Opening Type · Bi-Fold
Open Up
the Entire Wall.
Not just another patio door.
When closed, a bi-fold door frames the view. When open, it folds neatly to the side — dissolving the boundary between indoors and out. Designed for expansive openings, it creates one uninterrupted connection between architecture, landscape, and the people inside.
Why Bi-Fold
Everything. Out of the way.
Unlike sliding doors that always leave one panel fixed, bi-fold doors stack almost completely clear of the opening. The result is a true wall opening that transforms patios, entertaining spaces, and interior rooms into one continuous environment.
Whether opening onto a terrace or dividing interior living spaces, the architecture becomes more flexible with every panel folded away.
Maximum opening
Panels fold neatly to one or both sides, creating a wide, unobstructed passage where a wall once stood.
Indoor–outdoor living
Blur the transition between the home and the landscape — the room and the terrace become a single space.
Natural light
Floor-to-ceiling glazing keeps interiors bright and open even when the doors are closed.
Custom configurations
Built around your exact opening, with multiple panel layouts and stacking options engineered to fit.
Applications
Where they belong.
A bi-fold door earns its place wherever a wall should be able to disappear — opening the home to the landscape, and dividing interior rooms into spaces that flex with the moment.
Patio living
Create a seamless connection between indoor living spaces and terraces, courtyards, pools, and outdoor entertaining areas — the whole wall folded clear to the side.
Interior spaces
Replace solid walls between living rooms, dining rooms, kitchens, or event spaces with flexible glass partitions that open completely when desired.

Open. Fold. Disappear.
Configuration Guide
Built around your opening.
Every project is fabricated specifically for its opening. Panel count, stacking direction, and swing are all set to the wall. Gold marks the primary access leaf and the direction panels stack. Representative only.
The final configuration depends on opening width, panel weight, hardware, and project requirements.
Materials & Performance
Beauty that still performs.
Every BlackFramed bi-fold door is fabricated using original European steel profile systems, selected for exceptional rigidity, slim sightlines, and long-term durability — because a folding wall carries its weight on moving hinges, the steel behind it matters most.

Compatible Profile Systems
Which steel a fold runs on.
A folding door lives or dies by its rigidity, so exterior bi-folds move to our thermally broken systems for weather and long-term geometry. Interior partitions can run on our slimmer steel.
W40 Slimline
A precision hot-rolled 40mm profile — clean sightlines for folding walls where slenderness matters and the climate is moderate.
W50-TB Ottostumm
A deeper thermal-break profile for tall or wide folding runs where the frame is meant to be seen — heritage proportions with real performance.
Secco OS2-75 Contemporary
The most thermally capable system — for the largest, heaviest folding walls where energy performance and slim sightlines both matter most.
BF S20 Cold-formed
Our slimmest interior system — a cold-formed profile for folding partition walls and internal glazed screens on the thinnest possible sightline.
