HVAC : BROWNIE Blanket

BROWNIE Blanket for HVAC air duct is a formaldhehyde free glass mineral wool blanket used for the sound insulation, thermal insulation and fire safety of ventilating and air conditioning ducts. The insulation is applied for the external insulation of HVAC ducting. These product is available plain to meet specific project requirements. Products are available in a wide range of thicknesses, widths and lengths to suit application.


Insulating the heating, ventilation and air conditioning (HVAC) systems with BROWNIE Blanket can improve the energy efficiency, fire safety and acoustic performance of a building.






  • APPLICATIONS
    Recommended as a thermal insulation for the exterior of HVAC systems or other spaces or surfaces where temperature control is required. The glass mineral wool blanket meets typical industry standards for core and tensile strength, which makes the product more resistant to damage during lamination and installation. The flexible and lightweight features allow the insulation to conform easily around corners and curved surfaces and is readily cut in die presses or with a knife
  • ADVANTAGES
    • Optimal fibre diameter
    • Better fibre network
    • Less dusty and less itchy
    • Low ‘K’ Factor
    • Does not encourage mould growth
    • Excellent acoustical properties
    • Non-corrosive
  • THERMAL PERFORMANCE
    BROWNIE Blanket allows to optimise energy efficiency, prevent heat loss and provide effective thermal insulation. Properly insulated HVAC air duct will be able to limit the heat loss and maintain the desired operating temperature. BROWNIE Blanket is suitable for rectangular ducts of varying sizes. The glass mineral wool insulation complies with ASTM C518 at 15°C mean temperature. Thermal resistance value as high as R1.60 m2K/W
  • ACOUSTICAL PERFORMANCE
    HVAC air ducts should be well insulated to minimise sound transmission and noise emission. Not only an effective thermal insulation, BROWNIE blanket acts as a natural and effective sound barrier. BROWNIE blanket is amongst the most effective acoustic insulation solutions when sound proofing is required. Please contact PGF Insulation representative for further information
  • FIRE PROPERTIES
    HVAC air ducts act as heat conductors during a fire. BROWNIE blanket prevents stops fire from spreading to other compartments within a building. Tested in accordance and comply with(plain/unfaced):
    • B.S. 476: Part 4 Non-combustibility test for materials
    • B.S. 476: Part 6 Fire propagation
    • B.S. 476: Part 7 Surface spread of flame
    • ASTM E84
  • FACTORY APPLIED FACING
    BROWNIE Blanket is available faced with to meet specific project requirements. Products are available in a wide range of facing material, thicknesses, widths and lengths to suit application. Available with the following type of facings:
