Does this stooled cill need a wooden cill too?

[SteWood]

Hi Folks

I'm creating a new window opening and have a hardwood window ready to fit along with a wet cast stone head and cill. I've tried to upload a photo to this site about 100 times bit it won't let me (so have just linked to an example on the web). So my question is this. Is it normal to have a wooden cill as well as a cast stone stooled cill or is it usually an either or situation?

Thanks
Steve

You don't specifically need a timber cill with stone as it depends on the design. With that type you will, else water will creep under the frame as the frame can't be set back above that solid portion along the back.

Finally I've managed to add a photo of my actual materials. Woody thanks although I'm not yet 100% sure what you mean. Could the frame not just sit centered and right back on the horizontal flat edge on the top/back end of the cill?

It did not look like the frame could be aligned with that upstand on the cill, as then it may be too far set back in the opening. If it can, then you wont need a cill.

OK well I'm building up the jambs to match the frame I have there. If it is too set back then I'll use the wooden cill. If not happy days..

Thanks

you normally have a stubbie cill as the window wont have a drip
