Curtain Wall Manufacturer China Factory Price Aluminum Unitized Glass Facade Thermal Break

1. System Overview — A Facade That Must Be Weatherproof, Structural and Replaceable

A curtain wall does not carry the building’s floors, but it carries everything the weather and the wind can do to them, and it does so as a repeating system rather than as individual windows. Richocean fabricates unitised and stick curtain wall systems in Foshan from 6063-T6 extrusions with thermally broken mullions, drained and pressure-equalised glazing rebates, and factory-assembled units that are hoisted into place rather than assembled in mid-air.

Three duties define the design. It must keep water out at design pressure, transfer wind load into the structure without over-stressing the glass, and allow a broken pane to be replaced from inside or by a small crane without dismantling the facade. Systems that satisfy the first two and forget the third become expensive buildings to maintain.

2. Core Material Science — 6063-T6 Mullions and Transoms

In a facade, mullions are beams and transoms are rails, and their sections are sized by span and tributary area rather than by appearance. Richocean specifies 6063-T6 aluminum aged to 170 MPa yield, with mullion wall thickness of 2.5–3.5 mm on typical grids and heavier sections where floor-to-floor height or wind pressure demands it, plus steel inserts or reinforced sections at the worst spans.

Thermal breaking on a facade is a system property: every mullion, transom and anchor bracket that crosses the envelope’s insulation line is broken, because one unbroken bracket reinstates the heat path the rest of the facade removed.

3. Glazing, Silicone and Visual Systems

The visual language of a facade is chosen from a small set of glazing systems, each with a different engineering consequence:

• Captured glazing: pressure plates and covers hold the glass, giving strong weather performance and serviceable joints
• Structural silicone glazing: silicone bonds the glass to the frame, producing flush external surfaces with no visible pressure plate
• Two-sided versus four-sided silicone: how many edges are bonded determines load path and how panels are replaced
• Glazing build: double or triple glazed Low-E units, laminated where required, sized by wind pressure and span
• Solar control: coatings, fritting and body-tinted glass selected for the facade’s orientation and heat load
• Spandrel and opaque panels: insulated metal or glass spandrels with back pans so floor slabs are screened
• Fins and feature elements: external blades for shading or architectural rhythm, fixed to the mullion grid

Structural silicone is not a weather seal; it is a structural connection whose bite and thickness are engineered and whose adhesion is verified by test, so it is specified as a system rather than applied as a sealant.

4. Weatherproofing — Drainage, Pressure Equalisation and Movement

Facade water control is a pressure problem before it is a sealing problem:

• Drained rebates: glazing pockets drained to the mullion and out at designed weeps
• Pressure equalisation: compartmentalised rebate volumes with controlled venting reduce the pressure that drives water inward
• Gaskets and seals: continuous EPDM gaskets as the primary line, with wet seals used strategically rather than everywhere
• Interlock seals: unit-to-unit gaskets and splice sleeves keeping the line continuous between stacked units
• Movement: vertical and horizontal movement joints and slotted connections accommodating slab deflection, drift and thermal movement
• Air and water: laboratory tested to ASTM E283 and ASTM E547, with field water testing per AAMA 501.2 where the specification calls for it
• Condensation: thermal break at every crossing member and warm-edge spacers in the glazing units

Where a facade moves, the seal that does not move with it fails; that is why movement allowance is designed into the splice rather than absorbed by gasket compression.

5. Structural Performance, Anchorage and Fire Interface

The facade hangs off the structure at designed points, and the whole system’s behaviour depends on how those points are detailed:

• Design pressure: derived from the project’s wind loading, including height, terrain and local coefficients
• Mullion deflection: limited so glass stress, gasket compression and visual bowing stay within stated criteria
• Anchor brackets: designed for wind load plus the facade’s dead load, with tolerances for site adjustment in three axes
• Slab edge conditions: embedment, cast-in channels or post-fixed anchors chosen against the structural detail
• Movement capability: brackets allowing seismic drift and slab deflection without loading the mullions
• Testing: structural performance to ASTM E330 and, for large projects, mock-up testing to AAMA 501 protocols
• Fire and smoke: perimeter fire containment and spandrel detailing coordinated with the building’s fire strategy

A facade mock-up is where the drainage, thermal and structural assumptions of the whole system are verified at once, so for major projects it is treated as a design step rather than a formality.

11. Price Factors — What Drives Cost

Curtain wall is priced per square metre, but the rate depends heavily on system, performance target and geometry. Cost drivers include:

• System type: unitised versus stick, and captured versus structural silicone glazing
• Design pressure and height: higher wind loads increase mullion sections, glass thickness and anchors
• Glazing build: double versus triple glazed units, laminated panes and solar control coatings
• Grid complexity: openable windows, fins, feature elements and non-repeating geometry
• Spandrel treatment: insulated panels, back pans and fire containment detailing
• Testing scope: laboratory performance testing and mock-up testing requirements
• Finish and exposure: anodized, powder coat or PVDF, and C5-M grade for coastal sites
• Logistics and access: unit size, transport constraints, cranage and site access

12. Installation, Commissioning & Maintenance

Facade installation is a sequence discipline, and the settings made on site determine whether the tested performance is achieved:

• Setting out: grid established from the building’s control lines, with tolerances agreed against slab construction tolerance
• Bracket installation: surveyed in three axes so units can be adjusted and aligned without forcing
• Unit hoisting: units lifted on designated points, interlocked and sealed as the erection progresses to keep the line continuous
• Sealing: splices and gaskets completed as specified, with wet seals applied under the defined conditions
• Testing: field water testing and, where required, field air testing on completed areas before handover
• Cleaning and protection: installed areas protected until handover, with any damaged gasket or seal replaced rather than patched
• Maintenance: scheduled inspection of gaskets, seals, drainage weeps and anchor brackets, with glass replacement per the agreed strategy

Handover should record the as-built grid, the design pressure the system was tested to, the glazing build by orientation and the maintenance and replacement strategy.
