Summer is coming to an end, and autumn rain is coming one after another. Every time this time comes, it is also a big test for the watertight performance of doors and windows. If the doors and windows have defects of water leakage and air leakage, the house is prone to moisture on the walls, slippery floors, and damp furniture.The ensuing "wet" feeling will haunt us, so we can't wait to smash the doors and windows and reinstall ! 

Doors and windows, as warriors facing the wind and rain, are the first line of defense in the "anti-moisture war". Therefore, it is very important to choose a window with good watertight and airtight performance!

Let me teach you a few tips for buying doors and windows, and bid farewell to the indoor humidity in the rainy season!

The cavity design and sealing form of the profile structure have a great influence on the waterproof performance of the window sash.Baydee door and window profiles have independent drainage cavity and internal and external dislocation drainage structure, flooding slope design；Outside the window, there is a unique lower drainage structure formed by the combination of the window sill plate and the sub-frame, which can effectively prevent the infiltration of rainwater and drain the accumulated water smoothly.

A good sealing strip can effectively block the intrusion of outdoor rainwater, so carefully check the density of the sealing strip before purchasing doors and windows. This is a powerful tool to improve the water tightness and air tightness of doors and windows.

Baydee doors and windows use EPDM sealing strips and patented water-swelling strips. The strips swell in water, have good toughness, are resistant to aging and are not easily deformed, and can well block the intrusion of rainwater.

The assembly process of doors and windows has a great influence on the sealing of doors and windows. If the assembly structure is unreasonable, the gap of the window frame will be too large, causing the doors and windows to leak air and rain.

Baydee doors and windows adopt the overall welding technology.，Whether it is 45° or 90°, the group angle accuracy is very high, the appearance is smooth and smooth, without any gaps, and the whole window is firmer, more sealed, and more rain-proof.

Check whether the aluminum spacers between the insulating glass layers can be bent as a whole, the sealing at the splices is not in place, and whether the interior is filled with molecular sieves, because this can improve the sealing performance of doors and windows and effectively prevent the insulating glass from being damaged in wet weather.

The insulating glass aluminum spacer of Baydee doors and windows adopts a fully automatic integrated bending process, and there is only one splicing point.，Effectively prevent water molecules from entering; the hollow aluminum spacer is filled with molecular sieves, which can effectively remove the moisture in the aluminum spacer.
