Perspex Window Crazing (1 Viewer)

[Dave and Ginny]

Hi all

Only noticed this recently and it seems worse now than a few weeks ago. Rear window on our 2002 Hymer b544 has this odd crazing appearing. Mostly towards one side, on the outer laminate, but quite severe along the edge. It's just like little cracks in the perspex about 1/4 to 1/2 inch long.

The window appears simple enough to replace.

Anyone else had this or have any idea on the cost of a window and good supplier?

Cheers Dave

That crazing can be come from a couple of causes.
1. UV breakdown. Should not be a problem with decent quality materials, but will be an issue with acrylic that has poor UV protection.
2. Chemical attack. Take great care with the cleaning materials you use. Hydrocarbons / solvents are generally a no-no.

Once it happens, there is no "cure" except replacement.

Cheers,
Peter

Cheers Peter, I think it must just be age and UV as I don't use any nasties on it. Curiously the worst part is on the side directly above the fridge top vent, whether that could be a factor I don't know. They look easy enough to replace, just very expensive to buy!
