Hot conservatory

We use ours as a second sitting room - radio,CDs etc - so don't like to leave the windows open when we go out and with heat reflecting blinds on the windows it gets up to nearly 50C! And it faces east so looses the sun mid afternoon. With a solid wall to the south and the house to the west we had thought it wouldn't get so hot.
(It's off the kitchen but a light tube should sort that.)

I agree with Mishap. Our 'conservatory' is upstairs and gets really warm but we just open windows and doors - I love it.

In winter it benefits from any sun there maybe and the rising hot air from downstairs. It it also incredibly light and brightens the whole house up. I love sitting up there when it's raining.

Sorry, not an answer to the OP but a reflection on how lovely a conservatory can be.

Suspect with solid roof it will still get very hot. When light passes through glass some of it is converted into heat. This escapes far more slowly than the light. It therefore builds up. You will still have a lot of glass.

I wonder if it would make the room from which the conservatory leads very dark as this is the effect my ceiling blinds have and they are a light colour and only really keep the glare out.

I love the heat in our conservatory - it is like soaking in a hot bath - bliss! If it gets too hot I open the doors and put on a fan - cheaper than roof blinds!

I'm thinking of having our conservatory roof replaced with a solid one. Do they need a planning permission does anyone know.

Mine is the same, NFkD. It is great for drying the washing on those days when you daren't hang it out for fear of showers, and getting any sun that is around in spring and autumn. Not so good for sitting out in through the summer and winte, even with a small portable convection heater which helps in winter, and a fan for roasting summer days. It is off the kitchen (only place it could go) o at Christmas it fills up with all the things that overflow from the fridge and need somewhere cold.

I have neither but with a S facing house would favour a solid roof as I could well imagine a conservatory would be as you describe! However I am sure it would earn its keep on a sunny but cold or windy i.e "normal" summer's day
