    I've found there's no easy way. I've only had to cut some clear sheet when I replaced a section of the asbestos sheets on my garage.
    The corrugations "get in the way."
    I'd use a hacksaw blade or something similar and cut slowly by hand.
    Depending on the type of plastic, this can easily shatter if you use a power saw of any kind.

    If you're cutting in straight or gently curved lines, a normal rip saw just flies through them. You have to be careful though, because one stroke can get through several inches, so it is easy to drift off course.

    Be careful not to rip it though. I've found that to get the rythm started it is easier if curl the material such that the saw starts off kind of flat on the material as opposed to being at right angles with it. Once you get the rythm going it just zips through, but sometimes it will stick. When it does you risk tearing it slightly. You can reduce the risk of that happening by keeping the stuff loosely sandwiched between two planks of wood so if the saw does stick, it you don't end up lifting or pushing the sheeting too far with the saw.

    Thanks for the tips Cluelessas I wasn't sure how to go about it.

    I reckon I will buy the Bahco Prizecut toolbox saw from Screwfix at the supreme cost of £7.87 Reckons to cut both wood plus plastic, laminate and aluminium

    I used a hacksaw blade and it worked just fine - zips through easily and quickly, but be sure to support the sheet with a length of wood.

    Maybe the clear type is a bit more brittle. I managed, but it wasn't as easy as some have found it.

    You need to use a fine toothed blade and keep the angle of cut quite low. I'm fairly certain there is a general rule for calculating the TPI (teeth per inch) on a hacksaw for cutting materials of different thicknesses.

    I have found that a fine toothed tenon saw, kept at a low angle, with a piece of board below and a piece on top of the sheet works ok.
    Just dont rush it and let the weight of the saw do the work.
