ToughButterCup Posted November 6, 2019 Share Posted November 6, 2019 Along with @HerbJ here , I messed up on external window sill widths. So I need some. And since financial pips are squeaking, I thought I'd make some. How far either side of the window's structural opening should the sill extend?

Carrerahill Posted November 6, 2019 Share Posted November 6, 2019 (edited) Is this the external concrete/stone/metal ones or internal timber? Edited November 6, 2019 by Carrerahill Link to comment Share on other sites More sharing options...

Triassic Posted November 6, 2019 Share Posted November 6, 2019 (edited) In the cabin I used up offcuts 10mm thick slate floor tiles as cills. Edited November 6, 2019 by Triassic Link to comment Share on other sites More sharing options...

Interesting thought to use stone : how wide should the cill be - better put, how much wider than the structural opening should the cill be?

Construction Channel Posted November 6, 2019 Share Posted November 6, 2019 Whatever look right. Whats going on the reveals? (cladding/render) Don't forget whatever you put on the reveals will make the "horns" look longer. Link to comment Share on other sites More sharing options...

Some really nice bits of timber boarding - saved from the wooden packing which came with the windows: knot free, dead straight, stickered outside since delivery. Just needs a run through the thicknesser. And a good few coats of sealer. Really looking forward to it. Kiss the cat for me eh? Link to comment Share on other sites More sharing options...

About half the length of a facing brick. Edit: I can take a measurement off my neighbour's build tomorrow if you like?

Visti Posted November 6, 2019 Share Posted November 6, 2019 I've got about 35 alu cills going spare, 180mm deep... free to those in various lengths if desired. Didn't realize they had to extend past the external face by 25mm ? 1 Link to comment Share on other sites More sharing options...

Visti Posted November 6, 2019 Share Posted November 6, 2019 Truth be told, half the first batch of 21 were the wrong colour. Suppliers fault. Only after that did building control actually inspect and find them 10mm short... ? 1 Link to comment Share on other sites More sharing options...

Not sure that there is any reason for the cill to be any wider than the structural opening, other than aesthetic preference? I'll shortly be fitting aluminium pressings, and they'll be the width of the opening (minus a few mill for fitting and a bead of silicon) Link to comment Share on other sites More sharing options...

My guess. During heavy wind driven rain, water flows off glazing, over cill and then drips clear of wall. Without a 100mm extra each end some of the water flow will escape over the cill ends and run down the wall. 1 Link to comment Share on other sites More sharing options...
