Expert engineering and signature technology make OpenUp® superior. We use our proprietary technology for every window. This makes your window both visually pleasing and structurally sound.
We also offer many glass options and include the benefit of retractable screens. We build every window to your exact specifications, ensuring it lasts.
OpenUp® is a revolutionary new window. We combine the best of wood and aluminum that gives you the best of both worlds.
This construction ensures your window lasts while getting the perfect mix of strength, thermal insulation, and natural beauty.
To ensure a strong window structure, we use heavy extruded tubular aluminum. This delivers superior strength and durability. It does not sacrifice longevity.
However, we use Accoya® wood for the sash interior and frame. Accoya® provides natural beauty and a rich finish. Furthermore, it better withstands the elements. It resists damaging pests, including termites.
The Accoya® material is sustainably sourced and fully recyclable. First, it is harvested following a 12-year growth cycle. Then, treated with an all-natural pickling process. This uses an organic vinegar solution. Consequently, our windows are more durable and more cost-effective. We guarantee they are longer-lasting than any other window.
OpenUp® pass-through windows connect your indoor and outdoor spaces. However, sometimes you need to keep bugs out. You still want the benefits of an open window.
Gas strut windows need an active opening. You easily pass food and drinks back and forth. Therefore, fixed screens are not an option. OpenUp® provides the perfect solution: integrated retractable screens.
We selected standard glass to meet most needs. However, we did not ignore extreme weather or codes.
If your window faces direct sunlight, water, or extreme temperatures, explore more options here.
When you invest in an OpenUp® pass-through window, you can rest easy knowing that no matter what happens—you’re covered.
For the first 10 years, OpenUp® protects every piece of your window apart from the glass. For the next 40 years after that, Accoya® ensures that your wood is safe from weather and pest damage—guaranteed.
