How to build a firewall

[Haidar89]

As the title states. I am going to build a shed, and the wall facing the neighbor must be a fire wall. How do I build a fire wall!
Thanks in advance

Not an expert, but double gypsum is usually used to achieve El30

It depends on the requirements set by the city planning office for the wall. For example, if it's EI30, 2 gypsum boards are enough, or for EI60, 3 gypsum boards on the inside of the wall. Then, everything can be complicated, but this is the most common solution.
