Conservatory and condensation!

royP_2

I have just had a new conservatory built and the last few mornings the roof and windows have been covered in condensation, any thought as to overcome this as we were hoping to use this space as an extra sitting room throughout the year?

The brochure did state that the conservatory increases living space etc, should I approach the builder?

Why should you approach the builder?

Its normal for condensation to form in an unventilated unheated room especially one with great expenses of glass

Open trickle vents if you have them or open windows a crack and get yourself some of those cheap dehumidifiers  you can get from a pound shop

If it's newly built then you may still be getting moisture coming from the building materials as concrete flooring and plastering fully dry out, I'd keep it well ventilated during the day and see if it improves.

But also have a look around for any signs of water leaks on the roof or where it meets the house, in case that's where the moisture is coming from.

Everything said above.

Plus, I presume there are doors betwixt the house and the connie? Do you by any chance leave these open overnight? If so, what's happening is that the warm air of the house - which is holding a lot of water in suspension - condenses out on the coldest surfaces it can find when the CH is turned off and the temp falls - and that will be inside your relatively poorly insulated connie. 

Even if you don't leave these doors open overnight, the connie will still be filled with that warm moist evening house air when nightime comes, and then it condenses out when it becomes cold.

Solution; when you are finished using the connie in the eve, shut it off completely from the house and crack open a couple of windows to 'trickle' in the connie, ideally on opposing sides.That will will almost certainly transform things. Of course, if it ain't sunny, your connie will be cold in the mornings. But, then again, connies are only ideal for use when they can heat themselves - they aren't intended for being heated as the running costs will be much higher than for any other room.

Try a dehumidifier our neighbour has one in their conservatory and reckons it is a big help to reduce condensation, they say it can need emptying every couple of days in damp weather.

There should be trickle vents on some of the windows so ensure these are open.  If the conservatory is very new it may simply be caused by the plaster etc drying.

Thanks all for the suggestions.
