ᐅ The Ideal Wall Construction for a Solid (Masonry) House

Hello everyone, I finally want to build on my plot and have shortlisted four homebuilders – but I’m struggling to decide because each has their own philosophy about the ideal wall construction.

Poroton brick, insulation, plaster, plus triple glazing
----------------------------------------------------------------
Probably a classic nowadays. The house is completely airtight. The walls cannot “breathe,” so moisture from inside the house cannot escape. A ventilation system is therefore mandatory.

Brick, mineral wool, air gap, brick facade, plus triple glazing
-----------------------------------------------------------------
Walls are somewhat more “breathable,” but the companies still recommend a ventilation system.

36.5 cm (14.4 inches) Wienerberger thermal brick, plaster, no additional insulation, plus double glazing
------------------------------------------------------------------------------------------------------
The “Mercedes” among bricks, no additional insulation needed, walls can breathe, triple glazing is not necessary.

So, which company is actually right and offers the perfect wall?

I have removed the names of the providers because otherwise I would have had to move the post into the moderated forum.

What is this, an advertisement?
Why are triple-glazed windows considered a bad thing? Who says they are the top of the line? People often jokingly call a particular type of brick a “biscuit,” too.
Why are ventilation systems seen as negative? A modern house shouldn’t breathe uncontrolled... that’s part of the point. Besides, the bricks are hardly permeable enough to allow the necessary air exchange on their own—otherwise, heating costs would be comparable to those of an old building.
Every option has its pros and cons; there are countless articles and forum posts about this...

Walls do not breathe...

All walls are perfect in their own way – the house is sealed and does not allow ventilation in any variant. Therefore, a controlled residential ventilation system is highly recommended.
Which wall you choose is your personal decision; you will live comfortably in any house.

If you want to build with a general contractor, then trust their construction methods. There are other factors that influence the decision of which building partner to choose.

In my personal opinion, you don’t have to know everything better; costs and quality in construction are much more important for laypersons and easier to evaluate.

We are also experimenting with the planning of our solid house. We definitely want to build solid and without insulation, unless there is cost-neutral insulation without polystyrene...
But well, that is actually questionable.

The healthier brick is Poroton (vapor-permeable), while the more affordable and easier to work with material is aerated concrete.

The difficult choice: at the moment, we favor the T9, which costs about 8,500 euros more than the aerated concrete.

So overall, it’s not easy to decide which wall construction is the best. We are still pondering...
In the end, you have to consider what it should cost.
