Installation Methods

There are four primary methods of attaching Pella® aluminum-clad wood windows in new construction: fins, clips, receptors and anchorage through the frame.
Fin Installation
Fin installation is applicable when construction methods permit window and door units to be installed from the exterior prior to the application of exterior cladding, such as lap siding, brick veneer or stucco.
Clip Installation
Clip installation is applicable when construction materials or sequence dictates the window units be installed from the interior or after the wall system is completely constructed.
Receptor
Receptors are used for multistory buildings requiring installation from the interior or when a more robust installation method is desired.
Anchor Through Frame
Anchors through the frame are used when wall conditions or construction sequence requires installation from inside the building.
