Vinyl frames or vinyl cladding may be affected by solar radiation or chemicals that can cause color change. The chart below shows color change when exposed to the Arizona environment.
Frame Color Change
- Chemicals can cause PVC discoloration. All fuels, solvents, bleaches or corrosive chemicals must be avoided.
- In dry climates with high levels of solar energy, a color change can be expected with PVC, like most any finish.
- A color change has no effect on the strength or structural integrity of the PVC.
- Over time and with exposure to normal humidity, this yellowing most often returns to a white color.
The chart below shows the evolution through the change process with a return to the whiter color after continuing exposure.
