Flooring is usually the last thing done in a home renovation project. After choosing the color and pattern of the carpet, you still need to choose right padding.
Carpet padding can extend the life of the carpet because it provides support underneath and protects the fibers from excessive squeezing. In addition, it can also make the backing last longer, so the carpet can resist abrasion. The padding also makes walking on the carpet more comfortable.
Most padding provide some sound insulation and are a bit like insulating materials. It can prevent the heat from escaping in the winter, and can keep the air-conditioned air indoors in the summer.
