The 150 Series Side Pressure Sealing Door is a system-level door product designed for high-performance building applications, focusing on addressing the comprehensive needs of large-sized doors in terms of thermal insulation, sealing, structural stability, and long-term durability. Through multiple insulation layers, composite profile groove design, and side-pressure dynamic sealing technology, the Side Pressure Sealing Door significantly improves airtightness, watertightness, and sound insulation performance while ensuring door stability and safety. It is suitable for building projects with high demands on energy efficiency and user comfort.
Heat Shield MAX Insulation System: Through multiple layers of thermal insulation structures, it effectively reduces heat transfer, improving overall energy efficiency by over 30%, while maintaining stable performance under different climate conditions.
Syncreta Slot Collaborative Composite Groove Structure: Systematically integrates the insulation structure with the load-bearing structure, enhancing the door's insulation performance while significantly improving installation stability. Overall structural stability is increased by approximately 50%, and the service life is extended accordingly.
Dual-Pressure Sealing System: The side-pressure sealing structure creates multiple pressure levels during the closing process, achieving a tested airtightness of level 8, watertightness of 1000Pa, and sound insulation of 38dB, effectively blocking wind, rain, and noise interference.
AeroFrame Integrated Structural Design: The frame and load-bearing structure are integrally formed, achieving a minimalist facade while ensuring structural safety and long-term stability of the door even in large sizes.
Ultra-Seal Corner Technology: Specifically reinforces the corner areas of the door, preventing deformation and cracking during long-term use, ensuring that the entire system maintains stable sealing performance even after many years of use.

Projects requiring high door stability and long service life
In high-end building projects, doors are no longer just entry and exit points, but crucial components that directly impact energy consumption control, user comfort, and overall quality. Compared to ordinary flat-pressure doors, side-pressure sealing doors are more aligned with the long-term needs of high-end projects in terms of structural logic and performance.
The sealing performance is more stable and controllable. During the closing process, side-pressure sealing doors apply pressure laterally, ensuring even force distribution on the sealing strip, rather than relying on single-point or localized compression. This structure maintains stable airtightness, watertightness, and sound insulation performance even after long-term use, making it particularly suitable for high-end projects sensitive to wind pressure, noise, and climate change.
From a structural and durability perspective, side-pressure sealing doors are more suitable for large-sized, high-frequency use scenarios. The lateral force distribution is more reasonable, preventing the door from sagging or deforming. The opening and closing feel remains consistent even after years of use, which is especially important for public buildings and high-end residences.
In terms of design expression, side-pressure sealing doors typically adopt an integrated structure and concealed design, resulting in a cleaner visual appearance that doesn't compromise the overall facade integrity. For designers, this means that the design scheme is easier to maintain its integrity, and details are not compromised during the implementation phase.
In addition to internal testing, we collaborate with several third-party quality testing institutions to regularly conduct random inspections and performance verification of our windows and doors. The testing covers multiple aspects, including wind pressure resistance, water tightness, air tightness, thermal insulation, and weather resistance. The testing standards strictly adhere to GB/T 21086-2023 and EN standards, ensuring that our products meet high-level building requirements in both domestic and international markets.
