Roofing Insulation

PE foam insulation and bubble foil insulation are two different types of insulation materials commonly used for roofs.

PE Foam Insulation

Also called EPE (Expanded Polyethylene) foam or Beta PE. This material may be used for roof, wall, floor, and air duct insulation. PE foam insulation is available in various thicknesses and can be easily cut and shaped to fit different areas of a roof. It is the most popular roof insulation and the most affordable type of insulation. 

  • Features:
    • Cold and heat resistant (-20 to +80 C)
    • Flexible
    • Chemical resistant
    • Moisture resistant
  • Color: white, grey, and pink
  • Laminations: MPET –metalized & polyester



Bubble Foil

Air Bubble with foil insulation or reflective bubble insulation. Multiple air pockets in between help with insulation by preventing conductive heat transfer between the foil sheets. Shock absorbing & vibration dampening properties.

        • Single bubble
        • Double bubble with single or double foil.
       • MPET Aluminum Foil (AZ)
        • Real Foil (RF).



    Considered a premium roof insulation and high R Value (reflective value)

    • Excellent Reflective insulation
    • Lightweight and durable
    • Easy to handle and install
    • Moisture resistant
    • Safe for the health and environment

    The choice between PE foam insulation and bubble foil insulation depends on various factors such as climate, budget, and specific requirements. Other factors such as ventilation, air sealing, and the overall roofing system should also be considered to ensure optimal energy efficiency and performance


    Installation Guidelines: 

    Over the purlins (for new construction)

    1 .Place the wire mesh over the purlins
         2. Install the insulation above the wire mesh and the purlins
         3. Overlap joints by 50mm





    Under the purlins (for existing construction)

        1. Place the insulation perpendicular under the purlins
          2. Place wire mesh under the insulation to support the insulation
          3. Overlap joints by 50mm




    Wire mesh could be used to support the insulation
