Insulation Materials
    Insulation Types, Forms & Finishes, Mass Insulation Types
    Fibrous Insulation: Composed of air finely divided into interstices by small diameter fibers usually chemically or mechanically bonded and formed into boards, blankets, and hollow cylinders.
    • Fiber glass or mineral fiber
    • Mineral wool or mineral fiber
    • Refractory ceramic fiber
    Cellular Insulation: Composed of air or some other gas contained within foam of stable small bubbles and formed into boards, blankets, or hollow cylinders.
    • Cellular glass
    • Elastomeric foam
    • Phenolic foam
    • Polyethylene
    • Polyisocyanurates
    • Polystyrene
    • Polyurethanes
    • Polyimides

    Granular Insulation: Composed of air or some other gas in the interstices between small granules and formed into blocks, boards, or hollow cylinders

    • Calcium silicate
    • Insulating finishing cements
    • Perlite
    Forms of Insulation
    • Board: Rigid or semi-rigid self-supporting insulation formed into rectangular or curved shapes.
      • Calcium silicate
      • Fiber glass or mineral fiber
      • Mineral wool or mineral fiber
      • Polyisocyanurates
      • Polystyrene
    • Block: Rigid insulation formed into rectangular shapes.
      • Calcium silicate
      • Cellular glass
      • Mineral wool or mineral fiber
      • Perlite
    • Sheet: Semi-rigid insulation formed into rectangular pieces or rolls.
      • Fiber glass or mineral fiber
      • Elastomeric foam
      • Mineral wool or mineral fiber
      • Polyurethane
    • Flexible Fibrous Blankets: A flexible insulation used to wrap different shapes and forms.
      • Fiber glass or mineral fiber
      • Mineral wool or mineral fiber
      • Refractory ceramic fiber
    Pipe & Fitting Insulation: Pre-formed insulation to fit piping, tubing & fittings
    • Calcium silicate
    • Cellular glass
    • Elastomeric foam
    • Fiber glass or mineral fiber
    • Mineral wool or mineral fiber
    • Perlite
    • Phenolic foam
    • Polyethylene
    • Polyisocyanurates
    • Polyurethanes
    Foam: Liquid mixed at the time of application which expands and hardens to insulate irregular areas and voids.
    • Polyisocyanurates
    • Polyurethane
    Spray Applied Insulation: Liquid binders or water introduced to an insulation while spraying on to flat or irregular surfaces for fire resistance, condensation control, acoustical correction and thermal insulation.
    • Mineral wool or mineral fiber
    Loose fill Granular insulation: used for pouring expansion joints.
    • Perlite
    • Vermiculite
    Cements (Insulating and Finishing Muds): Produced with mineral wool and clay insulation, these cements may be hydraulic setting or air drying types.
    • Flexible Elastomeric Foam
    • Foam sheets and tubing insulation containing vulcanized rubber.
    Insulation Types, Forms & Finishes:
    Insulation Finishes
    : Insulation finishes are important because the ability of an insulation system to perform as designed and specified is dependent upon protection from moisture, weather, chemical and mechanical damage. Insulation can also be used to enhance system appearance.
    Weather Barriers: Protect the insulation from rain, snow, ice, sunlight, ultraviolet degradation, ozone and residues of chemical compounds in the atmosphere.
    • Mastic
    • Metal
    • Plastic
    • Roofing felt
    Vapor Retarders: Retard the passage of moisture vapor from the atmosphere to the interior of the insulation system.
    • CPVC
    • FRP
    • Laminated foil-scrim membranes
    • Mastic
    • Metal
    • Plastic
    • PVC
    • Reinforced polyester resin
    Mechanical Abuse Protection: Rigid jacketing provides protection against mechanical abuse from personnel equipment, machinery, etc.
    • Metal
    • Plastic
    Appearance: Chosen primarily for appearance value in exposed areas.
    • Fabrics
    • Laminate foil/scrim membranes
    • Painted metal
    • Paints
    • PVC
