ᐅ Sand-lime brick, aerated concrete, or similar materials?

Hello everyone,

we are about to buy a house and want to modify the kitchen layout a bit.

This means the non-load-bearing wall (about 6m² (65 sq ft)) will be removed, and a new wall will be rebuilt slightly offset by 1m (3 feet) towards the back.

Part of the kitchen will be installed on one side of this wall, and various electrical outlets, switches, and pictures will be mounted on both sides, depending on the location.

So the question arises: how thick does this wall need to be, and what kind of blocks or bricks should I use, considering that quite a few things will be fixed or mounted on it?

Price is somewhat important, but we don’t want to cut corners in the wrong areas.

Here are some blocks that come to mind:

Silka calcium silicate block 2DF-L 240 mm x 115 mm x 113 mm (9.4 in x 4.5 in x 4.4 in)
Silka calcium silicate block 3DF-L 240 mm x 175 mm x 113 mm (9.4 in x 6.9 in x 4.4 in)
Ytong plan block 599 mm x 199 mm x 175 mm (23.6 in x 7.8 in x 6.9 in)

What would you recommend, or is there a good YouTube video on this topic?

Hi,
I would go with a calcium silicate plan block. The 17.5 cm (7 inches) one is 50 cm (20 inches) long and can be glued. You can hang quite a lot of weight on it, and due to its size of 50 x 17.5 x 25 cm (20 x 7 x 10 inches) (L x W x H), you can quickly build a wall with it.
Best regards,
Thomas

If my information is up to date, only sand-lime brick has the advantage that the wall does not need to be tied in, meaning it can simply butt against the other walls. This is an important consideration for DIY builders. On the other hand, plan blocks are more user-friendly for homeowners than traditional masonry with mortar joints. For non-load-bearing walls, 11.5 cm (4.5 inches) thickness is sufficient.

I assume we are talking about a house with concrete ceilings (or equivalent) – with wooden beam ceilings, masonry walls where there are no beams underneath would not be a good idea.

With the 17.5cm (7 inches) walls, however, you have much more flexibility when it comes to chasing for cables. Horizontal chasing is allowed as well. Or do the regulations for cable chasing only apply to load-bearing walls?

The block will weigh about 30 kg (66 lbs) in that size. Without a crane, nothing will go quickly...

Hello,

@tempic: the stone weighs 27 kilograms (60 pounds).

I used it for the stair supports at my place. It was easy to work with. My interior walls are all made of 24cm (9.5 inch) calcium silicate bricks, which weigh only 21 kilograms (46 pounds). But in return, you get a solid wall that won’t be toppled easily.

And the sound insulation is also excellent!
