Greenhouse blinds

Sounds very expensive to me. :blink:
Why do you want the blinds? is it to insulate or to reduce the amount of sunlight? If you want to insulate, a far cheaper way of doint it would be with "Bubble glazing" £72 would insulate a pretty big greenhouse! if you want to reduce the amount of light, you could use some paint-on-the-glass shading or throw some netting over the glass (that's what I do on very bright days)

JayG, I expect Dr Jim is thinking ahead to next season.

If you are looking for insulation because you are growing things, won't the blinds cut out light?
There's precious little of it in the winter anyway 

i think your rite Gwiz about shading i use netting on my greenhouses there a bit of a pain to put on because they tend to catch on the glazing strips

so ime thinking of putting the net on the inside not outside with those plastic clips that fit in the gazing bars because the UV rays seem to be getting stronger and soon burn the tender plants on the benches

we haven't had any problems using the nets and yes its less expensive
