3 Types of Pool Liners Explained in Detail

Pool liners are criticle for all above ground pools. They provide a leakproof barrier to contain the water inside the pool walls. This article will detail 2 main factors that will determine the quality of a pool liner: construction and key liner features.

Liner Construction:

Today, pool liners are made from some form of vinyl, simply because it is durable, easy to manufacture, and economically priced. Two types of vinyl that are used are recycled and virgin. Recycled vinyl tends to stretch out of shape easily and is generally thinner, which makes it much more vulnerable to cuts or punctures. Virgin vinyl is molded of thicker sheeting, allowing it to have a greater resistance to stretching, tearing, and puncturing, meaning it will last much longer without any problems.

Also, the seams on the liner have an intricate role in preventing leaks and liner failure. There are two types of seams on liners, which are traditional and overlap. Traditional seams are basically the same type of seam that you see on most clothing items, where two pieces are joined, sewing the edges together. While this process works excellent with clothing items, under constant pressure from thousands of gallons of water it can easily separate. Lapped seams overlap at the edge, allowing for a much stronger bond, and also minimizing any chances of leaks or separation.

Key Features:

OVERLAP LINERS are the lowest costing and most popular type of pool liner today. They are, however, severely limited in terms of the colours and patterns available. The are easy to install, and can be installed without using any tools or special equipment. However, once they are installed they are rather difficult to remove and replace.

BEADED LINERS sit in the middle when it comes to price and popularity. They offer easier removal and replacement, with no cutting needed. They also offer a wider range of colours and patterns, and connect easily to an adaptor on the outside edge of the pool.

UNIBEAD LINERS are the most versatile liners available today because of their ability to be used on a U/J hook application or beaded applications. They are also very easy to remove, because they can be removed without having to take off the top rail or decking of your pool, which can save you valuable time and frustration!
