Laminated Glass, Safety Laminated Glass for Building Curtain Walls & Skylights

      In projects of building curtain walls, daylighting roofs and indoor partitions, glass materials provide daylighting, while safety stands as a key consideration for material selection. Ordinary monolithic glass breaks easily under external impact, with scattered fragments posing injury risks. For curtain walls and daylighting roofs on high-rise buildings, glass is installed above occupied areas, which imposes strict requirements on its safety performance upon breakage. Laminated glass is made by combining two or more glass sheets with an interlayer. When broken, glass fragments adhere to the interlayer to prevent flying debris. As safety laminated glass for building curtain walls and daylighting roofs, it meets glass application requirements for various construction components.

      Laminated glass is manufactured through high-temperature and high-pressure lamination of base glass sheets and an interlayer. PVB and other films are adopted as the interlayer. The glass and film are bonded together inside an autoclave to form an integrated structure. If the glass breaks, fragments stick to the interlayer and will not fall or splash. The interlayer features cushioning properties; when the glass suffers external impact, the film absorbs part of the impact energy to improve impact resistance. Even after breakage, laminated glass remains integral and retains its shielding function for a certain period, buying time for personnel evacuation. It can be fabricated with base glass sheets of varying thicknesses to satisfy strength requirements for different building sections. It can also be combined with tempered glass, coated glass and other types to meet diverse architectural design needs.

      For building curtain wall projects, glass panels on high-rise curtain walls are installed at height, leading to high replacement and maintenance costs. The safety condition of glass directly determines building safety. When laminated glass is used for curtain wall panels, fragments will not scatter upon breakage, lowering the risk of falling objects from height. Subjected to wind pressure and temperature fluctuations over long-term service, the laminated structure keeps the glass intact. Curtain wall projects impose strict specifications for glass. Laminated glass can be custom processed according to curtain wall panel dimensions to fit installation of unitized and framed curtain walls.

      For daylighting roofs and skylights, roof glass sits on the top of buildings. Falling fragments from broken glass endanger people underneath. Laminated glass stays integral after fracture and eliminates the hazard of falling debris, complying with safety standards for daylighting roofs. Exposed outdoors long-term, daylighting roof glass withstands sunlight, rain and temperature variations. The laminated interlayer features stable ageing resistance to maintain long-term service performance. Skylight glass can be combined with insulated structures to deliver both daylighting and thermal insulation, suitable for daylighting roof works of commercial and public buildings.

      For building guardrails, glass used on balcony balustrades, stair handrails and overhead protection sections must satisfy safety specifications. Fragments of broken laminated glass stick to the interlayer to reduce cut hazards for guardrail applications. Upon impact, the laminated structure holds the glass together and prevents extensive shattering. Glass for engineering guardrails can be custom cut to site dimensions for installation on residential balconies and guardrails of public buildings.

      For indoor partitions and interior curtain walls, laminated glass is applied to office partitions and shop glass walls. Its laminated structure enhances safety, keeping the glass stable when collision occurs in occupied spaces. The glass maintains transparency to preserve open sightlines, and interlayers are available in multiple colours and patterns to enrich interior decoration effects. Custom sizes for indoor partition glass are offered to fit renovation demands of office and commercial spaces.

      The production of laminated glass relies on a glass lamination processing line. Standardized control is implemented in every procedure, including raw glass cutting, film lamination, autoclave bonding and finished product inspection. Finished products undergo light transmittance and impact resistance tests to guarantee reliable performance. Multiple combinations of glass thicknesses, interlayer types and specifications are available to meet strength and safety requirements of different project sections, and custom dimensions based on construction drawings are supported. The products cater to procurement demands of curtain wall contractors, door & window manufacturers and architectural decoration enterprises.
