A premium thermally insulated hinged aluminium system combining concealed sash design, minimal visible aluminium and high certified performance for contemporary residential and architectural projects.
Only 67 mm of visible aluminium for a cleaner façade, increased natural light and refined minimal architecture.
ALUMIL SMARTIA S77 PHOS is a premium thermally insulated hinged system developed for contemporary architecture where minimal aluminium sightlines, natural light and high performance are equally important.
The concealed sash significantly reduces the visible aluminium surface, creating a clean exterior appearance while maintaining the insulation, security and weather performance required for demanding residential and commercial projects.
The concealed sash creates an exceptionally clean external appearance with only 67 mm of visible aluminium, increasing the glazed surface and allowing more natural light into the interior.
Concealed fittings further reinforce the minimal character of the system by keeping functional components discreet and visually integrated.
A minimum visible central adjoining profile of only 69 mm enables elegant double-sash constructions with reduced aluminium interruption.
The narrow central section allows two-leaf windows and balcony doors to maintain the same refined architectural language as single-sash configurations.
A specially designed 13 mm low threshold provides easier passage while maintaining the contemporary design and functional character of the system.
Suitable for balcony-door configurations and projects requiring improved accessibility for children and people with reduced mobility.
The concealed-sash design reduces the visible aluminium face to only 67 mm, increasing transparency and allowing the glass to become the dominant architectural element.
The refined central adjoining profile allows double-sash constructions to retain slim proportions and balanced architectural sightlines.
Hidden fitting solutions minimise visible mechanical elements and reinforce the clean interior and exterior appearance of the window.
Glazing from 30 to 45 mm provides flexibility for high-performance thermal, acoustic, security and solar-control glass configurations.
Core dimensions and certified performance values for architectural specification and technical project evaluation.
Concealed-Sash Thermally Insulated Hinged System
Performance values depend on construction dimensions, glazing, hardware configuration, selected profiles and project-specific requirements. Acoustic performance depends on the selected glazing and complete window configuration.
40 mm polyamide thermal breaks, ALUMIL Energy Bar technology and additional insulating foam work together to reduce heat transfer through the aluminium frame.
A three-level perimeter sealing system using EPDM and foam EPDM gaskets provides high protection against air, rain and demanding weather conditions.
Appropriate glazing configurations combined with the high-performance frame can provide sound reduction levels of up to 42 dB for enhanced interior comfort.
The system can achieve RC3 burglar-resistance performance, providing an additional level of protection for demanding residential and architectural applications.
A complete range of tilt-and-turn configurations, including low-threshold, fixed-light, fanlight, pivot and concealed-sash solutions.
Availability and maximum dimensions may vary according to the selected profiles, glazing, hardware and project-specific requirements.
