well 'azi' i would think a more expensive thicker piece you would be able to find at any local garden and pond supply store.The one i grabbed some from sold it in 10', 15' and 20' widths. i think for my 20' by 15 for the pond was 220$ canadian, but like i said i think it was a little to thick somewhere around 5mm "i think". you may want to check aout some local flat top roofers(commercial) in your area through the yellow pages and ask to see if you can buy a piece off them, i worked as a roofer one summer a few years ago, this is where you i or you might find pieces thinner and also wider, some of the pices we laid down were 100' wide and probable 2 or 3 mm in thinckness. i promise i will get some pics going soon, i have a camera i am just really busy right now with work.
