Different Types of Carpet Underlay

The quality of a carpet is only as good as the backing or carpet underlay underneath it. The comfort, performance, acoustic properties, insulation, and wear resistance of your carpet are all influenced by the fibers and yarns that make up its backside and help it attach to the subfloor. An integrated carpet underlay is a good option if you want to get the most out of your carpet underlay and still save money.

PU Foam, Rubber, and Wool Felt are the three types of carpet underlays currently available on the market. With a general understanding of each kind of underlay, we have discussed the benefits and drawbacks below.

Type 01: Foam Underlay

Foam underlay is a relatively new product on the market that is intended to increase underfoot comfort. It is made from recycled sponges that are mulched before being compressed by steam into a large cylinder block. After that, it is carefully cut to a specified thickness of 7 to 12 millimeters.

  • Advantages of Foam Underlay Comfortable

They are underfoot, durable, and sound-absorbent Thermal Insulation Fitter- and environment-friendly.

  • Disadvantages of Foam Underlay

It is not recyclable.

Type 02: Rubber Underlay Probably

What do most carpets have under them? Products like PU Foam underlays and new wool underlays, which excel in all aspects, including comfort and insulation, are displacing rubber underlays. However, rubber manufacturers have improved by developing new flat textured sponge designs that resist compression and provide a more luxurious feel to your carpet. Traditional rubber underlays, on the other hand, had a waffle air gap design that compressed after a brief period.

  • Advantages of Rubber Underlay

Due to the density of the rubber, it has a firm underfoot feel and a high-impact noise reduction. It is hard to wear.


  • Disadvantages of Advantages of Rubber Underlay

It cannot be recycled, is unsuitable for installation, and has poor thermal insulation. Disadvantages of Advantages of Rubber Underlay Cannot be recycled, is unsuitable for installation, and has poor thermal insulation.

Type 03: Wool Felt Underlay

Due to their high thermal and comfort properties, wool-felt underlays are gaining popularity. The Jute/Hessian fibers used in traditional felt underlays were known to compress, resulting in neither thermal insulation nor luxury underfoot. However, “wool,” a superior fiber, has been sourced by some felt manufacturers. We all know that wool is a great insulator; it is used to make scarves, jackets, and blankets. Using wool as an underlay is a great way to keep the heat in your room.

  • Advantages of Wool Felt Underlay

High impact and airborne noise reduction, as well as very high thermal insulation, reduce heating costs. They also feel good underfoot and are better for the environment than rubber or PU foam underlays.

  • Disadvantages of Wool Felt Underlay Underfoot

It doesn’t feel as soft as PU Foam underlays.
