Hello
We are about to finalize a contract with a well-known construction management company. We are deciding between double-glazed or triple-glazed windows. Since we are considering window muntins (grilles), we were advised to choose double glazing because the muntins reduce the thermal performance (U-value) of triple glazing, and the extra cost for triple glazing is not financially worthwhile.
Do you have any tips, advice, or opinions?
Thank you

We are choosing RC 2 for the ground floor and RC 2 N for the upper floor, all triple glazing.In my opinion, that doesn’t make sense. The difference between these two classes lies only in the glass, not the frame. Usually, in a break-in, the glass is not attacked but pried open. In that case, both classes make no difference.

How much extra should the triple glazing cost?It’s standard, yes, but the price is adjusted if you only choose double glazing. Triple glazing with muntins makes no energetic sense (according to the building inspector), so the extra cost for the third pane is wasted. Or rather, I’m trying to find that out with this thread.
Continuous muntins function essentially as frame components. Aluminum profiles have an outer and inner shell with internal webs for decoupling. Incorporating muntins into this design is a complex and costly process. For vinyl (PVC), continuous muntins are a special construction, which also significantly drives up the price. With wood, the effort is somewhat less extensive. Where muntins are considered necessary for heritage or preservation reasons, they are applied on the exterior (but must be ordered as part of the package, not as DIY accessories).
With the installation depths required for triple glazing, muntins naturally appear quite bulky, which can quickly give a heavy, armored-glass impression. Triple glazing is typically at least two centimeters (about 0.8 inches) thicker than double glazing, which also affects the choice of sash and frame profiles.
The thermal insulation improvement of triple glazing does not come from having one and a half times more glass, but rather from having twice as much air space between the panes. Air provides insulation only where it is not replaced by something solid.
Forget about muntins, and forget about continuous muntins even more thoroughly. Instead, enjoy unobstructed views, much faster cleaning, and significantly lower costs. And choose triple glazing—not because double glazing is inadequate, but simply because double glazing is becoming the "future inferior standard."
If the cost of muntins is not offset by compromises in window quality, a 1 x 1 meter (3.3 x 3.3 feet) window will reach four figures in price. Around the total cost, that could pay for several vacations over the years just to accommodate muntins. Surely that can also be translated into shoes and handbags for one’s beloved spouse.
P.S.: All multi-pane glazing units require considerable force and make a lot of noise when broken. The time available to the intruder starts once they are detected. Therefore, prying is much more common. The protection against prying is the same whether you use frame profiles for triple or double glazing.

(I personally wouldn’t choose muntins, but if they fit…?)

Bieber081524 Feb 2017 18:09Just like what feels like 90% of all houses today. None of them have divided light windows. Simply leave out the muntins. Then choose triple glazing, and if you want, add the warm edge spacer—it probably won’t make much of a price difference, but that way you get it done right from the start.
