When it comes to installing new vinyl flooring, there are many factors to consider. One of the most important decisions is what type of underlayment to use. Cork and foam are two of the most popular options, but what’s the difference between them and which one is better for your needs?
In this blog post by the Virgin Carpets and Flooring team, we’ll break down the pros and cons of foam back vs cork back vinyl flooring so you can make the best decision for your home or business.
When putting down vinyl flooring, it’s important to use an underlayment. This is a layer of material that goes between the floor and the vinyl, and it serves a few purposes.
As already noted, there are two main types of underlayment: foam and cork. Both have their pros and cons, so let’s take a look at each one in more detail.
Foam core backing is a popular underlayment choice for vinyl flooring, because it provides thermal insulation and acoustic isolation. Foam core is typically made from polyurethane, and it is available in both high and low density varieties. It is most commonly found in residential applications, as it is less expensive than cork and provides good thermal performance.
Foam core is a good choice for insulation because it is effective at stopping the flow of heat. It also has a high R-value, which means it can resist heat transfer very well. This makes foam core an excellent option for flooring in warm climates, or for buildings that are in need of energy efficiency.
Foam core is also a good choice for acoustic insulation which helps to reduce noise transmission between floors and rooms.
Foam core backing comes in two varieties: closed-cell foam and open-cell foam. Closed-cell foam has high density and is impermeable to moisture, making it a good choice for areas with high humidity or moisture exposure. Open-cell foam is less dense and more absorbent, making it a better choice for areas with low humidity or minimal moisture exposure.
Cork is a natural insulation material that is made from the bark of the cork oak tree. It has been used for centuries as an acoustic and thermal insulation, and it is a popular choice for flooring underlayment.
Cork is a good insulator because it is a poor conductor of heat. This makes it an effective option for both thermal and acoustic insulation. Cork also has a high R-value, making it one of the best insulating materials available.
Cork is also an effective sound absorber, which makes it a good choice for reducing noise transmission between floors and rooms.
So, which is the right underlayment option: foam or cork? The answer depends on your specific needs and preferences.
If you are looking for an affordable option, foam core backing would be a solid choice. It is also a good option for climates with extreme temperatures or noise exposure as a foam core backing offers thermal and acoustic insulation.
If you are looking for an environmentally friendly and sustainable material, cork is the better choice. Cork is also a fantastic sound absorber, making it a superior choice for reducing noise transmission between floors and rooms. However, cork is more expensive than foam core insulation, so that should be taken into consideration.
