Buildings account for 28% of global carbon emissions, 36% of which are in the EU¹.
LC Spanrock
Low Carbon (LC) stone wool for sandwich panel insulation core
In fact, around 75% of buildings in the EU are energy inefficient, and most of them will still be in use in 2050².
Succeeding on climate action requires succeeding on making the world’s buildings far more energy efficient than they are today. Constructing new and renovating existing buildings with improved energy efficiency requires using well-known building materials and practices.
Prefabricating carbon reduction
Offsite construction has the potential to reduce the building industry’s carbon footprint and support the net zero target in several ways.
- Reducing travel to and from site
- Limiting on-site waste
- Utilising energy-efficient manufacturing methods
Stone wool insulated sandwich panels
Improving the thermal performance of offsite structures further contributes to reducing carbon emissions, by reducing the amount of energy required to regulate building temperatures. Integrating insulation into system design is key for achieving this.
Forging industry partnerships with this collective goal will drive forward progress. Crucially, those manufacturers who make a positive environmental contribution and can demonstrate this with both product manufacture and operations – are those who will achieve competitive advantage.
Introducing LC Spanrock
Spanrock stone wool insulation boards are designed to provide a non-combustible core material for sandwich panels and other multi-layer systems.
Manufactured using electric melting technology, LC Spanrock is the solution of choice for sandwich panel manufacturers and specifiers looking for non-combustible and sustainable insulation.
SDG: Sustainable Development Goal
Manufactured using large-scale electric melting technology, LC Spanrock has -45% GWP³
compared to standard coal-based technology (A1-A3: production stage in EPDs)
LC Spanrock range
Non-combustible ROCKWOOL boards for high performance lamella core solutions for sandwich panels. Spanrock boards are designed to provide a non-combustible core material for sandwich panels and other multi-layer systems.
LC Spanrock is produced to bespoke specifications to suit exact manufacturer and project requirements.

Benefits of low carbon stone wool in sandwich panels
Choosing LC Spanrock helps to decrease the CO₂ impact of the overall sandwich panel construction.
LC Spanrock also reduces the lifetime environmental impact of a system through circularity in construction as stone wool in infinitely recyclable.
From a performance perspective, choosing LC Spanrock delivers wider benefits in addition to thermal insulation. As a non-combustible product, it withstands temperatures in excess of 1,000ºC and does not emit significant amounts of toxic smoke when exposed to fire. The proven sound reduction properties of stone wool insulation also help to reduce the transfer of external noise into buildings constructed with sandwich panels.
To assist with system specification and construction, full technical support is provided to calculate the CO₂ impact of a sandwich panel using LC Spanrock.
