Is it better to ask broken bridge aluminum doors and windows 60 or 70? For this problem, we must first choose the corresponding model where the customer wants to purchase broken bridge aluminum. If it is in an outdoor environment, there is no need to buy broken bridge aluminum, and buying aluminum alloy or plastic steel can meet the demand.
We all know that broken bridge aluminum is an upgraded version of aluminum alloy, whose main features are heat preservation, sound insulation and sealing performance. If it is used indoors or on the balcony and requires sound insulation and temperature difference, it is necessary to buy broken bridge aluminum.
Currently, there are many categories of broken bridge aluminum, which are mainly distinguished by models such as 55, 60, and 70. So what do 60 and 70 mean? The following small series introduce one by one.
First, let's look at the basic structure of broken bridge aluminum (as shown in the following figure)
We can see: 1. Hollow glass. 2 Customer seal silicone. 3. Customer seal pad. 4. Customer sealing tape. 5. Glass gasket. 6. Wood layering. 7. Pure wooden craft's fan profiles. 8. Main sealing strip. 9. Water tape. 10. Hardware. 11. Sealant strip within waterproof tank. 12. The second sealing strip. 13. Aluminum alloy Rhone. 14. Pure wooden frame profiles. 15. Rhone sealant.
In fact, the 60 and 70 models are generally domestic manufacturers, in order to take the data of the frame thickness of the product as the difference between the product models. 60 is the thickness of the frame body 60mm, 70 is the thickness of the frame body 70mm, and there are different technical differences when the product is designed.
Size thickness: 60 is a profile design with a wall thickness of 1.4mm, with pa66 nylon insulation strip with a width of 20mm and a frame thickness of 60mm. 70 is a three-cavity heat insulation profile with a wall thickness of 1.6mm, combined with 35.3mm multi-cavity PA66 heat insulation strip, the frame thickness is 72mm, with three layers of all-steel hollow sound insulation glass, the overall performance can reach 8 levels of heat insulation and 7 levels of water tightness, air tightness Level 8, wind pressure resistance level 6, sound insulation level 4.
Different channel density designs: 60 series generally has three seal or six seal designs. 70 series ten seal design.
Different glass accessories: 70 series profiles use 5 22 5 (two 5mm thick glass, the air layer in the middle is 22mm) hollow glass, 60 series profiles use 5 12 5 (two 5mm thick glass, the air layer in the middle is 12mm) hollow glass. In terms of sound insulation and cold insulation, 70 series is much higher than 60 series.
Price difference: due to different craft and material sizes, the prices of the two series vary greatly, and the price of 70 will definitely be high.
Different hardware accessories: 70 series is mostly used for wall surfaces, which require higher hardware accessories and wind resistance. Stronger on firmness.
Through the comparison listed above, I believe everyone has an understanding of the differences between 60 and 70 series. However, when you choose to buy, you still don't know whether 60 is better or 70 is better. Here, I will introduce some knowledge to you, if it is an office window. (As shown in the figure)
If it is used in the environment of the wall, 70 series should be used. Another is that it is better to use 70 series in balcony sealing environment. If it is an ordinary family indoor insulation environment, the use of 60 series can completely meet the requirements, after all, the price of 70 will be much higher. Through the above instructions, I believe you have your own choice in choosing which series to buy.
