Carpet pad is necessary for most residential applications, adding years of life to your carpet when using the correct pad. Carpet padding absorbs shock and provides a softer comfortable feel to your carpet.
Our general recommendation is to use a 7/16" 8 lb. rebond pad for residential cut-pile carpet, a 3/8" 8 lb. rebond for berber and a 1/4" 8 lb. rebond for commercial carpet. In many applications, it's best to glue commercial carpet directly to the floor.
