SIDERISE NXS Firesafe Spandrel Insulation (formerly Lamatherm NXS)

Siderise Group

More Information:

SIDERISE NXS spandrel insulation is a high strength insulation core that offers an unrivalled combination of fire, thermal and acoustic performance, designed for bonding to glass spandrel panels.

It comprises firesafe mineral fibre lamella boards faced on one side with an open polymer filament net fabric to facilitate bonding to the glazed unit, faced with Class 0 foil on the reverse.

NXS insulation presents a compatibility of materials between the rear of the spandrel unit and the firestop system installed at compartment floors/walls. Compartmentation is ensured as interface integrity between the insulation and firestop is maintained.

Supplied to suit the glazing unit schedule or as standard boards, edge rebating/surface profiling is optional. Thickness is determined according to the thermal/fire performance required.

  • Eliminates metal tray lining
  • High compressive strength
  • Firesafe - tested to EN1364-3
  • Maintains integrity at interface with firestopping
  • Ensures compartmentation
