Our Features Set Us Apart

Founder Ed Page’s expert engineering and signature technology has made it possible for OpenUp® to truly stand apart from its competitors.

2Fold Technology

OpenUp® founder Ed Page has invented a revolutionary new way to construct pass-through windows that combines the benefits of both wood and aluminum. It’s the best of both worlds, and we call it 2Fold Technology. 2Fold Technology ensures your window is built to last—making it the perfect combination of strength, thermal insulation, and natural beauty.

The Best of Both Worlds

To ensure the structure of your window is sound and strong, we opt for heavy extruded tubular aluminum, which delivers superior strength and durability over standard aluminum without sacrificing durability or longevity.

For the sash interior and frame, however, we use Accoya® wood. Not only does Accoya® provide a natural beauty and rich finish, but it is also better able to withstand the elements and resist damaging pests—including termites. Sustainably sourced and fully recyclable, our Accoya® materials are harvested following a 12-year growth cycle and are then treated to an all-natural pickling process using an organic vinegar solution. Because of this, our windows are more durable, more cost-effective, and longer-lasting—guaranteed.

Retractable Screens: Uninterrupted Views, Plus Protection

OpenUp® pass-through kitchen windows are designed to connect your indoor and outdoor spaces—but there will be times that you will want to keep the benefits of an open window without bugs or other critters passing through and making themselves at home.

Gas strut windows are designed to be an active opening, where food and beverages can easily be passed back and forth. Because of this, fixed-in-place window screens aren’t an option. OpenUp® provides the ideal solution with our integrated retractable screens.
