What is one way to facilitate ducting installation into a building?

Using exterior doors for duct openings is a practical approach to facilitate ducting installation into a building. This method not only allows for easier access when connecting ductwork but also helps maintain a cleaner and more controlled environment during the drying process. It minimizes the chance of debris or contaminants entering the building and ensures that the ducting can be securely and effectively positioned without the complications that come from using interior access points, which may involve navigating through various spaces that could obstruct installation.

Other options like blocking windows to prevent water entry may not be directly related to the installation of ducting, and installing ducts directly onto grass could lead to complications such as moisture and dirt interfering with the system. Additionally, keeping all doors closed during installation would restrict airflow and access, making the installation process more cumbersome and less efficient. Therefore, utilizing exterior doors for duct openings stands out as the most effective method for facilitating the installation.
