if you want a perm blind then look up corksol its a spray applied insualtion perfect for garden rooms

I would find a local blinds company and ask them if they can help, there are big firms out there but they tend to charge a lot of money compared to a local firm, where I live there are a couple that does made to measure at about a third of the big boys hope this helps Chris

Hi Hillary blinds
Or more expensive Thomas Sanderson blinds.
You would be better to Google a local blinds company near you they could offer a better more personal service and get them to quote.
Always look out for feedback from any conservatory blinds company.
Hope this helps

If you have a glass roof conservatory you can replace each glass pane for ones with integral blinds between the two sheets of glass on a double glazed unit
