Siderise curtain wall firestop system named Architectural Record Product of the Year

Siderise system wins Architectural Record award

Siderise has announced that its CW-FS Firestop and CW-CB Cavity Barrier system has been named a 2025 Architectural Record Product of the Year in the Building Systems & Materials category.

The recognition comes from the New York based architecture and design publication Architectural Record, which highlighted innovation, performance integrity and contributions to the built environment.

The award relates to the CW-FS and CW-CB configuration for modern curtain wall façades and perimeter joints.

Siderise introduced the system to the US market in January 2025 after an extended programme of testing, research and refinement.

The company presents the solution as a passive fire protection option for projects that must accommodate façade movement and complex geometry at the slab edge.

Curtain wall firestopping engineered for movement

According to Siderise, the CW-FS and CW-CB combination is built around its Lamella vertical fibre stone wool construction.

This material arrangement is described as maintaining form, fit and fire performance as the façade and structure move over time.

The company sees this behaviour as especially important at the perimeter joint, where deflection and changes in joint width can be pronounced.

The system is intended for use with curtain wall assemblies where maintaining a reliable fire resisting seal under service movement is a design requirement.

Siderise states that the Lamella construction supports long term perimeter fire containment where traditional firestopping approaches may be challenged by movement.

Modular system and technical support package

The CW-FS Firestop and CW-CB Cavity Barrier system is offered as a modular solution to simplify specification and installation.

Siderise manufactures pre cut sections in a range of widths to tight tolerances for repetition in standard details.

The firm also supplies sheet material for adaptation on site when façade joints or cavity conditions fall outside typical configurations.

To support accurate specification, Siderise provides Digital Specification Packs that collate current technical datasheets, certifications, BIM objects and specification clauses.

Project teams can receive detailed technical submittals that align with particular building geometries and stated performance criteria.

Design stage guidance is available for architects, façade engineers and fire consultants working through curtain wall interface details.

The company also refers to site services delivered through the Siderise app, including training, benchmark constructions and installation inspections.

These tools are presented as a way of helping project teams align in service performance with the results achieved in laboratory testing.

Siderise comments on Architectural Record recognition

Brad Davis, Head of Commercial, Siderise North America, welcomed the Architectural Record Product of the Year award for the curtain wall system.

Brad Davis, Head of Commercial, Siderise North America, said: “We are honored to receive this recognition from Architectural Record,”

“The CW-FS and CW-CB system for curtain walling reflects our commitment to engineering passive fire protection solutions that are not only robust and resilient, but that support design teams with transparent, specification-ready information.

“This award reinforces the importance of providing movement-tolerant systems that safeguard perimeter fire containment over the entire design life of the building.”
