SIDERISE NXS spandrel insulation comprises firesafe stonewool lamella boards that have been developed as a high strength insulation core for bonding to glass spandrel panels.

The motivation for presenting the SIDERISE NXS spandrel insulation in this application is to provide a "Fire Safe By Design" solution to the problem of curtain wall systems incorporating compressible thermal insulation slabs or combustible foam materials.

Being inherently ‘non-combustible’, mechanically strong and dimensionally stable, SIDERISE NXS spandrel insulation provides the best possible consideration for maintaining system integrity at the junction between the building structure and the curtain wall. However, the actual fire resistance achieved will remain primarily dependent on the curtain wall / frame specification. Information and design advice is available on a project basis.

Note: This product was previously known as Lamatherm Nexus NXS.
