Granite Curtain Wall Systems

A granite curtain wall is a non-structural façade system that fixes natural-stone panels to a building's structural frame through mechanical anchoring rather than mortar or wet-set adhesive.

APEX EcoBuilt engineers, fabricates, and OEM-supplies these systems around our granite facade cladding panels, covering the granite facade cladding itself plus the anchoring hardware that carries it.

Granite Curtain Wall Anchoring & Mounting

  • Slotted (Kerf)

  • Project Review
  • Stage One

    Set the Anchoring Method

    Granite panel anchoring is decided before any panel is cut. Panel size, wall height, wind and seismic criteria, and the required facade appearance all influence the fixing method.

    • Match the anchor type to panel size and weight
    • Coordinate fixing lines with the wall structure
    • Confirm joint and replacement requirements
    Request an Anchoring Review
  • Method One

    Back-Bolted Anchoring

    Undercut anchors are drilled into the rear face of the granite panel, keeping the exterior surface clean with no visible fasteners. This method suits taller or heavier panels where a monolithic facade appearance matters.

    • Undercut anchors drilled into the panel rear
    • No visible fasteners on the exterior face
    • Suitable for taller or heavier premium facades
    Discuss Back-Bolted Fixing
  • Method Two

    Slotted (Kerf) Anchoring

    Clips engage a groove machined into the panel edge, concealing the fixing at the joint line rather than on the granite face. It is a cost-effective method for flush commercial facades with moderate panel sizes.

    • Clips engage a groove in the panel edge
    • Fixings remain concealed at the joint line
    • Suitable for standard commercial facades
    Discuss Kerf Anchoring
  • Method Three

    Dry-Hang Systems

    Panels hang on mechanical hangers without wet-set adhesive or a mortar bed. This rainscreen-style approach speeds installation and makes future panel replacement easier without disturbing adjacent units.

    • Mechanical hangers replace wet-set adhesive
    • Supports a rainscreen-style installation
    • Simplifies future panel replacement access

  • Project Review

    Confirm Project-Specific Loads

    Panel thickness, weight, and anchor load requirements are set per project rather than taken from a generic catalogue specification. Elevation drawings and local wind or seismic criteria should be reviewed before fabrication.

    • Check anchor loads against panel weight
    • Coordinate brackets, joints, and load paths
    • Approve the layout before panels are cut

Capability

Material & Fabrication Capability

  • Material range

    Granite is part of APEX's stone curtain wall systems line, alongside limestone, terracotta panel curtain wall systems, and artificial stone brick.

  • Finishes

    Polished, honed, flamed, and brushed finishes are matched to the project during design review.

  • Manufacturing

    Fabrication takes place in APEX's 150,000 m² factory, backed by 20 years of curtain wall manufacturing experience.

  • Lead time

    Because granite is quarried, cut, and finished per order, timing depends on stone sourcing, panel size, anchoring method, and quantity. A project timeline is confirmed after design review.

Why APEX

Why APEX EcoBuilt

APEX holds 179+ patents and certifications across its curtain wall and aluminum systems, and runs an 80+ country global business supplying both catalog and custom OEM orders — including OEM programs for international residential brands.

Every granite façade order goes through the same BIM/FEA structural validation used across our curtain wall lines, not a stripped-down process reserved for glass or metal panels. Developers we've worked with on façade programs include Poly, Country Garden, and Kaisa, among other regional and international groups.

Materials

Granite vs. Other Curtain Wall Materials

  • Granite vs. stainless steel

    Granite is heavier per panel, so anchoring and support spacing must be addressed earlier in design. Stainless steel curtain wall systems provide a lighter, more uniform metal finish.

  • Granite vs. terracotta

    Granite creates a denser, more monolithic stone appearance. Terracotta panel curtain wall systems offer lower unit weight and a more textured, matte surface.

  • Selection criteria

    Neither material is universally better. The choice depends on the structural load path and the finish specified by the architect.

FAQS

Frequently Asked Questions

What's the minimum granite panel thickness you supply?
Thickness is set per project based on the anchoring method and panel size — back-bolted systems typically need thicker stock to carry the undercut anchor safely, while slotted or dry-hang panels can run thinner. We confirm exact thickness once we review your structural loads and elevation drawings.
What's the typical lead time for a granite curtain wall order?
Lead time depends on stone sourcing, fabrication complexity, and order volume, since granite blocks are cut and finished specifically for each project rather than pulled from generic stock. We provide a project-specific timeline once panel sizes, anchoring method, and quantities are confirmed.
Is there a weight limit for granite curtain wall panels?
Panel weight is managed through the anchoring method and support spacing rather than a fixed cap — back-bolted anchors are engineered by BIM/FEA to carry heavier panel loads, while lighter dry-hang installs suit smaller panel formats. We size the anchoring during structural review based on your specific panel dimensions.
Can individual granite panels be replaced after installation?
Yes — dry-hang and slotted systems use mechanical, reversible fixing, so a single damaged panel can be removed and replaced without disturbing surrounding units. Back-bolted panels can also be replaced, though access typically comes from the panel face given the rear-anchor design.
