In most cases, you do not need to put padding or underlayment under carpet tiles. Unlike traditional carpet, which requires a separate pad, carpet tiles are designed to be installed directly onto a firm subfloor like plywood, concrete, or tile. Many carpet tiles come with a built-in underlay and attach with peel-and-stick adhesive, double-sided carpet tape, or glue. For a more comfortable, cushioned feel, especially in residential settings, you can opt for padded carpet tiles that have a thicker underlay attached. While it's generally not recommended to install a separate pad, a compact underlayment might be used in some situations, though this typically requires professional installation. An acoustic underlay may also be considered in commercial spaces or multi-level homes where noise reduction is a priority.

Carpet tiles are less expensive than traditional carpet. The average cost of carpet installation is $1,800, or $3 to $11 per square foot. In comparison, carpet tiles cost $2.50 to $11 apiece and can often be bought in bulk cartons. Since you can more easily DIY carpet tiles, you may be able to save on installation costs, too.

Stain-resistant carpet might be worth it for your household if you have children or pets and expect spills to happen. While it may cost more than you expected upfront, you may save money in the long run if you have to replace your carpet less frequently (thanks to stains not absorbing down into the fibers). 

The difference between a 40-oz. and 60-oz. carpet is the carpet face weight, meaning the 60-oz. carpet weighs 20 ounces more per square yard. When looking at two similar carpets of the same material and type, the 60-oz. carpet face weight likely indicates higher quality and more durability due to heavier carpet fibers.
