Removing Bottlenecks from the Production Line

How RapidFit Premium Frame Helped a Modular Manufacturer Increase Throughput Without Compromising Quality

Modern modular construction is built on one principle: repeatability.

Every process, every component and every installation method must work consistently, day after day, module after module.

When a leading modular manufacturer approached Eltherington, they weren’t looking for another window system.

They were looking for a way to remove inefficiencies from their production line.

As demand increased across residential, education and healthcare projects, glazing installation was becoming a critical area of focus. Multiple installation stages, varying wall constructions and inconsistent finishing processes were creating unnecessary complexity within production.

The challenge was clear.

Find a glazing solution that could improve factory efficiency, reduce installation time and maintain a premium finish across every building leaving the factory.

That solution was RapidFit Premium Frame Systems.

The Challenge

For modular manufacturers, time lost on the production line cannot be recovered.

Every additional installation stage, adjustment or finishing process impacts throughput, labour efficiency and programme certainty.

The customer needed a glazing system capable of:

• Reducing installation complexity
• Improving production-line flow
• Supporting multiple wall constructions
• Delivering consistent quality
• Simplifying internal finishing
• Increasing factory throughput
• Maintaining thermal and structural performance

Traditional glazing systems often required multiple trades, additional finishing work and increased handling during installation.

The manufacturer wanted a system engineered specifically around modular production principles.

The Eltherington Approach

With more than 65 years of experience supporting offsite construction, Eltherington understands that successful products must work for manufacturers first.

RapidFit Premium Frame Systems were developed specifically for modern modular production environments, combining glazing, fixing and finishing details into a single factory-ready package.

The solution included:

• Pre-glazed energy-efficient units
• Precision-engineered odd-leg sealing faces
• Integrated internal architrave liner kits
• Cornerless internal finishing system
• Concealed steel reinforcement
• Through-frame fixing options
• Custom stillage delivery

The objective wasn’t simply to install windows faster.

It was to create a glazing solution that removed friction from the manufacturing process.

Built Around Production Efficiency

Unlike traditional glazing systems adapted from mainstream construction, RapidFit Premium Frame was designed specifically for repeatable factory installation.

Every component was engineered to reduce handling, simplify fitting and improve consistency.

By supplying the system pre-glazed and installation-ready, the manufacturer was able to reduce labour requirements while improving installation speed.

Integrated architrave liners eliminated additional finishing operations, while repeatable fixing methods improved consistency across production runs.

The result was a glazing solution that worked with the production line rather than slowing it down.

One System. Multiple Building Types.

Flexibility remained critical.

The manufacturer produced a diverse range of modular buildings, each with different wall constructions and specification requirements.

RapidFit Premium Frame accommodated wall thicknesses from 81mm to 170mm as standard, with through-frame fixing options providing additional flexibility where required.

This allowed a single glazing platform to be used across:

• Modular housing
• Student accommodation
• Healthcare facilities
• Education buildings
• Commercial projects
• Portable and temporary buildings

The result was greater standardisation without sacrificing design flexibility.

Better Finishes. Less Work.

One of the standout features of RapidFit Premium Frame is its innovative cornerless internal architrave system.

Rather than relying on additional finishing works after installation, the system incorporates clean, integrated internal detailing as part of the glazing package.

For the manufacturer, this delivered:

• Reduced finishing time
• Improved presentation
• Greater installation consistency
• Higher perceived quality

A better result for both production teams and building occupants.

The Result

Following implementation of RapidFit Premium Frame Systems, the manufacturer achieved:

Increased Production Efficiency

Fewer installation stages and reduced handling improved factory throughput.

Improved Installation Consistency

Repeatable fixing methods delivered consistent results across every module.

Reduced Production Complexity

A complete pre-glazed system simplified installation and finishing.

Greater Specification Flexibility

One glazing platform capable of supporting multiple building types.

Enhanced Internal Finishes

Integrated architrave solutions improved quality while reducing labour.

Long-Term Building Performance

Durable materials, robust reinforcement and energy-efficient glazing delivered lasting value.

Building Smarter for the Future

As modular construction continues to scale, manufacturers need products that do more than perform well after installation.

They need systems that actively improve the way buildings are produced.

RapidFit Premium Frame Systems were developed with exactly that objective in mind.

By combining pre-glazed installation, innovative fixing methods, integrated finishing details and production-line compatibility, the system helps modular manufacturers increase efficiency, improve consistency and deliver better buildings at scale.
