The Truth About Liner Thickness
- Above ground pool liners are generally marketed and sold by
a thickness standard called gauge. Gauge is not a set number but is a
truly relative number and liner manufacturers that use this measurement
are allowed to determine which gauge they want to use for stating their
liners' thickness.
The truest measure of a pool liner is done using an
international standard of mil thickness. This is an absolute fixed
measuring system. Just like an inch is an inch, so to is mil thickness.
