Sun and heat
Ultraviolet rays fade fabric and plastic and make them brittle over the years, and high heat dries out wood so it cracks and softens some resins and plastics. The problem is worse on dark surfaces that absorb more heat.
Alternating strong heat by day with humidity at night also stresses joints, welds and cushions.
Effects of sun
- Fading colours and cracking plastic
- Dry, splitting wood
- Stiff, tearing fabric
- Dulling of glossy surfaces
