Price difference WDVS / energy-saving bricks, later costs, single-family house

@Chris: When was that mentioned technical article again? What lambda value did the stones available on the market at that time have – or even better: What lambda value did the bricks have that had already been installed for about ~10 years at that time and could possibly have shown damage?

A facade simply also requires maintenance. If the necessary new coat of paint is neglected over decades, other building physics properties of the used building materials come into play. Yes, then it can be the case that due to greater heat storage capacity and better water vapor diffusion capacity, the brick performs better. But there we are dealing with the scientific decimal place.

Hello karliseppel,

the topic creator was primarily concerned with the question of the surcharge for porous perforated bricks compared to EIFS, not about discussing the contamination issue of EIFS. By the way, this mainly depends on the frequency and duration of dew point undershoots. I don't believe that the differences are really in the "decimal range."
