Chalco supplies custom aluminium casement window systems for residential buildings, apartments, hotels, commercial buildings, distributor projects and window companies. As part of our broader range of finished aluminum window solutions, we support thermal break profiles, glass matching, hardware customization, surface finishing and OEM project packaging based on drawings and window schedules.
Whether the project requires inward opening, outward opening, tilt-turn operation, fixed + casement window combinations, slim frames or flush sash appearance, we can recommend practical configurations based on project location, building type, performance requirements, market preference and delivery method.
The core value of an aluminium casement window is not only that the sash opens inward or outward. When closed, the locking points press the sash firmly against the sealing gasket. Compared with standard aluminum sliding windows, this compression-sealing structure provides a stronger basis for air tightness, water tightness and acoustic insulation.
Different projects have different requirements for casement windows. Through coordinated aluminum window design, the opening method, profile system, glazing, hardware, surface finish and appearance can be matched to the building type, climate and performance targets.
For standard projects and bulk supply
For thermal insulation and energy-saving projects
For facade projects requiring a consistent appearance
For modern buildings and wide-view designs
For European markets and safe ventilation
For daylighting with partial ventilation
After the opening type is confirmed, the depth and structure of the aluminum window profiles affect thermal insulation, glass loading, air and water tightness and overall performance. Frame depth should be selected according to window dimensions, glazing weight, performance targets and project standards.
The air tightness, water tightness, wind load resistance and long-term stability of aluminium casement windows are not determined by one parameter alone. They are achieved through profile structure, compression sealing, locking method, drainage path and fabrication accuracy. During project selection, buyers should confirm whether the whole-window structure matches local climate, wind load, operating frequency and installation conditions.
Thermal break strips and multi-chamber structures reduce heat transfer, lower thermal bridge and condensation risks, and suit energy-saving residential, apartment and cold-climate projects.
When the sash is closed, it compresses the EPDM gasket to form a continuous air- and water-tight seal, suitable for projects with higher acoustic, energy-saving and anti-leakage requirements.
Multiple locking points distribute force evenly across the sash, improving closing stability, sealing compression and wind load performance.
Concealed drainage, pressure-equalized drainage or water-air separation design can reduce water accumulation, backflow and leakage risks, making them suitable for rainy, coastal and high-rise projects.
Corner jointing, CNC machining and assembly accuracy affect whole-window strength, sealing continuity and long-term operating stability.
Chalco can match glass, hardware, sealing and surface finish options according to project positioning, budget, performance targets and target market, serving residential buildings, apartments, hotels, commercial buildings and distributor projects.

When closed, a casement window uses locking points to compress the sealing gasket, typically offering better air tightness, water tightness and thermal performance than a standard sliding window. Sliding windows are more suitable where opening space is limited or large horizontal movement is required. Project selection should consider climate, wind load, energy targets and usage method.
The whole-window U-value is affected by system depth, thermal break width, glass configuration, warm edge spacer, sealing structure and installation method. Project evaluation should consider window size, glass weight and local energy targets rather than only a single glass parameter.
They can be configured for coastal, humid or high-wind projects through weather-resistant surface finishes, sealed drainage structures, laminated glass and corrosion-resistant hardware. The final solution should be confirmed according to project wind load, salt-spray environment and testing requirements.
Tilt-turn systems are commonly used in European apartments, residential buildings, schools and hotels. They support safe ventilation, indoor cleaning and multi-function opening, making them suitable for buildings with higher air tightness and safety requirements.
Common options include insulated glass, Low-E glass, laminated glass, acoustic glass and triple glazing with two cavities. The final configuration should be confirmed according to system depth, opening sash size, performance targets and project budget.
Please provide the project location, window schedule or drawings, opening method, glass configuration, performance requirements, color and quantity plan so that the system configuration, quotation range and delivery plan can be confirmed.
