Product description

insPIRe® U is a wall sandwich panel with a polyisocyanurate (PIR) foam core in 1000 mm module, fitted with a concealed fixing system. The λD = 0.022 W/(m·K) coefficient delivers high thermal efficiency in a compact cross-section. The panel achieves fire reaction class B-s1,d0 and fire resistance up to EI 30 (per EN 13501-2). The GS-Lock joint system with factory PUS sealant guarantees joint airtightness at production level — no additional site sealing required. AVCP level 1 certification confirms detailed production oversight by a notified body.

Construction and features

  • Profiled steel facing gives walls an aesthetic appearance
  • Concealed fixing fastener giving facades a more uniform appearance
  • Large lock profile radius keeping the steel protective coating intact
  • Double lock joining the panels ensuring high fire-tightness performance
  • Auxiliary groove easing positioning of the fixing fastener
  • Profiled edges facilitating installation and improving thermal insulation
  • Continuous polyurethane sealant maintaining high thermal insulation. Applied during the production process
  • Aluminium foil preventing water vapour ingress into the polyurethane foam core
  • Rigid PIR foam core with very good thermal and fire properties
