Vertical Triple-Track
About this storm window
Built around a reinforced tubular aluminum frame with three independent channels, this vertical unit pairs upper and lower glass panels with two fiberglass screens divided by a fixed meeting rail. The hollow-tube extrusion resists deflection on tall openings where flat-stock frames tend to flex, and the dual-screen layout lets you ventilate the top, the bottom, or the entire window without compromise. Engineered as a long-service exterior upgrade for owner-occupied homes in mixed-climate regions.

What's built into the frame
- Offset frame. The frame sits out from your existing window, so the sashes slide freely and a layer of still air sits between the two windows.
- Sealed on every side. Weatherstripping runs the full perimeter where the frame meets the sashes. Interlocks at the meeting rail, sill and head, plus wind deflectors at the top and bottom, cut down on rattles, dust, pollen and drafts.
- Mold- and mildew-resistant seal. The perimeter weatherstripping is made to resist mold, mildew and pollen.
- Spring-loaded sash locks. Nylon locks hold each glass and screen insert firmly in place.
- Fits slightly out-of-square openings. A peel-type mounting flange lets the frame size be adjusted for an opening that is not perfectly square.
- Flexible mounting gasket. A dual-density gasket around the mounting flange acts as a thermal break, reducing energy transfer through your existing window.
- Powder-coated finish. A durable powder-coat finish holds its color.
How to measure
- Record three widths, three heights, and the exact meeting-rail height.
- Mark the smallest verified opening width and height as fit checks.
- Confirm the mounting surface is deep enough for the three-track frame.
Installation and care
- Set the frame square and level before tightening all fasteners.
- Test every glass and screen panel before completing perimeter sealing.
- The frame does not come with pre-drilled installation holes. Use the correct drill bit to make pilot holes, then fasten it with suitable exterior wood screws.
- Apply exterior-grade caulk across the top and down both sides. Do not caulk the bottom edge.
- Exterior storm windows have weep holes at the bottom of the frame so moisture that collects between your existing window and the storm window can drain out. Never caulk over the weep holes.

FAQs
What is the Vertical Triple-Track Storm Window?
The Vertical Triple-Track Storm Window is an exterior storm window made to the exact width and height of your opening. It fits a double-hung window that opens up and down. The panes slide up and down in their tracks.
Does the Vertical Triple-Track Storm Window include a screen?
Triple-track combinations carry two glass panes and a screen so you can change position through the seasons.
Which frame colors does the Vertical Triple-Track Storm Window come in?
Silver (mill), White, Tan, Bronze and Black. Choose the frame color on the product page after you enter your measurements; the preview image updates to match.
How do I measure for the Vertical Triple-Track Storm Window?
Choose how your window mounts: blind stop, overlap or window track. Measure the width at the top, middle and bottom and record every reading exactly as measured. Measure the height down both sides, stopping at the bottom of the drop on a drop sill or at the highest point of the sill on a standard sill. Do not add or subtract an allowance. We keep the readings for fit review and build only to the dimensions confirmed for the order. Our vertical window measuring guide covers each step.
Which mounting method am I?
Look at how an exterior storm window would attach. If there is a blind stop, a narrow strip of trim set against the window frame, it attaches into the blind stop. If the window has flat casing around it and the storm would sit on the outside face of that trim, it is an overlap mount. If the window has a screen track the storm can slide into, it is a window-track mount. Choose yours in our measuring guide and the steps change to match; if you are not sure, send photos and we will tell you.
Do you add or subtract anything from the measurements I enter?
No. Enter every measurement exactly as taken. Do not add overlap or subtract clearance. We keep all readings for fit review and build only to the dimensions confirmed for the order.
Is the Vertical Triple-Track Storm Window right for my window?
Choose it when your existing window is a double-hung window that opens up and down. If you are unsure how your window operates, send us a photo and we will point you to the right style.
Does the Vertical Triple-Track Storm Window have weep holes?
Yes. Exterior storm windows have weep holes at the bottom of the frame so moisture that collects between your existing window and the storm window can drain out. Never caulk over the weep holes.
What affects the price of the Vertical Triple-Track Storm Window?
The width and height you enter, the frame color and the glass you select set the price shown on the product page. Oversized openings may need a quote, and shipping and tax are calculated at checkout.
