• Another, seperate question on windows.

    We are getting some triple glazed units in, with EWI thereafter.

    Am I right in saying that the new windows should be installed as close to the current 'edge' as possible? That way the EWI can slightly overlap the window facing and improve thermal performance.

    We can get extended cills to account for this but will it expose the windows to more rain than usual, and is that a problem?

  • @gillies where are you getting your triple glazing from? You're Glasgow right? We're just on the hunt and the amount of sales people saying don't bother its not worth it (which I translate to: we can't source it / can't be bothered to source it with our current supplier) is astounding.

  • Glasgow yeah - almost certainly going with Nordan. I think the quotes we had from Rationel and one other (can't recall) were a good bit more expensive.

    The jump from alu clad timber double glaz to alu clad triple isn't really that much!

  • the bizarre thing is that the recent reg changes meant half the products available were not compliant, i’m amazed triple glazing wasn’t in the current regs pass group.

    this is what my go-to glazing firm told me last year ( SCI glazing in Morden) they did triple glazing at my old place and it wasn’t much of an upcharge over double, i specifically went for it as the surface temp of the inner pane was a fair bit higher than double and because the sofa was below a window I wanted to eliminate draughts cause by the rising air over a cold surface.

    the windows were Platinum NRG.
