Are there any special requirements for installing aluminum windows correctly?

When installing aluminum windows, there are several special requirements to consider: ensuring the frames are level and square, using the correct size and type of fasteners, applying a proper sealant to prevent air and water infiltration, and adhering to local building codes. Additionally, it's crucial to check for thermal insulation properties, especially in areas with extreme weather conditions. The installation should also allow for proper drainage to prevent water damage. Professional installation is often recommended to meet these requirements and ensure the windows function correctly and last longer.
