How are “waterproof” doors and windows made?

If the doors and windows have defects of water leakage and air leakage, the house is prone to moisture on the walls, slippery floors, damp furniture, etc. The ensuing "wet" feeling will trouble us, so we can't wait to smash the doors and windows.

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!

Below, Crown will teach you a few tips for purchasing "waterproof" doors and windows, so you can say goodbye to the trouble of indoor humidity in the rainy season!

Profile structure

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

Choice of adhesive strips

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 sharp tool to improve the water tightness and air tightness of doors and windows.

Crown 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.

Door and window corner technology

The corner forming 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.

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

Insulating glass aluminum spacer

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 Fog and moldy.

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