We know that fengaluminum has aluminum alloy doors and windows and series. Each door and window product has many different models, among which fengaluminum aluminium alloy sliding window has fengaluminum 789 and fengaluminum 788 models, it is also the two main models of Phoenix aluminum alloy doors and windows on the market. The following is a brief introduction to Phoenix aluminum 789 and Phoenix aluminum 788.
We know that fengaluminum has aluminum alloy doors and windows and series, each door and window product has many different models, among which fengaluminum aluminium alloy sliding window has fengaluminum 789 and fengaluminum 788 models, which are also the two main fengaluminum aluminum alloy door and window models on the market, the following is a brief introduction to two models: Phoenix aluminum 789 and Phoenix aluminum 788.
1. Fengaluminum 789 is an upgraded product of fengaluminum 788. The inner car window shade track of fengaluminum 789-type lower track is 5mm higher than that of 788-type, which is 65mm. This design makes it rain, it is more difficult for rain to splash into the room from the lower track. Especially when there is heavy rain, the owner does not need to worry that the rain will splash into the room from the lower track of sliding window, which is a better waterproof aspect of fengaluminum 789 than fengaluminum 788.
2. In terms of air tightness, fengaluminum 789-type sliding window upper and lower tracks are all arc tracks, which makes the combination of door leaf and upper track better, improves the sealing effect, and it is more difficult for internal and external air to form convection, this undoubtedly improves the energy saving and environmental protection performance of sliding window; The design of arc track makes the door leaf no longer shake inside and outside due to the gap with the upper track. However, the upper track of fengaluminum 788 adopts the existing track, and the sealing effect is not ideal, and there is indeed the problem of shaking the door leaf.
3. The difference between Phoenix aluminum 789 and Phoenix aluminum 788: the gap between Phoenix aluminum 789 glass and inner frame is no longer sealed by leather strap like Phoenix aluminum 788, but sealed by silica gel. The advantage of silica gel sealing is that it is not easy to age, not easy to fall off, not easy to deform, and the sealing effect is better. It can be said that if the leather strap seal is used, it is definitely not the real Phoenix aluminum 789 model. So if Phoenix aluminum 789 is better than Phoenix aluminum 788, is there a big difference in price? Compared with fengaluminum 788, the price of fengaluminum 789 is about 15-25 yuan/square meter, which is quite cost-effective.
The difference between fengaluminum 789 and fengaluminum 788: fengaluminum 789 profile 1.4mm thick translation window is an upgraded product of fengaluminum 788 profile, compared with its predecessor fengaluminum 788, 789 profile sliding window has not changed much in appearance, but careful people will find that fengaluminum 789 still has some slight changes compared with fengaluminum 788. It is these changes that make fengaluminum sliding window more airtight and waterproof than fengaluminum 788. Fengaluminum 789 has a high performance of sliding window. Based on fengaluminum 788 series, it has changed the original ordinary upper track of fengaluminum 788, but the same wide track as lower track, but there is not much improvement in practical application, because the stress of the window is lower track, the width of the upper rail only makes the appearance look much more beautiful.

Fengaluminum 799 has a high performance of sliding window, which is also based on fengaluminum 788 series. There is a big change in double-layer glass. The hollow specification of fengaluminum 788 is 5mm 6A 5mm, the specification of the hollow glass of fengaluminum 799 is 5mm 9A 5mm, but the double-layer glass of fengaluminum 799 almost becomes a plane with the hand-drawn aluminum alloy, and the glass of fengaluminum 788 is slightly recessed a little bit, it is not flush with the material.
