What plastic sheeting is..

Jun 17, 2012 15 Replies

The stuff used in greenhouses without eaves. ie the stuff is bent around a radius with plastic joiners to the edge of normal glass top and bottom. The old tatty instructions calls it plexiglass. Not any idea where you can get it and of course it needs to be cut to size. The current stuff is cracking on the bends after many years service, I suspect heat and cold and sun have made it go brittle.

Plexiglass is another name for Perspex

Presume it's pretty thin if it was supplied flat and bent in-situ? rather than heated and bent off-site and supplied that way.

Likely to be local suppliers dotted round everywhere, but here is an online supplier chosen more or less at random

price calculator reckons about £20 for a strip 2mm thick and 8 feet by 18 inches.

No. Perspex is a trade name belonging to ICI. "Plexiglass" is, I think, another trade name from across the Atlantic.

Your comment is like saying Electrolux or Dyson is another name for Hoover

acrylic aka perspex. Wickes sell 2mm

OK, Perspex and Plexiglass are both trade names for Polymethyl Methacrylate, happy now?

Well its not perspex, as its far bendier than that. It also from the description I was given, looks blue at the edges, not white and smells different when cut. Brian

Ah, I see, I did try a bit of similar thicknees perspex some years ago and it just broke, not enough flexability. Brian

Presumably one has to be careful to get UV stabilised stuff though, as I once had a polycarbonate box which I put some electronics in for out of doors use and it basically fell to bits in about two years, Went crumbly. Brian

Replaced mine from this company.

Go get some Makrolon at the right thickness you require. Indestructible and bendy too

Our new carport roof is polycarbonate - I sincerely hope it lasts more than two years! It's very flexible and tough.

I've had corrugated polycarb sheeting up for 14 years and it's still fine.

It's withstood all the weather can throw at it - prevailing very wet stormy westerlies at times, with the odd battering of hail. Only one slight thing I found - if a fastening comes loose, attend to it immediately; the flexing in the wind will eventually snap a bit off.

Makrolon is a trade name for solid, not twinwall, polycarbonate sheet.

Cheers Adam
