The Janisol HI system represents a breakthrough in thermal steel fenestration, earning distinction as the first steel window system to receive Minergie certification. This premium system combines sophisticated aesthetics with cutting-edge thermal technology, delivering exceptional performance through slim profile designs.
The Janisol HI window system redefines thermal performance in steel fenestration, achieving exceptional insulation while preserving the timeless aesthetic and structural integrity of steel profiles. This groundbreaking system is the first steel window to receive prestigious Passivhaus certification for its fixed glazing units—setting a new industry benchmark for thermal efficiency.
Engineered to meet the multifaceted demands of modern architecture, Janisol HI windows deliver remarkable thermal transmittance values as low as 0.69 W/m²K for fixed glazing and 0.8 W/m²K for operable windows. The system’s advanced insulating technology features glass fiber-reinforced polyurethane bars that dramatically reduce thermal bridging while maintaining the slender profiles that distinguish steel from other materials.
With a substantial basic depth of 3 9⁄16″ (90mm), the system accommodates infill unit thicknesses up to 2 5⁄8″ (67mm), providing exceptional design flexibility. The robust engineering supports impressive dimensional capabilities with heights up to 9′ 2 1⁄8″ (2800mm) and casement weights up to 397 lbs (180kg), ensuring durability in even the most demanding applications.
Available in multiple configurations, these windows offer dimensional versatility with heights up to 9′ 2 1⁄8″ (2800mm) and widths ranging from 1′ 11 5⁄8″ (600mm) to 9′ 2 1⁄8″ (2800mm) depending on the selected style. The system maintains aesthetic proportions with a Window sash width / Window sash height ratio guideline of ≤ 2, ensuring visual harmony while maximizing performance.
The slimline external face width preserves the characteristic elegance of steel profiles while delivering superior thermal performance. Combined with an extensive range of coating options, Janisol HI windows provide architects complete freedom to meet the highest thermal requirements without compromising on design vision.
Our highly insulated Janisol HI steel doors deliver exceptional thermal performance while maintaining superior structural integrity—ideal for demanding public buildings. With impressive thermal transmittance values as low as 1.0 W/m²K, these doors offer industry-leading energy efficiency without compromising on strength or security.
The system features a robust 3 1⁄8″ (80mm) basic depth that accommodates infill units up to 2 1⁄4″ (57mm) thick. Door configurations offer remarkable versatility with single door clear openings of 1′ 11 5⁄8″ to 4′ 5 1⁄2″ (600-1360mm) width and 6′ 2 3⁄4″ to 9′ 9 3⁄4″ (1900-2992mm) height, while double doors expand to 3′ 11 1⁄4″ to 8′ 11 7⁄8″ (1200-2740mm) width. Both configurations support substantial leaf weights up to 617 lbs (280kg), ensuring durability in high-traffic environments.
Our comprehensive range of coordinated fittings, accessories, and application-specific thresholds provides complete design flexibility. The innovative insulating bar design, made from glass fiber-reinforced polyurethane, allows for efficient central lock installation while maximizing thermal performance.
The Janisol HI door system conveniently combines mechanical stability with high thermal insulation properties, meeting the dramatically increased requirements for security, durability, and energy efficiency in busy public buildings.
