Triassic Posted September 21, 2018 Share Posted September 21, 2018 I’m thinking about flashing for use around my timber frame. I have a number of junctions between materials, things like a junction between some stone facing and a rendered section above, a junction between a rendered gable end and a slate roof and a junction between render and timber cladding. Is there any web sites that give details of how such flashings work and what materials are needed, as I need to get such things ordered. Link to comment Share on other sites More sharing options...
ToughButterCup Posted September 21, 2018 Share Posted September 21, 2018 I think advice on flashing might well be specific to the produce being 'flashed' as it were. The best I can do for you is to point to this site and suggest you follow some of the links. Link to comment Share on other sites More sharing options...
Triassic Posted September 21, 2018 Author Share Posted September 21, 2018 This was the sort of detail I had in mind, but specifically for flashing.... http://www.silvatecdesign.com/Technical Downloads/Silvatec Design Standard Details - September 09.pdf 1 Link to comment Share on other sites More sharing options...
Triassic Posted September 22, 2018 Author Share Posted September 22, 2018 (edited) I suppose the other thing I was wondering about, do you use lead for everything or are there modern alternatives? Edited September 22, 2018 by Triassic Link to comment Share on other sites More sharing options...
Cpd Posted September 22, 2018 Share Posted September 22, 2018 You can get pretty much anything made up out of plastic coated alloy, CladCo would be a first website that comes to mind. @pocster was using some flashings recently. Lead is supper expensive these days..... yes you can make use of it in really tricky spots but the modern equivalents are cheaper and look much more crisp.

Onoff Posted September 22, 2018 Share Posted September 22, 2018 I don't think you can beat lead for longevity, solidity etc. There's various alternatives some based on EPDM with a layer of aluminium I think. Bet the life expectancy is nowhere near that of lead. Of course lead has that "nickable" factor. Can't think of anything nicer that lead flashing with seam welded joints. Met a roofer years back on a Laings site. He was that good it was unreal. Known as "Ted The Lead". A dying art sadly...probably due to lead poisoning!

Yep - leads no good for me because I have to angle grind a slot . Will look nice and ‘sharp’ though . Photos when done . Link to comment Share on other sites More sharing options...

One of my roofer’s wanted to buy a 3m roll of 900mm code 4 just to finish an apex that was 200mm short in one corner... 10 minutes and one blowtorch later with my dads old lead soldering iron I’d put the corner on and you can’t see the join ... it’s not difficult to do, you just need to take your time - which is why most won’t do it as it gets put in the too hard box ... 2 Link to comment Share on other sites More sharing options...
vivienz Posted September 22, 2018 Share Posted September 22, 2018 I will check on the spec of the stuff my roofer is about to use. There's all sorts of stuff going up there, but I'm pretty sure that none of it is lead. Will get back with details tomorrow. Link to comment Share on other sites More sharing options...

I worked for a very large chemical company and we has a guy who specialised in manufacturing lead lined pipework, vessels and troughs, his lead work and welding was an art form in itself.

LA3222 Posted November 2, 2018 Share Posted November 2, 2018 @Triassic did you happen to find the solution to flashing the various areas where different finishes meet? I was pondering the same thing the other day as I have similar joins to sort out to those you describe above! Link to comment Share on other sites More sharing options...

I think someone here has used it. Lead, installed correctly, is fairly inexpensive and very long lasting. Link to comment Share on other sites More sharing options...

Good for flat surfaces but not malleable will only bend in one plane. It's two thin layers of aluminium sandwiching a layer of non-metallic mesh.
