Did a bit of surfing and came up with another solution.
the top pane of glass on the units is 65mm longer than the bottom pane
(and spacer bar) ...forming a drip. the bottom pane and spacer bar
then sit into a groove/rebate in the ring beam thereby holding the
unit in place preventing slippage.
how does that sound to you?
only problem I can forsee is that the spacer bar is exposed to UV.
this could be got round possibly by sticking on a flat covering
(plastic?) which would allow for water runoff

.. .
What are you using as a seal between the glass and the timber frame ?
EPDM - sealed unit - EPDM with hardwood capping screwed through to
the joists
What type of glass are you using?
4-10-4 hardened both sides
Are you aware that there are regulations in force, that actually specify
the type of glass used for this type of construction ? Do you know that
drainage of surface water also comes under regulation ? What type of
foundation is the structure standing on ?
Yes
Yes
Concrete Footings
Is the glass supporting any of
the weight of the structure or is the timber the only solid support with
the
glass being suspended from it ?
Glass sits on top of 6x3 joists.
Attached is a rough diagram of the problem area
Any ideas?

So the whole thing is supported on its own. Great.
If you're putting hardwood ridge timbers along the seams of the glass, then
a smear of sealant will act as a glue to hold the units in place and then
the ridge timbers cover the edges. You could fit small blocks of timber at
the bottoms of the joists to sit the corners of the glass against.
Alternatively, a length of quarter round timber along the horizontal support
with a squirt of sealant between will also keep the glass units in place.
The ridge timbers will then allow any surface water to flow off over the
top. Remember to allow for expansion on all the seams by using a flexible
sealant solution.
