Actually TS i would go with aluminum, its more expensive but its lightweight and cannot rust

This is definately a good idea, because sunlight will always prevent moisture from over gathering in a certain area but thing is most of us work during the day so we don't really open our windows more than we should to prevent over moisture

Why the sudden love with click vinyl? Any particular reason for this?

Corrects it just a way to make things look and feel nicer

I actually had some mould problem in my master bedroom and i gave the HCL89 from http://hcl89.byethost10.com a try as it seems to give the best promise to get rid of the mould from what i read around and after i had used the HCL89 about a year back the mould in my master bedroom has completely disappeared and has never appeared again Its a product worth the try because for me it got rid of my mould issue permanently and it would probably help as it did for me as well
