Which is better for aluminum alloy doors and Windows with thermal break, 80 or 70?

 

 

Two years ago, 90% of customers chose the 70 series for their doors and Windows. However, with the severe homogenization and fierce competition in the industry in the past two years, many door and window factories have developed the 80 series, 85 series, etc., providing customers with more and better choices. So, which is better for aluminum alloy doors and Windows with thermal break, 80 or 70? This topic cannot be generalized, as there are also many fake 80 series products in the market, which are what we often call fake 80 doors and Windows.

 

 

 

The fake 80 series is just tampering with the thermal break. Suppose the width of the thermal break of the 70 series doors and Windows is 2 centimeters, then the fake 80 series is to replace the 70 aluminum material with a 3-centimeter thermal break. Just by looking at it from the appearance, it is the 80 series. We call this type of door and window series the fake 80 series. Essentially, it is still made of 70 aluminum profiles. Just by tampering with the thermal break and widening it by 1 centimeter, it transformed into an 80 series door and window.

 

 

Here is the comparison between the genuine 80 series and 70 series that we are going to talk about. If it is a genuine 80 series door and window, it is superior to the 70 series in terms of heat insulation and heat preservation. In terms of sound insulation performance, there is not much difference between the two, and there is not much difference in sealing performance either. This is what a real door and window person tells consumers. From the perspective of a unscrupulous merchant, The 80 series is much stronger than the 70 series in terms of sound insulation, sealing, heat preservation and heat insulation. Thermal insulation and heat preservation: The 80 series, due to its wider profiles and larger thermal insulation cavity, theoretically offers better thermal insulation and heat preservation effects. It is particularly suitable for cold or hot regions and can effectively reduce energy loss caused by temperature differences between indoors and outdoors. Although the 70 series also has decent heat insulation performance, it may be slightly insufficient under extreme weather conditions. 2. Wind pressure resistance: As the width of the profile increases, the wind pressure resistance of 80 series broken bridge aluminum doors and Windows is usually stronger, making them suitable for high-rise buildings or areas with high wind pressure. The 70 series can also meet the basic needs in ordinary residences. 3. In terms of cost performance, both have their own merits. Although the 80 series has excellent performance, its price is relatively high. The 70 series, with its moderate price and excellent performance, has won the favor of many consumers.

 

 

To sum up, the 80 series and 70 series of broken bridge aluminum doors and Windows each have their unique advantages, and there is no absolute superiority or inferiority. When making a choice, consumers should conduct a comprehensive assessment based on their living environment, usage requirements and economic conditions. If you want to improve thermal insulation and heat preservation, the 80 series is definitely better than the 70 series. If you aim to enhance sound insulation and sealing, there is not much difference between the two under the same configuration.
