Thank goodness for B&Q's no quibble refund policy. I had bought a
polycarbonate glazing pack (a green colored pack). It's one of those
packs that you can't open and look inside until you get it home and
then you discover it's a £80 pig in a poke. I bought an 8 x 6 foot
greenhouse from B&Q about five years ago and the polycarbonate pack I
bought was for an 8 x 6, but the panels were not wide enough and there
wasn't enough to glaze the whole greenhouse. It also said on the
side of the pack "base included", but there was nothing resembling a
base in the pack, just a load of polycarbonate panels so thin that
they resembled plastic cake boxes more than greenhouse glazing. I
tried fitting a few of the panels and needed at least double the
amount of clips I would use for glass, that's if you don't want the
panels to become airborne. You don't get any glazing clips with this
pack either.
