When exposure to sun and rain is an issue, opt for Aluminum Clad/Wood Bi-Fold Windows. We combine a sleek, tough, low maintenance exterior of 1/16" thick extruded aluminum with a rich, warm, all-wood interior to give you the best of both worlds. AG offers 5 standard clad color options. Clad exteriors are painted with 70% kynar 500 and meets a 2605.

We’ll match any manufacturer’s exterior clad color to ensure a consistent look between our products and theirs.

Bi-Fold Windows are available with a flush track system we call the Ultra Guide® for the smoothest transition possible between indoors and outdoors. *Appropriate for extremely low-exposure environments only; no warranty for water penetration with this option.

Pair your Bi-Fold wINDOWS with an innovative and functional retractable accordion screen. This is the perfect solution to screening openings to protect your home from insects and other unwanted elements.

Your optional retractable accordion screen is factory installed and integrated into the jamb, saving you time and money on installation.
