Winter UV exposure can still affect synthetic liners, though its impact is usually weaker than in summer because the sun sits lower in the sky and daylight hours are shorter. Even so, UV radiation continues to break down polymers over time, causing gradual fading and surface weakening if the liner lacks proper UV stabilization.
Snow cover can offer some protection by blocking direct sunlight, while reflective ice can increase exposure on uncovered sections. High-quality liners include additives that slow UV degradation, helping them maintain strength through winter. Regular visual checks for discoloration or surface chalking can help you spot early signs of weathering before it becomes a structural concern.
