Water sealing strip for old conservatory windows

I am after a thin flexible plastic strip about 2" wide by 4 foot long which can be screwed of nailed to cover the gap between the wooden conservatory frame and two large sash windows.
On each vertical side of the sash and along the top to prevent rain from being driven in to this gap.

The water runs down the gap and pools at the bottom under the sash and stays there.

Half of this width of the strip would be fixed to the sash and the other half would cover the gap.

Hopefully this would prevent the water from getting in and over time rotting the cill.

This is an old wooden conservatory with no seals on the windows.

Any pointers as to what it is called and where to look for some please.

Looking from here ,Icant see much fall on cill (min10 degs) it looks like it will hold water,the detail at the end of the glass looks odd it probably not shooting over enough , a weather strip above the window on the frame would stop rain getting in the top and would help ,does the window have a weather groove this stops the rain being drawn in by capilary action and directs it down to the cill,

The guttering has been removed whilst I painted it, so that is not shown.

Your comments about the roof glass being too short has been made by someone else who came to advise a chippie on how to replace the rotten section ( in another thread).

He advised to add a bead of silicon on the under side of the roof glass about an inch in to prevent capillary action on the glass, so the absence of guttering and the glass being too short may all combine to make the water pool under the bottom of the sashes?

The slope on the cills was increased recently by a chippie with a plane but not under the sash, only the outer exposed part.

The window boards have the groove, they are on the bottom of the sashes.

It is a crap design though, no small windows at eye level.
Trying to do the best as it is.
