Thermawall TW50 is a high performance cavity wall insulation with a thermal conductivity of 0.022 W/mK. Thermawall TW50 insulation boards are easy to cut, handle and install compared to some other commonly used insulants. They are available in a range of thicknesses.

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. Requirements), ISO 45001: 2018 (Occupational Health and Safety Management Systems), ISO 50001: 2018 (Energy Management Systems. Requirements with guidance for use) and ISO 37301: 2021 (Compliance Management Systems. Requirements with guidance for use). The product is also manufactured in accordance with the Harmonised Standard BS EN 13165: 2012 + A2: 2016 (Thermal insulation products for buildings- Factory made rigid polyurethane foam (PUR) products- Specification).
