What type of backing is commonly used behind stucco for easy installation of hoods?

The use of wood as backing behind stucco for the installation of hoods is common due to its accessibility and ease of use. Wood provides a stable and solid surface that allows for secure attachment of various components, such as ductwork or hoods, ensuring that they are reliably fixed in place. The lightweight and pliable nature of wood make it simpler to cut and shape to fit the specific requirements of the installation. Additionally, using wood can simplify the process of fastening with screws or nails, offering a practical solution during the construction phase.

In the context of stucco applications, the wood also serves as a proper substrate that accommodates the expansion and contraction associated with changes in temperature and moisture, which is essential for maintaining the integrity of both the backing and the stucco finish. Other materials, while potentially viable, may not provide the same balance of ease of installation and flexibility as wood does in this particular setting.
