    So what caused him to suggest such an unusual gap size? Do you or Tom have a link to a document describing the windows?
  2.  
    I can email you the pdf unless I can upload it?
  3.  
    Russell once again:

    "Good afternoon Gareth,



    Thank you for your enquiry.



    Unfortunately upon review of your job we must decline due to our current workload."

    Currently awaiting pricing from:

    Nordan
    Velfac
    a few different SMART systems suppliers


    The Senior Architectural systems supplier said the smallest they can do in 2G is 28mm (4-20-4) and their 3G they can price in (4-16-4-16-4)

    I think we will go for a self install due to mounting in EWI envelope and I can ensure a bit more detail is spent on the fitment (and for my own enjoyment and satisfaction)

    The question - Powder coating in RAL9005 (black) on a South facing elevation - will it fade?

    I can see your private message Dave even tho it's correctly to Victorianeco , not the 'to myself' glitch.

    Doesn't surprise me Tom :cry: I won't be whispering anything truly private on here, that's for sure.

    Tom - why would you settle for 12 gap 3G? What is the benefit of the 3 panes? The data doesn't show much in terms of sound or insulation over and above narrower 2G or have I missed something?

    As I said above:
    Posted By: fostertomAlso to say that despite previous alerts about 16 being optimum gap, I generally do settle for 12 gap 3G, both with Russell's super-value range (they charge premium for basically the same window but 'PH grade' with 16 gap and double seals) and with Vrogum (with all-opening lights - I have no need of their fixed lights with 8 gap). Even with 12 gap 3G, at U1.1 they beat any aluminium window at U1.4 unless you spend more on exotic fill gas.
    That's the answer to 'why settle for ...' - for value for money with Russell, or for best-available traditional-style performance, with Vrogum. And
    Posted By: fostertomAlternative to 12 gap 3G, 16 gap 2G is prob almost as good, so I'll be doing that in future, for minimised embodied carbon, with either Russell or Vrogum.
    (note 16 gap, not sure about 20) confirms your last sentence. This is quite a climb-down from my 20yr (?) insistence on 3G, thanks to new insight in e.g. https://islandpress.org/books/build-beyond-zero#desc .
