Rendabrick Supa

The Rendabrick Supa External Wall Insulation (EWI) system from Alumasc Facades by K Rend 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 Facades by K Rend 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 Facades by K Rend Scrim Reinforcement
  • Alumasc Facades by K Rend Scrim Adhesive
  • Alumasc Facades by K Rend insulation fixing
  • Alumasc Facades by K Rend Supa phenolic insulation
  • Alumasc Facades by K Rend Bedding Adhesive
  • Substrate

Key Features

Rendabrick Supa is suitable for use in low-rise applications. The thermal insulation properties of the Alumasc Facades by K Rend 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)
