What source should a contractor consult for the required rough-in information of aluminum clad wood windows?

The best source for the required rough-in information for aluminum clad wood windows is the manufacturer's data. This information is specifically tailored to the products offered by the manufacturer and includes precise guidelines on dimensions, installation practices, and any other specifications that are critical for ensuring proper fit and performance.

Manufacturers provide detailed installation instructions, technical specifications, and rough-in guidelines that are crucial for the successful installation of their products. Using manufacturer data ensures that the contractor adheres to the recommended practices required to maintain warranties and achieve optimal functionality of the windows.

While local building codes, online forums, and construction handbooks can offer valuable insights, they may not provide the specific information needed for individual products. Local codes vary by jurisdiction and may not directly address the requirements for specific types of windows. Online forums can provide anecdotal advice but lack the authoritative and definitive nature of manufacturer data. Construction handbooks may offer general installation guidelines but may not detail specifications unique to aluminum clad wood windows. Therefore, referring to the manufacturer's data is the most reliable approach for obtaining accurate and relevant rough-in information.
