ᐅ Perlite-filled bricks (polystyrene, pesticides)?

Hello everyone,

We are considering using perlite-filled bricks. However, I have already heard negative comments from two different construction companies:
- Polystyrene is used in the manufacturing process, so the bricks would contain "toxin-filled gas chambers."
- The perlite is treated with pesticides.

I was able to verify online that polystyrene is indeed used in production, but I couldn’t confirm the other claims. Can anyone provide some insight?

Thank you.

If you want a higher energy saving standard without considering solar, photovoltaics, and the like, it won’t be possible otherwise. Or for soundproofing reasons.

You won’t achieve a KfW 40 house with unfilled bricks, I agree with you there, but a KfW 55 house can be achieved with good building components.

Stone by stone, the construction was completed quickly for us. We wanted Passive House standard, but the first few simply dismissed or laughed at the idea.
At that time, I got the impression that filled concrete blocks, no matter with what, are as popular as athlete’s foot.

Homeowners are consumers and think in images or associations. A pastry with pudding costs more at the bakery than one without, and many customers find it tastier. This applies to bricks as well—especially since the mind recognizes that these are two completely different things. When Dad says "no," you ask Mom—the process involves both logic and emotion.

From a technical perspective, integrating foam insulation into the cavities of the bricks rather than applying it on the outside results in a minimal saving in wall thickness. Foam insulations have the advantage over loose-fill materials that they don’t settle inside the cavities. Overall, bricks are the favorite of eco-label enthusiasts—including those who drive an SUV to the farm shop. Only solid wood surpasses them—small dogs are cuter, but you can’t build houses with them.

Hey @11ant, I’m about to pinch you. Don’t say anything against solid wood builders. Not everyone believes that they are installing an ecological miracle solution. I’ve already been criticized enough for not praising that stuff to the eco-heavens.

Not in general – for example, not against the timber frame carpenter or companies like Wir Leben Haus. But there are quite a few providers who simply operate under the motto "Sex sells, organic even more," opening wallets with eco-gimmicks that almost border on indulgence selling.
