Step-by-step explanation:
The minimum thickness for a solid garage door to a living area is determined by building codes and regulations.
The purpose of having a minimum thickness requirement is to ensure that the door provides adequate insulation and protection from external elements such as noise, temperature, and security.
In the United States, for example, the International Residential Code (IRC) sets guidelines for minimum garage door thickness. According to the IRC, the minimum thickness for a solid garage door facing a living area is typically 1¾ inches.
This minimum thickness helps to reduce sound transmission, maintain temperature control, and enhance safety for the occupants of the living area. It also helps to prevent potential damage to the door due to impact, such as forced entry attempts.
