insPIRe® U MAX

Product description

insPIRe® U MAX stands out among GOR-STAL PIR wall panels through its modified polyisocyanurate core with conductivity λ_D = 0.019 W/(m·K) — 14% lower than standard PIR (0.022). Combined with concealed fixing and the GS-Lock joint with factory PUS sealant, the panel offers an optimal mix of thermal efficiency, airtightness and facade aesthetics. At 140 mm thickness it delivers Ud,s = 0.14 W/m²K, matching the requirements of energy-efficient buildings. AVCP level 1 certification confirms detailed production control 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

Applications

• External and internal walls — buildings with high thermal insulation requirements
• Low-energy and passive buildings — skeleton construction with limited partition thickness
• Facades of office, retail and administrative buildings — concealed fixing for an aesthetic facade with no visible fasteners

Technical note: insPIRe® U MAX is a wall panel with concealed fixing — it is not designed to maintain a temperature regime. For cold-store applications use the dedicated panels insPIRe® CH and insPIRe® CH MAX — they have a labyrinth joint that eliminates the thermal bridge, on-site applied sealant and PZH hygiene approval.
