📏 How to Order Your Custom Plexiglass AC Panel

Please follow these steps carefully to ensure an accurate fit.

1️⃣ Measure the Surface Your Panel Will Sit On

Your custom AC panel is designed to mount onto the frame surface around your window opening.

Important:

Measure the full outer dimensions where the panel will rest.

  • Do not measure the inside opening only

Your final dimensions should represent the actual overall size of the plexiglass panel.

2️⃣ Account for Window Hardware

If your window includes:

  • Handles

  • Cranks

  • Locks

  • Latches

  • Any protruding hardware

You will need to include notches or cut-outs so the panel can sit flat against the frame.

These notches are CNC-cut into your custom panel during fabrication.

✔️ Recommended Clearance

We recommend a minimum of 1/4" clearance around hardware cut-outs for proper fitment.

📌 Need Help?

We recommend:

3️⃣ Select Your Correct Size Range

Choose the pricing range based on the smaller dimension of your panel.

Example:

If your panel measures 19” W × 49” H, your smaller dimension is 19”, so you would select “18”–23” from the drop down menu.

Selecting the wrong size category may delay production.

4️⃣ Design Your AC Panel & Place Your Order

👉 Use our AC Panel designer to:

  • Include the exact height and width of your custom panel

  • Position your exhaust hole

  • Add any required notches for handles or hardware

After using our AC panel designer, place your order online and email your panel design to design@klolab.com and include a photo of your AC hose adapter so we can match the exhaust hole precisely.

If you prefer, you can also send a hand-drawn diagram and a photo of your adapter.

We’ll use this information to create your final design proof. These are the exact dimensions used for fabrication.

How to Measure Your Window for a Custom Plexiglass AC Panel (Perfect for Portable AC Units)

Need a clean, modern solution for sealing your window when using a portable air conditioner? In this step-by-step video, we show you exactly how to measure your window frame — not the opening — to order a perfectly fitting custom plexiglass AC panel.

How to Measure Your Window for Your Custom Plexiglass Panel

To measure your window for a custom plexiglass AC panel, follow these steps:

For a casement window or a swing-out window- For casement or swing-out windows, the plexiglass panel will sit on your window frame and be held in place with the Velcro we provide. To make sure it fits properly, we may need to cut notches around any hardware so the panel can sit flat. Please allow for about 1/4" of extra space on each side of the notch. For example, if a piece of hardware at the bottom of the frame is 2" wide, the notch should be at least 2.5" wide to give it enough clearance.

If the notch is on the side, add that same 1/4" of extra space to the height instead. To measure the height of a bottom notch, measure from the bottom edge of the panel up to where the window opening starts. For side notches, measure from the edge of the panel to the window opening.


For a sliding window, you can add a partial plexiglass panel. In order to keep your plexiglass panel structurally sound, we recommend leaving a minimum of 4” on either side of the cut-out that your AC adapter will go into.

Open your sliding window to the size you’d like your plexiglass panel to be. Find the height by measuring from inside the top track to the window frame edge on the bottom. It’s important not to measure inside the track at the bottom of your piece since it will make your panel too large for your window.
