Architectural interiors continue to shift toward cleaner lines, seamless transitions and the quiet sophistication of concealed door systems. Whether it’s minimalist homes, boutique commercial fit-outs, or high-end renovations, when interiors demand doors that visually disappear into the wall while still functioning perfectly, we can offer some ideal solutions.

At Triline, we have three available options designed to achieve this growing design requirement. Together, they allow designers and builders to create flush, streamlined doorways using cavity sliding doors, internal pivot doors, or a hinged door system—without compromising stability, performance or construction efficiency.

Below, we explore the three systems, the problems they solve, and how each one elevates modern interior architecture.

1. The FlushSlide — Coplanar Sliding Door System (Cavity Slider or Track & Fittings)

The FlushSlide is our premium coplanar sliding solution designed to bring sliding door panels perfectly in line with the wall surface when closed. Whether installed as part of a pocket door system or configured with internal sliding door track systems built in with the surrounding joinery, this system delivers a true “hidden door” aesthetic.

Benefits

• Coplanar finish: Door panel sits flush with the joinery or feature wall cladding, creating a clean linear aesthetic.
• Compatible with cavity pocket: Works with concealed cavity sliding doors or as a track-and-fittings option for custom joinery applications.
• Increased Property Value: Spaces featuring sophisticated, flush sliding door systems attract discerning buyers and tenants, adding long-term value.
• Smooth, controlled motion: High-quality rollers and guides ensure quiet and effortless operation.

Applications

• Kitchens and pantries where space-saving design is essential and flush joinery is consistent.
• Ensuites or master suites where designers want the door to visually disappear.
• Architectural homes that favour uninterrupted wall lines.

Problems it solves

• Eliminates bulky architraves or protruding door faces.
• Provides a flush finish.
• Delivers the visual simplicity designers increasingly expect as standard.

2. Pivotica Pro — The Most Invisible Pivot Hinge System for Swing Doors

For hinged openings requiring a truly seamless look, Pivotica Pro is our discrete pivot hinge solution designed for internal pivot doors. Engineered for minimal visibility, it allows a standard or oversized door to appear as though it simply folds out from the wall surface.

Benefits

• Near-invisible pivot hardware hidden within the top and bottom of the door.
• Smooth self-closing or free-swing options depending on the application.
• Suitable for oversized or heavy architectural door panels.
• Clean aesthetic without the visual clutter of traditional pivot hardware.

Applications

• Feature entries into living areas, studies or media rooms.
• Large internal pivot doors used to create dramatic architectural statements.
• Commercial interior fit-outs where durability and design need to coexist.

Problems it solves

• Removes visible pivot hinge mounting plates that interrupt floor or ceiling continuity.
• Enables wider, taller, heavier doors without specialised framing.
• Provides a premium “monolithic door” aesthetic ideal for minimalist interiors.

3. EzyConcept Inswing Door Jamb — Flush Solution for Hinged Doors

For projects requiring a more conventional hinged door but still wanting a flush, architrave-free finish, the EzyConcept Inswing Door Jamb provides an elegant alternative to traditional jambs.

Benefits

• Flush finish between the door jamb and wall surface.
• Easy to paint, finish and integrate into existing wall construction.
• Delivers a streamlined architectural look without the complexity of custom joinery.

Applications

• Bedrooms, bathrooms or utility rooms where a simple flush  or hidden door is preferred.
• Renovations aiming to modernise older homes.
• Commercial interiors requiring crisp, uniform lines.

Problems it solves

• Removes bulky architraves that date or visually clutter an interior.
• Allows hinged doors to align seamlessly with plasterboard walls.

Creating a Seamless Interior, One Door at a Time

As architectural trends continue to favour seamless detailing, builders, architects and designers are looking for systems that integrate effortlessly into their workflow while elevating the final result. Whether it’s the coplanar innovation of the FlushSlide, the near-invisible engineering of Pivotica Pro, or the simplicity of the EzyConcept Inswing Door Jamb, Triline offers flush-finish solutions for every type of opening.

Clean lines, functional performance and uncompromised design—exactly what today’s interiors demand.
