I have to replace a couple of panes of glass in the roof of an aluminium greenhouse and I am convinced that there must be an alternative and better way to glaze a GH.
The problems are:-
1. Handling glass is dangerous, especially when working off a ladder resting against a structure made of glass
2. Strong thumbs and fingers needed to fit the metal D or wire clips that hold the glass in place
3. Gaps between the glass and the frame become homes to moss and debris which may lead to cracking - also harbours pests.
What I would like :-
1. to be able to reglaze without a ladder
2. easier fixings
3. no gaps between glass and frame.
Possible solutions:-
A. one pane of "glass" per panel, not two (but may need to be lighter in weight than standard or toughened glass - ? polycarbonate or similar)
B. to be able to slide the panels up into position from the ground - ?up a groove/channel
C. eliminate gaps with a ? capping bar that would fit over the roof frame struts and press down on the glass - again able to be slid up the struts after the glass is in position.
Ideally, these would be modifications to existing GHs and not need a new GH.
How would you redesign a GH?

I was looking at polycarb replacement panels somewhere a couple of weeks ago, but can I remember where 
Was an online greenhouse supplier if that's any use whatsoever?!
