Spotlight on Mortise-and-Tenon Construction

Beautiful, clean look | Stronger corner joints | A true sign of quality

While traditional mortise-and-tenon joinery has been used for thousands of years by quality woodworkers around the world, less expensive windows are typically glues together which can produce unsightly corner welds. We believe our customers deserve a better looking and better quality window. We’ve combined new manufacturing technology with traditional mortise-and-tenon corner construction to create a more beautiful window with unprecedented performance. As the replacement window division of Andersen Corporation, we build our windows to last year after year.

Beauty in the Details

Our mortise-and-tenon corner construction eliminates those unsightly corner welds seen in many vinyl windows so all you see is smooth, clean lines that enhance any view.

Stronger Performance

Our mortise-and-tenon corner construction provides greater strength and durability which means your window won’t sag even after several years. In fact, our mortise-and-tenon joinery, combined with our Fibrex® composite framing material, is so strong that we can provide one of the largest gliding window sizes in the industry. So you can easily enjoy those breathtaking views without sacrificing performance.
