| Selection |
Space efficiency |
No swing arc is required |
Sliding panels can preserve circulation space beside the opening and are useful where furniture, corridors, balconies, or equipment limit the available swing area. |
Coordinate the panel travel zone, stacking pocket, furniture layout, and emergency egress path before confirming the opening size. |
| Selection |
Clear opening for accessibility |
At least 813 mm clear width where a 32-inch accessible opening is required |
Door leaf size is not the same as usable clear opening. Frames, seals, handles, and overlapping panels can reduce the effective passage width. |
Measure the clear passage with the door fully open and verify the requirement under the governing local accessibility code. In the United States, confirm applicable ADA criteria. |
| Selection |
Operating force |
Target low opening force; verify the adopted accessibility standard |
Large or poorly adjusted panels can be difficult to operate, especially for children, older users, and people with limited mobility. |
Specify correctly sized rollers, level tracks, suitable handles, and an acceptance test for opening and closing force after installation. |
| Selection |
Threshold and floor transition |
Keep the threshold as low and flush as permitted; ADA doors generally limit thresholds to 13 mm (1/2 inch) |
Threshold height affects wheelchair access, trip safety, water management, and the connection between interior and exterior finishes. |
Coordinate threshold height with waterproofing, drainage, floor build-up, insulation, and the local accessibility code before construction. |
| Selection |
Glazing safety |
Use safety glazing where required; common verification routes include ANSI Z97.1, CPSC 16 CFR 1201, or EN 12600 |
Large glazed panels create a human-impact risk. The correct safety classification depends on location, pane size, door type, and jurisdiction. |
Mark safety glass permanently where required and specify laminated or tempered glass according to the hazard, security, acoustic, and thermal objectives. |
| Selection |
Thermal performance |
Evaluate whole-door U-value, solar heat gain, air leakage, and condensation risk |
Glass area, frame material, spacer design, seals, orientation, and climate zone can have a greater effect than the center-of-glass value alone. |
Request tested or calculated whole-product data in the units used by the project region, such as W/m²·K or Btu/h·ft²·°F. |
| Selection |
Weather resistance |
Specify project-required air, water, and structural performance ratings |
Wind, driving rain, humidity, salt exposure, and temperature ranges differ significantly between coastal, tropical, desert, and cold regions. |
Use site wind calculations and the relevant regional test method. Do not assume that a residential rating is suitable for a high-rise, exposed, or commercial application. |
| Selection |
Security and impact resistance |
Assess locking points, anti-lift protection, laminated glass, and frame anchorage |
Sliding doors can be vulnerable if panels can be lifted from the track or if the locking system is not matched to the frame and hardware. |
Specify tested hardware, anti-lift blocks, positive interlocks, secure keepers, and appropriate laminated glazing where security is a design priority. |
| Selection |
Acoustic control |
Set a project-specific acoustic target, such as laboratory Rw or STC, where applicable |
Acoustic performance depends on the complete assembly, perimeter seals, frame junctions, glass make-up, and installation quality. |
Request test data for the full door assembly rather than relying only on the glass specification. Seal all perimeter interfaces continuously. |
| Selection |
Material and corrosion environment |
Match finishes and fasteners to exposure conditions |
Salt air, de-icing chemicals, industrial pollutants, and persistent humidity can accelerate corrosion and shorten hardware life. |
Confirm alloy, coating, stainless-steel grade, drainage design, and compatibility between dissimilar metals before procurement. |
| Installation |
Opening preparation |
Verify dimensions, plumb, level, square, and substrate strength |
Track alignment and panel operation are highly sensitive to frame distortion and uneven support. |
Record the rough-opening survey before delivery. Correct substrate defects before setting the frame; do not force the door to compensate for structural movement. |
| Installation |
Waterproofing and drainage |
Use a continuous sill strategy with end dams, compatible flashing, and open drainage paths |
Many sliding-door failures originate at the sill and perimeter rather than in the moving panel itself. |
Integrate sill flashing with the wall weather-resistive barrier and confirm that weep holes are unobstructed after installation and finishing. |
| Installation |
Fastening and movement allowance |
Anchor according to tested spacing and allow for structural and thermal movement |
Over-constrained frames can bind, leak, or transfer building movement into the glazing and hardware. |
Follow the approved shop drawings and installation instructions. Use compatible packers and avoid placing fasteners where they distort the track or drainage path. |
| Installation |
Glass and panel handling |
Use trained personnel and suitable lifting equipment for large or heavy panels |
Oversized glass can create serious handling hazards and can be damaged by edge impact or incorrect setting blocks. |
Protect glass edges, use the specified setting blocks, keep protective films away from heat sources, and inspect panes for damage before final acceptance. |
| Installation |
Final adjustment and commissioning |
Check smooth travel, lock engagement, seals, drainage, clear opening, and safety markings |
A door that is visually installed but not commissioned may have excessive force, incomplete locking, air leakage, or blocked drainage. |
Complete a documented handover checklist with photographs, measured clear opening, hardware settings, warranty information, and maintenance instructions. |
| Maintenance |
Routine cleaning |
Clean tracks, frames, seals, and glass at least every 6–12 months; clean more often in coastal or dusty locations |
Sand, grit, salts, and construction residue can damage rollers, obstruct drainage, and degrade seals. |
Use clean water and a mild, non-abrasive cleaner. Avoid scraping glass or directing high-pressure water into tracks and drainage openings. |
| Maintenance |
Track and roller inspection |
Inspect at least annually and whenever operation becomes noisy, stiff, or uneven |
Dirty or worn rollers increase operating force and can cause panel misalignment, seal failure, or premature track wear. |
Remove debris with a soft brush or vacuum, check roller adjustment, and replace damaged components instead of forcing the panel. |
| Maintenance |
Lubrication |
Lubricate only components and products approved by the door-system instructions |
Incorrect oils or greases can attract grit, damage polymer components, contaminate weather seals, or interfere with braking hardware. |
Follow the approved maintenance product and application quantity. Do not lubricate drainage holes or surfaces intended to remain dry. |
| Maintenance |
Seals and gaskets |
Inspect annually for compression loss, cracking, shrinkage, gaps, or detachment |
Worn seals reduce air, water, acoustic, and thermal performance even when the panel and frame remain structurally sound. |
Replace seals with compatible profiles and verify corner joints, interlocks, meeting stiles, and perimeter contact after replacement. |
| Maintenance |
Locks and anti-lift devices |
Function-test at least annually and after hardware adjustment |
Security depends on complete engagement of locks, keepers, interlocks, and anti-lift components. |
Confirm that the panel cannot be lifted from the track when closed, that the lock fully engages, and that keys or cylinders operate smoothly. |
| Maintenance |
Drainage and weep paths |
Check before and after severe weather and during scheduled inspections |
Blocked drainage can cause water accumulation, staining, corrosion, and leakage at the sill. |
Keep weep holes and channels clear. Never seal over designed drainage outlets with paint, sealant, debris, or flooring materials. |
| Maintenance |
Replacement planning |
Maintain a component register and inspection record |
Global projects may require replacement parts across different climates, currencies, languages, and supply chains. |
Record panel identification, glass make-up, hardware type, seal profiles, finish, installation date, and approved replacement specifications. |
