A fiberglass pool can more than handle winter weather!
Extreme hot or cold weather is no match for fiberglass pools which is another reason they are the only kind we sell. They plow through tough as nails ever year without showing hardly any signs of age.
How? Because the material is outstanding structurally–so there’s less expansion and contractions than other pool materials proving they have amazing flexibility.
Also, the chemical makeup of fiberglass shows it is resilient and can withstand chemical cleaners and ultraviolet light. In a word– strong! Which is surprising because it is relatively lightweight–another plus.
As long as the plumbing is appropriately winterized you should have no surprises come spring when you open up your pool.
