Silkolitt Aricco

Silkolitt Aricco is a decorative rainscreen solution with a Silkolitt+ silicone render finish. The system has been designed for use with timber framed construction, incorporating a fully ventilated cavity. Silkolitt Aricco can be used in conjunction with open or closed timber panels, structural insulated panels (SIPS) or light gauge steel frame. The Silkolitt+ silicone render is applied over the Alumasc Facades by K Rend Aricco render board. This system is therefore suitable for off-site construction as well as traditional on site installation:

  • Silkolitt Silicone Render
  • Alumasc Facades by K Rend Silicone Primer
  • Alumasc Facades by K Rend Base Coat
  • Alumasc Facades by K Rend Scrim Reinforcement
  • Alumasc Facades by K Rend Aricco Board
  • Timber battens
  • Breather membrane
  • Timber frame / SIPS panel

Key Features

Silkolitt Aricco from Alumasc Facades by K Rend is an A2 fire-rated rendered rainscreen system that is suitable for timber-framed buildings up to 18 m in height. The ventilated cavity ensures that the timber substrate is kept dry in accordance with TRADA recommendations. The Silkolitt+ silicone render is applied over the Alumasc Facades by K Rend Aricco render board to provide a clean and contemporary finish with a wide choice of colours and textures available to suit the architect’s design requirements.

Key Performance Criteria

  • Fire performance: A2-s1,d0
  • Vapour permeability of the system allows the building to breath and prevents interstitial condensation


  • BBA Certificate 15/5211


  • Choice of 8 standard colours, but available in any NCS colour reference
  • UV resistant colour pigments
  • Choice of 3 grain sizes – 1.5 mm, 2.0 mm or 3.0 mm – to offer a range of textural finishes
  • High water and dirt repellency that protects the façade against freeze-thaw failure & fungal growth
  • High tensile adhesion strength that prevents delamination and flaking
  • Good flexibility providing resistance against cracking and increasing durability


  • Suitable for use in new build projects
  • Ideal for timber or steel framed construction, including SIPS panels
  • Compatible with offsite / modular construction techniques
  • Suitable for buildings less than 18 m in height
