ᐅ Only Poroton blocks or what type of insulation?

We are about to fulfill our dream of building a single-family house. The plot has already been purchased, and the construction company has been selected. Just before signing the contract, the question arose as to which type of brick we should use to achieve optimal sound insulation as well as the best thermal insulation values.

I have been reading up on this for weeks, but so far, I have not found a practical solution.

I am torn between 24cm Poroton (10 inches) with 16cm (6 inches) insulation and 36.5cm Poroton (14 inches) without insulation. I have read that few builders have chosen 24cm sand-lime brick with 16cm (6 inches) insulation and have never regretted it. However, sand-lime brick would unfortunately exceed our budget.

Maybe someone can recommend a good alternative?

Just for your information, the house has 1.5 stories and will feature triple glazing with soundproofing, as well as an air-source heat pump with solar storage and underfloor heating over 116m² (1250 sq ft) of living space. Our concerns about soundproofing are because the plot is not far from an airport and a highway (it is still quieter than in our town, but you never know how much air traffic noise could increase in the future).

I would really appreciate some suggestions.

Best regards.

A 17.5cm (7 inch) sand-lime brick with an R-value of 1.8 combined with 16 or 20cm (6 or 8 inch) insulation could also work.

An air source heat pump combined with a solar thermal system is not the best match. Also, when using an air source heat pump, pay close attention to the Coefficient of Performance (COP) and heating capacity curves in relation to the building’s heating load!
