There are certain carpets that require unique pad usage. One of those is the woven carpet. These carpets must be installed over a extra heavy super dense fiber pad or , in some cases, a heavy flat frothed foam. This frothed foam also works well with radiant heated floors.
Also, If you have a carpet that is being used in a commercial installation, check to see if this type of carpet is available with its own self-attached backing. This backing is built by the mill to optimize the performance of its carpet.
