Blog series part 4 – House construction – Leveling and false frames

In this article, we will discuss leveling and false frames.

You’ ve finished building, and now you see your new house taking shape. You can enter the rooms you designed and dream about life in your new home. As we said, you still have a lot of work ahead, and two important tasks follow: leveling and false frames.


1. What is leveling?

Leveling is the final level of each floor after the flooring has been fully installed. It is usually 10 to 15 centimeters higher than the concrete slab poured during the previous stage of concreting.

2. Why does the final level need to be 10-15 centimeters higher, and why didn’t we make it higher from the beginning?

We need this thickness for various reasons:

A) We need to create slopes on the balconies for water drainage, hence the need for a difference in height.

B) Plumbing, cooling, and sometimes electrical installations are placed in the filling.

C) Often, the house’s heating system (underfloor heating) is also placed in the filling.


What determines the final height I will have?

Initially we calculate the necessary slopes on the balconies, then add the thickness of the aluminum frames along with the marble sills to get our final height. We must ensure that we have the necessary height required for underfloor heating according to its technical specifications.

4. Which crew should I call to correctly measure the leveling?

The crew I personally recommend is the tile setters. They will calculate the necessary slopes on the balconies and are the crew that knows how to do this job. Of course, since this is a very important construction task, it would be good to also call the supervising engineer to ensure we get the correct leveling. The tools used for leveling are a water level or a laser level.

5. Why is leveling an important task?

All other crews will start working based on these heights. Plumbers, electricians, and marble workers need the height to install the plumbing, electrical, and marble correctly.

6. What are false frames?

False frames are frames made of a metal skeleton (usually galvanized) where the external aluminum frames will be screwed.

7. Why are false frames important

Essentially, by installing the false frames, we choose the type of frame to be installed. We define the heights, widths, and type of frames. False frames also give us the interior passage of the house’s walls and will be used by the plasterer as guides.

8. Is there anything else I need to know about false frames?

If we have frames that will include a roller shutter, we can place a metal sheet on the top part of the false frame to be covered later by the thermal insulation work, achieving a more aesthetically pleasing result.
