Opening Type and Layout
Choose the Movement Before Refining the Frame and Glass
Opening width, usable clear opening, panel storage, traffic, interior space and exterior exposure determine whether a sliding, lift-and-slide, bifold, barn or pocket arrangement is appropriate.

Sliding and Multi-Track Doors
One or more moving panels slide beside fixed or moving panels. Review the required clear opening, panel sequence, track count and available frame depth.
- Two-panel and multi-panel layouts
- Fixed-plus-sliding or all-sliding options
- Interior or exterior applications

Bifold Door Systems
Hinged panels fold and stack to one or both sides. Coordinate panel count, traffic leaf, stacking direction, swing zones, carrier hardware and structural support.
- Left, right or split stacking
- Optional daily-use access leaf
- Top-hung or system-specific support

Barn and Interior Sliding Doors
A wall-mounted track can avoid a swing zone, but the adjacent wall must remain clear for the open leaf. Privacy, floor guides and closing interfaces need separate review.
- Wood, glass or framed panels
- Single or paired leaves
- Exposed or covered track hardware

Pocket Door Systems
The open leaf retracts into a wall pocket. Frame depth, internal services, access to rollers and guides, finished opening and wall construction must be coordinated early.
- Single- or double-pocket layouts
- Solid, glazed or framed leaves
- Service-access planning before closing the wall

Complete System Construction
Specify the Frame, Moving Panels and Interfaces as One Assembly
A coordinated sliding opening includes the head, jambs, sill, moving and fixed panels, glass or infill, carriers, rollers, guides, interlocks, seals, drainage, locks and connections to the surrounding construction.
- Confirm panel dimensions and weights against the proposed profiles, rollers and track system.
- Coordinate structural support, frame fixing zones, tolerances and deflection allowances.
- Record sill or threshold height, finished floor level, drainage path and waterproofing interface.
- Identify replaceable hardware, adjustment points and future maintenance access.
Do not treat a generic profile image as the final specification. The approved shop drawing and product schedule should describe the system proposed for the actual opening size, configuration and exposure.
Frame and Panels
Review profile depth, panel joints, reinforcements, interlocks, meeting stiles, fixed-panel retention and connection details.
Track, Rollers and Guides
Match carriers, roller capacity, track material, adjustment range and floor guides to panel size, weight and intended use.
Sill, Seals and Drainage
Coordinate threshold height, weather seals, brush seals, drainage routes, end caps, finished levels and adjacent waterproofing.
Locks and Accessories
Define handles, pulls, locks, cylinders, flush bolts, restrictors, soft-close parts, insect screens and access-control interfaces.
Glass, Finish and Hardware
Coordinate the Visible Design With the Operating Requirements
Reference images help define appearance, but final selections must also suit panel size, weight, exposure, safety locations, access, maintenance and the required project documentation.
Daylight, Privacy and Safety
Coordinate clear, tinted, low-e, laminated, toughened, patterned or privacy glass where available. Confirm make-up, thickness, edge treatment, safety location and evidence for the proposed panel size.
Profile, Colour and Finish
Review sightlines, mullion divisions, internal and external colour, powder-coated or anodized finish, wood-effect options, gloss level and controlled sample references.
Handles, Locks and Screens
Match pulls, recessed handles, locks, cylinders, interlocks, child-safety provisions, screens and optional automation to the system, traffic pattern and local requirements.
Thermal, acoustic, water, air, wind, impact or security performance belongs to a tested or documented complete assembly—not to the glass, frame or hardware in isolation.
Selection Checklist
Resolve the Opening Conditions Before Selecting a System
A similar-looking opening may require a different panel layout, track, sill, glass and hardware when its dimensions, exposure, access or performance requirements change.
Opening and Panel Layout
Record structural and finished opening sizes, desired clear opening, panel count, fixed panels, stacking side and operating sequence.
Interior or Exterior Use
Identify the room or façade location, traffic, rain, sun, humidity, salt air, overhangs and maintenance access before comparing systems.
Floor and Drainage
Coordinate finished floor levels, recessed or raised tracks, drainage, waterproofing, cleaning access and trip or accessibility considerations.
Panel Size and Support
Review glass weight, panel height and width, roller capacity, head support, fixing zones, structural movement and transport limitations.
Operation and Access
Define handle positions, locking, daily-use panel, opening force, screens, child-safety needs, automation and emergency-access requirements.
Codes and Evidence
List required local standards, test reports, ratings, submittals and approval authority. Do not assume one generic system suits every jurisdiction.
Quotation Preparation
Information Needed for a Comparable Sliding Door Quotation
A reference photo is useful, but a comparable quotation also needs opening, layout, material, glass, hardware, performance and delivery information.
| Input | What to Provide | Why It Matters |
|---|---|---|
| Opening Schedule | Door marks, quantities, locations, structural and finished opening dimensions. | Controls scope, coordination and item-by-item comparison. |
| Layout and Movement | Sliding, lift-and-slide, bifold, barn or pocket; panel count; fixed panels; opening and stacking direction. | Defines tracks, carriers, clear opening and required storage space. |
| Frame and Finish | Preferred material, profile appearance, colour, finish reference and internal/external colour requirements. | Affects system choice, appearance, exposure review and sample approval. |
| Glass or Panel | Glass make-up, privacy, safety, low-e or other requirements; or solid-panel construction and finish. | Affects panel weight, profiles, rollers, safety and documented performance. |
| Track and Threshold | Recessed or raised track, floor levels, drainage, waterproofing, accessibility and cleaning access. | Prevents conflicts at the most installation-sensitive interface. |
| Hardware and Access | Handles, locks, cylinders, screens, soft-close, restrictors, automation or access-control requirements. | Allows compatible preparation and complete scope comparison. |
| Performance and Documents | Required air, water, wind, thermal, acoustic, impact, security or other criteria and evidence. | Links claims to the proposed complete system and approval needs. |
| Project and Delivery | Project location, site constraints, required delivery point, packaging preferences and programme milestones. | Supports exposure review, logistics planning and a realistic quotation basis. |
Ask each quotation to identify inclusions, exclusions, loose accessories, proposed glass, hardware, finish, documentation and packaging. This makes alternatives easier to compare.
Project Coordination
From Opening Schedule to Approved Production Information
Release should follow coordinated dimensions, panel movement, frame, glass, track, sill, drainage, hardware, finish and required documentation—not a reference image alone.
Schedule Review
Review door marks, quantities, opening sizes, desired clear opening, floor levels, exposure, project location and missing inputs.
System and Layout Proposal
Coordinate opening type, panel count, fixed panels, stacking or sliding direction, frame, glass, sill, hardware and documented criteria.
Drawing and Sample Approval
Confirm elevations, sections, dimensions, movement, drainage, fixing, hardware preparation and controlled finish or glass references.
Production, Checks and Packing
Follow approved information, record agreed visual and functional checks, protect profiles and glass, and label packages by opening reference.
Approval and Delivery Records
Keep the Approved System Traceable Through Production and Packing
The agreed scope should remain linked to each opening reference so drawings, finishes, glass, hardware, recorded checks, loose items and packages can be compared.

Drawings and Controlled References
Approve door marks, elevations, sections, panel movement, dimensions, sill details, drainage, fixing, glass, hardware and finish samples before production.

Visual and Functional Checks
Record agreed checks for overall dimensions, panel sequence, roller movement, alignment, locking, finish, glass identification, drainage details and scheduled accessories.

Protected and Referenced Packing
Protect profiles, corners, glass, tracks and finishes; separate loose hardware; and mark packages, crates and accessory boxes by opening or package reference.
The exact inspection scope, records and packing method should be agreed in the quotation or order documents. Photos and videos do not replace required product-specific reports or site inspection.

Sliding and Bifold Door Project Questions
Final answers depend on the proposed system, opening size, panel layout, glass, hardware, exposure, installation and required project documentation.
What is the difference between sliding and bifold doors?
Sliding panels move parallel to each other and normally remain within the frame area. Bifold panels are hinged together and stack to one or both sides. Compare usable clear opening, stacking space, swing zones, sill conditions, traffic and maintenance before selecting either arrangement.
Can sliding doors be made to custom sizes?
Project-specific openings and panel layouts can be reviewed against available system limits, profile strength, glass or panel weight, roller capacity, structural support, exposure and transport constraints.
Can a sliding door use a recessed or low threshold?
Threshold options depend on the system and application. Coordinate finished floor levels, drainage, waterproofing, air and water requirements, accessibility, cleaning and site installation before approving a recessed or reduced sill.
What glass options can be used?
Clear, tinted, low-e, laminated, toughened, patterned or privacy glass may be considered where available. Confirm safety location, make-up, thickness, panel size and any required thermal, acoustic, impact or security evidence.
Are sliding doors suitable for exterior or coastal projects?
Suitability depends on the complete frame, finish, fasteners, glass, seals, drainage, hardware, installation and maintenance. State rain, wind and salt-air exposure before quotation so the proposed system and supporting evidence can be reviewed.
Can automatic sliding doors be included?
Automation can be considered as a separate system requirement. Confirm door type, operator, sensors, controls, power, access, safety functions, emergency operation, maintenance and applicable local requirements before production.
How should sliding door tracks and rollers be maintained?
Cleaning, adjustment and replacement requirements vary by system and exposure. Keep tracks free of debris, protect drainage paths and follow the approved supplier instructions for rollers, locks, seals, screens and finishes.
What should I send for a quotation?
Send the opening schedule, drawings, quantities, structural and finished sizes, opening type, panel layout and movement, frame and finish, glass, sill, drainage, hardware, project location, required documentation and delivery information.
