Product Description

  • High performance thermoset polyisocyanurate (PIR) insulation - thermal conductivity 0.022 W/mK
  • Clear cavity is maintained - resists moisture penetration
  • Low emissivity foil facings significantly increase the thermal resistance of the cavity
  • Lightweight insulation that is easy to cut, handle and install compared to some other commonly used insulants


Kingspan Thermawall TW50 is manufactured under a management system certified to ISO 9001: 2015 (Quality Management Systems. Requirements), ISO 14001: 2015 (Environmental Management Systems.
