A rainscreen system pairs an outer cladding skin that sheds most rainwater with a water- and air-resistive barrier on the structural wall that stops whatever gets through. An air gap between the two drains any water that penetrates the cladding and ventilates the cavity dry.
That's the difference from a barrier wall (one sealed surface, no drainage plane) and a mass wall (thick material that absorbs and buffers moisture instead of shedding it). A rainscreen is designed to let water reach the back of the cladding without letting it reach the structure — that's expected performance, not a defect.
Water crossing a panel joint runs down the back of the cladding to weep openings at the base of the wall.
Venting the gap at top and bottom reduces the pressure difference across the cladding that pulls wind-driven rain inward through joints.
Air moving through the cavity clears residual moisture before it reaches the sheathing or insulation behind it.
For flexible stone, the gap typically runs 1/4" for panels direct-adhered to furring, up to 3/4" for panels mechanically fixed to a grid subframe with more airflow behind them. Exact clearance depends on wind load and local code — no single gap dimension applies to every jurisdiction or substrate.
A rainscreen builds up in five layers, from the structure outward:

Export packing for international freight.
Plate metal substrates need corrosion-resistant fasteners and a rust-preventative primer before installation. Bare steel can rust under moisture exposure.
Concrete and OSB use different fastener spacing and flashing sequences. These details are covered in the rainscreen system guide.
Flexible stone panels use a thin, bendable base with water-based, inorganic, firing-free inkjet printing. Unlike quarried stone veneer, this construction offers different options for rainscreen applications. Full-size exterior stone panels reach 1200×3000 mm across the Travertine, Slate, and Textured series in regular production.
Thickness and weight vary by series and are confirmed in the project quote. The thin base can reduce load compared with slab-based cladding. Compare other options in lightweight cladding materials.
The panel flexes around curves without relief joints, helping keep the drainage plane continuous.
Panels can be adhered to furring or mechanically fixed to a grid subframe, leaving a stand-off gap behind the cladding.
Selected models have manufacturer-reported testing from -40°C to 150°C, along with Grade 4 wear resistance. The surface is rain-washable and easy to clean.
Bracket, clip, rail, and restraint design belongs to the project-specific subframe package. The ventilated facade guide lists the panel information to coordinate. Confirm panel thickness and weight before finalizing load calculations.
No published impact-test rating is available. For high-traffic, ground-level, or vandal-exposed areas, request impact data or plan a separate protective detail.
Every order includes an after-sales warranty, but the duration varies. Confirm the exact term in writing before finalizing the quote.
Flexible panels avoid relief cuts on curves, but planned seams still need consistent spacing and sealing across large spans.
| Type | How it creates the gap | Best suited for |
|---|---|---|
| Furring strips | Vertical wood or composite strips fastened over the wall | Flat walls, simpler labor |
| Drainage mat | Rolled 3D matrix laid over the water barrier | Retrofit or lower-profile gap needs |
| Grid & subframe systems | Engineered metal grid holding cladding off the wall | Panelized claddings, curved or tall facades |
Grid and subframe hardware — brackets, clips, and rail profiles sized for flexible stone spans — is detailed under ventilated facade systems.
| Spec | Typical range/detail |
|---|---|

Panel thickness and weight are confirmed per series with your quote — request them before finalizing bracket or subframe load calculations.
Angtai's manufacturing history traces to 1997. Its 36,000 m² factory now operates four soft porcelain lines, with R&D support from South China University of Technology. The collection has been shown at Marmomac 2025 in Verona and China Homelife Indonesia Expo.
Quotes return within 24 hours, samples ship within 5 days, and production typically takes 25–30 days depending on order size. OEM/ODM support covers custom colors, textures, and sizes.
