Measure Twice Order Once

Measure both the interior and exterior; here, the patio was 1” higher than the floor inside. For gas strut or motorized pass-through windows, add ¼” to each side (½” total width) and ¼” from the countertop up when sizing the rough opening.

What happens if you make a terrible mistake and the window just won’t fit?  We will try to resell your window at a discount and credit you back against the cost of the new proper sized window.

We are so happy with our gas strut window. Adam was wonderful to work with. He was very knowledgeable and answered all of our questions and we had alot. Our window was shipped to Florida in a crate that was very secure and came with step by step instructions on how to remove it. It was easy to install. This is a very well made product. Openup Windows definitely takes pride in there work and that is very hard to find these days. We are so happy we decided to purchase from this company. And the window arrived on my Anniversary which made it even more special. Thank you Adam!!

We purchased a 96 x 42 inch window with a 96 x 12 inch transom push out window for the bar in our new 3 season room. The window looks amazing and is the center piece of the room. I spoke with Adam several times during the process and he made me feel very comfortable with this purchase. Adam even drove to our home and helped with the installation. I highly recommend OpenUp windows.

Mike was able to answer the questions I had about getting a new awning window for my kitchen. I ordered the window and it was delivered 4 1/2 weeks later!

We are delighted with our OpenUp window. It has transformed how we use our indoor and ourdoor spaces and really allows us to enjoy our kitchen in a way we couldn't previously. It's early days, but we're delighted with the quality of the product and the price was definitely more reasonable than some of the competition out there. If you're looking for a window that will allow you to bridge the gap between your kitchen and patio/deck, I would definitely recommend you look into OpenUp.

We purchased a window from them to Los Angeles, California. The service was very good. From our experience they will help you also after the purchase.

FAQ's

Most frequent questions and answers

Can the gas strut window be opened partially for airflow?

No. Standard gas strut windows are designed to open fully to 90 degrees or remain completely closed.
If you want the ability to stop the window at any position—such as opening it just a few inches for ventilation—you can upgrade to the Motorized Strut System, which allows precise control and adjustable opening.

No. Using external devices like a KickStand can cause the gas inside the strut to leak if the window is stopped midway.
For maximum durability, the window should always be opened fully or closed fully, which also engages the triple weather seals for complete protection.

Yes. Both gas struts and motorized components are covered under the 10-year warranty, starting from the ship date.
This long-term coverage ensures reliable performance and peace of mind.

Yes. The warranty is fully transferable and stays with the window itself, not the homeowner.
This adds long-term value to your home and makes the product a strong investment for future resale.
