Carpet Cushion

Carpet cushions, or carpet pads, serve as the base that helps carpet retain its texture and appearance and is crucial to carpet performance and longevity. Cushion is made primarily from polyurethane foam (including the very common bonded foam product referred to as "rebond"), fiber or rubber and comes in several styles and constructions.

In addition to enhancing the comfort and performance of your carpet, carpet pads can bring added bonuses. Moisture barrier carpet cushions can prevent spills from seeping into the cushion, inhibit the growth of mildew, provide sound insulation, and in some cases, extend the life of your carpet's warranty!

Choosing the right cushion is just as important as choosing the right carpet.

A proper cushion benefits carpet by:

Increasing comfort level
Extending carpet life
Absorbing impact
Reducing sound
Insulating rooms for better climate control
Helping carpet resist matting and crushing

Preliminary Cushion Check List:

Find out the carpet manufacturer's general requirements.
Carpet cushion is sold by its thickness and density. A cushion that is either too soft or too firm will adversely affect the performance of the carpet. A cushion that is too thick interferes with the anchoring of the carpet.

A heated floor system, also referred to as hydronic or "radiant-heated" floor, can be used under carpet.
You will need to check the thermal resistance rating (R-value) of both the carpet and padding. CRI notes that most floor systems manufacturers suggest a total maximum R-value for carpet and cushion not to exceed 4.0.

Learn your specific carpet type.
Carpets come in cut pile (including textured plush, Saxony, frieze', and velvet), cut-loop, level loop, and multi-level loop-or patterned-pile. Different constructions may have different cushion requirements. Check the manufacturer's recommendations for your particular carpet.
