Tianjin glass curtain wall construction program for a?

1Definition and scope of application

The open frame glass curtain wall refers to the glass panels inlaid in the aluminum frame to become a curtain wall component surrounded by an aluminum frame, which will be set in the transverse beams to form the transverse beams and columns are exposed, aluminum frame compartmentalization of the obvious fa?ade of the glass curtain wall.

Applicable to civil buildings in the open frame glass curtain wall installation project.

2 Material Requirements

2.1 The curtain wall should use safety glass, open frame and glass panels must meet the design requirements of the material, type, grade, optical properties, specifications, color should be in accordance with the relevant specification requirements. Aluminum alloy profiles should be surface oxidation treatment. Glass appearance quality and optical properties should be in line with the prescribed national standards.

2.2 Rubber strips, rubber mats should have aging resistance and flame retardant performance test factory certificate, the size of the design requirements, no fracture phenomenon. Connectors, embedded parts, fasteners and other spare parts must meet the design requirements, and anti-corrosion treatment. Sealant should have factory certification and waterproof test records. Thermal conductivity of insulation materials, waterproof performance and thickness to meet the design requirements.

2.3 The insulating glass of the curtain wall should adopt double sealing. Insulating glass of open-frame curtain wall should use polysulfide sealant and butyl sealant.
