70 Casement Window System – Precision Engineering Meets Lasting Performance
The 70 Casement Window System is more than just a window—it is a high-performance architectural solution designed for modern living. Engineered with advanced sealing technology, premium hardware, and thermal insulation, this system meets the needs of architects, contractors, and homeowners who demand uncompromising quality. Whether for a single-family home renovation or a large-scale residential development, the 70 Series delivers long-term reliability, superior comfort, and energy efficiency.
Structural Strength & Stability
Unlike conventional frames that weaken over time, the 70 Casement Window System uses patented corner key assemblies with injected sealant bonding, ensuring a molecular-level structural connection. This prevents frame distortion, water infiltration, and air leakage, providing decades of stability even under extreme weather conditions. For developers, this means reduced long-term maintenance costs and enhanced customer satisfaction.
Premium Hardware for Smooth Operation
Every component in the system is chosen to guarantee lasting performance. Customers can select imported European hardware brands such as Siegenia, Roto, or GU, or high-grade domestic alternatives that match international standards. Hinges, handles, and locking systems are tested for over 20,000 operating cycles, ensuring smooth, silent, and effortless operation for years to come. The system combines elegance with engineering precision, suitable for both residential and commercial projects.
Triple-Layer Sealing System
The 70 Casement Window System goes beyond single or double sealing by incorporating EPDM gaskets at three key contact points. This triple-layer protection provides:
Soundproofing up to 42 dB, ideal for urban apartments or roadside properties.
Excellent airtightness and watertightness, preventing drafts and leaks during heavy rainfall.
Energy efficiency, minimizing thermal transfer, and helping reduce HVAC costs by up to 30%.
These advantages position the system as a soundproof casement window solution and an energy-efficient window system for eco-conscious projects.
Flexible Opening Modes for Versatility
Different buildings require different ventilation and access solutions. The 70 Casement Window System offers multiple opening modes:
Tilt & Turn (Inward): Enables secure micro-ventilation, child-safe tilting, and easy interior cleaning.
Side-Hung (Outward): Provides unobstructed airflow and a sleek appearance.
This versatility makes it ideal for high-rise apartments, villas, office buildings, and boutique projects where both safety and convenience are critical.
Thermal Break Technology for Cold Climates
For projects in frost-prone or northern regions, the system integrates advanced thermal insulation features:
34mm Wide Thermal Break Bars imported for maximum insulation.
Chamber-filled frames and warm-edge spacers to reduce condensation and heat loss.
Compliance with ENERGY STAR® Northern Zone standards makes it one of the most reliable thermal break casement window systems available.
These innovations ensure warm, condensation-free interiors, even in sub-zero conditions.
Scalable Solutions for Every Project
From luxury villas to 500-unit residential complexes, the 70 Casement Window System delivers consistent quality at scale. Bulk procurement is streamlined with unified components, enabling faster installation and reduced logistical complexity. Developers appreciate the cost efficiency and reliability, while end-users enjoy the flawless finish and comfort.
