Good evening,
Our construction company plans to build the exterior walls using an unfilled Poroton T12, 36.5 cm (14 inches) thick. The exterior plaster will consist of a lime-cement plaster between 1.5 and 2 cm (0.6 and 0.8 inches) thick, with a 2 mm (0.08 inch) synthetic resin plaster applied on top. The interior wall plaster will be a machine-applied gypsum plaster.
Is this sufficient for today’s standards? Or would it be better to choose a different Poroton brick?
Best regards, Micha

It all sounds more or less like standard new construction, except for the masonry. You should ask about the price difference for better-insulating masonry; maybe the general contractor (GC) doesn’t charge excessive prices. You won’t get unrealistically high energy savings by improving the U-value from, say, 0.3 to 0.22, but I would consider paying a few extra euros in your place. Do you heat with a heat pump or gas? Making sure the underfloor heating is properly designed and the heating system is well adjusted can sometimes save as much on energy costs as better U-values in the building envelope. Thanks for your explanation. I have also looked into the thermal insulation properties, but at the moment, I am mainly more concerned about the sound insulation value.
We heat with an air-to-water heat pump from Nibe. For the transitional seasons and winter, we have a wood stove.
I will simply ask the GC.
