Impact Multi-Track Sliding Doors
Impact multi-track doors use three or more sliding panels that stack to one or both sides, opening a wide section of wall to your lanai or pool. Storm Pro Window and Door installs multi-track impact sliding doors with laminated glass across Tampa Bay and Southwest Florida.
What Is a Multi-Track Impact Door?
A standard slider has two panels. A multi-track door adds tracks so more panels can slide past each other and stack together, which leaves a much wider clear opening. They are a popular choice for large openings onto a screened lanai or pool deck.
Every panel uses laminated impact glass, and the frame is anchored to the product approval so the whole door is rated as opening protection.
Why Homeowners Choose Multi-Track Doors
Wide openings
More panels stack out of the way, so you open more of the wall.
Indoor-outdoor living
Connect the living room to the lanai or pool deck.
Hurricane protection
Laminated impact glass protects the opening with no shutters or panels to put up.
Custom sized
Panel count and configuration are built to your opening.
Is a Multi-Track Door Right for Your Opening?
Multi-track doors need a wide opening and a solid, level floor. For narrower openings, a two-panel impact sliding glass door or impact French doors may be a better fit. We measure every opening and check the design pressure your address requires.
Choosing Your Multi-Track Doors
Panel layouts and frame materials for impact multi-track doors.
Which multi-track layouts are available?
Stack to one side
Three or more panels slide past each other and stack at one end of the opening.
Bi-parting
Panels open from the center and stack to both sides, often in a four-panel layout.
Panels slide into a wall pocket for a nearly open wall. This usually needs added wall work, which we review before quoting.
Built to your opening
Panel count and layout are matched to your opening width and the design pressure it requires.
Custom sizes are available. The larger the opening, the more it matters to match the approved design pressure to your home’s requirements, which we handle in every quote.
Vinyl or aluminum frames: which should I choose?
Vinyl
Vinyl insulates well, resists corrosion and needs little maintenance. A strong pick for energy efficiency in typical openings.
Aluminum
Aluminum is strong and slim, allowing larger glass and narrower sightlines for big openings and water views. It conducts more heat, so glass selection plays a bigger role in efficiency.
We walk you through the ratings, look and efficiency of each for your specific opening.
How Impact Multi-Track Doors Perform
How multi-track doors handle heat, glare and everyday use.
Do multi-track impact doors help with heat and energy bills?
Laminated impact glass with low-E coatings can reduce solar heat gain and fading, and tight interlocks cut drafts. Look for the product’s performance label; the National Fenestration Rating Council (NFRC) explains what the numbers mean. Learn more about energy-efficient impact windows.

How long does a multi-track install take?
Many multi-track doors are installed in a day by our in-house crew, and very wide openings can take longer. We confirm the schedule with your quote. We pull the permit, protect your floors, remove and recycle the old door when possible and clean up. We never install into a rotted or structurally unsound frame. See the impact door installation process.

Frequently Asked Questions
How many panels can a multi-track door have?
It depends on the width of the opening and the product line. We confirm the configuration at your free in-home quote.
Can I replace an existing slider with a multi-track door?
Often, if the opening is wide enough. Larger changes to the opening can require additional work, which we review before quoting.
Do you handle the permit?
Yes. Storm Pro secures the permit and coordinates the final inspection. See our door installation process.
Are multi-track doors impact rated?
Yes. The multi-track doors we install use laminated impact glass and carry a Florida Product Approval or Miami-Dade NOA for the configuration installed.
Should I choose vinyl or aluminum for a multi-track door?
Aluminum is common for very wide openings because its strength allows larger panels and slimmer frames. Vinyl insulates well and resists corrosion. We recommend a frame based on your opening size and the design pressure it requires.
Do multi-track impact doors count for wind mitigation credit?
Approved impact doors count as opening protection. The credit usually requires every glazed opening to be protected and documented. See our wind mitigation guide.
