Mirror Glass – The Iconic Choice for Striking Facades, Privacy & Solar Control
Reflective window glass – commonly known as mirror glass – is float glass with a thin metallic or metal‑oxide coating applied to one surface, creating a mirror‑like appearance from the exterior while maintaining visibility from the interior. The coating reflects a significant portion of solar radiation, providing excellent heat rejection and daytime privacy.
For procurement managers and architects designing landmark commercial towers, luxury hotels, corporate headquarters, and high‑end retail destinations, reflective window glass delivers the unmistakable visual impact of a mirror facade while contributing to energy performance. From the cool blue of a tech campus to the warm gold of a casino resort, reflective glass defines the skyline of modern cities.
💡 Why reflective glass is specified: Reflective glass accounts for approximately 10–15% of the architectural glass market but dominates the premium facade segment. Its distinctive appearance is often required by masterplan design guidelines for business districts. Reflective glass commands a 40–80% premium over clear float, driven by the coating process and specialised handling. For glass exporters, reflective glass is a high‑visibility product that signals technical sophistication.

Reflective glass creates a uniform mirror surface that changes appearance with lighting conditions – from bright silver during the day to deep tones at dusk. This dynamic quality makes it the preferred choice for iconic buildings.
With SHGC as low as 0.18–0.45 (in IGU), reflective glass outperforms most body‑tinted glasses. The coating reflects solar infrared radiation before it enters the building, reducing cooling loads by 40–60% compared to clear glass.
The mirror effect makes it nearly impossible to see into the building from outside during daylight hours, while occupants enjoy clear outward views. This is ideal for offices, hotels, and ground‑floor retail.
Low VLT (8–35%) dramatically reduces interior glare, improving visual comfort for occupants working near windows.
Reflective coatings block 80–90% of UV radiation, protecting interiors from fading.
The distinctive appearance of reflective glass – especially in signature colours like gold or blue – becomes part of a building’s brand identity, instantly recognisable in the cityscape.
Some reflective coatings incorporate a Low‑E function, providing both mirror appearance and thermal insulation. These are available in select colours.
| Thickness | Silver VLT | Bronze VLT | Application |

| 4mm | 18% | 26% | Interior partitions |
| 6mm | 16% | 24% | Standard windows (hard coat only) |
| 8mm | 14% | 22% | Large windows |
⚠️ Important: MSVD (soft‑coat) reflective glass must be used in an IGU with the coating facing the cavity. It cannot be used as monolithic exposed glass.

Required Information:
Q1: What is reflective window glass?
Float glass with a metallic coating that creates a mirror‑like appearance from the exterior while maintaining outward visibility from the interior. It reflects solar radiation for heat rejection.
Q2: What is the difference between MSVD and pyrolytic reflective glass?
MSVD (soft coat) offers more colours and higher performance but must be used in an IGU. Pyrolytic (hard coat) is more durable and can be used as monolithic glass but has limited colour range.
Q3: Can reflective glass be tempered?
Yes. MSVD reflective glass can be tempered after coating with care. Pyrolytic reflective glass tempers like standard glass.
Q4: What colour is most popular?
Blue and silver are the most specified colours globally. Gold is popular for prestige projects in Asia and the Middle East.
Q5: Does reflective glass provide privacy?
Yes. During the day, the mirror effect provides excellent privacy. At night, interior lighting reverses the effect – blinds or curtains are recommended.
Q6: Are there reflectivity restrictions?
Yes. Many cities limit exterior reflectivity to ≤30%. Silver (35%) and gold (40%) may require variances. Always check local planning requirements.
Q7: What is the maximum size for reflective glass?
Up to 3550 × 18100 mm for MSVD coated glass. Pyrolytic reflective glass is available up to 3660 × 21400 mm.
Q8: What certifications do you provide?
EN 9096, ASTM C1376, CE, CCC, SGS.
Q9: What is the lead time?
Standard reflective IGU: 5–7 weeks. Jumbo sizes: 7–9 weeks. Custom colours: 8–10 weeks.
Q10: Can reflective glass be combined with Low‑E coating?
Yes. Some reflective coatings already incorporate Low‑E function. Alternatively, a separate Low‑E coating can be applied to the inner lite of the IGU.
