Padding for carpet costs between $0.25 to $1.50 per square foot depending on the type of padding.
The average cost for carpet padding with installation is $3.75 per square foot with labor and all materials included.
The padding material sells for an average of $1.50 per square foot.
Without a carpet pad, drafts and other cold air can seep through the carpeting, making the room feel colder.
A carpet pad helps block these drafts and adds an extra layer of needed insulation.
Most residential carpet requires a pad that is between 3/8 of an inch and 7/16 of inch thick with a minimum 6-pound density rating.
However, low-profile carpets, such as berber, should not use padding that is thicker than 7/16 of an inch (3/8 of an inch is commonly recommended).
Carpet padding is also called carpet underlay as it serves as the foundation where the carpets are installed.
The main purpose of carpet padding is to protect your carpeting.
The pad under the carpet keeps the underside of your carpet from wearing against the bare floor.
It also helps the impact of heavy furniture and foot traffic.
When choosing carpet padding think about its density and thickness.
The density of a carpet pad's foam is measured by pounds per cubic foot.
For good comfort and durability, experts recommend a foam in the 6 pound to 8 pound range.
The denser it is, the longer and better the pad will hold up.
Depending on the material, carpet padding can last up to 25 years.
Although, the most popular foam-based carpet padding only lasts around 10 years.
Over time, and especially in high-traffic areas, your padding can degrade and become misshapen and dirty, just like the carpet above it.
Lack of a carpet pad means less insulation.
Carpet is less durable without a carpet pad.
The carpet pad acts like a shock absorber and can greatly increase the life of a carpet.
When replacement is necessary, removal is more difficult than stretch in installations.
