Entry-Level Safety Glass for Windows, Doors & Balcony Railings
6.38mm laminated glass (also known as 3+0.38+3 PVB laminated glass) is the most cost‑effective safety glazing option for residential and light‑commercial applications. Two 3mm panes of float glass are bonded together with a 0.38mm polyvinyl butyral (PVB) interlayer under heat and pressure. When the glass breaks, the PVB holds the shards in place – preventing fall‑through injuries and providing basic security against forced entry.
At just ~15.2 kg/m², it is lightweight, easy to handle, and suitable for projects where budget is the primary concern but safety compliance cannot be compromised. It meets EN 14449, CE, ASTM C1172, and AS‑NZS 2208 standards.

6.38mm laminated glass is widely specified for double‑hung, casement, and sliding windows in apartment buildings and housing developments. The PVB interlayer provides UV protection (blocks >99% of UV rays) and reduces sound transmission by ~32 dB.
For fully‑framed glass doors, 6.38mm offers adequate impact resistance while keeping hardware costs low. It is a common choice for French doors, patio doors, and office partition doors.
When the glass is fully supported by a frame (aluminum or steel), 6.38mm laminated glass serves as a safe, affordable infill panel. It prevents fall‑through even if the glass cracks.
Office dividers and room partitions benefit from the clean look and safety of laminated glass. The PVB interlayer also dampens noise, making it suitable for meeting rooms.
For small, fully‑framed skylights, 6.38mm laminated glass provides basic overhead safety. Note: For larger or unframed skylights, 8.38mm or thicker is recommended.
Lightweight and shatter‑resistant, 6.38mm laminated glass is an excellent alternative to horticultural glass for hobby greenhouses.
Museums, retail stores, and galleries use 6.38mm laminated glass for display cases where safety and UV protection are required without excessive weight.

Q1: Can 6.38mm laminated glass be cut after lamination?
No. Once laminated, the glass cannot be cut, drilled, or edged. All processing must be done before lamination.
Q2: Is 6.38mm laminated glass strong enough for a balcony railing?
Yes, when fully framed and supported. For frameless balustrades, we recommend 8.38mm or thicker.
Q3: What is the weight of 6.38mm laminated glass?
Approximately 15.2 kg per square meter. A 1 m × 2 m panel weighs about 30 kg.
Q4: Can I get 6.38mm laminated glass with tempered glass?
Yes. You can specify “tempered laminated” – each pane is tempered before lamination for added strength.
Q5: What PVB colors are available?
Clear, milky white, bronze, grey, blue, green, and custom RAL colors on request.
Q6: Does 6.38mm laminated glass block UV?
Yes, it blocks over 99% of UV radiation, protecting interiors from fading.
Q7: What is the maximum size you can produce?
2550 mm × 7800 mm. Larger sizes may be possible – please inquire.
Q8: How does 6.38mm compare to 8.38mm?
6.38mm is thinner, lighter, and cheaper. 8.38mm offers about 1.6× the stiffness and better impact resistance for larger spans.
