There are lots of different types of window dressing out there, from curtains to roman blinds, venetians to black out roller blinds. When it comes to sorting out something for your conservatory or orangery though, there are specific conservatory blinds available which will always be the best choice on the market.
Conservatory blinds are specifically designed and manufactured to be used in conservatories. By choosing the right ones you can make sure that you get the most use out of your glass extension in winter as well as summer. Roof blinds are long out of vogue, and well fitted blinds are now the best option for every home.
There are still a lot choices, so don't feel like you're being pigeon holed and you won't be able to get the blinds you're after, but when you're choosing conservatory blinds it's important to remember that you simply don't have the same freedom you would in a bedroom or kitchen. The windows are likely to be framed in plastic, and this will be the only available space to attach the blinds. Any mistakes will be costly.
Roller blinds in different sections around your room can be an excellent option, because you're given a lot of freedom with how they are positioned. They can be raised more or less in the summer to reduce glare and give you the shade you need to read or eat comfortably without being blinded. The shades will also allow you to better control the temperature, as the sun through the glass will be the main factor in warming the room.
The issue with variable roller blinds is that in the summer these are likely to be at a range of different heights to combat excess sunshine (well, we can hope so anyway), whereas in the winter months you'll want them fully closed for extra insulation and warmth. The sun is likely to cause the blinds to fade somewhat, so come winter you could end up with blinds with very strange fade marks across them.
Aluminium venetian blinds can look great in a conservatory, and give variable shade as well as privacy. You will be able to see through them as well, which means that you don't lose out on the benefits of sitting in a glass room, but you won't be sitting on display either.
Really, when it comes to conservatory blinds the choice is yours. Make sure you look specifically for perfect fit and other types of neat solutions designed just for this purpose, and your conservatory will be looking fantastic all year round.
