[China Glass Network] How much better is the sound insulation effect of three-layer insulating glass than double-layer insulating glass? Men's sunglasses are cool. They design different frame shapes according to different faces of men. Each frame shows different personality charms. Highlight individuality, make the wearer light and comfortable, fashionable and steady. It is also a kind of glasses that can block the sun's light in the strong light protection of the eyes of the products can block ultraviolet and infrared, while the color of the external environment does not change, only light intensity changes, play the protection of the eye.

No increase to 50% and the sound insulation effect needs to be compared to the ambient noise such as outdoor noise is 105 decibels installed 5 + 12A + 5 hollow glass room can reach 65-75 decibels if installed 5 + 12A + 5 + 12A + 5 hollow glass indoor noise Can be reduced to 55-60 decibels == This effect is very obvious! The cost of double-layer laminated glass is 150-180 yuan, if the profile is another, 380 can be taken, your window may use broken bridge aluminum A window is a set of special accessories. The price is doubled by the price I said. Your bedroom window is expensive. The three-layer laminated glass + broken bridge aluminum can be won within 1000 yuan. The thickness of the three-layer glass is generally about 5+5+5+0.5+0.5=16MM. Why do you want three layers? It is impossible to have no gaps in the profile between the profiles. The increase in the sound insulation effect of the single-window three-layer glass is not as good as that of the single glass window + hollow glass window. The ideal way to increase the sound insulation is to A layer of single-glazed glass window, inside which is made of a glass window with insulating glass. When the New Year’s Eve is noisy, the sound outside is lighter than the ticking of the indoor alarm clock. The insulating glass is more afraid of moisture and fog, single glass window The outside water vapor, the double glass window compartment heat, the three glass double window insulation noise, this is the ideal layout.
What kind of aluminum profile is the three-layer hollow glass window, and how many millimeters is the thickness of the three-layer hollow glass hollow layer?
Do three glass windows, the profile is better to choose more than 65 profiles to ensure that the three-glass two-cavity space is larger than 10mm. The larger the spatial distance of the insulating glass, the better the thermal insulation and sound insulation. Because there is a desiccant inside the hollow glass that can adsorb water molecules. The gas is dry, and when the temperature is lowered, the inside of the insulating glass does not cause condensation, and at the same time, the dew point on the outer surface of the insulating glass is also increased. For example, when the outdoor wind speed is 5m/s, the indoor temperature is 20°C, and the relative humidity is 60%, the 5mm glass starts to dew at the outdoor temperature of 8°C, while the 16mm (5+6+5) insulating glass is under the same conditions. Condensation occurs only when the outdoor temperature is -2 °C, and 27 mm (5+6+5+6+5) three-layer insulating glass begins to dew at an outdoor temperature of -11 °C. Because the insulating performance of the insulating glass is better, the temperature difference between the two sides of the glass is larger, and the effect of cold radiation can also be reduced; when the outdoor temperature is -10 ° C, the temperature in front of the indoor single-layer glass window is -2 ° C and hollow. The temperature in front of the glass window is 13 ° C; in the same building structure, when the outdoor temperature is -8 ° C and the indoor temperature is 20 ° C, the 3 mm ordinary single-layer glass cold radiation area accounts for 67.4% of the indoor space, while the double layer is used. The insulating glass (3+6+3) was 13.4%. The use of insulating glass can improve the safety performance of the glass. In the case of using the original sheet glass of the same thickness, the wind-resistant strength of the insulating glass is 1.5 times that of the ordinary single-piece glass.
How many millimeters thick is the three-layer hollow glass hollow layer the same as the ordinary two-layer insulating glass?
1. The thickness of the hollow glass hollow layer is generally 6mm~20mm; in special cases, it is also larger than 20mm, but it is extremely rare; if the thickness of the hollow layer is less than 6mm, the sound insulation amount is almost the same as the single-piece glass of the same thickness. Therefore, the hollow layer has a small thickness of 6 mm. Second, the expression method of the insulating glass is a three-segment representation, such as: "5+9A+5", the "5" on both sides means that the thickness of the original piece of glass is 5mm; "A" is the English word for air (Air) The abbreviation "9A" means that the intermediate glass has a thickness of 9 mm. We are more common in the usual, with both 9A and 12A specifications. Third, the specifications of the original sheet glass are generally: 3mm, 4mm, 5mm, 6mm, 10mm and 12mm. For the original sheet glass of the same thickness, the larger the intermediate glass spacing, the larger the allowable larger area. 4. The insulating glass is made of two or more pieces of glass with effective support and evenly sealed and sealed at the periphery to form a dry gas space between the glass layers to achieve the heat preservation effect. It is an energy-saving glass, such as “5+â€. 9A+5" ordinary insulating glass is roughly equivalent to the insulation effect of 100mm thick ordinary concrete. 5. In addition to the heat insulation function, the insulating glass also has good optical performance, anti-condensation and good sound insulation function. Therefore, it is often used in buildings with high requirements for thermal insulation and sound insulation functions, such as hotels and residences. , hospitals, shopping malls, office buildings, etc., are also widely used in vehicles and ships and other means of transportation. 6. For more information on insulating glass, please refer to the national standard "Insulated Glass" (GB/T11944-2002).
The advantage of three-layer insulating glass, which is practical compared with double-layer insulating glass?
The three glasses are white and double-layered, and the sound insulation effect is much better than the ordinary hollow effect. Generally used in the three northeastern provinces or alpine regions, the sound insulation effect is much better than the ordinary hollow effect. Say practical, then it is certainly practical cheap double glazing <br> <br> hollow glass window A 6 + 12A + 6 What is the meaning?
The 2 sides are 6 mm transparent glass with 12 AIR (the abbreviation A of the air layer). The glass thickness is 6+6+12-=24-25 mm (the butyl rubber has a thickness).
