Information for Specifiers

As part of our continued commitment to the design and specification world and support for our industry, this information is designed to make it easier to specify the right products for your projects.

We are delighted to now offer RIBA and BIID approved CPD’s as well as a range of products on NBS Plus, helping to make specifications as straight forward as possible.

The best way to make a decision about the specification of your underlay is to consider all the factors surrounding its use; the type of installation you require, whether you’re using carpet or hard flooring, the likely footfall, whether things like trolleys and baggage will be wheeled across the area, the desired level of comfort, acoustic considerations, and what fire ratings are required.

Specifying the Correct Underlay

We have many products that are made to suit specific purposes. To help find the one right for your project you can download our handbook or answer the few simple questions below to find the most suitable products for your needs.



Question 1 of (a Maximum of) 3

Is the underlay for domestic or commerical use?

The Importance of Underlay

Choosing the right underlay will make any floor

Look Better

Underlay protects a carpet and keeps it looking new by preventing the pile flattening.

Feel Better

Underlay delivers cushioning to make carpets so much more comfortable.

Last Longer

Underlay acts as a ‘shock absorber’ so carpets suffer less wear. New underlay can extend the lifetime of a carpet by up to 50%.

Helps To Reduce Noise

A carpeted floor with an underlay will act as a barrier to sound, ideal for multi-level living. Underlays for wood and laminate floors can reduce in-room noise by up to 30%.

Improves Hygiene

An underlay will also act as a barrier to embedded dirt, making it easier to clean and more hygienic.

Improves Your Insulation

Underlays provide an extra barrier to retain heat and could help cut your energy bills by up to 15%.

Provides Added Protection

Underlay will help to stop the carpet stretching and becoming loose, as well as providing a vapour barrier and preventing movement for wood and laminate flooring.

Reduce Uneven Floors

Underlay helps to flatten out uneven sub-floors.

Soundseal Technology

Designed to be buried within the sub-floor Decibel is a unique, noise reducing, application for underlay.

Already very popular in construction, Decibel products are
certified and extensively tested to European standards.

This new and innovative method can offer a saving both in cost and weight, whilst offering excellent acoustic benefits. It is a method that we envisage will continue to grow in the coming years both in the UK and across Europe.

As in many professions, carrying out regular CPD (Continuing Professional Development) training is essential to your development within your role as an Architect or Specifier. We have developed our RIBA and BIID approved CPD training to provide you with a solid basis for selecting the right underlay for your schemes and projects.

The training covers the types of underlay available, their relative attributes and also advice on choosing the right underlay for particular applications. Topics covered include sound reduction, flame retardancy, green credentials and all of the other benefits that come from selecting the right underlay. As well as refreshing your underlay knowledge we hope that you also leave with some new knowledge that you can apply to your everyday role.
