UNITIZED CURTAIN WALL

UNITIZED CURTAIN WALL

 

POLMEK Unitized Curtain Wall Systems are produced in the factory together with glass and all components, undergo quality control, and are shipped ready for direct installation on site without requiring assembly.

They offer an ideal façade solution for medium and high-rise buildings; while reducing installation time, they ensure high performance and aesthetic integrity.

The system supports different glass and insulation options; it meets structural, acoustic, thermal, and air/water tightness requirements and allows for standard or project-specific cladding solutions.
 


What we do? 

• Prefabricated Unitized Curtain Wall manufacturing
• Fast modular on-site installation
• Worldwide turnkey Facade installation services
• Solutions for high-rise and complex façade geometries
• Structural, thermal, air and water performance tests
 

 

Materials and Profile Systems

  • Aluminum alloy profiles provide high durability and corrosion resistance.
  • Profile surfaces are anodized or powder-coated, offering a wide range of RAL color options.
  • EPDM or silicone-based gaskets are used in glass support systems.

Glass Types

  • Double or triple glazed units (thermal insulated, low-emissivity (Low-E), tempered, laminated, and sound-insulated glass).
  • Solar control glasses with reflective or colored options are available.
  • Glass thickness and cavity distances are optimized according to the project.

Thermal Insulation

  • Heat loss is minimized thanks to thermal aluminum profiles.
  • Different profile and glass combinations can be applied for varying levels of thermal insulation.

Water and Air Tightness

  • Multi-gasket systems ensure air permeability class according to EN 12207.
  • Water tightness testing complies with EN 12208 standard, guaranteeing water tightness under high pressure.

Structural Strength

  • Wind load resistance is tested according to EN 13116 and relevant local standards.
  • Profiles and connection elements are dimensioned based on static calculations according to the project to ensure safety.

Acoustic Performance

  • Acoustic performance is optimized with glass combinations and profile design.
  • Special acoustic solutions can be applied in projects requiring high sound insulation.

Installation and Transportation

  • Unitized panels are delivered fully integrated and completed in the factory (including glass and accessories).
  • Mechanical connections are made on-site, thus reducing installation time and labor costs.
  • Thanks to its modular structure, damage risk is minimized and quality control is easier.

Additional Features and Accessories

  • Integration with systems is possible for unitized panels.
  • Various decorative cladding alternatives are available.
  • Integrated sensor and motor systems can be applied for smart facade solutions.

• Standardization of elements at the stage of design.
• High assembly quality, precise control of manufacturing process, final quality inspection.
• On-site mounting with fewer work operations, which significantly reduces the «human factor» effect (faulty goods).
• Period of construction doesn’t depend on weather conditions, as the products are manufactured in the workshop.
• A floor-by-floor installation method is used, therefore, due to concealed thermal insulation jig finishing works can be carried out at the earlier stage.
• Internal visible profile width (In addition to standard sizes, profile options suitable for the project are available..)
• External visible profile width  (In addition to standard sizes, profile options suitable for the project are available.)
• Max. infill unit thickness   (In addition to standard sizes, profile options suitable for the project are available.)
• Max. module heigh 
• Max. sash width 
• Thermal insulation EN ISO 10077-2:2017 
 

Unitized curtain wall panels are produced under factory conditions to ensure consistent quality and precise detailing before installation on site.
Pre-assembled units allow quick installation, reducing on-site work time and minimizing construction risks.
The system provides a clean and continuous façade look with aligned joints and consistent panel geometry.
Unitized systems can be applied to various building forms and project requirements without limiting architectural design.
Designed to perform reliably against wind, rain, and temperature changes in different climate conditions.

We provide turnkey solutions for unitized curtain wall projects, offering comprehensive services from unitized curtain wall production to meticulous detailing and professional unitized curtain wall installation.

Our expertise includes high-performance unitized glass curtain walls and durable aluminum unitized curtain wall systems, delivering modern glass and aluminum solutions that enhance both aesthetics and functionality. Each unitized facade is carefully designed using pre-fabricated unitized curtain wall components and precisely crafted unitized curtain wall panels, ensuring consistent quality and superior unitized curtain wall performance.

Pre-fabricated curtain wall options enable faster installation, reducing labor requirements and optimizing project timelines. We provide detailed curtain wall system comparisons to help clients select the most suitable solution for their needs.

Our aluminum-framed glass curtain wall systems, integrated with advanced unitized glass curtain wall panels and unitized glass panel technology, offer both safety and elegance. Every project benefits from professional unitized curtain wall installation, executed with precision to meet the highest standards of durability, performance, and design excellence.

UNITIZED CURTAIN WALL TECHNICAL Q&A

What is a unitized curtain wall? A curtain wall system manufactured in the factory with the glass and all components integrated, and quickly installed on site as modular panels.
Unitized vs. Stick System? The unitized system provides fast and controlled installation with factory-completed panels, while the stick system is assembled piece by piece on site and requires a longer installation period.
How does it compare with structural glazing? Structural glazing offers glass continuity and transparency, whereas the unitized curtain wall provides modular production advantages and high sealing performance.
How does it compare with a ventilated facade? A ventilated facade controls moisture and heat with a rear ventilation cavity, while the unitized curtain wall delivers high facade performance through integrated insulation and sealing layers.
Which tests are applied? Water, air, wind, and structural performance tests are conducted to ensure system integrity.
How is the energy performance? The U-value is reduced through thermal insulation and high-performance glazing, ensuring superior energy efficiency.
Unitized vs. Double Skin Facade? A double skin facade increases acoustic and energy performance with its two-layer structure, while unitized provides high performance in a single layer with faster installation.
Unitized vs. Aluminium Facade Systems? Aluminium facade is a general cladding definition, whereas the unitized curtain wall is a specialized solution where aluminium framing and glass form a modular panel.
Best projects for Unitized Systems? It offers clear superiority in high-rise buildings, large facade areas, and projects requiring fast construction schedules.
How is quality control ensured? Since production is carried out in a factory environment, dimensional accuracy, sealing, and installation quality are verified in advance.
Why preferred in Turnkey Projects? It reduces project duration and risks thanks to fast installation, high performance, low on-site labor, and centralized production control.
