Do all greenhouses have a gutter?

[tweacle]

Hi there

I was given a greenhouse and im convenced that the gutter bit is the wrong way up but other people say it aint and their aint one. Can anyone help.

Its just I aint put the glass in yet and wanna get it sorted before that.

Apologies if in wrong forum. If it is could someone plse move to right one.

Thanks

difficult to say, to me it does seem that its the correct side up as there is a small seam where you put some rubber beading to bed the glass. However I could be totally wrong, my grandmothers greenhouse doesnt have a gutter on either side. Is there a makers name on it anywhere so you could check?
