Fixed window INSIO®

casementglassdouble-glazed

PRODUCT DESCRIPTION
In a collaboration between Saint-Gobain Glass and LuxWall, INSIO® integrates LuxWall’s transparent vacuum insulation technology to deliver next-generation vacuum insulating glazing. INSIO® features a sub-0.3 mm vacuum gap between two glass panes, reducing heat transfer and airborne noise compared with conventional double or triple glazing. The tempered safety glass construction permits a low micro-pillar density and reduced need for internal supports, enabling slim profiles and low Ug-values when combined with low-emissivity coatings. CLIMAPLUS® INSIO® embeds INSIO® into a conventional insulating glass unit (IGU) with a standard spacer and counter-glass, providing standard IGU thickness for easy installation in existing window systems.

BENEFITS & APPLICATIONS
Saint-Gobain Glass and LuxWall commercialize INSIO® to tackle weight, thickness and carbon footprint constraints of high-performance glazing. Typical applications include retrofit and historic restoration where slim profiles are required, as well as new construction and renovation using CLIMAPLUS® INSIO® in standard frames.

• INSIO® 10 mm (standard; also available in 8 mm and 12 mm on request) is adapted for replacing older glazing while keeping existing frames.
• CLIMAPLUS® INSIO® achieves standard IGU thicknesses (≈24 mm depending on spacer and counter-glass) for compatibility with current window systems.

Main benefits

• Outstanding thermal insulation — Ug values between 0.5 and 0.3 W/m²K depending on configuration and counter-glass.
• Slim profile — significantly thinner and lighter than traditional triple glazing, suitable for retrofit and heritage frames.
• Easiness of integration — INSIO® can be used within double-glazing systems; CLIMAPLUS® INSIO® fits standard frames.
• Superior acoustic performance — INSIO® 10 mm certified acoustic value: 35(-2;-2) dB.
• Durability — long-term performance with a manufacturer limited warranty of 20 years.
• Energy efficiency — reduces heating and cooling loads, lowering building energy consumption.

APPEARANCE
INSIO® and CLIMAPLUS® INSIO® are transparent solutions designed for window glazing. Tempered glass enables a low micro-pillar density (≈50 mm grid), optimising aesthetics and thermal performance.

TECHNICAL INFORMATION
Standard INSIO® version: INSIO® 10-C1 (10 mm) with integrated low-emissivity layer. Optional solar-control variants: INSIO® 10-C2 and 10-C3 (reduce g and Ug while lowering visible transmittance). Standard sizes: from 305 x 457 mm up to 1 524 x 2 438 mm. CLIMAPLUS® INSIO® integrates INSIO® as one lite in a standard IGU with a spacer and counter-glass; typical CLIMAPLUS® INSIO® thickness ≈24 mm (depending on spacer/counter-glass). INSIO® is CE marked and has followed the EOTA route for Vacuum Insulating Glass Units (EAD 300021-00-0404 / ETA 25/0363). Availability: Europe.

PERFORMANCE
Measured thermal and acoustic data are available for INSIO®; calculated data illustrate expected CLIMAPLUS® INSIO® configurations (INSIO® 10-C1 and solar-control variants 10-C2/10-C3) with different counter-glass choices.

TOOLS & SERVICE
Associated tools and services include GlassPro and Calumen® for architectural visualisation and thermal calculations.
