Effective insulated sandwich panels require a robust, reliable and quality core material. Partnering with ROCKWOOL Core Solutions ¹ offers exactly that.

However, our specialists also become an extension of customers’ operations, working with (OEMs) and sandwich panel manufacturers to innovate stone wool insulation solutions. This in turn provides enhanced fire protection, acoustic performance, thermal regulation and mechanical performance for constructions.

We consult directly with you, creating solutions that work best for your manufacturing process, whether that be lamellas or slabs. We also support sandwich panel manufacturers through the certification and testing phases.

In addition, our experts can share knowledge that will help you use our products to their maximum effectiveness.

Our insulation can be customised for projects of any size, application and building requirements.

Sandwich panels

Why do we need insulated sandwich panels?

Engineers, contractors, architects and building owners are under more pressure than ever to construct buildings that are energy efficient, safe and sustainable.

This, alongside an emphasis on speed of construction, can prove a significant challenge.

Sandwich panels which integrate our stone wool core material can play their part in improving insulation in the most important areas.

They’re suitable for insulating ceilings, interior and exterior walls (including partition walls and facades) and roofs – as well as for firewall applications. When installed, stone wool insulation harnesses the 7 Strengths of Stone², offering:

Increased fire protection – stone wool core insulation integrates non-combustible properties to sandwich panels, delivering the highest European fire classification A2-s1, D0³.
Acoustic capabilities – blocking unwanted noise from attached or neighbouring buildings⁴.
Thermal performance – temperatures are better regulated in buildings, thanks to the smart fibre structure of stone wool insulation⁵.
Bespoke solution – products are manufactured in advanced plants, ensuring a customised product for your sandwich panel process⁶.

Calculator and savings

We work closely with sandwich panel manufacturers throughout the product innovation process: from the initial preparation and testing stages, to the creation of the solutions themselves.

We also share our knowledge and expertise to help our partners understand the importance of stone wool insulation performance, and how it can bring value and savings to sandwich panel building projects.

Our direct work with sandwich panel manufacturers goes beyond mere supply. First, we provide stone wool insulation for the core of sandwich panels. Then, we provide services such as certification support, fire tests, packaging, innovation of new products, and can advise on boosting production line efficiencies too.

Once sandwich panels with a stone wool core have been installed, buildings and complexes can enjoy increased energy efficiency, thanks to improved thermal regulation.

By raising the energy efficiency with stone wool insulation, savings are then passed on to the building owner or operator.

Use our ROCKWOOL U-value calculator to determine the thermal performance of the building’s walls and possible cost savings. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

Why choose ROCKWOOL Core Solutions?

We supply high-quality stone wool insulation solutions that can increase fire protection, acoustic performance and thermal regulation.

In addition, our stone wool solutions are part of the overall customised, partnership service we can offer OEMs. This is something we call The Power of & - an approach that emphasises how we add to your offering.

The services we provide in the course of our partnership play a major part in this.

Consultative – we work closely with sandwich panel manufacturers to understand their manufacturing processes and systems. During the preparation phase, our stone wool specialist will consult with you directly, sharing best practice tips and calculating the correct amount of stone wool needed for a project.
Knowledgeable – these solutions will then be tested and trialled, according to the latest standards and regulations. Our stone wool expert will attend and share local specialist product knowledge throughout.
Best practice – once the installation stage arrives, we provide expert advice on how best to conserve the integrity of the stone wool core, both when it’s stored on-site and when it is ultimately installed.
Bespoke – we take what we’ve learned about a particular project and your systems, then optimise our stone wool core insulation solutions to create a bespoke product tailored for your needs.

All our solutions are manufactured using specialised equipment. This improves the overall quality of an installation and has been tested to ensure it’s the optimal choice for the application intended – assuring you of its quality when installed⁷.

Installation

Stone wool cores are integrated into sandwich panels via an offsite manufacturing process, conducted by the external sandwich panel manufacturers we work with.

This makes installation easier and quicker – speeding up the construction process.

Key tips:

We will work alongside sandwich panel manufacturers to determine the safest and most efficient way to integrate stone wool core solutions.
Choosing to manufacture sandwich panels off-site can significantly improve your safety record⁸.

Inspiration and guides for professionals

Discover how The Power of & can work for you as an OEM!

At the ROCKWOOL Group, we ensure that all your products and systems will benefit from The Power of &. That’s because when you design one strength into a product with stone wool, you gain all the 7 Strengths of Stone. With ROCKWOOL Core Solutions as your partner, you also gain ‘&’ in many other ways, through qualities that set our organisation apart.

Sustainability and energy efficiency

Our solutions can help sandwich panel manufacturers develop products and building elements that are fit for purpose, sustainable and environmentally friendly.

In the materials sector, resource efficiency is important, particularly when climate neutrality goals have been set – such as the Paris Agreement⁹.
