The liner in an above ground swimming pool is made of vinyl, and designed to hold the water in the swimming pool. The water inside the above ground pool gives the pool shape and holds up the above ground pool walls. If all of the water is drained from an above ground swimming pool the thin steel walls will collapse and may be damaged. Above ground swimming pool liners are a functional part of the swimming pool, but also add style and character. Above ground pool liners are available in an amazing selection of attractive patterns and styles, and often set the décor for the entire swimming pool area.

Replacement swimming pool liners for above ground swimming pools can be found in several different thicknesses. The thickness of the vinyl pool liner material indicates how durable the pool liner is, and how long it might last in a swimming pool. The thicker the pool liner material is, the more durable it will be. The pool liner included with most new above ground swimming pools is a plain blue color, in a 20 "mil" or 20 "gauge" thickness. Replacement above ground pool liners can be found in thickness up to 30 gauge.
Above ground swimming pools are built to accommodate either an overlap style liner, or a beaded style liner. The difference between a "beaded" style liner, and an "overlap" style liner is how the liner is held in place inside the pool. Beaded style above ground pool liners have a very small groove or lip at the top edge of the liner. This small lip is snapped into a track, which runs all the way around the inside of the swimming pool at the very top of the pool wall. This track holds the pool liner in place, and if your swimming pool requires a beaded pool liner you will be able to see the track if you look up under the top rail on the inside of the above ground swimming pool.
An overlap style liner is folded over the wall of the swimming pool, underneath the top rail of the above ground swimming pool. If your swimming pool requires an overlap style liner, you can see a small amount of the pool liner under the top rail on the outside of the pool. The top rail of the above ground pool is removed all the way around the pool to install an overlap style pool liner. The liner is placed inside the pool, and draped over the top of the thin metal wall of the pool. Long plastic clips are placed over the liner and the thin metal wall to hold the liner in place. The top rails are then installed on top of the new liner, and most of the excess liner hanging down on the outside of the pool can be trimmed off.
