Article How Cold Weather Affects Fiberglass Swimming Pools (Strong yet flexible, this material just may surprise you!) By Probuilt Staff January 31, 2023

If you reside in any part of the country where the temperatures have dropped so much this winter that your nose hairs freeze and you can’t feel your fingers and toes anymore, you may wonder if a fiberglass inground swimming pool can withstand such an extremely cold environment. Are fiberglass pools affected by cold weather? That is a very common question, and we think you might be pleasantly surprised by the answer.

If you are wondering if a fiberglass pool can handle bitterly cold conditions, worry no more. When you do enough research on the topic, you can put your mind at ease. Why? Because a fiberglass pool can handle harsh winter weather with ease and style.

Fiberglass: Hot or Cold, This Phenomenal Pool Material Can Withstand the Elements

No matter if it is extremely hot outside or bitterly cold, your fiberglass pool was made to handle it all. Given proper care and maintenance, which is minimal, a fiberglass pool can endure season after season. Why? Well, it all comes down to the materials with which they are constructed and how they are made:

  1. Fiberglass pools are structurally stable. As a result, they will display less contraction and expansion when exposed to extremes in temperatures, whether hot or cold.
  2. Fiberglass pools have chemical stability. Because fiberglass is chemically inert, it will not react with other substances. Even when exposed to pool cleaning products, UV light, and sanitizing products, fiberglass remains unfazed.
  3. Fiberglass pools have incredible strength. The high strength-to-weight ratio of these pools is what makes it so easy to move a fiberglass pool into place and is also why it is resistant to damage.
  4. Fiberglass pools have amazing flexibility. Despite how strong it is, a fiberglass pool is also quite flexible compared to other types of pool materials. As a result, while the soil surrounding the pool may contract, expand, and move as the ground thaws and freezes, a fiberglass pool can withstand the changing pressure. No worries about cracking!

Believe it or not, one of the best testing grounds to assess the resiliency of fiberglass pools in cold weather is in Canada. Famous for harsh winters, Canada has fiberglass pools spreading across the country, from one coast to the other. With properly winterized plumbing, pool owners there can be ready for swimming fun in the summer without fear of winter weather damage to their pools.

Wintertime is a great time to dive into some research on the topic. Once you discover all of the wonderful qualities of fiberglass, your next move is to discover all of the stunning designs from which to choose.
