Improving Production Efficiency with RapidFit Premium Frame Systems

How CoreLux A1 Cladding Helped Solve Three Critical Modular Construction Challenges

As modular construction continues to evolve, manufacturers face increasing pressure to deliver buildings that not only meet demanding performance standards but also exceed expectations for design, sustainability and speed of delivery.

For one modular manufacturer, the challenge was clear.

They needed a façade solution that would deliver a premium architectural appearance, support modern fire safety requirements and integrate seamlessly into a fast-paced factory production environment.

The answer was CoreLux A1 Cladding.

The Challenge

Modern modular construction is built around efficiency, repeatability and quality.

However, achieving these goals becomes more challenging when balancing competing project demands.

The manufacturer required a cladding solution that could:

• Meet stringent fire safety requirements
• Deliver a premium architectural finish
• Support factory-controlled installation processes
• Reduce programme time on site
• Minimise ongoing maintenance requirements
• Provide long-term durability and weather resistance
• Create a façade suitable for modern residential and commercial developments

Traditional façade materials often required compromises between appearance, performance and installation efficiency.

The project team wanted a solution that could deliver all three.

The Eltherington Approach

With more than 65 years of experience supporting the modular construction sector, Eltherington understands that successful products must perform just as effectively on a production line as they do on a finished building.

CoreLux A1 Cladding was developed specifically to address these challenges.

Combining premium architectural aesthetics with modern installation methodology, the system enables manufacturers to achieve high-quality building envelopes without compromising speed, safety or performance.

The system was selected because it offered:

• A1 non-combustible fire performance
• FastFix installation technology
• Secret-fix architectural appearance
• Premium timber-effect finishes
• Long-term weather resistance
• Low maintenance ownership benefits
• Compatibility with modern modular construction methods

Designed for Modern Modular Manufacturing

Unlike many traditional façade systems, CoreLux A1 Cladding has been engineered with installation efficiency at its core.

The FastFix system simplifies the installation process through:

• Quick-Rail support systems
• Pre-engineered fixing methods
• Dry-fit installation
• Hidden fixing technology
• Reduced installation stages
• Minimal requirement for specialist site works

For modular manufacturers, this translates into improved production efficiency, greater installation consistency and enhanced programme certainty.

The result is a façade system that supports both factory production and on-site project delivery.

Premium Architecture Without the Maintenance Burden

One of the key project objectives was to achieve a contemporary architectural appearance that would enhance the perceived value of the completed building.

CoreLux A1 Cladding delivers the warmth and character of natural timber through embossed aluminium finishes that replicate the texture and depth of real wood.

Available in finishes including Cedar, Acadia, Almond, Timberwolf and Cliffside, the system provides architects and developers with the flexibility to create distinctive building identities while benefiting from the durability of aluminium.

Unlike traditional timber-based alternatives, CoreLux requires no painting, staining or ongoing treatment, significantly reducing long-term maintenance costs.

Fire Performance Built In

Fire safety remains one of the most important considerations in modern modular construction.

CoreLux A1 Cladding is manufactured from non-combustible aluminium and achieves an A1 fire classification, providing confidence for manufacturers, developers and building owners alike.

Rather than being treated as an upgrade or additional specification, fire performance is embedded within the system from the outset.

This allows project teams to focus on design and delivery while maintaining confidence in building envelope performance.

Supporting Long-Term Building Performance

Modular buildings are increasingly expected to deliver decades of reliable service.

CoreLux A1 Cladding has been developed to provide:

• Exceptional weather resistance
• UV protection and colour stability
• Long-term durability
• Resistance to impact and environmental exposure
• Minimal maintenance requirements
• Sustainable lifecycle performance

By combining these benefits within a lightweight aluminium system, the product helps support long-term asset value and reduced ownership costs.
