Choosing the best carpet underlay can sometimes be challenging. It may need more profound knowledge and consideration that you might not be aware of. So, if you have decided to re-carpet your house or move to a new place and want it to be carpeted, you must first consider your underlay. We have some essential considerations that may help you to decide and buy the best carpet underlay for your home.

What Is Carpet Underlay?

Foam underlayment is usually used under broadloom carpets as a carpet underlay. Insulation, acoustics, support, and comfort are a few things it can be used for. 

Polyurethane foam, commonly used in furniture, mattresses, and car seats, is typically used as carpet underlay. You can extend the life of your carpet by using this foam. A thick underlay for carpet makes it a lot easier for the carpet to stay in one place instead of slipping.

Types of carpet underlay

Depending on the floor and room, carpet underlay is available in different types. In this carpet underlay guide, You can make an informed choice by knowing the difference between the different types of underlay:

Polyurethane or Foam Underlay

In an assortment of thicknesses and densities, this is one of the most versatile types of carpet underlay. In addition, it is straightforward to lay in challenging areas, such as staircases or hallways, since it is both soft and lightweight.

Felt Underlay 

The felt underlay provides excellent cushioning, noise reduction, and insulation, despite being more traditional. Due to their low cost and ease of installation, these underlays are typically made from wool. Wool felt underlay is an excellent choice for those who care about the environment

Crumb Rubber Underlay 

Heavy-duty carpet protection is provided by crumb rubber carpet underlay because it is dense and durable. It is ideal for all rooms in the home (including those prone to traffic, like hallways!) and for commercial buildings.

Crumb Rubber Combination

Underlay that combines felt comfort with rubber resilience is specifically designed for carpets and unsuitable for most other flooring types.

Rubber Sponge Underlay

You can use soft sponge rubber underlays in every house room, which come in a waffle or flat profile. Due to their ability to distribute heat evenly throughout a room, concrete floors and underfloor heating are often considered the best choice. Spongy though thick underlay for carpet provides a great surface to walk on.

Timbershield Underlay

Timbershield is a type of underlay for wooden floors. It is made of a very dense and heavy-duty synthetic rubber with a fleece backing. This underlay provides strong support to reduce flexing, even under heavy furniture. It is suitable for use with wood and laminate floors and helps to protect the floor and reduce impact and airborne noises.

Things to Consider


Most carpet padding measures between 6/16″ and 8/16″ in thickness (or 3/8″ and 1/2″). Overriding the range may result in installation problems.

Different carpet thickness requirements apply to cut piles and loop piles.

Medium pile carpets should be padded with 7/16″ or 8/16″ padding. Thick, dense pads provide structural support for carpets this cushiony.

Thinner carpet pads are best for low-pile or loop carpets. They should be at least 6/16″ thick. This carpet’s fibres crease and wrinkle due to more comprehensive, flexible pads.


The ideal carpet pad should weigh at least 6.5 pounds per cubic foot. Dense carpet pads generally weigh between 3 and 10 pounds per cubic foot.

It is usually recommended that you purchase carpet pads that weigh at least 8 pounds per cubic foot.

A good balance between cost and function can be achieved with materials between 6lbs and 10lbs, even though some materials can be exceptions.

The Room You’re Placing It In

Choose an underlay that will suit your needs based on whether you will be re-carpeting a room or re-carpeting stairs. In the former case, an underlay should be sound-proof and insulating, while in the latter case, an underlay should be flexible and easy to install on a complex surface.

Underlays should also be based on your home’s furnishings, as you do not want heavy items such as furniture to indent your carpet permanently. For this situation, thicker underlays like crumb rubber or smooth rubber are ideal.

To ensure your carpet and your home will last for years, it’s just as important to choose the suitable underlay for your home.

Tog Rating 

Carpet underlays should be chosen based on their tog ratings.

The composition, density, and thickness of the carpet underlay are considered to determine a carpet underlay rating. In addition, underlay is rated by its tog rating, which measures heat insulation. The tog rating tends to range between 1.0 and 4.0.

A lower tog is ideal if your home has underfloor heating, allowing warmth to radiate into your room through the underlay. A high tog may not be suitable for your home if you have underfloor heating. Underlay with a low tog rating is more likely to pass heat faster.

Be sure your underlay is resistant to high temperatures and can handle underfloor heating. If you don’t have underfloor heating, consider a tog of 2.5 or higher.


Choosing an underlay that will suit your needs depends on several factors, including the size and quality of your room or stairs and how much the carpeting stairs or room installation costs.

Budget your carpet underlay and stick to it. Then, decide how much you can afford to spend on it.

Keeping your costs low is possible if you install your underlay.
