A pass through window gives you an active opening between two spaces instead of keeping them separated by a standard window or wall opening.
OpenUp® pass through windows are designed for homes and businesses and can be used in kitchens, bars, pool houses, and indoor-outdoor spaces. They make it easier to serve food and drinks while maintaining a more open connection between the people on both sides.
Each OpenUp® window is custom-built to order and combines minimalist framing, insulated glass, extruded aluminum, and Accoya® wood.
OpenUp® specializes in gas-strut awning-style pass through windows. The awning-style design moves the window panel above the active opening, leaving the space below available for serving, entertaining, and conversation.
OpenUp® combines this design with narrow sightlines and a larger glass area. Its original design provides 33% more view when the window is closed and allows more natural light into the space.
OpenUp® offers gas-strut pass through windows designed to create an open connection between indoor and outdoor spaces. The gas-strut system helps lift and support the window panel while keeping the pass through area below open for serving, entertaining, and conversation.
OpenUp® combines gas-strut operation with minimalist framing, structural extruded aluminum, Accoya® wood, and insulated glass. The result is a custom pass through window designed for homes and businesses, including kitchens, bars, and pool houses.
OpenUp Windows combines a wide pass-through opening with durable materials, custom sizing, and several operating options.
OpenUp® uses custom aluminum extrusions and narrow sightlines to maximize the visible glass area. According to OpenUp®, the design provides 33% more view when closed, helping maintain wider sightlines and allowing more natural light indoors.
OpenUp® combines its extruded aluminum exterior with Accoya® wood on the interior. Accoya® is PEFC and FSC certified and described as 100% non-toxic. It has been tested for dimensional stability, durability, and paint retention and grows in responsibly managed forests.
OpenUp® uses extruded aluminum as part of the window structure rather than simply wrapping a wood window with a thin aluminum layer. In a comparison with an aluminum-clad wood window, OpenUp® found its aluminum material to be more than 30 times stronger in horizontal wind-load resistance.
OpenUp® manufactures its own windows. Each pass through window is precision-engineered by computer and built by a dedicated team member. The OpenUp® team brings more than four decades of experience in window design, manufacturing, and installation.
OpenUp® offers a retractable Pleated Screen for pass through kitchen windows. It provides insect protection when needed while staying out of the way when you want access to the full opening.
The Pleated Screen works with any size OpenUp® window, comes factory-mounted before shipping, and is available with a white or black painted frame.
The standard OpenUp® option uses 1-inch insulated glass made with two pieces of 3/16-inch tempered glass separated by a black spacer.
This creates a 5/8-inch air pocket between the panes, providing twice the insulation of a single pane. Argon gas can replace the air between the panes to add more insulating value.
Customized glass options include:
For sunny climates and southern states, OpenUp® recommends triple-silver coatings for maximum solar protection and efficiency.
OpenUp® also offers the VENTABLE Picture Window for homeowners who want a large glass area with full operability. The VENTABLE opens from top to bottom and provides 20% or more airflow than traditional combination windows. With up to 50 square feet of glass, it is designed to create an unobstructed panoramic view with fewer visual interruptions from wood panels or bulky frames.
Its modern, minimalist design makes it another OpenUp® option for spaces where airflow, a larger view, and a clean appearance are priorities.
OpenUp® pass through windows combine minimalist framing, insulated glass, extruded aluminum, Accoya® wood, and custom manufacturing in one window system. Explore the available glass, Pleated Screen, sill, and technical options for your Irvine project, then contact the OpenUp® team when you are ready to discuss your window.
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.
All OpenUp® pass through windows are custom-built to order and shipped within 4-6 weeks. Up to 100% faster than the competition on windows of all sizes.
