Choosing Underlayment for Concrete Floors

Transforming a dull concrete subfloor into a cosy and stylish space is not an easy feat. However, with the right techniques and materials, you can achieve a comfortable and inviting atmosphere. If you’re considering carpet tiles as your flooring option, using an underlayment is essential to provide comfortable cushioning beneath your feet and also protect your flooring from moisture. In this article, we’ll delve into the significance of using underlayment for carpet tiles on concrete, and we’ll explore the various types of underlayment available in the market. So, buckle up and let’s get started on creating the perfect foundation for your new carpet tiles!

Why Use Underlayment?

When it comes to installing a new floor, there are many factors to consider, from the type of flooring material to the colour and design of the finished product. However, one crucial element that is often overlooked is underlayment. Despite its importance, underlayment is frequently disregarded or forgotten by homeowners and contractors alike. But why is underlayment so essential, and what are the benefits of including it in your flooring installation?
To begin with, underlayment – also known as underlay – is a thin layer of material that is installed between the subfloor and the flooring. Its primary function is to provide an additional layer of support and cushioning, improving the durability and longevity of the flooring material. When installing carpet tiles on a concrete surface, underlayment is particularly important for a few key reasons.
Firstly, underlayment provides a cushioned surface that helps to absorb impact and reduce noise. Without this additional layer of cushioning, the flooring material can be more susceptible to damage from heavy foot traffic or other impacts, and noise transmission between floors can be more pronounced.
Secondly, underlayment helps to protect the carpet tiles from moisture, which can cause them to deteriorate over time. Even if the concrete surface appears dry, there may still be some moisture present that can seep into the carpet fibers and cause them to mould or rot. Underlayment acts as a barrier, preventing moisture from reaching the carpet tiles and reducing the risk of damage.
But the benefits of underlayment don’t stop there. Depending on the type of underlayment you choose, it can also improve insulation and temperature regulation within your home. This can help to reduce energy costs and create a more comfortable living environment. And, of course, underlayment helps to create a smooth and level surface for the carpet tiles to be installed on. Without underlayment, even minor imperfections in the subfloor can cause unsightly bumps or lumps in the finished product, detracting from its overall aesthetic appeal.

Different Types of Underlayment

When it comes to underlayment there are several different types to choose from, each with their own unique advantages and disadvantages. By understanding the characteristics of each type of underlayment, you can make an informed decision and ensure that your flooring installation meets your specific needs and preferences.

Foam

One of the most common types of underlayment is foam underlayment. This lightweight and affordable option provides excellent cushioning and noise reduction, making it a popular choice for both residential and commercial applications. Foam underlayment is also easy to install, which can save time and money during the installation process. According to industry experts, foam underlayment can reduce impact noise by up to 20 decibels, making it a great choice for bedrooms, living rooms, and other spaces where noise reduction is a priority.

Rubber

Rubber underlayment is another popular option, especially for high-traffic areas or outdoor installations. This more durable option provides superior cushioning and impact resistance, which can help to extend the lifespan of your carpet tiles. Rubber underlayment is also resistant to moisture and mould, making it ideal for areas that may be prone to dampness or humidity. Some manufacturers even offer rubber underlayment made from recycled materials, making it an environmentally-friendly option for your flooring installation.

Felt

For commercial applications, felt underlayment is a popular choice. This dense and durable option provides excellent cushioning and noise reduction, even in high-traffic areas. According to a study by the Carpet and Rug Institute, felt underlayment can reduce impact noise by up to 50 decibels, making it an ideal choice for noisy environments like office buildings, hotels, and airports.

Cork

If sustainability is a priority for your flooring installation, cork underlayment is a great option to consider. Cork underlayment is made from renewable cork bark, making it an eco-friendly choice that also provides excellent cushioning and moisture resistance. Cork underlayment can be used in both above and below-grade installations, and its natural properties make it resistant to pests, mould, and mildew.

Choosing the Right Underlayment

Each type of underlayment has its own set of advantages and drawbacks. Here are some common drawbacks for each type of underlayment:

Foam Underlayment:

Limited durability: Foam underlayment is not as durable as other types of underlayment, which may result in it needing to be replaced more frequently.
Poor moisture resistance: Foam underlayment can deteriorate if exposed to moisture, making it unsuitable for areas with high humidity levels or water exposure.
Limited noise reduction: While foam underlayment does provide some noise reduction, it may not be sufficient for high-traffic areas or spaces where noise reduction is a top priority.

Rubber Underlayment:

Higher cost: Rubber underlayment is generally more expensive than foam or felt underlayment, making it less accessible for some budgets.
Heavy weight: Rubber underlayment can be heavy and difficult to install, requiring additional labour and time.
Limited aesthetic options: Rubber underlayment is typically only available in black or dark colours, which may not be suitable for all interior design schemes.

Felt Underlayment:

Limited moisture resistance: Felt underlayment can absorb moisture over time, making it unsuitable for areas with high humidity levels or water exposure.
May compress over time: Felt underlayment can compress over time, which can reduce its cushioning and noise reduction abilities.
Higher cost: Felt underlayment is generally more expensive than foam underlayment, making it less accessible for some budgets.

Cork Underlayment:

May discolour over time: Cork underlayment can discolour over time, which may affect its aesthetic appeal.
Limited durability: Cork underlayment is not as durable as rubber underlayment, which may result in it needing to be replaced more frequently.
Higher cost: Cork underlayment is generally more expensive than foam or felt underlayment, making it less accessible for some budgets.

Overall, it’s important to carefully consider the specific needs of your flooring project and weigh the advantages and drawbacks of each type of underlayment before making a decision.

Conclusion

So there you have it, not only does underlayment enhance the look and feel of your new flooring, but it also protects against moisture damage and reduces noise pollution. By evaluating factors like foot traffic, moisture potential, and aesthetics, you can select the perfect underlayment for your specific needs. With the right underlayment, you can enjoy a beautiful and comfortable floor that lasts for years to come.
