A pool liner is a critical part of an above-ground pool. It is basically a large bag that keeps water from coming in direct contact with the pool wall. Installed properly, a liner can dramatically improve a pool’s performance and lifespan.
Since a swimming pool liner is designed to be impermeable, its primary function is to hold water in the pool. It also acts as a barrier to protect a pool from the elements. Without a liner, a pool may crack and leak from constant exposure to sunlight and the ravages of changing seasons.
A liner’s smooth surface protects pool walls from mold, dirt, and other matter, making the pool easier to clean.
Pool liners come in a variety of designs and patterns. Designs range from simple solid colors and whimsical underwater scenes, to elegant geometric patterns similar to those found on permanent, in-ground pools. Plain or decorative, liners give pools a refined, clean appearance.
Pool liners may be made of plastic or vinyl. Although plastic is much cheaper, vinyl is considered to be more resilient and more effective at keeping water in the pool. Synthetic vinyl is manufactured with ultraviolet inhibitors that slow down the damaging effects of prolonged amounts of direct sunlight.
Vinyl liners typically have an acrylic topcoat that resists fading caused by sunlight and pool chemicals. Liner strength and thickness usually range from the standard 20 gauge to the beefier 35 gauge. With normal use, quality vinyl liners last at least 10-15 years.
Liners for hard-sided above-ground pools come in three types and differ in the way they are attached to the pool sides.
1) Overlap pool liners
Overlap pool liners go over the top of the pool wall.
Non-corrosive plastic clips called “coping strips” are used to secure the liner before the top rail is re-installed.
Overlap liners are generally less expensive and easier to install than the other types of liners, but may have fewer color and style choices.
2) Beaded pool liners
These liners are installed on pools equipped with a track called a “bead receiver” located at the top of the pool.

These kinds of arguments, no matter how much they try to confuse you by being obtuse and arguing everything through insinuation, never work unless you buy the premise that men and women will not be with each other unless they're forced to.
