We have just received our first lot of WRC windows and doors for the new house we are owner-building from our window supplier and I realised that they have been double glazed with Argon rather than air!

We never specified argon filled DGUs and the window schedule always referred to an air gap. As far as I am aware, we were also only ever quoted based on air...
We have only received about a third of the windows so far (holding off on having the rest delivered until we need them) and the standard setup appears to be 5mm clear/12mm argon/5mm clear...we will have a couple of very large windows being glazed on site, which i think are something more like 10mm clear/14mm air/10.38mm low-e (comfort plus).
Does anyone have any advice as to whether I should point this out to the suppliers and/or whether I should be concerned at all about this?

Any advice would be appreciated!!
