Hello!
As the title suggests – can there be advantages to choosing double glazing instead of triple glazing?
I read on Konrad Fischer’s website that while double glazing does not reduce heat loss from inside to outside as effectively, it does allow more heat to enter from the sun outside to inside. In other words, it creates a greenhouse effect, and in terms of overall energy balance, it might not be as disadvantageous compared to triple glazing as one might initially assume…
Furthermore, I’m interested to know if triple glazing can also have hidden but significant disadvantages.
In the case of renovating older buildings, problems can arise if the rest of the house remains poorly insulated.

I find his theories at least interesting and worthy of discussion.

I could imagine that it also depends heavily on the size of the window areas… In my new build, one side of the living room, which is about 70sqm (750 sq ft), is almost entirely glazed… In this case, I would try to make the thermal performance of the glazed areas as similar to that of the walls as possible. This is not achievable without triple glazing. Besides, in a reasonably well-insulated new build, you will want to shade rather than let in too much sun starting from the warm spring days. Also, on the coldest winter days, the rooms feel more comfortable if the inner surfaces of the windows do not have low temperatures.

but this also allows heat from the sun to pass from outside to inside more easily.And do you really want that? Do you have any idea how hot windows can get when the sun shines on them? Like radiators! Do you want to run radiators in summer? No? Then install triple glazing. It is better for both summer and winter. In winter, when you actually need it, the sun usually doesn’t shine due to weather conditions, or only at a low angle between 11 a.m. and 2 p.m. The heat gain is accounted for in the energy calculation—don’t worry—but it is insignificant compared to the overall energy balance.
Also, the argument about poor insulation standards in the rest of the house is questionable. Windows are usually the weak point. Even old walls and ceilings often have better U-values than new triple-glazed windows.
