Replacing a Yorkshire Light

yoocan · 15 Jul 2007

Hi,

I intend to replace an improvised Yorkshire light over a doorway. I've skethed what it might look like in section.

I plan to buy pre-rebated timber for the top and two sides, the bottom of the frame will be square in section so rainwater can spill over the beading. Does that seem reasonable?

I hope to join the wood square (just butt the wood up together) with woodscrews and glue, would that do the trick or does it require a more fancy joint?

Also (not quite woodwork):

What should I join the flashing to the wood with?
What should I bed/seal the glazing on?
Can anyone recommend a sealant for around the beading?

Thanks in advance!

I don't see how you are going to support the roof, brackets?

I think the problem you would have is that you're trapping the rainwater in all the joints of the beading and rebate, it would be easier to make a frame undersize and put a twin wall polycarbonate roofing sheet over hanging the frame all round apart from the wall side and use the Easy Fit Edge Bar

Then a drip bar on the front

I wonder if it might be less trouble to instal a ready-made Velux or similar?

Heres a picture of the offending light:

It sits on the brick work either side of the door, I think its currently screwed in place.

I like the idea of the polycarbonate and timber frame as it would be light weight and easy to install. However this may not be tough enough (are there any standards for a pitched glass roof) I was thinking of using 6mm clear toughened glass.

For the timber frame, once built should I treat it with Cuprinol clear - can this be undercoated and glossed as usual?

Also about trapping the water in the beading, I was going to use glazing silicone to bed the glass , then between glass and frame also on both exposed edges of the beading.

Thanks

Do you really need the extra light on top, if not, the best way would be a small tiles pitch roof

I would replace the rafters if needed and lay the glass on top of them using a gasket system .

That sort of thing .

In these northern latitudes having a glazed roof section like that can and does make a huge difference to how light (or gloomy) a room is
