Buying your ideal flooring can be an exciting experience. With pricing of $2 &#; $8 per sq ft, you want to make sure you install your flooring the correct way. Maybe you heard of horror stories of people installing laminate flooring and hear cracking sounds when walked on. What lies underneath the flooring can determine how the flooring will react and sound in your home.

The following 7 items should be considered in an underlayment when you are installing your new flooring.
1. Compression &#; Provides Support and Impact Resistance
Underlayment compression is a key factor as heavy traffic areas can cause enough weight to &#;compress&#; your underlayment over time. So support can be temporary. So how do underlayments past testing for compression? By compression set testing.
Compression set testing is used to determine the ability of elastomeric materials to maintain elastic properties after prolonged compressive stress. The test measures the somewhat permanent deformation of the specimen after it has been exposed to compressive stress for a set time period.
The underlayment height is measured before the test. A clamp is held down for 12 hours on the underlayment and released. After waiting for another 22 hours, the measured height of the underlayment is taken.
Compression Set Test Results
- Fiber/Felt Underlayment &#; QuietWalk rebounded 78% of its height
- Foam Underlayment &#; 59% rebounded
- Fanfold Underlayment &#; No Rebound At All
During installation, knee pads or work shoes sometimes crush the underlayment and not rebound back. Making a drum sound when walking on the floor after installation.
Depending on the material the underlayment determines how much support is given.
Foam Underlayment
Consist of trapped air. If you can squeeze the underlayment and hear popping noise, then air is being released. Sometimes, you can hear the pop due to high traffic or appliances being rolled over the flooring. Once the air is crushed, it is gone.
Fiber Underlayment
Consist of recycled material, the underlayment is densier in material. No trapped air that won&#;t be released. Fiber/felt underlayment offers superior compression and sound absorption.
2. Moisture Protection
One of the other main benefits of using underlayment is moisture protection. Keeping your flooring from getting wet and stop from warping. Some underlayment consist of a vapor barrier built in.
Most products have the moisture vapor barrier facing down. This essentially allows the pooling/vapors to be trapped below the vapor. With our underlayment &#; our vapor barrier is facing up, and installing the fiber ½&#; to 1&#; from the wall. This creates a gutter system to allow the moisture to evaporate around the perimeter of the room.
So when a pipe leaks such as a washing machine, fibers will pull moisture in and away from the floor. This allows the floor to manage the moisture instead of blocking the water. This distributes the water out evenly.
3. Sound Absorption &#; Buffers Ambient and Impact Sound
Our fibers are laid out a certain way to simulate small air gaps without limiting compression capabilities. Also the various amounts of recycled materials used provides inherited properties of sound absorption.
Sound Testing Assembly
The ratings you see from flooring underlayment manufacturers are based off of assembly testing. This means that some floor to ceiling test consist of open web truss floor to 6&#; concrete slab.
You can get your rating number by first knowing what your assembly is. If you know your assembly or close to it, you can find sound rating test matched with the underlayment you are choosing. Sometimes, you will not find the rating for your assembly due to various assembly types built. Each test cost thousands of dollars and getting each assembly would not make sense due to every variance of assembly.
Over 94% of recycled material is used in our fiber/felt underlayment. We are also SCS certified and Indoor Advantage Gold as a contributor to healthy indoor air quality. The highest award a company can get. No off gassing, no voc, no allergens which clears the way to be used in schools, governments and hospitals.
5. Ease of Installation
One of the main factors to consider is the ease of installation. Can you roll out the underlayment very easily? Or is it rolled backwards and consist of you unrolling the roll manually across the floor? With our fiber underlayments, we engineered the roll to be rolled across making it a time saving activity for flooring installers.
6. Insulation Value &#; Thermal Properties
Our recycled materials come from used garments which have some insulation ratings. Mixed with various materials, we can achieve higher thermal ratings compared to one material such as foam.
7. Smooths out minor subfloor imperfections
Roughly 1/8th inch thickness and the density of the fibers are perfect to absorb small pebbles that protrude from slightly rough concrete finish or slight variance of OSB or plywood joints. Provides nice smooth installation.

Flooring underlays are something we don&#;t hear much about but they play a big role in making some flooring types more durable and comfortable. They&#;re actually a fundamental element that creates a layer between the subfloor and the flooring.
Some of the most common types of flooring, like carpet, hardwood, vinyl, and laminate, are enhanced in different ways when combined with the right floor underlayment.
In this article, we&#;ll introduce different types of flooring underlays, discuss their benefits and importance, and guide you in choosing the right underlayment for your place.

Why Use Flooring Underlays?
In many cases, using the right type of underlay for the flooring can enhance its performance and improve it in different ways. However, they&#;re not used for all types of flooring. Usually, we have underlayment for
- solid hardwood and engineered wood flooring,
- laminate flooring,
- carpet,
- and vinyl flooring.
We can also see it used under concrete and tiles. But regardless of the type of flooring, underlays can benefit them by
- Making the Floor More Comfortable
The underlayment offers support and cushioning making it feel more comfortable under the feet. This is particularly beneficial for those who have to stand long hours. This extra comfort reduces the stress and strain on the muscles and joints.
- Protecting the Floor and the Subfloor
As flooring underlay adds an extra layer between the flooring and the subfloor, it protects both of them.
For example, in areas where moisture damage is common, a moisture-resistant underlayment can protect the flooring from warping, swelling, staining, mold, etc. This is one of the main reasons for using underlayment for hardwood floors.
On the contrary, if water damages the flooring, the underlay stops it from reaching the subfloor leading to bigger headaches.
Except for moisture, it also protects the floor from impact (the underlayment helps in distributing weight more evenly), little problems and irregularities of the subfloor, changes in the temperature and humidity, and everyday wear and tear.
Therefore, the lifespan and performance of your floor and subfloor are improved. This is a great option for basements, bathrooms, and other places prone to impact, high humidity, temperature fluctuations, and moisture damage.

- Providing Noise and Thermal Insulation
Another great benefit of flooring underlays is reducing the transmission of sound and heat. So, they make the place quieter by lowering the levels of noise between floors, for example, footsteps or noise caused by dropping something.
Also, during winter and summer, they don&#;t allow heat to be transferred through the floor easily. The result is energy efficiency by reducing the amount of energy used for cooling or heating.
As mentioned above, the floor underlayments cover the minor irregularities you can find in the subfloor, providing a more stable and even surface to install the flooring. In addition, some even offer built-in interlocking systems or adhesives that make the securing and installation of the flooring even easier.
Overall, underlays are here to make your floor more durable and comfortable. Plus, you can count on having a more peaceful environment, energy efficiency, and more stable flooring.
The Most Common Types of Flooring Underlays
Different types of flooring underlays are available in the market but here we only discuss six of them that are widely used.
Foam Underlayment: Affordable and Versatile
The most common and popular flooring underlayment is foam underlay. They&#;re not only budget-friendly but also useful for various applications.
- They can be used as underlayment for laminate flooring, engineered wood, carpet, etc.
- Foam underlayment offers some desirable properties, like moisture resistance, sound insulation, thermal insulation, comfort, and subfloor compensation (covering small irregularities).
- It is easy to cut and install foam underlays. Most of them even come with built-in adhesive or tape.
- Polyethylene foam is light and flexible.
- Polyurethane foam is dense and durable.
- Rebond foam or bonded foam underlay is made of recycled foam pieces and offers excellent cushioning, subfloor support, and durability. So, it&#;s a great choice for carpet.
- Cross-linked polyethylene foam underlayment or XLPE foam underlay is another type that is stronger and more durable. It also provides better insulation properties.
- Foam underlays are available in different thicknesses and densities.
Rubber Underlay: Soundproof and Durable
With their exceptional soundproofing properties and longevity, rubber underlays are ideal for commercial spaces and residential apartments where controlling noise levels is important. They also work great as carpet, laminate, and engineered wood underlayment.
These flooring underlays are usually made of natural rubber, synthetic elastomers, or recycled rubber. Among these, synthetic and recycled rubber underlayment is more affordable. Plus, as recycled materials are used in them, they&#;re consider an environmentally friendly option.
Overall, due to their excellent resilience and acoustic insulation properties, rubber underlays are great for high-traffic areas.
Felt Underlay: A Thermal Insulator That Offers Comfort
Felt underlays are mostly used under carpet flooring because
- they provide extra comfort and softness under the feet.
- their thermal insulation properties can somewhat improve energy efficiency.
- their sound absorption properties offer a quieter and more peaceful environment, especially for homes with kids.
Like rubber, felt underlayment is made of recycled fibers or synthetic materials which is an affordable choice. However, for more expensive carpeting, wool felt underlay is usually used. This type of felt is made of natural wool and offers better acoustic and thermal insulation as well as more comfort and cushioning.
Cork Underlay: A Sustainable Choice for Energy Efficiency
Another environmentally friendly option, cork underlay is usually made from the bark of cork oak trees. They&#;re an excellent choice for reducing energy consumption (because of cork&#;s insulation properties) and levels of noise. They also ensure the floor is comfortable and soft under your feet.
Cork underlayment is best compatible with floating floors, like laminate and engineered wood, but you can also use it with tiles and other types of flooring materials as well. Besides, it can compensate for the irregularities of the subfloor to some extent.
What&#;s more, for easier installation and customization, you can get a cork flooring underlay roll. These cork roll underlays also come in different thicknesses.
Plus, as cork naturally resists mold and mildew, you don&#;t have to worry about it.
Combination Underlay: A Blend of All the Features You&#;d Desire
As its name suggests, combination underlays combine different materials and underlays to enhance their properties. Some of the most common combinations include:
- Foam and felt combination underlayment for better cushioning, resilience, and sound absorption,
- Rubber and foam combination underlay to add the durability of rubber with the comfort of foam,
- Rubber and cork combination underlay to combine the natural properties of cork with the resilience of rubber,
- Fiber and rubber combination underlayment adds the stability of fiber to the strength of rubber,
- And, some flooring underlays (rubber, felt, cork, and foam) come with a built-in moisture-resistant or vapor barrier layer to protect the floor and subfloor from moisture damage.
Vapor Barrier Underlayment: Resist Moisture Damage
In places, like bathrooms, basements, and wherever humidity and vapor rise from the subfloor (for example, coastal areas), vapor barrier underlays can put your mind at ease.
The integrated plastic or foil sheet stops the moisture from penetrating into the flooring leading to extensive moisture damage. This is particularly useful for hardwood flooring.
All in all, using flooring underlays is not a luxury, they can be necessary in some places to protect the flooring materials from damage. Read the following section to find out how you can choose the best underlayment for your place.
