Good evening to you all.
My house has a conservatory which was already built when I bought it, but in the summer it's too hot to use and it's too cold in the winter. The roof is clear polycarb. I am thinking of changing this to a more heat-proof polycarb or fitting some roof blinds. This will probably cost £5-700, so I only want to do it if it works. Does anybody have any experience of either? I was also thinking of extending the heating to add a small rad in the conservatory. Ultimately I would like to remove the crappy sliding French doors between the house and conservatory to gain some usable space.
Thanks for any advice.

A conservatory will always be cold under certain conditions - possibly the only way to stop it would be triple glazing.

Excessive heat can be resolved with blinds - in principal you need to stop the sun coming in.

I'm tempted to rip it down and start again with a proper extension but it seems such a waste!

whatever you do it will always be a compromise - I have similar set up with polycarb roof, had vinyl put to inside to reduce glare that worked, that was £280 for a 4x4 conservatory. I have a single heater in there now and leave it on a timer to come on low on a morning - makes the room pretty usable

I had complete blackout blinds fitted on the roof and this made a huge difference. Before I had a split system heat/cool air conditioner, but the blinds are the most effective. Its fine now with a combination of both.

Only thing Id wish I'd done was fit under floor heating.

I'm going to stick some 2" thick celotex under the polycarb roof on mine for the winter. Should hold OK with a good double sided foam tape.

If it works well with no damp or condensation problems I'm thinking of cladding it with white UPVC in the new year.

If it works well I may do the same - would you not have to allow a slight bridge between the 2 to prevent the condensation in summer ?

Pedant mode...

Making the roof more solid will probably be a violation of planning rules. Not that it matters particularly & a there is a negligable chance of being punished! :-

Definition of a conservatory:According to the Department of the Environment, a conservatory is defined as "A building that has not less than seventy five percent of its roof area made of translucent material, and not less than fifty percent of its wall area made of glass

When we had one built we had blinds and an air con unit fitted that did cold and hot. The problem with the air con was it was fitted to the dwarf wall and didn't really cool particularly well...cold air falls and all that. As for heating in the winter it was very good. Thankfully the blinds did a pretty good job in summer anyway.

If I was doing it again I'd have blinds and aircon/heating with 2 outlets, 1 high for cooling and 1 low for heating. Problem is finding a high enough wall on a conservatory.

It will still let the light in, just not through to the room!

I can always state it's temporary, but in reality I doubt it will ever be an issue unless I sell.

Do you mean the insulation board stuff? Would you paint the bottom white to look 'pretty' or just leave it as it is?
I suppose cladding over the top could soon be removed when it comes to sell, especially if it was stuck on with silicone.

There are already some drapes hanging under the roof, so hopefully the insulation will be mostly hidden.

It is a big conservatory though, about 9m x 3.5m.

I have quite a big conservatory , 35 sq mtrs. We put drapes on the ceiling , roller blinds on the windows and I installed underfloor heating.
More useable for longer now but at extremes of temperature I would still say it can be uncomfortable.
Underfloor heating is great
