Dear All,

I'm about to build a new car port to hide my 300D under for the winter. This bit will be on the side of the house - I then want to continue around the corner along the back of the house and I'm going to call this car port extension a veranda!

All in all I want to cover an area of about 50 square metres. Ideally if I could I would use hardened glass for the roof but from a building point of view (with difficult triangular shapes) it will be too difficult and expensive. So I thought why not use polycarbonate?

Polycarbonate is strong, light, quite cheap compared with toughened glass, and easy to work.

From reading stuff on the internet, however, the down side seems to be that it tends to creak in the wind and the thermal expansion can be pretty large - also causing creaking noises.

This is a bit subjective but does anyone know how noisy / irritating Polycarbonate sheeting is?
Has anyone ever sheltered under it in a rain storm?

For example - Is it as painful as trying to suck your left eye out with a vacuum cleaner - or is it like the dull throbbing complaining often heard on the end of a telephone? I don't know do you get what I'm getting at???

As usual any help or comments will be greatly appreciated.
