    I've started a project of making greenhouse but being an amateur in DIY, I was looking for help on how to join the sheets together? Glue is not an option but is there some sort of "fitting strips" a bit like laminate flooring?
    if so please let me know!
    thank you

    You usually buy galzing bars for twinwall polycarbonate. How thick is the poly and where exactly are you doing the joins?

    Instead of a thick glazing bar you could use plastic H-section running a bead of glazing silicone along the section before you slide the poly into it. Proper glazing bars are better though.

    you will need intermediate support for the poly without proper bars at at least 2 points along the 2.5m length and maybe only 1 with proper bars but you need to consult the manufacturers requirements and off course the good advice from people here :D

    You need to make sure you use a silicone that is suitable for use with Polycarbonate, not all are.
    There is a product called fixall, which will stick and seal if you choose to go with the cheaper H section rather than a proper glazing bar.
