Hello,

I would like to hear your opinion today.

We plan to build our single-family house monolithically, that is, without external thermal insulation composite system (ETICS) or external wall insulation. We have basically decided on the Poroton T9. Now there is also the T9 filled with perlite or mineral wool, as well as the T8. The filled T9 has the same thermal conductivity (lambda value) as the unfilled one. The unfilled T8 is 0.01 better.

The price of the filled version is higher, and of course, the T8 is more expensive as well. Could you please help me and share your opinions on the individual blocks?

One request: please no discussions about the pros and cons of monolithic construction with Poroton, as with all building materials, there are corresponding advantages and disadvantages.

Thank you.

We built monolithically with the standard T9 and would do it again.

We chose the unfilled version because the filled one isn’t better in terms of thermal insulation, only more expensive.

Our architect advised against the T8 because the webs are so thin that they break under even minimal load.

With us, the T9 will also cost about €7,000 plus VAT more.
We will probably go with the T9 as well and invest the money in a central controlled residential ventilation system. It is really difficult to make a decision.

We also want to build monolithically. I have the same question about T8 or T9. Does anyone have information on the price difference in €/m³?

Hello Daytona,

I don’t have the exact price difference, but you can roughly estimate it from the manufacturer’s "selling price." The standard T8 is about 25% more expensive than the standard T9. I think you can infer it somewhat from that; otherwise, it all depends on the discount from the home builder, etc....

Hello,
we chose the T8 model, but uninsulated. We requested prices from the shell constructor. So, they calculated the T9 and then added the additional costs for the T8 and T7 as alternatives. You should do the same.
