Alsecco Alprotect Nova


External wall insulation system classified with European Technical Approval Fire Protection Class A. Alprotect Nova combines unique patented carbon technology and nano-hybrid binders, resulting in a mineral wool external wall insulation system that sets new standards in terms of protection and durability. The system formulations can also be applied with light reflectance values as low as 5%, ensuring most shades of colour including dark ones and even black can be used successfully for the façades finish.

Features/ Benefits:

  • Maximum fire protection.
  • Patented carbon fibre technology.
  • UV stable.
  • Unrivalled impact strength from thin coat system.
  • Highest level of dark colours permissible.
  • 30% application time saving compared with conventionally reinforced systems.
  • Maximum level of crack resistance.
  • Enhanced protection from algae and fungal growth.
