Maximum ambient temperatures for guttering

[billwoods]

Does anyone know what the maximum temperature is for use of plastic guttering?

I am considering using on a house in Spain where the ambient can reach 30 C plus with extensive sunshine (UV).

The local builder has recommended stainless steel or galvanised tin. Both will need painting and I would rather use plastic, eliminating painting.

Thanks,
billwoods

It wont melt, but it will creak non-stop and fade in no time

You will need to space the brackets at every 500mm too, its amazing how the gutter will expand and try to bulge out between the brackets.

The metal gutters can be powder coated so no painting required....
Actually common in south of France and Greece (where they can be bothered to put gutter)
