Minimal Thermally Insulated Hinged System

ALUMIL SMARTIA
S77 PHOS

A premium thermally insulated hinged aluminium system combining concealed sash design, minimal visible aluminium and high certified performance for contemporary residential and architectural projects.

67

Only 67 mm of visible aluminium for a cleaner façade, increased natural light and refined minimal architecture.

01 / Overview
Minimal Architecture

Concealed sash.
Maximum natural light.

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.

Applications
  • Luxury residential projects
  • Contemporary villas
  • Premium apartments
  • Hotels & hospitality projects
  • Low-energy buildings
  • Architectural renovation projects
02 / Solutions
Architectural Solutions

Minimal appearance.
Flexible functionality.

01 — Concealed Sash

Minimal Window

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.

02 — Slim Mullion

Refined Central Profile

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.

03 — Low Threshold

Accessible Transition

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.

03 / Design
Architectural Design

Less frame.
More architecture.

01

67 mm Visible Aluminium

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.

02

69 mm Central Mullion

The refined central adjoining profile allows double-sash constructions to retain slim proportions and balanced architectural sightlines.

03

Concealed Hardware

Hidden fitting solutions minimise visible mechanical elements and reinforce the clean interior and exterior appearance of the window.

04

Double & Triple Glazing

Glazing from 30 to 45 mm provides flexibility for high-performance thermal, acoustic, security and solar-control glass configurations.

Thermal & Weather Performance

Hidden technology.
Serious performance.

Advanced Thermal Insulation

40 mm polyamide thermal breaks, ALUMIL Energy Bar technology and additional insulating foam work together to reduce heat transfer through the aluminium frame.

Three-Level Sealing

A three-level perimeter sealing system using EPDM and foam EPDM gaskets provides high protection against air, rain and demanding weather conditions.

06 / Comfort
Security & Everyday Comfort

Quiet inside.
Protected outside.

Acoustic Comfort

Appropriate glazing configurations combined with the high-performance frame can provide sound reduction levels of up to 42 dB for enhanced interior comfort.

RC3 Security Capability

The system can achieve RC3 burglar-resistance performance, providing an additional level of protection for demanding residential and architectural applications.
