Does polycarbonate discolour in the sun?

Polycarbonate panels can withstand force and are virtually unbreakable. The excellent properties of polycarbonate panels make them the preferred material for building greenhouses. These panels are resistant to heat, sunlight, snow, and rain, which enable them to last for many years without fading or discolouring.

How long will polycarbonate stay clear?

Most Polycarbonates are made to last around ten years.
