Begin With the Homeowner’s Actual Needs

“Aging in place” can mean different things. One homeowner may want easier access while carrying groceries. Another may use a walker, wheelchair, or mobility scooter. Someone with limited hand strength may be more concerned about panel and lock operation than opening width.

Ask how the opening is used today and how the homeowner expects to use it in the future. Avoid assuming a person’s needs based on age or appearance.

• Who will use the door?
• Will anyone use a wheelchair, walker, cane, or mobility scooter?
• Is independent operation an important goal?
• Is the exterior destination a deck, patio, balcony, yard, or stair?
• Is the door part of a required accessible route?
• Are there local code, housing-program, or project specifications?

Contractors can explore configurations through Suburban Wholesale Supply’s Gentek Sanctuary patio-door page.

Residential Convenience Is Not Automatically ADA Compliance

The Americans with Disabilities Act applies to specified facilities and circumstances. Many privately owned single-family homes are not governed by the ADA Standards, although other federal, state, local, housing, or project accessibility requirements may apply.

Even when ADA criteria are relevant, compliance is evaluated across the complete accessible route and installed opening. A patio door cannot be declared “ADA compliant” based on a brochure, nominal width, or threshold description alone.

Use precise language such as “selected to support the homeowner’s accessibility goals” unless a qualified project review establishes compliance with every applicable requirement.

Nominal Door Width Is Not Clear Opening Width

A patio door may be described by its overall frame or nominal size. The usable passage is smaller because portions of the frame, fixed panel, active panel, handles, and stops remain within the opening.

The 2010 ADA Standards generally reference a minimum clear width of 32 inches for door openings, measured with the door open 90 degrees. Sliding-door geometry differs from hinged-door geometry, so the actual clear opening must be confirmed using the applicable standard and the exact product configuration.

Before ordering, request or measure the clear-opening dimension for the exact Sanctuary size, style, panel configuration, and operating arrangement. Do not calculate it by simply dividing the overall width by two.

Compare Two-, Three-, and Four-Panel Configurations

Gentek Sanctuary patio doors are offered in two-, three-, and four-panel configurations. A larger overall assembly may offer design flexibility, but panel count alone does not establish the clear passage.

Confirm current Gentek configuration details rather than assuming every multi-panel door operates the same way.

Threshold Height Is Only Part of the Transition

Accessibility standards address changes in level and threshold conditions, but a successful transition also depends on interior flooring, exterior landing height, sill shape, drainage, snow exposure, flashing, and water management.

The ADA Standards generally limit thresholds at doorways to one-half inch, with limited exceptions and requirements for beveled changes in level. Existing or altered conditions can involve additional provisions. The exact project requirements must be verified rather than quoted from memory.

Evaluate the complete path:

• Interior finished-floor elevation
• Patio-door sill height and profile
• Exterior deck, landing, or patio elevation
• Transitions, mats, rugs, and floor coverings
• Required water drainage and flashing space
• Snow, ice, and wind-driven-rain exposure
• Structural support beneath the sill
• Applicable code and accessibility requirements

Do not bury, cut, or alter an engineered sill to create a lower transition unless Gentek specifically authorizes the detail. Reducing threshold height by compromising drainage or structural support is not an acceptable accessibility solution.

Exterior Landings Must Be Part of the Plan

A low interior transition provides limited value if the exterior route ends at a step, narrow landing, unstable surface, steep slope, or door-side obstruction.

• Confirm adequate landing size and stability.
• Check cross slope and running slope where accessibility rules apply.
• Provide drainage away from the building without creating an abrupt edge.
• Account for railings, grills, furniture, planters, and screen operation.
• Plan snow and ice removal without blocking door drainage.
• Coordinate deck elevation with flashing and cladding clearances.

Raising a deck or patio close to the sill can improve the transition while increasing water exposure. The design must preserve a reliable drainage and flashing strategy.

Operating Force Must Be Evaluated After Installation

Sliding doors can be attractive for aging-in-place projects because they do not require the user to move around a swinging panel. However, the operating panel must still be moved along its track and brought fully into the locking position.

Product size, glass weight, roller condition, track cleanliness, frame alignment, weatherstripping contact, temperature, and installation quality can all influence perceived effort.

If a new door feels unusually difficult to operate, check:

• Debris or protective material left in the track
• Sill level and continuous support
• Frame square, plumb, and jamb dimensions
• Roller adjustment performed according to Gentek instructions
• Weatherstripping and interlock alignment
• Lock and keeper position
• Excessive insulation pressure bowing the frame

Do not promise a particular operating-force value unless it has been verified for the exact installed product under the applicable test or project requirements.

Handle and Lock Usability Matter

A panel that slides smoothly may still be difficult for someone with limited grip strength, dexterity, reach, or balance if the handle and lock are not comfortable to use.

Gentek states that Contemporary and Classic Sanctuary doors use a handle with a thumb latch, while the French-style handle incorporates a top lock for added resistance. The homeowner should operate a physical sample or demonstration unit whenever accessibility is a significant concern.

• Can the homeowner grasp the handle securely?
• Can the thumb latch or lock be operated without painful force?
• Can the user reach the hardware from a seated position?
• Does locking require pushing or lifting the panel?
• Will curtains, blinds, or furniture obstruct the handle?
• Is exterior key access needed for the intended route?

Do not assume that a familiar handle shape works for every user. Direct demonstration is more reliable than a photograph.

Approach and Maneuvering Space

Users need enough clear floor or ground space to approach, operate, and pass through the door. Required dimensions depend on the governing standard, direction of approach, hardware, and surrounding route.

• Keep furniture away from the operating panel and handle.
• Account for curtains and window treatments.
• Provide a stable, slip-resistant interior approach.
• Avoid loose rugs that create a secondary threshold.
• Keep exterior furniture and planters away from the passage.
• Ensure the screen does not create an unexpected obstacle.

Sliding doors eliminate a swinging-door arc, but that does not eliminate maneuvering-space requirements where accessibility standards apply.

Screens Can Complicate an Accessible Route

A sliding insect screen introduces a second panel, handle, track, and sill transition. Confirm that the intended user can operate both the screen and patio door independently.

A screen is intended primarily to reduce insect entry. It is not a fall guard, security barrier, hand support, or substitute for a code-compliant guardrail. Users should not lean against it while crossing the threshold.

Integrated Mini Blinds May Reduce Reach and Cleaning Demands

Gentek offers integrated mini blinds sealed within the insulated-glass unit. The design can eliminate hanging cords and reduce ordinary dust accumulation on the blind.

That can be a useful convenience, but the external operator must still be within comfortable reach and move without binding. Ask the homeowner to test the control on a demonstration product when possible.

Integrated blinds should not be described as accessible for every person without evaluating the operator’s location, travel, required motion, and the user’s abilities.

Accessibility Cannot Override Water Management

Patio-door sills are exposed to rain, melting snow, cleaning water, and exterior surface drainage. Lowering the transition can increase water management challenges.

• Provide continuous structural support beneath the sill.
• Use a compatible sill-pan and flashing strategy where required.
• Preserve the door’s intended drainage openings.
• Slope exterior surfaces appropriately without creating access barriers.
• Coordinate deck membranes, masonry, stucco, and cladding details.
• Do not bridge or block the sill with unauthorized ramps or sealant.

A portable or permanent threshold ramp must be evaluated for stability, slope, interference with door operation, drainage, and applicable safety requirements. It should not simply be placed over drainage openings.

Aging-in-Place Planning Checklist

1. Identify the homeowner’s present and anticipated mobility needs.
2. Determine which accessibility codes or project standards apply.
3. Verify the exact clear opening—not merely nominal door width.
4. Compare available two-, three-, and four-panel configurations.
5. Confirm the active panel and traffic path.
6. Evaluate the interior and exterior approach space.
7. Measure the complete finished threshold transition.
8. Coordinate sill support, flashing, drainage, and exterior elevation.
9. Have the homeowner test representative handle and lock operation.
10. Evaluate screen and integrated-blind controls.
11. Verify panel operation after installation and adjustment.
12. Document final dimensions and homeowner instructions.

Common Sales Mistakes

Better Sales Tips for Contractors

Use needs-based language

Ask what movements are difficult and what route the homeowner wants to use. Then connect product and installation decisions to those needs.

Provide verified dimensions

Put the expected clear opening and finished transition on the proposal when they are important. Identify whether those figures are manufacturer data, field measurements, or design targets.

Demonstrate the hardware

A showroom or product demonstration lets the homeowner assess handle, lock, screen, and integrated-blind operation before ordering.

Bring in the right professional

Projects involving formal accessibility compliance, structural changes, ramps, elevated decks, or complex water management may require an architect, designer, occupational therapist, code official, or other qualified professional.

What AAMA Gold Label Certification Means Here

FGIA explains that the AAMA Gold Label provides third-party verification of fenestration-product performance. A representative sample is independently tested, and ongoing manufacturing inspections help verify continued compliance with applicable requirements.

The Gold Label is not an accessibility certification. It does not establish the installed clear opening, threshold transition, approach space, operating force, or compliance of the complete route.

What InstallationMasters Contributes

FGIA’s InstallationMasters program covers accepted practices for residential and light-commercial window and exterior glass-door installation. Subjects extend from initial site inspection through final cleaning and maintenance.

Site inspection and opening preparation are especially important when the finished threshold and route must support accessibility goals. FGIA also states that the product manufacturer’s instructions take precedence.

InstallationMasters certification should not be represented as an ADA credential or proof that an individual project complies with accessibility law.
