By Hemant Sharma Glass plays a vital role in modern architecture, interiors, and automobiles. From residential windows to commercial buildings and vehicles, the demand for high-quality glass has increased in India. Among the many brands, Saint-Gobain is one of the most trusted names globally, known for its premium quality, durability, and innovative glass solutions.
However, because of its popularity, fake or duplicate glasses are sometimes sold in the market under the Saint-Gobain name. For buyers whether homeowners, builders, or architects knowing how to identify original Saint-Gobain glass is very important to ensure value for money and safety.
Why Choose Saint-Gobain Glass?
Saint-Gobain is a French multinational company with a strong presence in India. Its glass products are used in:
- Architectural projects (windows, facades, partitions)
- Interiors (mirrors, designer glass, shower enclosures)
- Automotive glass (cars, buses)
The brand is known for:
- High clarity and transparency
- Energy-efficient and heat-resistant options
- Safety and strength (tempered, laminated glass)
- Long-lasting durability
How to Identify Original Saint-Gobain Glass
1. Brand Marking / Logo
- Original Saint-Gobain glass sheets usually have a small etched logo or brand name in one corner.
- The marking is permanent and clear, not like a sticker that can be peeled off.
- Fake or local glasses may use stickers or no marking at all.
👉 Always check the etched logo before purchase.
2. Quality of Transparency
- Saint-Gobain Glass: Offers high clarity, less distortion, and uniform thickness. When you look through it, objects appear true to size and color.
- Ordinary Glass: May show slight waviness, greenish tint, or uneven thickness.
👉 Test by placing a paper with straight lines behind the glass. Original Saint-Gobain glass will show lines clearly, while cheap glass may distort them.
3. Edge Finishing
- Original Saint-Gobain glass has smooth, well-finished edges.
- Duplicates may have rough, chipped, or uneven edges, indicating poor cutting and processing
4. Sound Test
- Tap gently on the glass.
- Saint-Gobain Glass: Produces a clear, crisp ringing sound, indicating density and purity.
- Low-quality glass: Produces a dull or uneven sound.
5. Thickness and Strength
- Saint-Gobain provides glasses in standardized thickness (from 3mm to 19mm) depending on use.
- They also offer specialized glass like tempered or laminated, which is much stronger and does not shatter easily.
- Ordinary glasses may be thinner, uneven, and break quickly.
6. Heat and UV Protection
- Many Saint-Gobain products (like Sun-Ban, Cool-Lite, Solar Control glass) are designed to reduce heat and block UV rays.
- To test, stand behind the glass in sunlight:
- Saint-Gobain Glass: You will feel less heat and glare compared to ordinary glass.
- Local Glass: Allows more heat and harsh light inside.
7. Documentation & Warranty
- Genuine Saint-Gobain dealers provide bills, product codes, and warranty certificates.
- If the seller hesitates to provide documentation, it may not be original.
Where to Buy Original Saint-Gobain Glass in India
- Authorized Saint-Gobain showrooms and distributors
- Certified dealers listed on the official Saint-Gobain India website
- Trusted hardware or interior design stores
Avoid buying from unverified local vendors who may sell ordinary glass under the brand name.
