Manufacturing Process of Rain Glass

The creation of rain glass involves advanced glass forming, texturing, and tempering to ensure both artistic and functional performance. Below we detail the standard process flow for 4mm 5mm 6mm Rain Pattern Glass:

Rain Glass Manufacturing Flowchart

Float Glass Selection: Start with high-clarity float glass (SiO₂ > 72%), rigorous checks for inclusions or bubbles.
Patterned Rolling: Molten glass rolled between precision-engraved rollers (rain pattern glass textures depth up to 0.6mm), ensuring consistency.
CNC Cutting & Edgework: Precise sizing, edges ground/polished according to project specs (EN 12150/ASTM C1036).
Tempering or Heat Strengthening: Glass heated to ~650°C and rapidly cooled for mechanical strength (up to 3–5× normal).
Inspection & Testing: Final product checked to ISO 9001, ANSI Z97.1 standards (flatness, haze, strength, texture accuracy).

Application Scenarios & Performance Advantages

Rain glass delivers unique benefits in various industries thanks to its characteristic vertical ripple texture, light diffusion, and resistance to environmental stress. Its design-oriented surface also acts as a privacy barrier while allowing natural daylight into interiors.

Primary Application Fields:

Commercial Building: office partitions, upscale facades, bathroom enclosures
Modern Residences: shower rooms, entry doors, window panels
Industrial Sectors: control rooms (oil, petrochemical, power plants)
Public Space: hospital lobbies, transportation terminals
Water Treatment: corrosion-resistant screen partitions

Technical Advantages:

Privacy without darkness (up to 85% daylight transmission)
Decorative surface resists fingerprint, stains
Excellent thermal shock, wind, and impact resistance
Non-porous; does not harbor bacteria or mold (ideal for cleanroom & food facilities)
Customizable size, pattern depth, and tempering grade to fit project needs

Typical Use Case: Rain Glass in High-End Shower Enclosures

A leading hotel in Singapore chose 6mm rain pattern tempered glass for its premium suites' shower rooms. The advantages cited included:

Privacy for guests without sacrificing light or luxury
Superior resistance against cleaning agents and water hardness stains
Longer service life than frosted or acid-etch alternatives
ANSI Z97.1 impact test proven: zero breakage in 100+ doors over 7 years
Minimal fingerprint retention; easy maintenance for cleaning staff

Feedback from the facility manager: “Switching to rain glass cut our replacement frequency in half while elevating the guest experience—a win-win.”

FAQs on Rain Glass Technology and Application

1. What is the main difference between rain glass and frosted glass?

Rain glass's patterned surface is achieved by rolling molten glass between textured rollers, creating visual vertical ‘rain’ lines. Frosted glass is formed via sandblasting or acid-etching, producing a uniform, matte look but less light diffusion. Rain glass preserves more natural daylight and provides a dynamic privacy effect.

2. Are rain pattern glass and rainfall glass the same?

Yes, both refer to glass featuring a similar vertical, water-droplet-like texture, but "rainfall glass" sometimes implies larger droplet impressions. Check with your supplier for pattern samples.

3. What is the recommended installation standard for rain tempered glass?

Install per ANSI Z97.1/EN 12150-1 (for safety glazing): secure into frames with appropriate clearances (typically 3mm min) and use compatible silicone or EPDM gaskets to allow thermal expansion and absorb stress.

4. What is the minimum order size for custom rain pattern glass?

MOQ is usually 50m² for custom thickness/pattern design, but standard rain glass is available from 5 pieces up.

5. What safety tests are performed on rain tempered glass?

Tests per ISO/ANSI: impact resistance (steel ball drop), fragmentation, light transmittance (ASTM E903), and thermal shock performance (EN 12150-1 Appendix A), all with full traceable records provided to clients.

6. Can rain glass be double glazed for better insulation?

Yes, rain glass can be combined in IGU (insulated glass units) for improved U-value and noise reduction, ideal for energy-efficient windows and doors.

7. What is the expected service life of rain glass in industrial environments?

Properly installed and maintained, 4mm–6mm rain glass routinely lasts 20–35 years, retaining at least 85% of initial clarity and pattern definition (laboratory test: EN 1096 accelerated weathering).
