Dingyu-90 Flush-Frame, Double Inward-Opening System Window

一、Basic Product Performance Levels

二、Nine Key Advantages of the Product

1.Burglar-Resistant Locking Points: A multi-point interlocking locking mechanism provides multi-point security, enhancing home burglary protection.
2.Ultra-High-Precision Aluminum Profiles: High-precision extruded profiles ensure uniform gaps between frames and sashes, stable sealing, and smooth operation.
3.Advanced German Design Philosophy for Profiles and Accessories: The entire set of profiles and accessories adheres to German system window R&D standards, ensuring a scientifically sound and stable structure.
4.Standard hardware configuration with a load-bearing capacity of up to 80 kg; optional heavy-duty hardware supports up to 150 kg: Standard hardware supports 80 kg, and can be upgraded to heavy-duty hardware to support large glass sashes weighing up to 150 kg.
5.All gaskets are made of co-extruded EPDM foam; medium-pressure gaskets utilize a continuous bending process to minimize joints and enhance water and air tightness: Seamless, continuously bent gaskets ensure no weak points in the seal, providing superior wind resistance, rain protection, and sound insulation.
6.Profiles are paired with a floor-drain drainage system: Concealed floor-drain drainage ensures a clean and aesthetically pleasing appearance, with rapid drainage that prevents water accumulation and backflow.
7.Both inward- and outward-opening series feature a triple-seal system: a three-ring sealing structure provides multi-layered protection against wind, sand, rain, and outdoor noise.
8.The glass incorporates continuously bent warm-edge spacers: these spacers reduce temperature differences at the glass edges, minimize condensation, and optimize overall thermal insulation performance.
9.A 35.3mm-wide insulated spacer—exceeding the national standard of 24mm—provides superior thermal insulation. The spacer cavity can be optionally filled with PEX insulation material to further enhance thermal performance: the 35.3mm-wide spacer, with optional PEX insulation filling, delivers thermal insulation performance that significantly outperforms conventional thermal break windows.
