  • Commercial
  • Industrial
  • Education
  • Medical
  • Entertainment
  • Residential

Our stone wool is a leading industry standard when it comes to insulation for fire doors and the best fire door core materials, with fire resilient properties built-in to its smart fibre structure. We work with Original Equipment Manufacturers (OEMs) and door manufacturers to develop bespoke solutions, advise during product testing – and support with best practice expertise.

We call this integrated approach: The Power of &. It’s a philosophy that ensures you benefit from the knowledge, advice and experience of ROCKWOOL Core Solutions experts – transforming your products and end-results.

Why do you need fire door insulation?

Fire doors are a vital part of preventing the spread of smoke and flames in many types of structure, meeting or surpassing local safety standards and giving people time to escape.

Steel doors require the application of fire door insulation to comply with local building requirements, improving the safety of occupants if a fire breaks out. Our stone wool cores can be installed when producing:

  • Standard fire doors
  • Industrial fire doors
  • Locks and frames

Non-combustible, stone wool insulation solutions offer key benefits for manufacturing partners, including:

  • Fire resistance
  • Acoustic performance
  • Thermal properties
  • Dimensional stability
  • Lifetime performance

Design with More Energy Efficiency

The amount of fire door insulation material required will depend on the size, shape and number of doors being produced.

We can provide precision-cut insulation, which is manufactured to the exact dimensions that you need. This ensures maximum performance and the most effective solution for you, whatever your end goal might be.

Our specialists work closely with OEMs every step of the way – from initial innovation and testing through to creating and manufacturing the solutions themselves.

In addition to their fire protection properties, which can prevent costly damage and save lives, installing stone wool cores in doors can also improve the energy efficiency of buildings and structures. These savings are then passed on to occupants.

Sustainability and energy efficiency

Our solutions are designed to help door manufacturers create safe, effective and sustainable products, while increasing efficiencies.

All our customised core insulation is Environmental Product Declaration (EPD) certified[1], meaning it has a clear and transparent product life cycle. Our stone wool can be recycled time and time again to make new products, ensuring that it can be repurposed for new applications.

Stone is one of the most abundant natural resources on the planet, and we ensure that it is sourced sustainably when used in our products. This helps reduce our own carbon footprint when creating our stone wool cores.

We also pride ourselves on a local approach to sourcing solutions. By understanding a range of international markets, we can advise OEMs on the best solution for their project – ensuring less waste and more sustainable outcomes.
