DashAgg Lite

The DashAgg Lite External Wall Insulation (EWI) system from Alumasc Facades comprises the lightweight Alumasc Lite grey EPS insulation board with a durable DashAgg stone dash finish. DashAgg Lite is a cost-effective solution for the refurbishment or new build construction of low-rise properties (i.e. less than 18 m in height). The maintenance requirements for the DashAgg Lite system are amongst the lowest of any EWI system due to the robust, hard-wearing DashAgg stone dash finish.

This BBA-approved system comprises the following components:

  • DashAgg stone dash
  • Alumasc Dashing Render (MR S7)
  • MR Scrim Adhesive
  • Alumasc Scrim Reinforcement
  • Alumasc insulation fixing
  • Alumasc Lite grey EPS insulation
  • Alumasc Bedding Adhesive
  • Substrate

Key Features

The DashAgg Lite system has historically been used in refurbishment schemes, particularly those that involve large-scale social housing schemes.

MR S7 was developed by Alumasc specifically for application onto insulation and has a proven track record stretching back over 20 years. A range of stone dash colours are available to provide the building with a clean and modern appearance.
