Poly-kote Lite

The Poly-kote Lite External Wall Insulation (EWI) system from Alumasc Facades by K Rend comprises a high quality polymer-modified masonry paint that is applied over the Alumasc Polymer Render (MR S4) and the Alumasc Facades by K Rend Lite grey EPS insulation board. Poly-kote Lite is a lightweight and cost-effective EWI system with a smooth and durable painted finish.

This BBA-approved system comprises the following components:

  • Poly-kote masonry paint
  • Alumasc Facades by K Rend Polymer Render (MR S4)
  • 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 Lite grey EPS insulation
  • Alumasc Facades by K Rend Bedding Adhesive
  • Substrate

Key Features

Poly-kote Lite exterior cladding system is generally specified because of the economic and lightweight way in which the insulation achieves the required thermal performance on low-rise buildings (i.e. buildings less than 18 m in height) in both new build and refurbishment applications. Poly-kote is a high performance polymer-modified 2 coat masonry paint that can be roller-, brush- or spray-applied onto the Alumasc Facades by K Rend Polymer Render.

Key Performance Criteria:

  • Fire performance: B-s1,d0
  • Thermal performance: Typical U Values are:
    • 90 mm Lite insulation ~ 0.30 W/m2K
    • 120 mm Lite insulation ~ 0.25 W/m2K
    • 160 mm Lite insulation ~ 0.19 W/m2K


  • BBA Certificate 93/2914 PS1


  • Poly-kote masonry paint is available in one of 7 colours as standard
  • Smooth and durable finish.
  • Watertight finish that is vapour permeable when cured
  • Dirt repellent formulation
  • Algae resistant and flexible masonry paint


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