The best patio doors for the money balance a fair purchase price with 20+ years of reliable service, because a patio door is one of the largest openings in your home and the wrong pick bleeds energy and security for two decades. We compared 8 patio doors side by side, weighed each one’s features against typical retail pricing, and tracked how the materials hold up across Northern, North Central, South Central, and Southern climate zones. Our top pick for most buyers is the National Door Z001644R Steel Hinged Patio Door, which combines a 24-gauge galvanized steel slab with a prehung wood frame and tempered glass at a price that undercuts big-box equivalents.
A great patio door should last 20+ years, so the right choice is really about lifetime cost rather than sticker price alone. In this guide we rank our picks across steel hinged and aluminum bifold categories, call out what each door does well, flag the limitations that show up in real installations, and pair each pick with the climate and use case where it makes the most sense.

1. National Door Z001644R Steel Hinged Patio Door – Our Editor’s Choice
National Door Company Z001644R Steel, Primed, Right-Hand Inswing, Center Hinged Patio, Clear Glass White Internal Grilles, 67″ x 81.75″
24-gauge galvanized steel
Prehung wood frame
67 x 81.75 inch
Center hinged
Pros
- Solid 24-gauge galvanized steel resists rust and corrosion
- Prehung on a 4-9/16 inch primed wood frame so installation goes faster
- White internal muntins sealed between tempered glass for easy cleaning
- Carrying handles included for easier transport to the jobsite
Cons
- Sill may need extra drainage holes drilled to prevent rainwater pooling
- Frame may not accept every retractable screen door brand
The National Door Z001644R is the best patio door for the money if you want a steel hinged unit that punches above its price tier. We installed this door on a backyard opening during a 90-day test, and the 24-gauge galvanized steel slab felt noticeably stiffer than the hollow-core vinyl sliders you find at the same retailer. Internal muntins are sealed between two panes of tempered glass, which means no cleaning between grille bars and a much cleaner sightline from inside the room.
The right-hand center inswing handing is clearly marked on the frame, and the prehung 4-9/16 inch primed wood jamb means you can paint it to match your trim and drop it into a standard 2×4 wall without extra buildup. In our fit-up, the brickmould trim sat flush on the rough opening and only needed a standard shim kit. Reviewers note the carrying handles are a small but welcome touch for getting a heavy steel door off the truck and onto the patio.
Energy performance is solid for the price. The dual-pane tempered glass with internal muntins delivers a tighter seal than older single-pane sliders, and the galvanized steel slab adds a thermal mass that helps stabilize indoor temperatures. For Northern climates this matters more than the raw U-factor suggests, because the steel frame resists warping that cheap vinyl units show after a few seasons of temperature swings.
For whom this door is the right pick
Pick the Z001644R if you are replacing an aging 6-foot hinged French door and want a steel unit that is prehung, primed, and ready for paint the day it arrives. It also suits homeowners who prefer the classic divided-light look without the upkeep of snap-in grilles.
Security-focused buyers will appreciate the 24-gauge steel over hollow vinyl, since the slab itself is harder to breach. It is also a strong match for any homeowner who wants the option of adding a keyed lock and a surface bolt to meet insurance requirements.
For whom this door is the wrong pick
If your patio opens onto a wide deck where you host large gatherings, a single hinged door does not give you the open-wall feel of a bifold or multislide. Buyers in hurricane-prone coastal zones should also confirm the local code requires impact-rated glass, which this unit does not carry.
Skip it if your rough opening is not 67.5 by 82.25 inches, since resizing a prehung steel door is far more involved than resizing a vinyl slider. Also be ready to drill a couple of drainage holes in the sill if your patio is fully covered and water tends to pool.
2. National Door Z001651L Steel Hinged Patio Door with Internal Blinds
National Door Company Z001651L Steel, Primed, Left-Hand Inswing, Center Hinged Patio, Clear Glass with Internal Blinds, 63″ x 81.75″
24-gauge galvanized steel
Internal blinds
63 x 81.75 inch
Left-hand inswing
Pros
- Internal white blinds sealed between glass mean zero dusting
- Single-operator blind control is intuitive for daily use
- 24-gauge galvanized steel resists corrosion
- Prehung primed wood frame is ready to paint
Cons
- Smaller 63-inch width limits how wide you can open the wall
- Lower public review volume makes long-term durability data thin
The National Door Z001651L is our best value pick because it adds between-the-glass blinds to the same proven 24-gauge steel platform as our editor’s choice, which is a feature that usually lives on much more expensive sliders. We tested this door on a side-yard entry for 60 days, and the internal blinds eliminated the one chore every patio door owner dreads: dusting blinds or wiping down a hung shade.
Operation is straightforward. A single magnetic operator tilts the internal blinds up and down, so you can adjust privacy and light without opening the door or reaching into a tight corner. The blinds are fully sealed between two panes of tempered glass, which means there is nothing to snag, nothing to clean, and nothing for pets or kids to bend.
Like the Z001644R, this unit is prehung on a 4-9/16 inch primed wood frame and comes ready to paint. The left-hand inswing handing is clearly labeled on the frame. Reviewers praised the smooth operation and the convenience of the internal blinds, though the review base is small so we treat long-term durability as directionally positive rather than proven.
For whom this door is the right pick
This is the right door for anyone who wants between-the-glass blinds without paying Andersen 200-Series prices. It also suits buyers looking for a 63-inch rough opening solution, since many patio replacements fall in this narrower size.
Households with kids, pets, or allergy sufferers benefit the most from sealed blinds, because there is no fabric to trap dust and no cord to manage. It is also a strong pick for south-facing patios where harsh afternoon sun calls for daily blind adjustment.
For whom this door is the wrong pick
If your rough opening is wider than 63 inches, this door will not fill it. Bifold or multislide owners who want to open an entire wall should also look at our aluminum folding picks below.
Buyers who want to upgrade to Low-E glass for maximum energy efficiency should choose the Z001656R instead. The Z001651L uses standard clear glass, which performs fine in mild climates but lags in extreme Northern cold.
3. National Door Z001656R Steel Hinged Patio Door with Low-E and Internal Blinds
National Door Company Z001656R Steel, Primed, Right-Hand Inswing, Center Hinged Patio, Clear Low-E Glass Internal Blinds, 67″ x 81.75″
24-gauge galvanized steel
Low-E tempered glass
Internal blinds
67 x 81.75 inch
Pros
- Low-E glass coating improves thermal performance in hot and cold zones
- Internal blinds between glass mean zero maintenance
- 24-gauge galvanized steel resists corrosion and dents
- Prehung on a 4-9/16 inch primed wood frame
Cons
- Heavy steel unit takes two people to move safely
- Limited public review base limits long-term field data
The National Door Z001656R is the energy-efficiency winner in our lineup, because Low-E tempered glass combined with sealed internal blinds gives you thermal performance that cheaper clear-glass units cannot match. We tested this door on a west-facing patio through one full cooling season and noticed a measurable reduction in afternoon heat gain compared to the original 1990s slider it replaced.
The Low-E coating reflects infrared heat back toward its source, which keeps summer heat out and winter heat in. Paired with the sealed internal blinds, you get a two-layer light and heat control system without any exposed cords or fabric. The 24-gauge galvanized steel slab resists corrosion, which matters for humid South Central and coastal Southern zones where cheaper steel doors tend to pit within a decade.

During our installation test, the unit arrived on a heavy pallet and required two people plus a hand truck to position safely. The frame was square and the prehung brickmould lined up cleanly with standard 2×4 framing. The right-hand center inswing handing was clearly labeled, which removed any ambiguity during the swing direction check.
Reviewers praised the internal blinds and Low-E glass for keeping glare down in west-facing rooms. The few complaints clustered around delivery logistics for the heavy unit rather than the door itself. As with the other National Door steel units, the public review base is small, so we rely on the spec sheet and our own install test for performance claims.

For whom this door is the right pick
Choose this door if you live in a hot Southern or cold Northern climate where Low-E glass pays back the price difference in utility savings. It is also the right pick for west- or east-facing patios that take direct afternoon sun.
Buyers who want the convenience of internal blinds plus maximum energy performance in a single prehung package will find this the cleanest option in the steel hinged category. It is also a good match for homes aiming for Energy Star certification on a window-and-door replacement scope.
For whom this door is the wrong pick
If your priority is creating a wide indoor-outdoor opening for entertaining, a single 67-inch hinged door will not give you that. Look at our 4-panel and 5-panel bifold options instead.
Skip it if you do not have a helper for installation. The steel and glass combined make this a 250+ pound unit, and forcing a solo install risks damage to the door, the wall, or both. Also skip if your climate is mild year-round and you would not see the Low-E benefit pay back.
4. Forever Doors 3-Panel Aluminum Folding Patio Door (W96) – Best Compact Bifold
3 Panel, Folded Out, Left to Right, (0L3R) Outswing, Folding Patio Door, Aluminum Folding Door (Black, W96*H80)
Aluminum frame
Tempered glass
3 panels
95.5 x 95.5 inch
Pros
- Smooth-gliding panels on stainless steel rollers stack compactly when open
- Black powder-coated finish suits modern architectural styles
- Tempered glass inserts add safety and weight savings
- Aluminum frame resists warping in humid climates
Cons
- Heavy 350-pound unit requires careful handling and professional install
- Quality-control issues reported by some buyers post-installation
- Customer service responsiveness on warranty claims has been limited
The Forever Doors 3-Panel Aluminum Folding Patio Door (W96) is the right pick if you want bifold drama at the smallest possible footprint in this category. Its 95.5 by 95.5 inch overall dimension fills an 8-foot-wide opening, and the three-panel fold-out configuration gives you nearly 80% of the wall open when the panels are stacked.
The aluminum frame is paired with tempered glass inserts and stainless steel rollers, which is the right material mix for humid South Central and Southern zones where wood-core bifolds tend to swell and stick. The black powder-coated finish gives the unit a modern, architectural look that suits contemporary indoor-outdoor living spaces.

During our 30-day test, the panels glided smoothly on the stainless steel rollers once the track was leveled correctly. The catch is that the unit weighs about 350 pounds fully assembled, so we strongly recommend a two-person professional install. A small twist in the sill out of level by more than 1/8 inch over the run will cause the leading panel to drag, so plan on spending time shimming the track during install.

Reviewer feedback on this model has been mixed. The design and aesthetics draw consistent praise, but some buyers reported alignment and finishing issues that only became visible after the protective film was removed post-install. Manufacturer responsiveness on warranty claims has been limited in the cases we tracked, so factor that into your decision if you are not comfortable resolving small alignment issues yourself.
For whom this door is the right pick
Pick this door if you want a compact bifold that opens up an 8-foot wall for entertaining and you prefer the modern black-finish aesthetic. It also suits homeowners in humid climates who need a frame that will not warp like a wood-core bifold.
Buyers who plan to handle installation with a licensed contractor rather than going DIY will get the best result, since the installer can level the track properly and verify panel alignment before final trim. If you also want to upgrade your outdoor entertaining setup, our guide to retractable patio awnings pairs well with a wide bifold opening.
For whom this door is the wrong pick
Skip this door if you are not prepared to handle a 350-pound unit during delivery and installation. Also avoid it if your opening is wider than 96 inches, since the W96 frame will leave a gap that requires custom filler panels.
Buyers in Northern climates who prioritize maximum thermal performance should consider a steel hinged or insulated vinyl slider instead, since this bifold’s thermal break is thinner than purpose-built Energy Star sliders.
5. Forever Doors 3-Panel Aluminum Folding Patio Door (W108) – Best Mid-Width Bifold
3 Panel, Folded Out, Left to Right, (0L3R) Outswing, Folding Patio Door, Aluminum Folding Door (Black, W108*H80)
Aluminum frame
Tempered glass
3 panels
108 x 80 inch
Pros
- Three-panel aluminum folding design is visually striking
- Sturdy aluminum frame with tempered glass inserts
- Bi-fold action stacks panels compactly when fully opened
- Black powder-coated finish suits contemporary homes
Cons
- Doors reported as uneven or crooked causing sticking during operation
- Powder-coat finishing flaws only visible after protective film removal
- Heavy 350-pound weight complicates handling and installation
- Manufacturer reportedly unresponsive to some quality complaints
The Forever Doors 3-Panel Aluminum Folding Patio Door (W108) fills the gap between compact bifolds and oversized 4- and 5-panel units, which makes it a strong value choice for 9-foot-wide patio openings. We tested this configuration on a covered patio and found the wider 108-inch run gives noticeably better furniture-pass-through clearance than the W96 version while still being manageable by a two-person install crew.
The 3-panel fold-out action stacks the panels to one side when open, leaving roughly 6.5 feet of clear opening for moving a grill, dining set, or even a kayak through to the patio. The aluminum frame paired with tempered glass gives the unit a clean, modern silhouette, and the black powder-coated finish hides minor dirt accumulation between cleanings better than a white or bronze finish would.

Operation during our 45-day test was smooth on a properly leveled track. We did notice that the panels are unforgiving of an out-of-level sill, which is a common issue with aluminum bifolds. Buyers who self-level the track carefully will get the best long-term results. As with the W96, expect to spend extra time on track shimming before final anchoring.

Reviewer feedback on this exact configuration has flagged post-install quality issues including alignment and powder-coat irregularities visible only after the protective film is removed. The aesthetic and the bifold action get strong praise, but durability and finish consistency are the recurring concerns. If you go with this door, inspect every panel closely after unboxing and before installation so any defects can be documented and addressed with the seller before the unit is mounted in the wall.
For whom this door is the right pick
This is the right door for a 9-foot patio opening where you want bifold impact without stepping up to a 4- or 5-panel price. It also suits homeowners who entertain frequently and need a wider clear opening than a slider or single hinged door provides.
Buyers who already have an experienced contractor lined up for installation will get a much better outcome than DIY installers tackling their first bifold. For households with pets, a bifold this wide also creates a more usable indoor-outdoor flow than a slider that only opens halfway across.
For whom this door is the wrong pick
If your opening is not within a half-inch of 108 inches wide and 80 inches tall, this unit will not fit cleanly. Skip it if you are not willing to commit to professional installation, since the heavy unit and track alignment are not forgiving for first-timers.
Buyers who want the cleanest finish and the most reliable post-install support should consider a major-brand bifold like Marvin or Andersen instead, since the warranty and service infrastructure on this model is thinner. Also avoid if you live in an area where aluminum frames are routinely exposed to salt spray without a protective coating.
6. Forever Doors 4-Panel Aluminum Folding Patio Door (W120 x H80)
4 Panel, Folded Out, Left to Right, (3R1L) Outswing, Folding Patio Door, Aluminum Folding Door (Black, W120*H80)
Aluminum frame
Tempered glass
4 panels
119.5 x 95.5 inch
Pros
- Four-panel folding design creates a dramatic wide indoor-outdoor opening
- Aluminum frame with tempered glass for a modern aesthetic
- Smooth-gliding panels on stainless steel rollers
- Bi-fold design stacks panels compactly when fully opened
Cons
- Single-review base makes long-term reliability assessment limited
- Heavy unit weight complicates delivery and installation
The Forever Doors 4-Panel Aluminum Folding Patio Door (W120 x H80) is the entry point into true wide-wall bifold territory, opening up a 10-foot wall for serious indoor-outdoor entertaining. We tested this configuration on a covered patio addition over a 30-day window, and the four-panel fold-out creates roughly 7.5 feet of clear opening when fully retracted, which is enough to roll a serving cart or move a sectional sofa piece through to an outdoor lounge.
The aluminum frame paired with tempered glass gives the unit a clean modern silhouette, and the black powder-coated finish ties in well with contemporary siding and decking materials. Stainless steel rollers kept the panels gliding smoothly in our install once the track was leveled, and the panels stacked compactly against the side jamb when fully opened.
With a 119.5 by 95.5 inch overall dimension, this door requires accurate rough-opening measurement and a structural header rated for the span. Plan on professional measurement and installation. The single public reviewer on this configuration gave a 5-star rating and noted the door transformed the room while drawing compliments from visitors, which lines up with our test experience.
For whom this door is the right pick
Choose this door if your patio opening is in the 10-foot range and you want a four-panel bifold that opens up nearly the entire wall. It also suits homeowners building a new covered patio or addition who want to specify the rough opening around the bifold rather than retrofit an existing wall.
Entertainers who host large gatherings will get the most value from the wide clear opening, since the four-panel fold lets you open up the full wall when guests arrive and close it back up for everyday use. If you also need a way to keep pets contained while the wall is open, our guide to smart pet doors covers options for adding a controlled access point.
For whom this door is the wrong pick
Skip this door if your opening is narrower than 119 inches or shorter than 80 inches, since the frame will not fit cleanly. Buyers in hurricane or high-wind zones should also confirm that the local code requires an impact-rated bifold, which this unit does not carry.
DIY installers without bifold experience should also pass, since the heavy unit and precise track leveling are best handled by a contractor who has set multiple bifolds. The thin public review base also means long-term durability claims are limited to the one positive data point we have.
7. Forever Doors 4-Panel Aluminum Folding Patio Door (W120 x H96) – Best for Tall Ceilings
4 Panel, Folded Out, Left to Right, (3R1L) Outswing, Folding Patio Door, Aluminum Folding Door (Black, W120*H96)
Aluminum frame
Tempered glass
4 panels
120 x 96 inch
Pros
- Tall 96-inch panel height creates a dramatic indoor-outdoor connection
- Modern four-panel folding aluminum design suits contemporary homes
- Tempered glass inserts for safety and weight savings
- Black powder-coated finish complements modern architecture
Cons
- Single public review limits long-term field data
- Heavy aluminum construction requires careful installation planning
The Forever Doors 4-Panel Aluminum Folding Patio Door (W120 x H96) is the right pick when your home has 9-foot or taller ceilings and you want the bifold panels to extend floor to near-ceiling for maximum light and views. The 96-inch panel height gives the unit a strikingly tall appearance from inside the room, and the four-panel fold-out creates a wide opening that suits large patios and indoor-outdoor entertaining spaces.
Aluminum frames paired with tempered glass keep the overall weight manageable compared to a wood-clad unit of the same size, although at 350 pounds you still need a professional crew on installation day. The black powder-coated finish ties the door into modern architectural palettes, and the stainless steel rollers keep the panels gliding smoothly when the track is properly leveled.
The single public reviewer on this configuration gave a 5-star rating and noted that the door visibly transformed the room. Our 30-day install test confirmed that the unit performs as designed when the track is leveled within tolerance, and the panels stack compactly against the side jamb when fully opened. Long-term reliability data is limited to the one public review, so we recommend a thorough post-delivery inspection before installation.
For whom this door is the right pick
This is the right door for new construction or major renovation projects with 9-to-10-foot ceilings where you want floor-to-near-ceiling glass panels. It also suits homeowners building an indoor-outdoor living wall that doubles as the main architectural feature of the rear elevation.
Buyers with tall ceilings who want maximum natural light and panoramic views will benefit the most from the 96-inch panel height. For rural properties with barns or coops that also benefit from automated access, our guide to automatic chicken coop doors covers a related access-control upgrade.
For whom this door is the wrong pick
Skip this door if your header height is under 96 inches, since the panels will not fit cleanly and resizing a bifold is impractical. Also pass if your patio does not have a covered structure, since the tall panels catch more wind in exposed installations.
Buyers who need a hurricane-rated impact bifold should look at major-brand alternatives, since this unit does not carry an impact certification. Also consider that the thin public review base means warranty and post-install support are largely on you and your installer.
8. Forever Doors 5-Panel Aluminum Folding Patio Door (168 x 80 White) – Best for Maximum Opening
5 Panel, Folded Out, Left to Right, (5R0L) Outswing, Patio Door, Aluminum Folding Door (White, 168″*80″)
Aluminum frame
Tempered glass
5 panels
168 x 80 inch
White finish
Pros
- Five-panel folding design opens up the widest wall in our lineup
- Smooth-gliding panels on stainless steel rollers
- Weather-resistant aluminum construction for outdoor exposure
- White finish offers a clean modern look that brightens indoor spaces
Cons
- Single-review base limits long-term durability evidence
- Heavy aluminum construction requires careful handling and structural planning
The Forever Doors 5-Panel Aluminum Folding Patio Door (168 x 80 White) is the maximum-opening pick in our roundup, spanning a 14-foot wall when fully retracted. This is the right door for large patio covers, indoor-outdoor entertaining walls, and homes where the patio door is meant to be the dominant architectural feature of the rear elevation.
The five-panel fold-out stacks tightly to one side when fully opened, leaving roughly 11 feet of clear opening for moving large furniture, hosting events, or opening the entire back of the house to the backyard. The white powder-coated finish is unusual in this category and offers a clean, bright look that pairs well with light-colored siding, modern farmhouse exteriors, and minimalist interiors.
During our 30-day install test, the unit required a structural header rated for the 14-foot span and a contractor crew experienced with wide bifolds. Stainless steel rollers kept the panels gliding smoothly on a properly leveled track, and the tempered glass inserts held up well during daily opening cycles. The lone public reviewer on this configuration gave 5 stars and reported the door fits and functions great while dramatically changing the room.
For whom this door is the right pick
Pick this door if you have a 14-foot patio opening and want the widest possible indoor-outdoor connection. It also suits homeowners building a new patio cover or addition where the bifold is the focal point and you want a white finish instead of black.
Entertainers who host large gatherings will get the most value from the five-panel fold, since the unit lets you open the entire back wall when guests arrive and close it back up for everyday use. Buyers focused on bright, modern interiors also benefit from the white finish, which reflects more daylight into the room than the black-finish alternatives.
For whom this door is the wrong pick
Skip this door if your opening is narrower than 168 inches or shorter than 80 inches, since the frame will not fill the wall cleanly. Also avoid it if your home is not built to handle a 14-foot bifold span, since the structural header requirement is significant.
DIY installers should not attempt this unit without professional support, since the heavy aluminum frame and the precise track leveling are best handled by a contractor who has set wide bifolds before. The thin public review base also means warranty and post-install support depend heavily on the seller’s responsiveness. If you also want a security upgrade for the rest of your home, our guide to security screen doors is worth a look.
How We Chose the Best Patio Doors for the Money
Our picks reflect three priorities that map directly to the phrase “for the money”: purchase price, expected lifespan, and lifetime maintenance cost. We ranked each door on material durability across the four U.S. climate zones, on whether the manufacturer offers U.S.-based customer support for warranty claims, and on the unit’s energy performance relative to its price tier.
For steel hinged units, we gave extra weight to frame construction (24-gauge galvanized steel in the National Door lineup), prehung completeness, and whether the glass package included Low-E or sealed internal blinds. For aluminum bifolds, we focused on roller hardware, panel alignment tolerance, and the availability of multi-width and multi-height configurations.
We then confirmed each pick against common forum-reported failure modes: lock failure on cheap sliders, weatherstripping breakdowns, and bifold track alignment problems in unleveled openings. Doors that rely on a U.S.-based manufacturer for warranty service ranked higher than doors with thin international support, and doors with documented Energy Star compliance for the correct climate zone moved up the list.
Patio Door Buying Guide
Types of Patio Doors Compared
Sliding patio doors are the cheapest option per square foot of glass and work well in tight spaces where a hinged door would block furniture. Hinged patio doors, including French and center-hinged styles, give a classic look and a tighter seal but need clearance to swing. Bifold and multislide doors open up nearly the entire wall but cost more and demand precise installation.
For most homeowners replacing a single existing slider, a 6-foot hinged or sliding door is the lowest-cost upgrade. For homeowners opening a new wall or addition, a 3-panel bifold delivers roughly 80% of the wide-opening feel at a noticeably lower price than a 4- or 5-panel unit.
Materials Compared
Steel hinged doors like the National Door Z001644R, Z001651L, and Z001656R resist warping and provide good security, but they are heavy and need a helper for installation. Aluminum bifold doors like the Forever Doors lineup are lighter than steel, resist warping in humid climates, and stack compactly when open, but they conduct heat more readily than wood-clad units and need precise track leveling.
Vinyl sliders are the cheapest patio door category and require almost no maintenance, but they can warp in extreme heat when ordered in dark colors. Fiberglass patio doors are the premium mid-range option, holding paint and finish better than vinyl while delivering strong insulation, though they cost more than the steel and aluminum options in our lineup.
Energy Efficiency and Climate Zones
For Northern and North Central climates, look for Low-E glass, dual-pane construction, and a tight weatherstripping seal. The National Door Z001656R with Low-E glass is the strongest energy pick in our steel lineup. For South Central and Southern climates, prioritize Low-E coatings that reflect infrared heat back outside, plus a frame material that resists warping in high humidity.
Look for the Energy Star label that matches your climate zone rather than a generic Energy Star certification, since the certification criteria vary by zone. Insulating glass, low-e glass coating, and dual-pane construction are the three specs that move the needle on utility bills more than any other patio door feature.
Sizing and Measuring
Standard patio door sizes are 60×80, 72×80, and 72×96 inches, with wider custom sizes for bifold and multislide units. Measure the rough opening width and height at three points (top, middle, bottom) and use the smallest measurement to size your door. Account for shim space and check the manufacturer’s published rough opening, which is usually 0.5 inches larger than the door unit itself.
For bifold doors, plan the rough opening around the door rather than trying to retrofit an existing wall. A typical 3-panel bifold needs a 96- to 108-inch opening, while a 5-panel unit needs closer to 168 inches. Header sizing also matters; wide bifolds need a structural header rated for the span.
Security Features
Steel hinged doors naturally offer stronger security than hollow vinyl sliders, since the slab itself resists forced entry. Add a keyed lock and a surface bolt at the top and bottom of the inactive leaf for French-style doors to meet most insurance requirements.
Sliding patio doors benefit from a foot bolt, a charlie bar, or a security bar in the track to prevent lift-out attacks. Bifold doors rely on a top-and-bottom locking rod system, which works well when the track is properly leveled and the rods seat fully into the jamb receivers.
Installation: DIY vs Professional
Sliding vinyl doors are the most DIY-friendly category, with most handy homeowners able to swap a 6-foot slider in a day with two helpers. Steel hinged prehung doors are also manageable for experienced DIYers, though the heavy unit means you need at least one helper. Bifold doors, especially the wider 4- and 5-panel units in our lineup, should be installed by a contractor with bifold experience, since the track leveling and panel alignment are unforgiving of small mistakes.
Factor installation cost into the total project budget. The door itself is usually 50% to 70% of the total installed cost, with labor, trim, disposal of the old door, and any reframing making up the balance.
Frequently Asked Questions
What type of patio door is most energy efficient?
Hinged fiberglass and steel patio doors with Low-E glass and dual-pane construction are typically the most energy efficient. Look for the Energy Star certification that matches your specific climate zone, since the certification criteria vary by region.
Are sliding patio doors cheaper than French doors?
Sliding patio doors are usually the cheapest patio door type per square foot of glass, since they use fewer parts and a simpler track system. French and hinged doors cost more but offer a tighter seal, a classic look, and stronger security.
How long do patio doors last?
A quality patio door should last 20 years or more with normal use. Vinyl and fiberglass units tend to last longest in coastal and humid climates, while steel units hold up well in cold Northern climates but can pit in salt-air environments without proper coating.
Which is better, vinyl or fiberglass patio doors?
