i'm looking into making some cold frames/mini greenhouses using some polycarbonate sheeting
Does anyone know if you can drill holes in it (so i can fix it to a wooden frame using a screw a washer)
or would it crack?

Hi,
If you're talking about the flexible roofing sheets they should be fine to drill. I've done it in the past (and perspex too) I always start with a small drill bit maybe 2 or 3 mm in diameter just to get through it, then go back with another drill bit the size I need - just do it gently and not too fast.
Good luck ;D

i wouldn't say they are particularly flexible - it's the stuff that you can use to glaze greenhouses
so it's quite rigid
I'm sure you are ok to drill it, like you say, start with a small drill and work up - but just wanted confirmation that it wasn't one of those plastics that cracks if you try to drill it. I'm gonna go google!!!

You could heat a nail up over a camping gas stove,holding it with pliers,and then melt the holes needed. For the "glass" on our cold frame,we used an old shower screen thing that folds back on four sets of hinges.I still have two old sash windows to utilise when I get more wood for the frame bit......

yup, should be straightforward enough.
