Broken bridge aluminum doors and windows and 90 series aluminum alloy which high prices
90 series of square meters of aluminum alloy content is likely to be higher, broken bridge aluminum aluminum alloy content is relatively small, but because the broken bridge aluminum added insulation, the unit price is high, so it is not necessarily 90 series of expensive , The other window of the cost depends on the hardware used (that is, such as opening the use of locking institutions, transmission, etc.) push and pull open because of its different ways of opening, so its hardware is not the same, so the two are not too big Comparable.
Finally, the introduction of the flat window because of its open way to open, so the seal can be used EPDM tape seal, and the sliding window to open the fan to achieve through the sliding, the seal can only use the top to seal, the two seals Performance compared to the flat window of the sealing performance is much better, and doors and windows of the watertight, air tightness, insulation properties, sound insulation performance are fundamentally sealed, sealed bad, leaky water leakage, insulation will not be good, Of course, sound insulation will be significantly reduced, so if it is their own use to recommend the installation of flat window. Do not use sliding window.
Of course, there are sliding window using the tape seal, but because of the structure of the reasons, the tape to use self-lubricating function of the tape, the cost is high, so the market is rarely used engineering.
Broken bridge aluminum itself is also aluminum, there are 90 series, so the two can not be compared with each other.
However, the general market is usually referred to as the 90 series for the sliding window, and broken bridge aluminum refers to the flat window, and mostly 56 series or 65 series or close to the series.
Broken bridge aluminum is also aluminum,
The aluminum alloy profiles are divided into indoor and outdoor parts, the middle with a thermal insulation through the composite process to connect together to achieve broken bridge.
Aluminum alloy itself is a metal material, its thermal conductivity is very good, it means that its thermal insulation performance is poor, and the insulation material is PA66GF25, that is, the main component is nylon 25% glass fiber, the thermal performance is poor. Broken aluminum can be achieved aluminum insulation.
