Buying carpet underlay can be difficult as different underlays serve different purposes. This guide should help you to discover which type of carpet underlay will work best for you. 

Polyurethane Foam (PU) Underlay 

So why should I buy Polyurethane foam underlay?

You should buy a PU foam underlay if you are looking for a basic, all-round underlay.

Polyurethane foam is a cheap carpet underlay with surprising benefits. 

Polyurethane underlay is very common in the UK, with many carpet and flooring fitters recommending this product. This material is light and malleable, making it a dream to work with. 

The PU underlay is comprised of completely recycled materials. As well as this, the materials can be used yet again after its long life of carpet underlay. 

The obvious advantage of a PU carpet underlay would be that it is extremely comfortable underfoot. The soft underlay acts as a shock absorber for your feet, making your floor much more comfortable to walk on. 

Polyurethane foam is an extremely durable and hard-wearing material and can increase the life span of your carpet. As well as this, PU provides huge heat insulation benefits and helps to retain heat. This will reduce the heating costs of your property and can be used as a budget alternative to underfloor heating.

PU underlay also provides exceptional sound deadening qualities. This helps to reduce the sound of footsteps and knocking through the floors. 

Sponge Rubber Underlay 

Here are several reasons why you should buy sponge rubber underlay:

You should buy a sponge rubber underlay if you wish to combine an underlay with underfloor heating.

Sponge rubber underlays have been popular since the 1950s due to their superior feel underfoot. Sponge rubber underlays are also highly versatile and can be used to find solutions for many problems. 

The underlay is available in either a flat profile or a waffle profile. Each offering its advantages.

Sponge rubber underlays are renowned for being excellent sound insulators. Thicker sponge rubber underlays help to reduce both impact and airborne sounds. 

The sponge rubber underlay also acts as a great heat insulator. Unlike polyurethane underlays, the sponge rubber underlay can be used with underfloor heating. A thinner sponge rubber underlay with a low tog rating will allow the heat from underfloor heating to pass-through. This will allow your floor to be comfortable and heated. 

Crumb Rubber Underlay 

Here are some reasons why you should buy crumb rubber underlay:

You should buy a crumb rubber underlay if you are looking for an extremely durable and long-lasting underlay.
