Stacking Door

What a Stacking Door Actually Is

Three or more panels, each on its own track, gathering at one end of the opening.

Stacking glass door open inside a great room with the panels parked against the left jamb

Slide it open and the panels travel along and gather against each other at one end of the opening. They stay in the plane of the wall the whole time, which is what separates a stacking door from a folding one.

What you give up is width. The stack has to park somewhere, and on most systems it parks in front of the panel at the end of the run, so the glass you clear is the opening minus the stack. Those parked panels also stay in view from both sides.

Almost every decision further down this page comes back to that one trade.

The panels park at the jamb

Nothing is built into the wall, so most Phoenix remodels can take one. The parked stack stays in view and takes part of the clear width.

The panels disappear into the wall

The same family of door, carried on past the jamb into a framed cavity. It clears nearly the whole opening and needs a run of wall built to hold the panels.

Sill and thresholdOne track for every moving panel, so the sill is deeper than a slider’s. How it meets your floor decides where water goes.

Exterior ramp

A ramp on the patio side brings the paving up to the sill, so the step is taken outside rather than at the threshold.

Easier crossing, drainage kept

Interior ramp sill for a stacking door, cut away to show the ramp on the inside face

Interior ramp

The ramp is on the inside instead, which suits a finished floor that cannot be cut down to the sill.

Designed to project about 3/16 inch above the finished floor, so there is barely a step to cross.

Not rated for air and water

Frame and panelPanel size narrows this choice. A frame that is fine on a bedroom slider can be the wrong answer across sixteen feet.

Thermally broken aluminum

Strong enough to carry large panels while keeping the sightlines between them narrow. The thermal break slows heat moving through the frame, which matters across a lot of frame. We install IWC’s 8800 Series Ambassador and PRL’s commercially rated systems.

Structural pickWide openings and tall panels in full sun.

Clad wood

Real wood on the inside face, with cladding taking the weather outside. Suits a room where the door is meant to read as millwork rather than as a frame.

Warmth pickInteriors out of long direct afternoon sun.

Vinyl and composite

Costs less than a large aluminum system on a comparable opening, and works well on shorter runs and smaller panels, which covers a lot of real openings.

Value pickMaximum panel size and dark colors are the limits.

The glass package

A stacking door is mostly glass, so the package does more for indoor comfort here than it does on any window in the house. Three specifications carry most of that work.

  • Spectrally selective low-ECuts solar heat and ultraviolet light while the room still reads as bright. Across sixteen feet of glass on a west facing patio, that is the difference between a room you use at four in the afternoon and one you close the blinds on.
  • Dual pane with argonAsk about the spacer as well as the gas. A large insulated unit in the desert goes through a big temperature swing every day, and the spacer is a large part of how long the seal survives it.
  • Tempered or laminatedGlass in a door has to meet safety glazing requirements. Laminated is worth asking about on its own merits too: it blocks more ultraviolet light and quietens outside noise.

Work Through the Options With Us

We walk the opening first, then narrow the configuration to what it can actually take.

Why Choose Noble for Your Stacking Door

A stacking door is a door and a piece of the building at the same time. The opening, the header, the sill, the glass and the installation all have to agree with each other, and on a wide opening there is not much room for one of them to be wrong. Noble keeps those pieces inside one project scope.

  • Structural Work Under One Contract

    Noble Windows & Doors LLC holds AZ ROC #364772, a KB-1 Dual Building Contractor license, plus AZ ROC #364771 for electrical work. If your opening has to be widened or structurally modified, that scope is written into the same quote rather than left for you to coordinate with another company.

  • More Than One System To Choose From

    We install LaCantina, Andersen, Milgard, Therma-Tru, Simonton, IWC, PRL and other established manufacturers. That means we can match the system to your panel sizes, your exposure and your budget instead of fitting your opening to the one product line we carry.

  • A Quote You Can Compare Line by Line

    Your written quote names the system, the panel configuration, the glass specification, the sill and the locking set, with structural scope broken out separately. That is what lets you hold two bids side by side and see where they differ.

  • Slide One Before You Order One

    Operation is hard to judge from a photograph, and it is the thing you will notice every day. Our showroom is at 4001 E Broadway Rd, Unit B-11, Phoenix, AZ 85040, where you can put your hands on a door and compare options with our team.

How We Measure And Install Your Stacking Door

Free In-Home Measure

We measure the opening, check the structure above it and look at the floor and the patio on both sides. Then we talk through panel count, stacking direction, sill type and glass against how you use the room.

01

Written Quote And Scope

Your quote names the system and its panel configuration, the glass specification, the sill, the screens and the locking set. Any work on the opening gets its own lines, with the timeline alongside.

02

Engineering, Permit And Build

Where the opening changes, the structural engineering and permitting move forward while the door is being built to the approved dimensions. Nothing is ordered until those dimensions are confirmed.

03

Installation And Walkthrough

We complete the opening work, set and level the sill, install the panels and adjust the rollers and the lock. Before we leave we walk the door with you, open and close every panel, and show you how to keep the tracks clear.

What Drives the Cost of a Stacking Door

We do not publish a per-door figure, because two openings of the same width can differ by a factor of three and a made-up range would only mislead you. What we can show you is what moves the number, in roughly the order it moves it. Read your quotes against this list, including ours, and you will see what you are paying for.

Whether The Opening Changes

OPENING REQUIREMENTS

If the door drops into the opening you already have, this line can be small. If the opening grows, it brings engineering, a new header, shoring, permitting, inspection and the finish repair afterwards. It is usually the largest single difference between two quotes that look alike on the door itself.

What Affects Your Price

Whether the wall is load bearing and what sits above it
The span the new header has to carry
Electrical or other services inside the wall being removed

Panels, Frame And Glass

DOOR SPECIFICATIONS

More panels means more tracks, a deeper frame and more hardware. Oversized panels can cross a manufacturer's threshold into a heavier and costlier system. On top of that sit the frame material, the finish, and the glass package you choose for the exposure.

What Affects Your Price

Panel count, panel size and the system's weight class
Frame material, and a stock finish against a custom or dark color
Coating, laminated glass, and any acoustic specification

Sill, Screens And Operation

OPTIONS AND OPERATION

A flush sill costs more than a weather-rated one and needs a drainage detail designed around it. A retractable screen across a twenty foot opening is a real line item, not an accessory. Power operation belongs here too, because it changes the frame and brings electrical work with it.

What Affects Your Price

Sill type, and whether the slab has to be cut for it
Screens, and whether they run in a cassette or on their own track
Handles, the locking set, and any power operation

We quote the door and the work on the opening as separate lines instead of one number, so you can compare bids fairly. A quote well below the others usually has one of three things missing: a lighter duty system than the panel size calls for, a plainer glass package than the one you asked about, or structural scope that has been left out and will come back later. Our Phoenix window and door replacement cost guide breaks the wider market down the same way. Ask about current promotions and financing when you book. Whatever applies to your project is written into your quote, in full, before anything is signed.

Stacking Door Installation Across the Phoenix Valley

Based in South Phoenix, Noble Windows & Doors installs stacking doors on replacements, remodels and new builds throughout the Valley, including Arcadia, Paradise Valley, Scottsdale, Ahwatukee and Queen Creek. We look at every opening in person, because the header, the slab, the patio level and which way the opening faces all change what the right door is.

Building New or Remodeling?

A stacking door is far easier to get right when you design the opening around it from the start, instead of cutting it into a wall built for something else. If you are still working from plans, bringing us in early lets the rough opening, the header, the sill detail and the glass specification be settled before anything is framed. We also quote whole-home window and door installation packages.

Work From Your Plans

We review the elevations, confirm the rough opening and the header, and coordinate the door specification with your builder, architect or general contractor before the wall goes up.

Set The Sill Detail Early

A flush or near-flush threshold is a slab and drainage decision as much as a door one. Deciding it while the patio is still on paper is much cheaper than deciding it after the concrete is poured.

Corner And Oversized Runs

Planning a corner unit, a very wide span or a bi-parting layout? Those need the structure above the opening designed for them, so the sooner the door and the beam are looked at together, the better.

Code And HOA Requirements

We help identify the energy, safety and installation requirements that apply, including the documentation an HOA or a local design review may ask to see before approving a change to an elevation.

Stacking Door FAQs

What is a stacking door?
A stacking door is a wide glass door built from three or more panels, where each panel that moves runs on its own track. When you open it, the panels slide along and gather against each other at one end of the opening, staying in the plane of the wall. They are also sold as stacking glass doors, stacking patio doors, stacking sliding doors and multi slide stacking doors.
How is a stacking door different from a folding glass wall?
A folding glass wall has panels hinged to each other that fold up like a concertina and end up projecting out of the plane of the wall. A stacking door has panels that slide independently and stay in the plane of the wall the whole time. A folding wall clears more of the opening; a stacking door keeps the patio and the room clear of the panels and is simpler to use day to day.
What is the difference between a stacking and a pocketing multi-slide door?
They are the same family of door. On a stacking version the panels park against each other at the jamb, where you can still see them. On a pocketing version they keep traveling past the jamb into a cavity built inside the wall and disappear. Pocketing gives the cleaner open view and needs a run of wall built to hold the panels, which is why it is more common on new builds.
How much of the opening does a stacking door clear?
Usually about two thirds to three quarters of the width, depending on the panel count and whether any panel is fixed. On a three panel door with two moving panels you clear roughly two thirds. On a four panel door with three moving you clear roughly three quarters. A bi-parting layout splits the stack to both ends and clears the whole center.
How many panels can a stacking door have?
Three, four and six panel runs cover most Phoenix homes, and wider systems exist. Every extra moving panel adds a track, so the head and the sill get deeper as the panel count goes up. Panel count is set by the width of your opening and by the maximum panel size the system you choose is rated for, so we work it out at the measure, not in advance.
Can a stacking door turn a corner?
Yes. Two runs can meet at a building corner with no post left standing between them when the door is open. It is the most demanding version structurally, because the load over the corner has to be carried by the beam above with nothing underneath it, so the door and the structure have to be designed together.
How wide does my opening need to be for a stacking door to make sense?
There is no hard minimum, but the extra tracks stop paying for themselves on a narrow opening. Below roughly eight feet a two or three panel slider gives you a similar result for a great deal less. Most of the stacking doors we install go into great room and patio openings, not into standard bedroom or dining sliders.
Do the open panels take up space on my patio?
No. Unlike a folding wall, nothing swings or folds outward. The panels stay in the plane of the wall and stack in front of each other at the jamb, so an outdoor kitchen, a seating area or a narrow walkway right outside the opening does not have to move. What the stack takes instead is part of the clear width of the opening.
Are large stacking panels hard to slide?
A correctly specified and correctly installed panel moves with light, steady hand pressure, however big it is. That depends on the roller carriages being rated for the finished weight of the panel with the glass and hardware included, and on the sill being set dead level. If a panel drags or needs a shove, that is a fault to fix, not something to live with.
Can a stacking door be power operated?
Some systems can. It is worth raising early on a tall or heavy run, because it changes the frame and brings electrical work with it. It is a specification decision made before the door is ordered, not an accessory you can add later.
What frame materials can I choose from?
Thermally broken aluminum, clad wood, and vinyl or composite. Aluminum is usually the strongest choice at large panel sizes and keeps the sightlines narrow. Clad wood gives a warmer interior face. Vinyl and composite cost less and suit shorter runs and smaller panels. Which one is right depends on your panel sizes and how much sun the opening takes.
Which aluminum stacking doors do you install, IWC or PRL?
Both, for different openings. For most homes we install IWC’s 8800 Series Ambassador multi-slide: aluminum panels up to 4 by 9 feet or 5 by 10 feet depending on the model, Low-E glass as standard, a choice of white, Mojave Beige, clear anodized or bronze anodized, and IWC’s lifetime limited warranty for single-family homeowners for as long as they own the home. It costs a little more than commercial aluminum. PRL Glass Systems builds commercially rated aluminum sliding systems, including stacking, pocket and corner layouts, and we use them where an opening calls for that heavier framing. Your quote names the brand, the series and the glass for each opening.
Which glass should I choose for a west-facing opening in Phoenix?
A spectrally selective low-E coating on a dual pane unit with argon is the usual starting point, because it cuts solar heat and ultraviolet light while keeping the room bright. Laminated glass is worth considering as well, since it blocks more ultraviolet light and cuts outside noise. Ask for the NFRC label for the exact configuration being quoted, not for the product line in general.
Can I have a flush threshold?
Often yes, and it is the easiest sill to walk and roll across. The tradeoff is that a flush sill holds back less water, so more of the work falls on the patio being laid to fall away from the opening and on the drainage around it. On a remodel it may also mean cutting the slab, which belongs in the quote as its own line.
Do I need a permit to install a stacking door in Phoenix?
If the door goes into the opening you already have, a like-for-like replacement is generally exempt. If we widen or heighten the opening, that is not ordinary repair, and it needs plan approval and inspection. Requirements vary by property and by city, and we confirm what yours needs at the first visit. We handle the permitting either way.
Will my wall need a new header?
If the opening is getting wider, yes. The existing beam is replaced with an engineered header sized for the new span and for whatever it carries above. That work is quoted from the engineering, not guessed at, and on most jobs it is the single biggest difference between two quotes that look similar on the door itself.
Can a stacking door be my home's required exit door?
Generally no. The required exit door has to be side hinged and give at least 32 inches of clear width and 78 inches of clear height. A sliding or stacking panel does not meet that, so another door in the house has to cover it. Most Phoenix homes already have a side hinged front, rear or garage entry door that does.
Can I put a screen on a stacking door?
Yes. Retractable screens that run in a cassette across the opening are the common answer, and some systems offer a screen panel on its own track. On a wide opening a screen is a real line item and not an accessory, so decide about it while the door is being specified.
How much does a stacking door cost in Phoenix?
We do not publish a per-door figure, because two openings of the same width can differ by a factor of three. The biggest single swing is whether the opening changes size. After that it is panel count and size, frame material and finish, the glass package, and the sill, screens and hardware. Your quote shows the door and the work on the opening as separate lines.
How do I keep the tracks working in Phoenix dust?
Vacuum the tracks out monthly through spring and fall and wipe them dry. Do not grease them, because grease holds the grit that causes the wear. Check the weep openings in the outer face of the sill are clear before monsoon season, and have any panel that starts to drag adjusted early.
Do you offer financing on a project like this?
Yes, on larger projects and subject to credit approval. The rate, the term and the lender depend on the plan you qualify for, so we go through the current options at your free in-home estimate and write the full terms into your quote before anything is signed.
