Window Combinations Your Way

Create the window combinations homeowners desire with A-Series joining options from Andersen. Whether it’s monumental sizes, dynamic configurations or a combination of both, we offer a joining option to meet your project needs. 

With our reinforced joining options you can achieve multi-directional combinations and meet higher performance requirements. We also offer non-reinforced joining options for projects where performance and design flexibility aren’t a concern. 

Our new Easy Connect Joining System delivers the ultimate in job site conveniences, making it easier to install large combinations. In fact, most contractors surveyed said they could reduce the number of installers by 50% using the Andersen Easy Connect Joining System.*


Reinforced Joining

This patented joining system utilizes interlocking fiberglass joining plates and offers design flexibility without compromising performance. 

Choose a reinforced joining option when two-way combinations are desired or higher performance requirements need to be met. Our three reinforced joining options are tested to AAMA 450, Hallmark Certified for air, water and structural performance** and High Velocity Hurricane Zone (HVHZ) approved. 

**When installed according to Andersen installation instructions.
