Rendabrick Supa

The Rendabrick Supa External Wall Insulation (EWI) system from Alumasc Facades comprises a 2 coat polymer render system – a brick (or top) coat and a mortar (or base) coat – that is applied on to the high performance Alumasc Supa phenolic insulation. Rendabrick can be used with approved resins that allow the finish to be matched to virtually any brick. Rendabrick Supa comprises the most thermally-efficient insulation board, allowing thermal performance to be achieved with the minimum possible construction thickness.

Rendabrick Supa system comprises the following components:

  • Rendabrick Brick Coat
  • Rendabrick Mortar Coat
  • Alumasc Scrim Reinforcement
  • Alumasc Scrim Adhesive
  • Alumasc insulation fixing
  • Alumasc Supa phenolic insulation
  • Alumasc Bedding Adhesive
  • Substrate

Key Features

Rendabrick Supa is suitable for use in low-rise applications. The thermal insulation properties of the Alumasc Supa phenolic insulation board are ideally suited to refurbishment projects due to the lower thickness of the EWI system. The Rendabrick finish is available in a wide choice of colours and resins to achieve the requisite texture to suit the architect’s design requirements.

Key Performance Criteria:

  • Fire performance: Class 0 spread of flame
  • Thermal performance: Typical U Values are:
    • 60 mm Supa insulation ~ 0.28 – 0.30 W/m2K
    • 90 mm Supa insulation ~ 0.20 – 0.21 W/m2K


  • Brick and mortar coats both available in a range of colours
  • Option to apply a resin to achieve specific textures and appearances
  • Weather resistant and remaining vapour permeable
  • Good flexibility provides resistance against cracking and increasing durability
  • Highly resistant to impact damage


  • Masonry substrates
  • New build or refurbishment projects
  • Low-rise properties (i.e. less than 18 m in height)
