Silkolitt Exicco Pro is an NHBC-compliant drained cavity system that comprises the Silkolitt+ silicone rendered finish to a non-combustible mineral wool insulation. The Silkolitt Exicco Pro system from Alumasc Facades is typically used with new build steel frame constructions.

This BBA-approved system comprises the following components:

  • Silkolitt Silicone Render
  • Alumasc Silicone Primer
  • Alumasc Base Coat
  • Alumasc Scrim Reinforcement
  • Alumasc insulation fixing
  • Alumasc Pro mineral wool insulation
  • Alumasc Exicco Rail
  • Steel Frame

Key Features

Silkolitt Exicco Pro from Alumasc Facades is an A2 fire-rated drained cavity EWI system that is suitable for both low- and high-rise buildings. The drained cavity behind the insulation ensures that any interstitial moisture escapes without detriment to the performance of the system. The Silkolitt+ silicone render provides 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
  • Thermal performance: Typical U Values are:
    • 100 mm Pro insulation ~ 0.30 W/m2K
    • 120 mm Pro insulation ~ 0.26 W/m2K
    • 170 mm Pro insulation ~ 0.19 W/m2K
  • Acoustic performance: Weighted sound reduction index of c. 5 – 8 dB

Accreditations

  • BBA Certificate 17/5471 PS3 – Mineral Wool (Pro) onto steel frame. The system is unrestricted in height
  • BBA Certificate 17/5471 PS4 – Mineral Wool (Pro) onto timber frame. The system is restricted to 18m

Aesthetics:

  • 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

Applications

  • Framed substrates – timber or steel
  • New build projects
  • Low- and high-rise properties in accordance with Alumasc’s High Rise Policy
