The SJ97 Double Inward Opening System Window Frame, developed by Jiangxi Tai’an Aluminum Co., Ltd., is a premium architectural aluminum profile designed for modern high-performance buildings. Combining strength, energy efficiency, and smart design, this system is ideal for residential and commercial projects demanding superior weather resistance, thermal insulation, and space-saving functionality.
Key Features
Robust Construction
Made from 6063-T5 high-grade aluminum alloy, precision-engineered for high structural integrity and wind load resistance (meets GB/T 8478-2020 Class 1).
Superior Thermal & Sound Insulation
24mm polyamide thermal break (PA66 GF25) reduces heat transfer, with a U-value as low as 1.8 W/(m²·K).
Triple-seal design (EPDM gaskets) ensures excellent air/water tightness (air leakage ≤0.5 m³/(m·h), water resistance ≥700Pa).
Space-Saving Dual-Inward Opening
Two sash panels open inward with adjustable 15°–90° tilt, allowing flexible ventilation control and easy cleaning.
Concealed heavy-duty hinges (optional EU-branded hardware) support 100,000+ open/close cycles.
Aesthetic Customization
Multiple finishes:
Powder coating (standard RAL colors)
PVDF fluorocarbon coating (UV/weather-resistant)
Wood-grain effect (sublimation transfer)
Smart Engineering
Modular design for fast installation and compatibility with smart home systems.
Reinforced corners with stainless steel screws for long-term durability.
