Replacing T & Grouve on Conservatory and adding ventilation

[zikkimalambo]

Ok, first to set the scene........

"wooden" conservatory which is of a lean to shape, the box shaped bit is mostly large DG wooden framed doors , the roof is twinwall polycarb and the triangular panels which make the infill between the top of the glass box and the roof at the sides are wooden frame with T&G on either side.

The T&G is needing replacing and we'd like to add some ventilation. The conservatory gets very hot if it's left shut up, and the only way to provide ventilation at the moment is to open the doors. Not convenient when we're out.

Any suggestions for the best material to use on the outside, and what sort of ventilation to go for (or indeed if you think ventilation in these end panels isn't going to be effective).

More wood, seeing as you're going to have to periodically repaint the rest of the thing anyway.

A vent at the highest point will be effective provided there is a matching vent at low level (preferably diagonally opposite, to get a through flow of air). Even more effective if you put a small electric fan in it (solar powered)?

The message from [e-mail] contains these words:

Could you adapat a greenhouse thermostatic ventilator to your own frame and make a sort of top-hung window with wood instead of glass?

Something like this

each end of the conservatory. You could make it a long narrow slit if you're bothered about security.
