Alumasc Supa Phenolic Insulation

Alumasc Supa phenolic insulation boards are the most thermally efficient insulation boards commonly used in the UK:

  • Excellent thermal conductivity (between 0.020 & 0.023 W/mK) facilitates more thermally efficient facades or a lower overall construction thickness
  • Green Guide rating of A+

Key Features

Alumasc Supa phenolic insulation comprises a fibre-free rigid thermoset phenolic core that is faced with glass tissue, so that it can be used in a diverse range of external wall applications:

  • Both low-rise and high-rise properties
  • New build and refurbishment applications
