How To Choose The Suitable Insulating Glass?

Due to the different regions of use, the requirements for the performance and size of the insulating glass are also different. For example, adjacent street buildings require insulating glass to have good sound insulation performance; while in cold areas, insulating glass is required to have good heat insulation performance; low-rise buildings, hollow The area of the glass can be larger, and for high-rise buildings, because of the different wind pressure, the area should be smaller, and safety glass should be used as the substrate.

　　The thickness, specification, and variety of the selected substrate glass mainly depend on the wind pressure load in the use state.

　　Different installation methods also require different structures of insulating glass. The curtain wall uses hollow glass, the hidden frame and semi-hidden frame glass must use silicone structural glue, and the open frame installation can use polysulfide glue.

Different glass types and structures have very different energy-saving parameters. It is only relatively meaningful to evaluate whether a certain glass is energy-saving, and where and what kind of building it is suitable for, except that it is necessary to compare the shielding coefficient Sc and heat transfer coefficient of various glasses. In addition to the U value, the contribution of thermal insulation or thermal insulation to the total building energy saving in different regions should also be considered.

  Precautions:

　　 1. When using tinted glass, solar control coated glass, Low-E glass, etc., heat burst prevention design should be done.

　　 2. When the insulating glass is used in high-rise buildings, it is filled with inert gas to prevent the reduction of the life of the insulating glass and the distortion of the glass image due to the difference in air pressure. 〖Special attention: the impact of different altitudes on products〗

　　 3. Insulating glass can no longer be cut.

　　4. Neutral sealant should be used for the filling sealant between glass and glass, otherwise, it is easy to damage the stability of the original sealant of insulating glass due to the volatilization of molecular materials.

　　 5. The coated glass (sunlight control coated glass, low-emissivity coated glass) used on the same project facade should use the same process to prevent color differences caused by different production processes.

　　6. Comply with the requirements of "visible outdoor reflectance" of buildings under environmental conditions.

　　7. When the coated glass is used for bending steel products, please pay attention to the design of the radius of the product. If the radius is too small, glare is easy to appear.

　　 8. Please follow the corresponding technical specifications of the used part when using it.
