Is there a need for this spec. Is it cost effective?

where will it end?

TBH i don't see many people buying it. Diminishing returns and all that.
Not to mention NOBODY HAS ANY MONEY!!!!!!!!!!:)

Define cost effective? Is this over 20years, in a house with say 40% heat loss through windows... Should we consider the benifits of glazing and natural light? And heat gain? Comfort and lack of cold radiant issues? Or do you just want to look at capital costs with a double glazed unit that is less than half the uvalue.
Personnally is be happy with thermally broken timber triple glazed units at in or around 1.0 overall u-value- bit their going to be pricier than the average upvc equivalent

As to where this will end, who knows, the technology will keep improving and the costs will come down with time.

Cost effective in relation to what is available right now, triple glazing. Maybe it might save 40% heat loss, but 40% of what number, put a context on this saving. If your starting point is a PHPP calc on a spread sheet in the planning stages then 40% of this figure is hard to save and I would doubt quadruple glazing is worth considering. Even if building to current building regs, I am not sure Quadruple glazing would offer serious savings over readily available triple glazing, even extrapolating savings/costings over 20 years, I still doubt the extra cost is worth it.

Maybe I am way off the mark here?

I think munster joinery should work on getting their existing products and installation right before launching uncessary stuff like this.

Too many stories of munster being relucatant to fix problems as it is.

I'd like to counter that with the experience I had with them recently. They've been very helpful in fixing any problems that we brought to their attention. Went with the triple glazed passive PVC window range with u-value of 0.8 (or 0.7 now apparently)

On the whole quad glazed thing, price is naturally a big factor but I'm a big fan of the comfort factor. You have to consider what a warm cozy room full of light worth to you.

Thats great to hear , hopefully they are upping there game, do a quick search of the forum though and you will see the unecessary misery they have put people through trying to get simple things fixed.

Fingers crossed they are copping on , as i believe the reason most people go with them is they are competitive price wise.

I'm going to counter that also. At least partially.
I raised a number of manufacturing issues with Munster Joinery and they've all been fixed. The Glazing had to be pulled from the frames to remove trapped paper pieces and also various of the restrainers had to be re-installed (those are the restrainers that prevent the window opening outwards by more than 100mm).

I'm waiting for them to come back to do some final works but so far so good with Munster Joiner.
