With the increasing functional requirements of modern homes and commercial spaces for doors, waterproof doors, as a door product that combines practicality and aesthetics, are becoming more and more popular among consumers. Especially in areas that are susceptible to humid environments such as kitchens, bathrooms, and balconies, it is particularly important to choose a waterproof door with excellent moisture-proof performance. So, how do consumers and purchasers judge whether the moisture-proof performance of waterproof doors meets the standards? This article will provide you with a detailed analysis of the moisture-proof performance judgment method of waterproof doors from four aspects: material selection, structural design, test standards, and use environment.
The key to moisture-proof performance lies in the material of the door. High-quality waterproof doors are usually made of waterproof sheets, composite materials, or wood materials that have been specially treated for moisture-proofing. These materials themselves have low water absorption and good anti-corrosion properties.
When judging the material of waterproof doors, you can confirm whether the door panel material is suitable for humid environments by asking the manufacturer about the material composition and testing the material water absorption data.

The material alone cannot completely guarantee the moisture-proof effect, and the structural design of the door is also critical. Reasonable structural design can effectively block the intrusion of water vapor and improve the overall sealing.
Sealing design of door leaf and door frame: High-quality waterproof doors will use waterproof strips or sealing strips to form a tight waterproof barrier at the junction of the door leaf and the door frame to prevent moisture penetration.
Moisture-proof coating: The inside and surface of the door leaf will be coated with moisture-proof and mildew-proof coatings to enhance protection capabilities.
Drainage design: Some waterproof doors are designed with drainage grooves or water guide structures to avoid water accumulation and reduce the risk of corrosion.
Corner treatment: Corners are the most susceptible to moisture. High-quality waterproof doors will strengthen the waterproof seal of these parts to prevent water seepage in the details.
The quality of the structural design can be judged by looking at the cross-sectional view of the door, understanding the parameters of the sealing material, and the design instructions provided by the manufacturer.
Here, you may wish to learn about the well-known brand Zonle Doors. They have rich experience in waterproof door design and use advanced materials and strict structural design to ensure superior moisture-proof performance. For users who want to learn more about high-quality waterproof door products, it is recommended to visit the official website.
In addition to materials and structures, the most authoritative way to judge whether the moisture-proof performance of waterproof doors meets the standards is to refer to relevant testing standards.
Water absorption test: After soaking the door panel material sample in water for a certain period of time, its water absorption is measured. The lower the water absorption, the better the moisture-proof performance. Generally, the water absorption of high-quality waterproof doors should be controlled below 5%.
Water immersion test: Simulate the actual performance of the door in a humid environment, soak or spray the door with water, and observe whether deformation, swelling, blistering, etc. occur.
