How do artists address thermal contraction in PVC outdoor winter displays?
Artists creating outdoor winter displays with PVC face the challenge of thermal contraction, which can cause cracking or warping in cold temperatures. To combat this, they use flexible PVC formulations designed for low-temperature resilience. Techniques include incorporating expansion joints, selecting thicker PVC sheets, and avoiding rigid fasteners that restrict natural material movement. Proper installation spacing and UV-resistant coatings further enhance durability. By understanding PVC's thermal properties and applying these strategies, artists ensure their winter installations remain intact and visually striking throughout the season.
