Clean Air Blanket

As experts in the application of positive pressure technology to the problem of ground gas protection Prestige Air has engineered the Low Energy Clean Air Blanket. Complying with BS 8485 and being recognised as providing very good ventilation, it can be installed as a stand-alone solution or combined with a gas membrane if needed for the higher risk sites. The system operates by delivering a supply of clean fresh air and diffusing it below the floor construction, this disperses any accumulated gas and creates a blanket of air. This provable solution can be installed on both new and existing buildings.


  • Rapid cost effective installation
  • Compatible with all types of construction
  • Ideal for complex substructures
  • Guaranteed underwritten performance
  • Suitable for new and existing buildings
