How much better is the sound insulation effect of three layers of insulating glass than double layers of insulating glass?
The thickness of the three layers of glass is generally 5+5+5+0.5+0.5= about 16MM. Why three layers? It is impossible to have a gap between profiles without a little air leakage, single window 28mm triple glazing sound insulation effect is not as increased as single window + hollow window, the ideal way to increase sound insulation is to have a layer of single window glass outside, and then do a layer of glass window with hollow glass inside, the most noisy time of midnight on New Year's Eve, The sound outside is also lighter than the ticking sound of the indoor alarm clock, the insulating glass is more afraid of moisture fog, the single glass window blocks the water vapor outside, the double glass window blocks the heat in the room, and the three glass double Windows isolate the noise, which is the most ideal layout.
What kind of aluminum profile is the three-layer hollow glass window? How many millimeters thick is the three-layer hollow glass layer?
To do three glass Windows, it is best to choose more than 65 profiles so as to ensure that the three glass two cavity space is greater than 10mm hollow glass space distance, insulation and sound insulation is better, because there is a desiccant inside the hollow glass that can adsorb water molecules, the gas is dry, when the temperature is reduced, the inside of the hollow glass will not produce condensation phenomenon, at the same time, The dew point on the outer surface of the insulating glass will also rise.
For example, when the outdoor wind speed is 5m/s, the indoor temperature is 20℃, and the relative humidity is 60%, the 5mm glass begins to condensation when the outdoor temperature is 8℃, and the 16mm(5+6+5) insulating glass begins to condensation when the outdoor temperature is -2℃ under the same conditions. 27mm(5+6+5+6+5) three-layer insulating glass begins to condensation when the outdoor temperature is -11 ° C.
Due to the good thermal insulation performance of insulating glass, the temperature difference between the two sides of the glass is large, and the effect of cold radiation can be reduced. When the outdoor temperature is -10℃, the temperature in front of the indoor single-layer glass window is -2℃ and the temperature in front of the hollow glass window is 13℃. In the same house structure, when the outdoor temperature is -8 ° C and the indoor temperature is 20 ° C, the cold radiation area of 3mm ordinary single-layer glass accounts for 67.4% of the indoor space, while that of double-layer insulating glass (3+6+3) is 13.4%. The use of insulating glass can improve the safety performance of glass, in the case of using the same thickness of the original glass, the wind pressure strength of insulating glass is 1.5 times that of ordinary single glass.
Three layers of insulating glass How many millimeters thick is the insulating layer the same as ordinary two layers of insulating glass?
First, the thickness of the insulating glass hollow layer is generally 6mm ~ 20mm; In special cases, there are cases greater than 20mm, but it is extremely rare; If the thickness of the hollow layer is less than 6mm, its insulation volume is almost the same as that of a single piece of glass of the same thickness, so the minimum thickness of the hollow layer is 6mm.
Second, the representation method of insulating glass is three paragraphs, such as: "5+9A+5", the "5" on both sides indicates that the thickness of the original glass is 5mm; "A" is the abbreviation of the Chinese word Air, and "9A" means that the thickness of the middle glass interval is 9mm. We are most commonly seen in the usual, with 9A and 12A two specifications.
Third,The specifications of the original glass are usually: 3mm, 4mm, 5mm, 6mm, 10mm and 12mm, for the original glass of the same thickness, the larger the middle glass interval, the larger the maximum area allowed.
Four, insulating glass is composed of two or more pieces of glass to effectively support evenly separated and sealed around, so that there is a dry gas space between the glass layers, so as to achieve the insulation effect, is a kind of energy-saving glass, such as "5+9A+5" ordinary insulating glass, roughly equivalent to the insulation effect of 100mm thick ordinary concrete.
Fifth, in addition to the thermal insulation function, 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 function, such as hotels, residences, hospitals, shopping malls, office buildings, etc., and is also widely used in vehicles and other vehicles.
Advantages of three-layer insulating glass, which is practical compared with double-layer insulating glass?
Three glass is a double-layer hollow, temperature insulation and sound insulation effect is much better than ordinary hollow effect. Generally, it is used more in the three provinces of Northeast China or high-cold areas, and the temperature insulation effect is much better than the ordinary hollow effect. If anything, double glazing is cheap and practical.
