Four-Leaf Bifold Patio Doors with a Traffic Door
The configuration places four 900 mm-wide nominal modules inside one perimeter frame. The inner grid is 3600 × 2400 mm, while the outer frame is 3680 × 2480 mm. Module dimensions organize the design; the shop drawing sets the joints, pivots and fabrication clearances within that grid.
Three glazed modules form the linked folding bank. Their hinges and carriers are coordinated as one operating assembly, with the fold side shown on the room plan. The fourth module has its own independent traffic-door operation.
The traffic leaf is an independently hinged everyday door within the same frame, with its own handle and latch. Traffic access at the right jamb pairs with a left-side folding bank, and the alternative mirrors that arrangement.
The specified frame uses thermally broken aluminum profiles with a charcoal powder-coated finish. The 40 mm perimeter-frame face and 60 mm leaf-profile face requirements are carried into the drawing with the rebates and hardware interfaces.
The glass schedule uses 6 mm glass, a 16 mm cavity and 6 mm glass, giving 28 mm nominal insulating-glass-unit thickness. The project glass specification identifies the required safety-glazing selection, coatings and load basis together with the frame support detail.
Threshold sections, perimeter seals, traffic-door latch parts and folding hardware are listed as one package. Finished-floor levels and drainage details establish the threshold interface, while handle position follows the selected traffic-door handing.

Select left- or right-jamb access from the actual approach route and furniture plan. The order drawing shows the traffic leaf swing, folding-bank position and hardware side together so the daily opening and wider opening work within one room arrangement.
The site schedule identifies the structural opening, support framing and finished-floor datum. The 3680 × 2480 mm outer frame is the product configuration basis; installation joints and anchor positions are detailed against the actual opening construction.
The section records the interior and exterior floor levels, drainage route and threshold seating. The operating plan also reserves the traffic swing and folded-leaf envelope, tying the frame to the terrace and interior finishes.
The quotation lists one perimeter frame and four glazed leaf modules, split into the three-leaf folding bank and independent traffic leaf. The chosen traffic-jamb configuration appears on the same line as the frame size.
Pricing follows the 6/16/6 glazing schedule and the selected thermally broken aluminum profile system. Glass coatings, safety-glazing requirements and finish references are listed as specific package items.
The hardware schedule separates folding hinges and carriers from the traffic-door latch and handle. Threshold parts, seals and closing components are coordinated with the selected handing and opening layout.
The project drawing identifies the structural opening and floor interface. Packing labels distinguish frame members, glass and hardware groups, with opening numbers connecting each package to its installation position.
Three leaves form a linked folding bank and the fourth operates as an independent traffic door. The right-jamb traffic option folds the linked bank to the left; the alternative mirrors the arrangement.
The outer frame is 3680 × 2480 mm. Its inner grid is 3600 × 2400 mm, organized into four 900 mm nominal module widths. The shop drawing resolves joints and fabrication clearances within that grid.
It specifies 6 mm glass on each side of a 16 mm cavity, giving 28 mm nominal insulating-unit thickness. The project glass schedule adds the safety-glazing, coating and load requirements.
Use the normal access route and room layout to select the left or right jamb. The drawing shows the traffic swing and folding-bank position together.
The section records interior and exterior finished-floor levels, drainage, threshold seating and frame support. Those interfaces are coordinated with the operating hardware and surrounding finishes.
Opening numbers identify the frame, glazing and hardware groups. The supply schedule lists folding components, traffic-door parts, seals and threshold pieces against the selected handing.
