Effective insulated sandwich panels require a robust, reliable and quality core material. Partnering with ROCKWOOL Core Solutions1 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.

Discover how ROCKWOOL Core Solutions can improve your sandwich panel performance, resilience and sustainability today.

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.

FAQs

What is a sandwich panel?

A sandwich panel is a building element that consists of two external metal sheets, reinforced with a core insulation material in the middle. The use of stone wool core insulation delivers the highest fire classification a sandwich panel can achieve: A2-s1, D0.
