Installing quality carpet padding under your new carpet will help it last longer, feel softer, reduce noise and provide insulation.
While the cushiony comfort of your carpet may feel like the most important reason for choosing particular padding, keep in mind that specific pads are designed to help extend the life of certain types of carpet. The right pad absorbs the impact burden, relieving stress on carpet backing and fibers.
The Carpet and Rug Institute recommends a maximum thickness of 7/16” for cut pile residential carpet padding. The cushion under low-pile carpet, such as Berber or commercial carpet, should be 3/8” or less. When assessing quality, look for denser pad, rather than a thicker pad.
