Curtain Wall Unitized System

TECHNAL’s curtain wall unitized systems bring together high-performance engineering, modular precision, and sustainable design. 

Each pre-assembled unit is built for:

• durability, 

• energy efficiency, 

• and architectural flexibility. 

Ideal for modern high-rise and large-scale developments. 

Built for the Middle East’s demanding climate, TECHNAL systems offer high-quality performance. 

These systems ensure fast installation and long-term reliability for every project.

What Is a Curtain Wall Unitized System?

A curtain wall unitized system is made up of large, pre-assembled modules. They are manufactured and glazed in a controlled factory setting, then installed on-site as complete units.

This modular approach allows for:

• faster installation, 

• consistent quality, 

• strict factory testing to ensure precision,

• excellent thermal and acoustic performance.

Most importantly, the unitized curtain wall system allows for custom design. With this system, architects and developers can match their design intent. 

As such, these systems are ideal for high-rise and time-sensitive projects.

Types of Curtain Wall Systems and Key Differences

There are two main types of curtain wall systems: stick-built and unitized. The question is, what’s the difference between stick and unitized curtain wall systems?

Here are the key distinctions:

• Stick-built systems are assembled piece by piece on-site, making them suitable for smaller or less complex buildings. They offer flexibility but require more installation time and labour. Explore TECHNAL’s extensive TENTALfacade  range to see the options available. 

• Unitized systems are pre-fabricated in large panels at the factory. They are then delivered and installed as complete units. This ensures higher precision, faster installation, and improved performance.

A semi-unitized system combines both methods. Panels are partially assembled in the factory. Final connections are made on-site. This offers a balance between cost, logistics, and performance.

Technical Components and Performance Specifications

A unitized curtain wall system includes key elements such as:

• modules, 

• mullions, 

• transoms, 

• anchors, 

• gaskets, 

• pressure plates, 

• glazing, 

• and sealants.

 Each component is engineered for thermal insulation, air and water tightness, and wind resistance. This ensures reliable performance and durability across a range of architectural designs.

Advantages and Disadvantages of Unitized Systems

Advantages:

• Factory-controlled quality and precision

• Faster installation with minimal on-site disruption

• Excellent thermal and acoustic performance

• Modular flexibility for complex façade designs

Disadvantages:

• Higher initial cost

• Transport and handling challenges for large panels

• Dependence on accurate factory production

TECHNAL mitigates these challenges through modular design, standardised transport, and strict factory QA testing.  We ensure efficiency and long-term reliability on every project.

Regional Performance and Durability of Unitized Systems

TECHNAL’s unitized curtain wall systems are engineered to perform under the Middle East and Gulf Region’s toughest conditions. This ranges from intense heat and UV exposure to sandstorms, humidity, and coastal corrosion. 

Advanced coatings and materials manage thermal expansion. They protect against wear, ensuring long-term strength and stability.

Routine maintenance is simple: regular cleaning, annual inspections, and timely replacement of seals or gaskets keep the façade performing efficiently for decades.

Sustainability and ESG Benefits

TECHNAL’s unitized curtain wall systems are designed with sustainability in mind. 

They use low-carbon, recycled aluminium and support a circular design approach. Manufactured with Hydro CIRCAL 75R, which contains at least 75% recycled end-of-life aluminium, these systems significantly reduce embodied carbon.

Their energy-efficient performance and low maintenance needs to deliver long-term savings, reinforcing ESG value for developers, architects, and investors focused on sustainable construction.

Curtain Wall Unitized System: Cost Considerations and Project Planning

The curtain wall unitized system price depends on several factors, including:

• module size, 

• glazing type, 

• finish, 

• design complexity, 

• transportation, 

• structural and installation requirements. 

Initial costs can be higher than stick systems. However, the efficiency, reduced labour, and shorter installation times often balance the investment.

Over its lifetime, a TECHNAL unitized façade delivers strong lifecycle value through energy savings, long-term durability, and minimal maintenance. This makes it a cost-effective choice for large-scale developments.
