Alumasc Pro mineral wool insulation

Alumasc Pro mineral wool insulation is generally specified on both low- and high-rise constructions due to its exceptional performance relating to a range of construction issues:

  • A non-combustible insulation that is A1 rated in accordance with BS EN 13501-1
  • Thermal conductivity of 0.039 W/mK
  • Acoustic properties, typically reducing the weighted sound reduction index by between 5 and 8 dB
  • Excellent environmental properties – containing no gases with ODP or GWP and being recyclable
  • Dual density allows:
    • compression to take up minor imperfections in the substrate; and
    • a higher density outer face that is ideal for the application of external renders and brick slips

Key Features

Alumasc Pro mineral wool insulation can be used with most Alumasc render systems, including Silkolitt Pro, DashAgg Pro and VBriQ Pro in the following applications:

  • New-build or refurbishment projects
  • Masonry, steel frame or timber frame structures
  • Low-rise and high-rise buildings (i.e. greater than 18 m)
