-based products contain additives that enhance their ability to withstand direct sunlight and harsh environments.

However, there is a difference between the two types of vinyl when it comes to their ability to absorb physical impact. Insulated vinyl siding is better placed when it comes to resisting impact. This is because the added layer of foam that it has seals the gap that usually exists between vinyl siding and the wall. This is in addition to providing additional structural support.

The fact that insulated vinyl siding has an additional layer also presents manufacturers with the opportunity to make it more durable than regular vinyl siding.

For example, some manufacturers infuse the foam layer with insecticides. This helps prevent termite attacks, something that definitely goes a long way towards increasing the longevity of the siding. This is something that regular vinyl siding doesn’t enjoy.

Moisture management

Vinyl is a great material for siding because it is moisture resistant. This makes regular vinyl siding effective at protecting your home from moisture. However, since insulated vinyl siding usually contains a layer of foam, it is not as effective when it comes to moisture management. This is because the foam layer can trap moisture and this can create moisture problems like encouraging mold growth in vinyl siding.

A house wrap is recommended before installing insulated siding to make sure the issue does not spread indoors.

Can vinyl siding make my house more energy efficient?

Yes, vinyl can make your house more energy-efficient. This is because vinyl is a poor conductor of heat. Therefore, when you install it, you are effectively giving your house an additional coat of insulating material.

The added layer simply reduces the rate at which your home loses heat. It also slows down the rate at which it gains heat from the environment.

As a result, your air conditioning system doesn’t have to work as hard as it usually does in order to either cool or heat your home. It thus effectively makes your house more energy-efficient.

You can make it even more energy-efficient if you opt for insulated vinyl siding. This type of siding usually contains an additional foam layer that helps to enhance the siding’s insulating effect. In fact, research has shown that it can improve a home’s energy efficiency by up to 14.3%.

Does vinyl siding maintain dryness inside my house?

As a result, when it is properly installed, it will act as an effective moisture shield that will protect your house’s framing, framing, insulation, and other parts of the house, from moisture infiltration.
