High-Rise Ventilation Excellence Meets Architectural Integrity.
Aluminum Parallel Opening Windows
LIKI Parallel Opening Systems redefine architectural ventilation by providing a uniform, 360° airflow path that preserves the clean lines of modern high-rise facades. Designed for maximum High-Rise Safety and aesthetic consistency, this system offers a revolutionary solution for projects where traditional swinging windows are not an option.
Explore Our Precision Parallel Opening Window Systems
LIKI provides a specialized portfolio of Parallel Opening Window platforms designed to solve high-rise ventilation challenges. Every system is engineered with thermally broken profiles and high-precision GU (Gretsch-Unitas) hinges as standard. For our oversized 118-inch sashes, we integrate heavy-duty Securistyle (UK) hardware to ensure balanced load transfer and superior Air-tightness under extreme AAMA/ASTM testing conditions.
73 Series: Concealed-Frame Parallel Opening Window System
Engineer high-rise safe ventilation through a parallel-opening system that shifts the sash off the seal plane and holds it planar to the façade for controlled, uniform airflow.
- ●System Adaptability: Maintain a stable 2.87-inch core frame depth while supporting hidden-frame detailing, continuous façade modules, and manual or motorized operation—without fragmenting into new SKUs.
- ●Load-Controlled Hardware: Control the opening sequence through parallel hardware—disengage, translate, and hold—so sash forces remain balanced during operation for large-format and high-rise window positions.
- ●Performance Matched: Evaluated to EN 12207 / 12208 / 12210 and ASTM E283 / E330 / E331, supporting insulating glass up to 0.94 inches and maximum panel heights up to 118 inches (configuration dependent).
98PW Series: Thermally Broken Parallel Opening Window System
Engineer-controlled façade ventilation through a thermally broken parallel-opening system that maintains full perimeter compression sealing when closed and uniform airflow when opened.
- ●System Adaptability: Utilize a stable 3.86-inch structural frame platform designed for high-rise and continuous window-band façades where outward or inward casement operation is not suitable.
- ●Load-Controlled Hardware: Apply dedicated parallel-opening hardware to disengage, translate, and hold the sash in a controlled sequence, ensuring balanced load transfer and smooth operation in manual or motorized configurations.
- ●Performance Matched: Evaluated to EN 12207 / 12208 / 12210 and ASTM E283 / E330 / E331, stabilized by Technoform® Thermal Breaks, wet-sealed glazing using Wacker®, and a multi-layer EPDM sealing system.
130ZKW Series: Flagship Thermal Parallel Opening Window System
Engineer energy-efficient façade ventilation through a slim-frame parallel-opening system developed on LIKI’s flagship 130 platform, balancing user-friendly operation, airtight performance, and consistent architectural proportions.
- ●
System Adaptability: Utilize an approx. 5.12-inch system frame depth with a multi-chamber load-bearing structure suitable for mid- and high-rise applications, while maintaining slim, flat-aligned façade proportions across varied configurations. - ●
Load-Controlled Hardware: Apply dedicated parallel-opening hardware to guide the sash through a controlled translate-and-outward movement, with all load paths confined within structural chambers and isolated from the thermal break and glazing system. - ●
Performance Matched: Evaluated to EN 12207 / 12208 / 12210 and ASTM E283 / E330 / E331, supported by Technoform® Thermal Breaks, wet-sealed glazing using Wacker®, and a multi-layer EPDM sealing system within NFRC-certified configuration scopes.

Parallel Opening Window Systems FAQs answered
It’s all about control. Traditional windows can be unpredictable in high winds. Our parallel systems stay perfectly aligned with the wall, providing Safe Ventilation without the risk of the wind catching a swinging sash.
Yes, during light rain. Because the sash shifts out evenly on all four sides, it creates a protected perimeter gap. Combined with our Pressure-Balanced drainage, it manages water much better than a standard slider or awning window.
Absolutely. We offer Motorized Parallel Opening configurations. This is ideal for high-transom windows in office towers or luxury lobbies where you want automated, Smart Building air exchange.
Even better. Unlike sliding windows that rely on brushes, LIKI parallel windows use a Multi-layer EPDM compression seal. When you close the window, our precision GU (Gretsch-Unitas) hinges—or high-capacity Securistyle hardware for oversized sashes—pull the sash firmly against the frame, achieving elite Airtightness.
We use precision-balanced hardware designed for sashes up to 118 inches tall. By distributing the weight evenly across multiple points, we ensure smooth operation and prevent sagging, even with heavy triple-pane glass.
Absolutely. LIKI uses a tiered hardware strategy: precision GU (Gretsch-Unitas) hinges for standard residential use and world-renowned Securistyle (UK) parallel stays for our oversized high-load sashes. This combination prevents sagging and ensures a smooth, dual-motion operation for decades.
That’s exactly why we use Technoform® thermal breaks and high-compression seals. Our systems are engineered to handle the pressure differences in tall buildings, maintaining a stable Thermal Boundary and keeping your energy bills low.
