Facade systems
An engineered stone facade is a system, not a panel.
The panel carries the face. The brackets, subframe, joints and flashings decide whether the elevation stays flat, drains, and survives movement. Here is how the layers go together.
An engineered stone facade is a drained and back-ventilated cladding system: cast stone panels fixed to a bracketed aluminium or steel subframe, with a movement joint between panels, a ventilated cavity behind, and flashings at openings and tops. The panel is one layer of five, and the specification has to resolve all five.
The five layers
| Layer | What it does | Decided by |
|---|---|---|
| Cast stone panel | Face, weather, colour | Format, finish, thickness |
| Fixing | Undercut anchor or kerf in the cast rebate | Panel weight, wind load |
| Bracket and subframe | Carries load back to structure | Substrate, cavity depth |
| Ventilated cavity | Drains water, equalises pressure | Exposure, detailing |
| Flashing and sealant | Closes openings and tops | Window and parapet detail |
Where cast panels change the system
A 3230 × 1630 mm panel covers 5.27 m². On a 1,000 m² elevation that is roughly 190 panels instead of 700 tiles, which means fewer brackets, fewer anchors and fewer joints to align. The saving shows up on the subframe and on the labour line, not only on the panel line.
Because the fixing rebate and the return are cast into the panel rather than cut afterwards, the edge does not need a separate trim. On a corner, the return can be the same material as the face.
What has to be resolved before production
- Panel layout on the elevation, including the setting-out origin
- Substrate type and the fixing zone available behind it
- Joint width that accommodates movement and tolerance
- Openings, parapets and soffits, where flashings meet the panel
- Any radius, and the maximum piece length the site can handle
Questions buyers ask
- What is an engineered stone facade and who makes it?
- It is a cast or reconstituted stone panel used as exterior cladding on a drained, back-ventilated subframe. NKSTONE manufactures it in Yunfu, Guangdong, in panels of 3230 × 1630 mm.
- Is it a rainscreen or a sealed facade?
- It is normally built as a rainscreen: an open or baffled joint, a drained cavity and flashings. A sealed joint is possible but removes the pressure-equalisation benefit and complicates moisture management.
- Does the facade need a separate vapour barrier?
- That depends on the wall build-up behind the cavity. On a concrete or masonry substrate the panel system is open; on a framed wall the sheathing and membrane are part of the wall design, not the cladding.
