Improving Production Efficiency with RapidFit Premium Frame Systems

How RapidFit Premium Frame Helped Streamline Modular Manufacturing

In modern modular construction, efficiency isn’t just measured by what happens on site. It starts on the production line.

As modular manufacturers face increasing pressure to reduce build times, improve consistency and deliver high-quality buildings at scale, every component within the building envelope must contribute to a smoother, more efficient manufacturing process.

When a modular manufacturer approached Eltherington, they were looking for a glazing solution that could simplify installation, improve repeatability and integrate seamlessly into their factory environment.

The solution was RapidFit Premium Frame Systems.

The Challenge

The customer was experiencing growing demand across multiple modular building sectors, including education, healthcare and temporary accommodation.

With production volumes increasing, they needed a glazing solution that would:

• Improve installation efficiency
• Reduce production-line handling
• Support repeatable manufacturing processes
• Minimise finishing work
• Accommodate varying wall constructions
• Deliver consistent quality across every module
• Maintain strong thermal and structural performance

Traditional glazing systems often required multiple installation stages and additional finishing works, creating inefficiencies within the production environment.

The manufacturer wanted a solution designed specifically around the realities of modular construction.

The Eltherington Approach

With over 65 years of experience supporting offsite construction, Eltherington understands that the best modular products are those that simplify manufacturing without compromising performance.

Working closely with the customer’s production team, RapidFit Premium Frame Systems were specified as the ideal solution.

The system combines:

• Pre-glazed window units
• Precision-engineered odd-leg sealing faces
• Internal architrave liner kits
• Through-frame fixing options
• Integrated steel reinforcement
• Factory-ready installation methodology

The result was a complete glazing package engineered to improve production efficiency while maintaining high levels of quality and performance.

Designed Around Factory Production

Unlike conventional glazing systems, RapidFit Premium Frame has been developed specifically for modular manufacturing environments.

Every element of the system has been engineered to reduce installation complexity and improve production-line consistency.

Key features included:

• Pre-glazed supply solution
• Factory-ready installation
• Integrated internal finishing details
• Repeatable fixing methods
• Custom stillage delivery
• Minimal on-line adjustments

By reducing installation stages and simplifying handling requirements, the customer was able to improve production flow and reduce bottlenecks within the manufacturing process.

One System. Multiple Wall Constructions.

A key project requirement was flexibility.

The manufacturer produced multiple building types with varying wall build-ups and structural requirements.

RapidFit Premium Frame accommodated wall thicknesses ranging from 81mm through to 170mm using standard fixing methods, while through-frame fixing options provided additional flexibility for specialist applications.

This allowed the customer to standardise glazing specifications across multiple product ranges while maintaining installation consistency.

Delivering a Better Internal Finish

Beyond manufacturing efficiency, the customer wanted to improve the quality of internal finishes throughout their buildings.

RapidFit Premium Frame incorporates an innovative cornerless internal architrave system designed to simplify installation while delivering a cleaner, more contemporary appearance.

Combined with integrated liner kits and precision manufacturing, the system helped create a high-quality finished appearance with reduced finishing requirements.

The result was a glazing solution that enhanced both manufacturing efficiency and end-user perception of quality.

Performance Built In

While production efficiency was a primary driver, building performance remained critical.

RapidFit Premium Frame delivered:

Enhanced Thermal Performance

High-performance glazing options designed to support modern energy efficiency requirements.

Structural Integrity

Integrated steel reinforcement provides additional strength and durability across demanding modular applications.

Long-Term Reliability

Durable materials and robust fixing methods designed for long service life and reduced maintenance.

Flexible Configuration Options

Including Tilt & Turn windows for projects requiring enhanced ventilation and operational flexibility.

The Outcome

By implementing RapidFit Premium Frame Systems, the manufacturer achieved:

• Improved Factory Installation Efficiency

Reduced handling and simplified fitment processes across the production line.

• Greater Production Consistency

Repeatable installation methods ensured high standardisation across all modules.

• Enhanced Internal Finishes

Cornerless architraves and liner kits provided clean, modern visual appeal.

• Wall Build-Up Flexibility

Seamlessly accommodated variations in wall thicknesses from 81mm to 170mm.

• Improved Manufacturing Throughput

Minimised on-line adjustments and eliminated secondary finishing delays.

• Long-Term Performance

Maintained high structural integrity and energy efficiency across all developments.

Most importantly, they implemented a glazing solution designed specifically around the needs of modern modular manufacturing.

Redefining What’s Possible in Modular Construction

At Eltherington, we believe glazing systems should do more than perform well after installation. They should improve the way modular buildings are manufactured.

RapidFit Premium Frame Systems reflect that philosophy, combining robust performance, efficient installation and production-line compatibility within a single integrated solution.

Developed specifically for modern offsite construction, RapidFit Premium Frame helps modular manufacturers build smarter, faster and more consistently.
