Prefabricated insulated building elements need to be resilient, robust and add real value to the finished construction.

Our custom stone wool core insulation solutions are easily integrated into your manufacturing process, providing OEM offsite construction with seamless, high-quality results.

But partnering with ROCKWOOL Core Solutions offers more than just bespoke insulation – whether you are producing 2D insulated elements or 3D modular systems. Everything we do follows our philosophy and approach, which we call The Power of &.

Learn how ROCKWOOL Core Solutions can help you create sustainable, effective and energy-efficient solutions for your prefabricated building manufacture.

Why do you need insulation for prefabricated building elements?

Modular and prefabricated buildings need to be just as energy efficient, fire resilient and noise resistant as other types of construction.

It can be far easier, however, to introduce fire protection, acoustic absorption and thermal regulation properties to prefabricated building elements pre-construction, ultimately improving the structure as a whole.

A partnership with ROCKWOOL Core Solutions can enhance the individual parts of prefabricated buildings offsite – before they are assembled. We work with you to create the best prefabricated elements possible, such as insulated precast concrete walls.

Integrating quality insulation at this stage avoids extra time, work and materials needed at a later stage, ensuring prefabricated buildings meet the needs of their occupants right away.

Our core stone wool insulation is:[1]

Customisable to your process needs, and according to the performance, dimension and/or mechanical strengths required for the building element
Highly durable
Highly sustainable and recyclable
Able to maintain the same compression strength without compromising thermal and mechanical performance

Design with More Energy Efficiency

The amount of stone wool core insulation required will depend on the size and shape of the prefabricated building elements you manufacture.

As well as customising stone wool for physical feasibility, we can also manipulate the fibre orientation to deliver various performance enhancements and mechanical strengths.[1]

Our customised stone wool design capabilities can provide solutions that integrate into products of varying dimensions and performance focuses.

Specialists will support your operations along the way, from purchase order to quality satisfaction, to save time and reduce waste.

Stone wool enhances the thermal regulation of structures. By improving the energy efficiency of construction components for prefabricated buildings, you can pass on these energy savings to occupants.

Why choose ROCKWOOL Core Solutions?

We provide core insulation solutions directly to OEM offsite construction, tailored to your needs for:

2D insulated elements – flat structures assembled into a modular construction.
3D or Modular Systems – full structures with walls, floors and ceilings that can be built from 2D systems.

Offering a unique consultative approach, we support you through our stone wool specialists – from product ordering to implementation – to ensure a seamless process that creates a high-quality end product. Our local experts collaborate to understand your products, production facilities and market needs to deliver bespoke insulation that suits your requirements.

We work alongside OEMs to:

Help you meet strict timelines
Optimise your process through just-in-time delivery and correct material volumes
Provide quality assurance during testing, regulation and certification stages
Offer customer service and supply chain communication throughout
Provide you with a bespoke and successful solution that addresses challenges around cost, design and warranties. This can help your 2D and 3D modular constructions work towards achieving BOPA accreditation.

ROCKWOOL core insulation also harnesses the 7 Strengths of Stone, providing benefits including:

Improved fire safety – A1 classified non-combustible insulation.[1] Our stone wool does not emit toxic smoke and is designed to slow the spread of flames.
Sustainability – our solutions are circular, boost energy efficiency, are backed by environmental product declarations (EPDs), and can help prefabricated buildings conform to sustainable building schemes.
Thermal properties – provides effective protection against both cold and heat.[2]
Acoustic performance – sound absorption helps to controls echo, while sound insulation stops noises travelling to other rooms.[3]

Our high-quality stone wool can improve the durability, fire resilience and acoustic absorption of prefabricated elements. It retains its dimensional stability and thickness with no shrinkage or sagging over time, ensuring the strong thermal and mechanical performance of your elements.

Custom core insulation is designed to effortlessly fit in with your manufacturing process, for easy integration. Thickness tolerances can reach +/- 0.5mm to ensure an accurate cut for your prefabricated building elements.

Testing

Once we have produced your tailored solution, we thoroughly test it on site so we can be sure it delivers maximum performance when integrated into your prefabricated building elements or systems. All solutions are rigorously tested and backed by Environmental Product Declarations (EPDs)[4].

We can also support you with any third-party standardisation tests. This includes attending such test sessions, talking you through the results and what they mean for your products.

Sustainability and energy efficiency

Stone wool can also be recycled again and again, without impacting its quality or performance8. This means you can remove it from a construction at the end of its life to reuse – boosting the circularity of the manufacturing and construction industries9.

Because we offer customised solutions, this further reduces waste during the integration of insulation – helping you hit any environmental targets you may have.
