Proteus SP delivers a reliable, adaptable spandral panel solution for window and curtain wall façades across a wide range of projects.

Proteus SP has been fully tested to EN 13501-1 standards, ensuring compliance with fire performance regulations.

For specifications outside the current testing scope, project-specific EN 13501-1 testing can be arranged.

Proteus SP widths vary by material. Refer to the table below for maximum widths by type.

For panel sizes that exceed our standard maximums, please contact our team to discuss bespoke solutions.

Our spandrel panels are designed to deliver exceptional thermal and acoustic performance, tailored to the specific requirements of your project. With a mineral fibre core insulation providing a linear thermal transmission of 0.038 W/mK, the insulation depth can be adjusted from 20 to 200 mm to achieve the desired thermal efficiency.

For acoustic performance, sound reduction can be customised by varying the thickness of the inner and outer skins. Higher dB ratings are achieved by increasing the mass within the panel. Our technical team is available to help select the optimal configuration for both thermal and acoustic efficiency.

Proteus SP is listed on NBS Source, streamlining specification for architects, contractors, and consultants. With access to comprehensive product data, BIM files, and specification clauses, the system is ready for seamless integration into detailed design packages. This supports a smooth transition from concept to construction, ensuring accurate specification and compliance at every project stage.
