The importance of underlay
The role of underlay is sometimes overlooked. Underlay improves underfoot comfort, absorbs crushing forces on the pile, overcomes minor imperfections in the floor and it improves the acoustic and thermal insulation properties of the carpeted floor.
There are three main types of underlay: felt, foam and rubber. Like carpet, all types are available in various grades and qualities and these can be matched to your carpet and the wear characteristics of your home. Ask your retailer about the options available.
An underlay should be firm but comfortable. Poorly specified underlay will lead to stretching and rucking and may result in a breakdown of the carpet backing. As a guide, if you stand on the underlay you should not be able to feel the floor with the heel of your shoe.
If you are replacing your carpet, don’t be tempted to use the existing underlay. It will have the same wear patterns that appear in your old carpet and these will quickly resurface in a new carpet. Carpet manufacturers’ warranties also require their products be installed over new underlay.
Ask your retailer about an appropriate underlay. You can also visit the following underlay manufacturers for information on their products:

Tip: A good carpet deserves a good underlay.
