ATTENTION TO DETAIL
  • FLUSH INTERIOR DESIGN

    Achieve a perfectly flush appearance on the interior side of the window with a specially engineered frame.

  • FIRM & MINIMAL

    Precision-designed T-profiles with a reinforced core increase stability by just 0.39 inches (10 mm) — ideal for large openings and strong, modern architectural compositions.

Extra features
  • CONCEALED COMPONENTS

    They say form follows function — we took it further. By hiding functional elements, we let pure design take the spotlight.

  • HIDDEN HINGES

    Tilt or open the window without revealing a single hinge — subtle engineering at its finest.

  • MOVE WITHOUT LIMITATIONS

    The CE edition enables a full 180° opening, even with the concealed hinge mechanism.

  • HANDLES

    Handles so refined they elevate industrial design with a touch of sophistication.

THE TECHNOLOGY

We engineered it to set new standards in energy performance — secure, watertight, and uncompromising.
A complete, adaptable system designed so you can bring your vision to life.
Its performance across all factors that impact indoor comfort is exceptional and certified by the ift Rosenheim Institute in Germany.

THERMAL INSULATION

You’ll feel it on a cold night.
You’ll appreciate it on a hot day.
And you’ll truly love it when you see the savings.

Dynamic Image
  • 01. ELVIAL I² INNOVATIVE INSULATION TECHNOLOGY

    Our proprietary ELVIAL I² Technology is applied across all system profiles. By creating an additional insulation zone within the profile’s central chamber, it enhances thermal performance — improving the system’s Uf value by up to 38%.

  • 02. UP TO 1.65" INSULATING BARS

    Wide insulating bars, reinforced with 25% glass fiber and measuring up to 1.65 inches (42 mm), are applied to all system profiles. This provides superior thermal insulation that meets PASSIVE HOUSE Level I standards, ensuring exceptional rigidity and energy efficiency.

  • 03. CO-EXTRUDED GASKETS

    High-precision co-extruded gaskets are integrated throughout the central and perimeter areas of the window, optimizing isothermal flow. The addition of fin-shaped gaskets further reduces heat transfer to the glazing area, ensuring consistent interior comfort.

  • 04. FOAM INSULATING PROFILE

    A foam insulating profile is strategically placed along the perimeter of the glazing zone, minimizing thermal energy loss and maximizing overall performance.

THE SEALING SYSTEM

We designed the Advanced Sealing System to deliver complete waterproof protection for any structure.
Through precision vulcanization and seamless assembly, every part of the window becomes fully sealed and resistant to water infiltration.

  • 01. OPTIMAL 3-LEVEL WATERPROOFING

    A precision-engineered three-level waterproofing system featuring advanced EPDM and co-extruded gaskets ensures long-term protection and durability against water infiltration.

  • 02. EPDM GASKET CORNERS

    Vulcanized EPDM corner gaskets deliver maximum sealing performance at every edge, maintaining airtight and watertight protection — even under extreme weather conditions.

  • 03. EPDM END CAPS FOR ADJOINING PROFILES

    Special EPDM end caps with smart locking clips provide superior waterproof integrity and consistent sealing, even across double-sash configurations.

DURABILITY FOR A LIFE TIME

 

 

It’s the details like this that meet the highest standards of durability.
As time puts this profile to the test, you’ll appreciate its lasting strength and long-term performance.

  • SUPPORT FOR GLAZING LOAD TRANSFER

    This support system redirects the glass weight toward the inner section of the window sash, where all functional hardware components are located. By doing so, it ensures long-term stability, smooth operation, and lasting performance — regardless of the glass size or weight.
