UNITIZED CURTAIN WALL

POLMEK Curtain curtain wall systems are produced in the factory together with glass and all components. These panels are shipped to the construction site as finished products after undergoing strict quality controls and are brought to the construction site ready for direct installation without assembly labor.

It is the perfect façade solution for medium and high-rise buildings. While the installation time is significantly shortened, the precision provided during the production process results in high performance and aesthetically superior facade systems.

The system can be applied with different glass types and thermal insulation levels. It is designed to meet all technical requirements such as structural, acoustic, thermal and air/water impermeability. The unitized curtain wall system allows standard or project-specific cladding configurations thanks to its modular structure. The system can be enriched with different integrated options. In this way, it offers flexible solutions to different architectural expectations in terms of both aesthetics and performance. All components are integrated in the factory environment, shipped with high quality standards and applied on site with minimum assembly time.

 

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 
 

Panels are mass-produced at the factory, so the components are precisely installation and easy to control the quality.
Unitized Panel is small, flexible, convenient, easy to install, maintain and replace with simple operation, short construction time and high construction efficiency.
The method of sealing the structure between Unitized Panel and traditional glue is replaced by the strip of sealant, ensuring sealing and reducing the level of pollution on the surface of curtain wall, bringing aesthetics, enhancement decorative effect.
With 3 layers sealed inside curtain wall, high waterproofing purpose. The drainage system is perfectly designed. Ability to withstand the rigors of weather.
Ensuring safety, certainty, especially for high-rise buildings. The firing of structural glue is carried out at the factory, so the quality control is guaranteed.
