How To Cut Polycarbonate Sheets, Cutting Twinwall Polycarbonate, Home D.I.Y

In this video I will be showing how to cut Polycarbonate twinwall sheets using a hand saw and electric jigsaw.

Tools required;
Hand saw that has a high tooth count,
Marker pen,
Tape measure,
Spirit level,
Electric Jigsaw,
Work mate or alternative support surface for cutting on,
Clamps,
Ear defenders and appropriate protective equipment,
Vapour barrier tape,
Scissors or sharp knife

Definitely remember the old saying ‘Measure twice cut once’, especially when using the jigsaw. Also, electric tools move faster so any mistakes happen faster too.

Position the sheets of polycarbonate flat onto the ‘work mate’ support bench so that the U.V protective layer / side is uppermost.
Get help, if required, to manoeuvre the polycarbonate sheets without damaging them.

Use a tape measure to carefully mark out the length required. Run the tape measure up each side of the polycarbonate sheet and place a mark to each side, using a marker pen.

Use a straight edge to link the marks from either side of the polycarbonate sheet and then use the marker pen to draw a straight line across the whole width of the sheet.

Using the hand saw carefully cut the polycarbonate sheet, starting on the side furthest away.

If required, get another person to help hold the sheet of polycarbonate as it is cut.

When cutting the polycarbonate sheet with an electric jigsaw use the same marking out process but make sure to cut away from you to prevent possible injury in case of accidental slips.

Once cut, make sure to clean the cut ends of the sheet and securely apply the vapour barrier tape. Cut the tape to length once it is placed on the polycarbonate sheet so as to make sure the tape is of a length that covers the whole of the cut end.

For clarity: I have no association or vested interest in the shop I purchased the polycarbonate from, which was ‪@RoofingMegastore‬
