The partition walls in the house were made 20 cm thick. Showing why so thick

After I poured the monolithic area between the slabs and folded the column supporting it (about this articles here and here) - it's time for the last partition wall in the house.

Marked the positions of the blocks relative to the parallel (outer) wall of the house. He pulled on the lace, mixed the mortar and started laying the first row. The work is already familiar, level control in three planes. An important point - you do not need to immediately remove the excess solution from under the blocks. Otherwise, it may tilt.

From these photos it is already clear why blocks of such thickness were needed for the partition wall. Usually, they are erected from blocks of aerated concrete with a thickness of 100-150 mm. I decided to hide ventilation ducts with a diameter of 10 cm inside the wall.

To do this, I drilled holes inside the blocks with a crown with a diameter of 12 cm.

The wall blocks were anchored with fiberglass reinforcement to the outer wall. An example from a different location in the masonry.

There will be three ventilation ducts in this wall. One comes from the first floor from the kitchen and two from the rooms on the second floor.

The empty space between the blocks and the channel was filled with debris of aerated concrete and filled with glue. I brought the canal pipes 0.5 m above the future overlap. Temporarily drowned them out (from the rain). I did the same in the partition wall in the bathroom area.

Such thick walls will also have greater thermal inertia. In the heat, they will heat up more slowly, and if the electricity is turned off and the boiler does not work, they will cool down longer. Because wall next to a brick pipe, it will also be an additional heat accumulator.
