What is the composite facade calculation method?

One of the problems with implementing composite facades is the difference between contractors and employers on how to calculate composite facades. Employers usually base their calculations on the visible surface. In contrast, contractors offer a wide range of composite facades. (What is the composite facade calculation method?)

What is the meaning of the wide surface of the composite facade?

Due to the fact that the composite facade is done as a panel on top, the executed facade has a visible surface on an invisible surface. The invisible surface is the edges of the composite sheet, which are located inside the seam around the composite sheet. In simpler terms, the surface area is the surface of the composite sheet before the return edges are bent.

How much wider is the surface than visible?

In answer to the above question, we must first determine the method of performing the facade. Returned edges have different widths in different installation methods. In general, it can be said that in the fixing installation method, the wide surface of the facade is about 10 to 15% more than the visible surface of the facade. In the Hinging method, this value reaches 15 to 20 percent. This is because in the hanging method, the returned edges are larger due to the width of the punch on the sheet.

Other factors that affect the difference between a visible surface and a wide surface:

As a general rule, any action that increases the number and width of the returned edges in the facade actually contributes to the difference between the visible surface and the wide surface.

One of the things that is effective in this regard is the micro-panel design.

The smaller modules used to make the composite facade panel,
the greater the amount of return edges and ultimately the larger the area of ​​the surface than the visible surface.

Another case is the number of windows and depressions in the facade.

Employers usually multiply the length and width of their facade to remove the composite sheet used and reduce the area of ​​the windows by this amount.

If the windows are practically added to the facade area due to having sheets next to the window and floor and ceiling flanges.

Therefore, in the price analysis and purchase of the sheet, the following items should be considered for accurate estimation of the facade area:

1. Facade implementation method.
2. Facade panel design.
3. Pay attention to facade complications such as depression.
4. Pay attention to the number of windows.
5. Roof flashing design.
