Details can be seen in the real chapter. Hidden drainage of doors and windows eliminates the "hole" panic in the home

In the current era where home aesthetics and practical needs are equally emphasized, the "invisible function" of doors and windows often affects the upper limit of living quality.
Hidden drainage through doors and windows, not ostentatious in appearance, silently safeguards indoor dryness, wall safety, and spatial aesthetics, responding to users' deep expectations for ideal homes with an "invisible heart".
Breaking through cognitive misconceptions

When it comes to hidden drainage, many people may mistakenly think that the drainage holes are just hidden, but this precisely ignores the core value of this design.
The hidden drainage of Passive doors and windows is not just a simple appearance decoration, but a comprehensive upgrade in drainage efficiency, anti backflow ability, and sealing performance by optimizing the structure of door and window profiles and reconstructing drainage paths while hiding drainage holes.

It not only solves the problem of traditional drainage holes being exposed and affecting aesthetics, but also avoids the hidden danger of water seepage caused by poor drainage. By relying on technological innovation, it achieves a balance between functionality and aesthetics, achieving a perfect unity of invisibility and practicality.
Analyze design logic
Hidden drainage is not just a simple appearance upgrade, but a quality leap from "passive drainage" to "active protection". The significant advantage of concealed drainage for Passive doors and windows stems from its scientific structural design logic.

The concealed drainage system with a central guide adopts dedicated guide pipes and guide fixing components. After rainwater enters the profile, it will naturally guide along the preset concealed channel. The drainage pipe is vertically downward with high vertical gravity pressure, making drainage smoother and avoiding water accumulation.

The drainage outlet shall be set reasonably, and the principle of air pressure difference shall be used to prevent the outdoor wind and rain from flowing back. Even in the case of rainstorm, the one-way drainage of rainwater can be ensured, and the drainage capacity is more stable. There are no exposed "holes" on the surface to prevent anti wind effects and mosquitoes from flying in.
The drainage channel is deeply integrated with the door and window sealing system, which not only does not damage the overall airtightness, but also maintains the integrity of the profile appearance through the invisible design of the drainage holes, without grooves or damage, making the door and window lines more concise and smooth.
Returning to Home Value
The value of hidden drainage should ultimately return to the actual experience of home life, transforming the comfort of "moistening things silently" into a perceptible living quality for users.

The design without exposed drainage holes makes Passive doors and windows more coordinated with walls and home styles, especially suitable for high-end decoration styles such as minimalism and light luxury, avoiding the embarrassment of "holes damaging the overall feeling".
Efficient drainage and anti backflow capabilities directly reduce problems such as wall mold and floor deformation caused by rainwater leakage, extending the service life of home decoration.

Concealed channels are less prone to dust accumulation and do not require frequent cleaning of exposed holes, making living more worry free.

When home choices shift from meeting basic needs to pursuing detailed quality, hidden drainage has become an important indicator.
Between visible beauty and invisible practicality, Passive doors and windows achieve a more comfortable living state and find the perfect balance of ideal home.
