Laminated glass is a combination of two or more glass sheets with one or more interlayers of plastic (PVB) or resin. In case of breakage, the interlayer holds the fragments together and continues to provide resistance to the passage of persons or objects. This glass is particularly suitable where it is important to ensure the resistance of the whole sheet after breakage such as: shop-fronts, balconies, stair-railings, roof glazing.
There are two types of laminated glass: PVB and resin laminated glass: PVB laminated glass is two or more sheets of glass which are bonded together with one or more layers (PVB) under heat and pressure to form a single piece. Resins laminated glass is manufactured by pouring liquid resin into the cavity between two sheets of glass which are held together until the resin cures.
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 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 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 effec
