Sandwich glass is processed with special technology under high
temperature and high pressure by adding one or more layers of
Polyvinyl Butyral (PVB) with tough and strong binding between or
among two or more glass layers. For the great binding performance,
sandwich glass could stop external force attack and the chips will
bind with PVB after breakage to avoid making harm to person. And
sandwich glass could still resist attack from wind and rain in
In order to guarantee the quality of sandwich glass, PVB film could
be imported from Du Pont of USA or Sekisui of Japan to make
sandwich glass. We also have Chinese famous brand PVB for laminated
glass with high quality and transparency. Sandwich glass can be
further processed into tempered laminated glass, glass with holes,
into insulating glass etc.
Sandwich glass is widely used for bullet proof, burglar-proof,
showcase, counter, aquarium, skylight, long corridor, sidelite,
Max. Size: 2440mm*6000mm
Min. Size: 300mm*300mm
Thickness of PVB film: 0.38mm-3.04mm
Thickness(mm) 6.38mm, 8.38mm, 10.38mm, 10.76mm, 12.76mm, etc
Colors of PVB film transparent, milk, blue, dark grey, light green,
Standard: EN 12543; ANSI Z 97.1 200; BS 6206
Sandwich glass advantages:
Sound reduction, the special laminated construction could reduce
sound spread effectively, then that function make laminated glass
has great performance in sound control, PVB also could filter and
absorb ultraviolet (UV) rays 99.5% at least, so laminated glass
could reduce the cost of electronic power and save energy, the
effects will be better if you adopt special PVB interlayer.
Features of Sandwich glass as following:
1. Extremely high safety: The PVB interlayer withstands penetration
from impact. Even if the glass cracks, splinters will adhere to the
interlayer and not scatter. In comparison with other kinds of
glass, laminated glass/sandwich glass has much higher strength to
resist shock, burglary, burst and bullets.
2. Energy-saving building materials: PVB interlayer impedes the
transmission of solar heat and reduces cooling loads.
3. Create aesthetic sense to buildings: Laminated glass/sandwich
glass with a tinted interlayer will beautify the buildings and
harmonize their appearances with surrounding views which meet the
demand of architects.
4. Sound control: PVB interlayer is an effective absorber of sound.
5. Ultraviolet screening: The interlayer filters out ultraviolet
rays and prevents the furniture and curtains from fading
