How thick should an outer wall be?

Walls of 25 cm thick

Hello, good, to see if you can clarify a doubt, How thick are the exterior walls for a single-family house and the interior partitions of division of the holes in the house?

Hello, good, let me ask you if you can clarify a question, how thick are the exterior walls for a single-family house and the interior partition walls for dividing the openings of the house?

The thickness of the exterior walls, facade enclosure, that is a much more serious matter, firstly, in facade it is likely that the walls adopt structural function (load-bearing walls) so the thickness of the same is the responsibility of the designer as it will be his responsibility to ensure the stability and strength. In addition, with the current legislation and regulations, the “traditional” half-foot walls of brick masonry with cavity, insulation and interior lining (between 25 to 30 cm) are growing in thickness given the current need to justify in the execution project a specific energy demand limitation depending on the area / province of the country as well as a minimum energy rating of B, which translates into greater insulation thicknesses to contain the heat / cold inside the building, the better the exterior insulation, the shelter of the house, the lower the power and needs of facilities for air conditioning and, as I said before, always depending on the climate zone.

Thickness of interior walls

In this way the interior wall remains in contact with the different floors and the exterior wall passes freely without any joint, in front of the floors, except in cases where overhangs appear.

In the wall openings, so that there is no thermal bridge in jambs, lintels or window sills, the window frames of the enclosures must be placed in the air chamber opening located between the two walls. It is fixed in one of the sashes, never in the two joints, since these have different movements and could generate tensions in the carpentry.

In this type of exterior enclosure, it is not advisable to install a thin partition wall even if it has no structural function. This is because the outer leaf, even if it is not load-bearing, is the part most exposed to external agents.

A thin, lightweight wall has little thermal inertia, and the materials of which it is composed cannot absorb these changes, which cause movements and generate cracks on the surface. These effects reduce the impermeability and durability of the wall, and the visible deterioration detracts from the façade.

Thickness of load-bearing walls

We are planning an exposed concrete wall as an exterior enclosure for a single-family house. It is close to the sea, so that the cladding will not be less than 45 mm (environment IIIa). (What is the minimum thickness for a correct concreting?

You have built a single-family house in fair-faced concrete (including the roof) in an environment close to the sea and you must have taken precautions including a good waterproofing additive for the roof.

Is it possible to make non-structural concrete walls as exterior enclosures with only one reinforcement in the middle of the wall?… I suppose so, then a 12 cm wall would be more than enough, wouldn’t it?

What does mariano mean by reinforcing it with glass fibers?…. if I make a 12 cm concrete wall for the previous purpose with glass fibers in its composition… would it not be necessary to reinforce it to make an enclosure of 3.5 meters high for example not structural?

Exterior wall thickness

The brick wall is the basis of all construction. All types of exterior and interior walls can be made with solid ceramic pieces, even if they have holes to facilitate installation and provide strength. They can be used to build structures for a house, a shed or a perimeter wall to divide a property. They are finished by plastering or covering them with stone.

The laying of bricks or blocks to build walls has a fundamental theory that must always be complied with. The horizontal and vertical joints must have the same thickness. The vertical joints must be as far as possible in the center of the lower and upper brick. In this way the vertical joints alternate every two rows, providing the greatest strength and stability to the wall.

2.1. The string should slide easily over the rulers and should be easy to remove and replace. It must also provide adequate tension to mark the line at the same height in each row.
