ᐅ Garage built with sand-lime bricks or aerated concrete blocks

Hi everyone,
Our construction company planned a garage with the following specifications:
- 6 x 9 meters (5 meters (16.4 feet) wide garage door)
- Strip foundation and paved floor
- Hipped roof with an 18° (18 degrees) pitch
- 17.5 cm (7 inch) Ytong PP6 blocks (<----- we haven’t decided on this yet)
- Plastered finish
- Unheated
- Structural engineering checked and approved
The garage will primarily be used for parking, but also as a training space and occasionally for social events. Now the question is whether sound insulation or the thermal properties of Ytong are more important.
My idea was to build the garage with 17.5 cm (7 inch) sand-lime bricks, add a ring beam at the top, and then the hipped roof. The construction company, however, recommends Ytong instead. If I don’t want the 17.5 cm (7 inch) Ytong, they suggest using 24 cm (9.5 inch) Ytong blocks.
What do you think? What would you recommend? Does anyone have a garage made of Ytong and not regretted it? Is it not too noisy? Does Ytong really keep the garage warm? Or is sand-lime brick the better option after all?
It’s my decision, of course, but I’m really struggling with it.
Thanks in advance!
Good luck

I plan to discuss the topic of sand-lime bricks versus aerated concrete blocks (Ytong) there before making a decision. Both have advantages and disadvantages, and I haven't decided yet.

Now the question is whether sound insulation or the thermal properties of Ytong are more important. My idea was to build the garage with 17.5cm (7 inches) sand-lime bricks, with a ring beam on top and a hipped roof. The construction company advises me to use Ytong instead. If I don’t want 17.5cm (7 inches), then to build it with 24cm (9.5 inches) Ytong blocks. You can build a garage under Energy Saving Regulation 1648 without any real requirement for thermal insulation. Furnishing it with brewery-style benches for every barbecue is no problem, but using it as a fitness room makes it a living space, which can jeopardize its exemption from setback regulations and may also mean it no longer counts as a parking space. A hipped roof will cost more than you could save by doing the masonry yourself. For DIY builders, formwork blocks would be even more suitable here—choose something affordable for an outbuilding like this; there’s no need for handcrafted premium blocks. Only formwork blocks or plan blocks should be used, always without bed joints for amateur masons. Using sand-lime bricks doesn’t make sense: even if the world is known to fall apart beautifully, it’s just a garage, and you can always overdo it (but don’t have to).

I would not agree with the recommendation for shuttering blocks, as mixing concrete is time-consuming, and delivered concrete usually lacks the necessary tools. Calcium silicate blocks are definitely not nonsense but rather the best choice because they offer the most important properties for a garage: stability, allowing you to hang heavy items securely, and space efficiency. When building yourself, the only advantage of aerated concrete blocks is that they are easier to work with using a saw.

Sand-lime brick is not nonsense at all but rather the preferred choice, as it offers the most important properties for a garage. Stability, so you can hang things securely, and it’s space-saving. By nonsense, I meant exaggerated. And as I said, feel free to choose whatever is available that day. When I read these praises for sand-lime bricks compared to porous bricks or similar, I always think of the “good butter” that people born in the Imperial era preferred over margarine, just out of principle. Keep in mind, we are talking about a garage here, where even a butcher would consider tofu good enough. In the garage, you hang bikes on the wall, not motorcycles (especially not with sidecars) — and if you do: there’s probably something suitable in Artur Fischer’s product range for that too.

Furnishing it with brewery-style tables and benches for every barbecue party is no problem – however, using it as a fitness room turns it into a habitable space, which may invalidate its exemption as a structure built on the property boundary. Additionally, it would no longer meet any possible parking space requirements. A hip roof will cause more extra costs than you could save by doing the masonry yourself. Regarding suitability for DIY masons, insulated formwork blocks would be even better here – use something for this outbuilding that you can get at the price of daily soup; it does not need handcrafted special blocks. Only insulated formwork blocks or plan blocks should be used, and for amateur masons, always without mortar joints. Using sand-lime brick is nonsense: even if the world is famously going downhill magnificently, it’s just a garage, and you can overdo everything (but you don’t have to). By training room, I meant activities like hanging a punching bag, setting up a boxing dummy, jump rope, etc. The garage is not intended to be fully filled with equipment. In addition, I have four parking spaces in front of the garage.
Insulated formwork blocks are not an option; only the first two rows will be built with them, because we need to raise the foundation.
It is also about sand-lime brick as Ratio plan block, which nowadays is glued without joints. Installation is similar to aerated concrete blocks, only cutting is somewhat more difficult.
At the moment, my preference is for 17.5 cm (7 inches) sand-lime brick.

At the moment, I’m leaning towards 17.5cm (7 inches) sand-lime bricks. Apart from considering it unnecessary, sand-lime brick is not a bad choice here. 17.5cm (7 inches) is more than sufficient. Plan bricks are generally glued in the bed joint instead of being mortared, and leaving out the vertical joint is soon becoming standard practice. Don’t underestimate the weight; the difference compared to aerated concrete blocks is more significant in terms of weight than workability. We also have a thread on the topic of doing sports in the garage here: https://www.hausbau-forum.de/threads/hoher-und-beheizter-Sport-Raum-neben-der-Garage-Ideen-gesucht.32931/
