Summary for decision-makers

Rsoft fire-resistant panel: fire compartmentation and low-carbon performance for buildings

The Rsoft panel is a construction solution designed for fire compartmentation in buildings, offering fire resistance up to REI 240, meeting French standards. Factory-made, it guarantees rapid installation and consistent quality. Thanks to low-carbon concrete and 100% recycled steel, it boasts up to 28% less carbon emissions compared to standard requirements, while also facilitating regulatory compliance and logistical efficiency on construction sites.



Rsoft, a low-carbon concrete fire-resistant panel designed for industrial and commercial buildings. This solution combines high fire resistance with a reduced carbon footprint, meeting the requirements of the RE2020 regulation and fire safety standards.

A compartmentation system that meets fire safety requirements

The Rsoft panel is part of construction systems dedicated to compartmentalization of works, aimed at limiting the spread of flames and smoke between areas of a building. This function is essential in public access buildings (ERP) and industrial buildings subject to strict regulatory constraints.

The solution offers fire resistance up to REI 240that is, four hours. This performance meets the requirements of French fire regulations, particularly those governed by the Code of Construction and Housing and the safety rules applicable to commercial buildings.

"The panels provide effective compartmentalization and limit the spread of flames and smoke."

In practice, this type of product is prescribed by a technical design office or integrated by a project manager into the design of the building's interior envelope.

Industrial prefabrication to control quality

Rsoft panels are factory-made, with a stated production rate of 60 pieces per dayThis prefabrication ensures consistent quality and better control of dimensional tolerances.

The announced technical specifications are as follows:

  • thickness between 15 and 18 cm
  • maximum length of 12 meters
  • delivered items ready to install

This production method reduces risks on site and facilitates implementation by installation teams, particularly in logistics or industrial projects where deadlines are tight.

Application example

On a logistics platform, these panels can be used to separate storage units with different risk levels. Their rapid implementation minimizes site downtime while ensuring regulatory compliance.

A reduction in carbon impact has been announced.

Rsoft stands out for its use of a low carbon impact concrete and100% recycled steelThe objective is to meet the environmental requirements introduced by the RE2020, which requires a life cycle analysis of materials.

According to the data provided:

  • discount up to 28 % OFF compared to a reference FDES (INIES database)
  • discount up to 72 % OFF compared to default environmental data (DED)

"That's 33,56 kg CO2 eq./m² of wall, according to a calculation validated by the firm GINGKO 21."

This approach is part of a carbon optimization strategy for structural and compartmentalization elements, often overlooked in low-carbon strategies.

Calculation methodology and limits of interpretation

The advertised environmental performance is based on a internal calculatorvalidated by an external consultant. This methodology allows the evaluation to be adapted to each project.

However, a caveat is necessary: ​​these results are highly dependent on the calculation assumptions (transport, implementation, lifespan). They should be compared with caution to product-specific EPDs or data from a Life cycle assessment (LCA) prayer.

Furthermore, prefabrication involves logistical constraints:

  • transport of long panels
  • need for suitable lifting equipment
  • anticipation of site access

These factors can influence the organization of the construction site and indirect costs.

An evolution of fire protection solutions in buildings

With this type of panel, the fire protection solutions market is evolving towards products that integrate both fire safety and environmental performanceThis dual requirement is becoming a selection criterion for project owners, particularly in projects subject to labels or carbon targets.

Construction companies and tradespeople working on these projects must now integrate these new constraints into their implementation methods, in line with the specifications of the design offices.

Rsoft thus illustrates a fundamental trend in the sector: integrating fire safety regulations into a comprehensive approach to low-carbon construction, without compromising the technical performance of the structures.
