  • OmniFit® Roll 34 holds an Agrèment certificate by the BBA (under reference number 24/7110) for use as insulation between rainscreen façade systems.
  • OmniFit® products come with a range of sustainability credentials, including lower embodied carbon than alternative low density rock mineral wool products.
  • Multi-purpose product that can be used to insulate a wide range of applications, reducing the need to purchase multiple products.        
  • Rolls are 1200mm wide to allow cutting for installation at varying centre dimensions, providing flexibility on-site.        
  • Designed to friction fit between studs, which prevents air movement and infiltration around the edges, minimising heat loss.
  • Compression packed with more product on a pallet than alternative products.  
  • Manufactured from mineral wool which provides the best levels of sound absorption and reduction compared to other mainstream insulants.
