I was given a good tip when insulating greenhouses without the groove for the plastic clip. I have an old Alitex greenhouse which has an ordinary frame the bars of which are T shaped and so there is no groove. I was told to put the insulation up and clip it to the extruding piece of the frame with butterfly clips. Places like Lidl sell large boxes of them very cheap and it works well and is cheap.
