Holographic Glass: Where Light Becomes Design (and Useful, too)
If you’ve ever watched rainbow light skate across a hotel lobby and wondered how they pulled that off, there’s a good chance it was holographic glass. I’ve seen it in retail pop-ups in Shanghai and in a quiet museum stairwell in Milan—two wildly different vibes, same technology.
What it is (and why designers keep asking for it)
holographic glass—sometimes called polyhologlass—is essentially laminated glass with a transparent diffraction (holographic) film sandwiched between layers. It was first introduced in Taiwan and, to be honest, it’s moved fast from “niche art glass” to mainstream architectural feature. Many customers say it’s the sweet spot between statement piece and practical safety glass.
Quick Spec Snapshot
| Substrates | Clear/low-iron tempered glass laminated with EVA or PVB + PET holographic film |
| Thickness (overall) | ≈ 6–12 mm common; custom up to 21 mm |
| Max sheet size | ≈ 2400 × 3600 mm (real-world use may vary by kiln/autoclave) |
| Visible transmittance | ≈ 70–88% (depends on film density and color) |
| UV blocking | ≈ 95–99% with PVB/EVA interlayers |
| Impact safety | Meets laminated glass norms (e.g., EN 12600 2B2/3B3, ANSI Z97.1 Cat A) when specified |
| Service life | Indoor ≈ 10–20 years; protected exterior edges ≈ 8–15 years |
How it’s made (the short, honest version)
- Materials: low-iron tempered panes, PET holographic diffraction film, EVA/PVB interlayer.
- Prep: deionized wash, dust-free handling; edge arris or polish.
- Lamination: film centered between glass + interlayer → vacuum bag or nip roll → autoclave (≈ 120–140°C, pressure controlled).
- Quality tests: haze/transmittance (spectrophotometer), adhesion (pummel), impact (EN 12600), fragmentation (ANSI Z97.1).
- Finishing: CNC cutting pre-temper, waterjet logos, edge sealants for exterior use.
Origin matters, too: production I toured in Yushui Economic Development Zone, Shahe City, Hebei, China, has dialed in consistency—surprisingly clean color across batches.
Where it works best
- Retail fronts and pop-up partitions (brand “wow” without heavy signage)
- Hospitality: lobby balustrades, feature walls, elevator cabins
- Museums and culture: wayfinding panels, light wells, cases
- Workplaces: meeting room dividers with privacy + sparkle
- Transit and events: stage sets, rail station art glazing
Advantages? holographic glass diffuses natural light, blocks UV, and keeps fragments bound if broken—form and function in one layer cake. Maintenance is basically standard glass care (no abrasives on coatings, obviously).

Real-world notes, tests, and standards
Our recent panels (1.52 mm PVB + PET film) achieved EN 12600 2B2 on 8.76 mm builds; spectro reads came back with 82% VLT on low-iron. Customers say glare is lower than expected, and, actually, privacy improves at off-angles. For compliance, specify laminated safety per ISO 12543/EN 14449 and ensure local code alignment with ANSI Z97.1 or EN 12600.
Customization
- Film patterns: fine rainbow, coarse diffraction, gradient, logo-embedded.
- Edges: polished, mitred; hardware-ready holes/slots (pre-temper).
- Color tuning: pair holographic glass with tinted substrates for moodier looks.
Mini case studies
- Flagship Retail, Seoul: 150 m² of holographic glass partitions lifted dwell time by ~12% (retailer POS data) while keeping UGR within spec.
- Boutique Hotel, Barcelona: balcony balustrades in 10.76 mm holographic glass passed onsite pendulum impact; guest photos skyrocketed on socials—free marketing.
Bottom line
Use holographic glass when you want light to do the storytelling—without sacrificing safety. And, I guess, to make your photographer very happy.
