Hello everyone, I'm Xiaobian. Today, I will introduce you to the sound insulation and heat insulation glass. The following content is organized by the editor, and the relevant content is for reference.insulating glassThe insulating glass 12a means that the middle dividing bar is 12 mm, and 20a means that the middle dividing bar is 20 mm. The larger the gap in the middle, the better the sound insulation effect, so the sound insulation effect of 20a is better! The thickness of the air layer determines the height of the insulation coefficient of insulating glass. 20A insulating glass has better sound insulation effect than 12A insulating glass.Insulating glass was invented by American citizens in 1865. It is suitable for good heat insulation, sound insulation and beautiful appearance. It is a new type of building material that can reduce the weight of buildings. It uses two pieces (or three pieces) of glass, high-strength and high-air tightness composite adhesive to bond glass sheets and magnesium-aluminum alloy frame containing desiccant, which is a high-performanceSound and thermal insulation glass.The performance of most insulating glass is better than that of ordinary double-layer glass, so it is recognized by countries all over the world. Insulating glass refers to a glass product that effectively supports two or more pieces of glass to be evenly isolated, and the periphery is bonded and sealed to form a dry gas space between the glass layers. The main materials are glass, aluminum alloy separator, corner bolt, butyl rubber, polysulfide rubber, and desiccant.If you want to know more about the industry information of sound insulation and heat insulation glass, please log in to our official website and we will bring you more practical knowledge. //qjsoft.js.cn
