6.38mm - 12.38mm Clear PVB Laminated Safety Glass (Cut to Size / Stock Sheets)

|

 Product Description

Our Standard PVB Laminated Glass is the most versatile safety glazing solution for residential and commercial use. Comprising two layers of glass bonded with a tough PVB interlayer, it offers three key benefits:

1. Safety: Keeps intruders out and holds together if broken (Anti-theft & Injury-proof).

2. Sound Control: Significantly reduces noise pollution compared to single glazing.

3. UV Protection: Blocks 99% of harmful UV rays, protecting furniture from fading.

Popular Specifications (Stock Available):

• 6.38mm (3mm + 0.38 PVB + 3mm) - Best seller for windows.

• 8.38mm (4mm + 0.38 PVB + 4mm) - For larger panels.

• 10.38mm / 12.38mm - For partitions and shopfronts.

• Colors: Clear, Milky White (Opal), Bronze, Grey, Green.

 Comment & FAQ

Q1: What is the difference between PVB and SGP?

A: PVB is standard for most safety needs. SGP (SentryGlas) is much stiffer and clearer; if SGP glass breaks, it stands upright without collapsing, making it safer for frameless railings.

Q2: Can you drill holes for glass standoffs?

A: Yes, we precisely drill countersunk or straight holes before tempering and laminating to fit your mounting hardware perfectly.

Q3: What is the standard thickness for balcony glass?

A: Typically 13.52mm (6+1.52+6) or 17.52mm (8+1.52+8) tempered laminated glass, depending on building codes and wind loads.

Q4: How do you handle edge misalignment?

A: We use advanced alignment techniques during assembly to keep the offset <1mm, ensuring a smooth edge for frameless applications.

 Optional Surface

• SGP (SentryGlas): 5 times stronger and 100 times stiffer than PVB. Recommended for frameless exterior railings in high-wind areas.

• Translucent White (PVB): Provides privacy for balconies while allowing light to pass through.

• Colored Laminated: Custom colors available using Vanceva PVB interlayers.

|

 Testing Quality

• Boil Test: Samples are boiled for 2 hours to ensure no delamination occurs (meeting durability standards).

• Impact Test: Shot bag or pendulum tests to verify safety performance.

• Visual Inspection: 100% check for bubbles, dirt, or edge misalignment under strong light.
