Fiberglass Board Insulation in Manassas, McLean & Northern VA

Types Of Fiberglass Board Insulation at Southland Insulators

We use two types of fiberglass board insulation in commercial projects: extruded polystyrene board and rigid fiberglass
  • Extruded polystyrene:
    • We install Dow STYROFOAM brand residing board. STYROFOAM contains an average of 20% pre-consumer recycled content. When installed over old siding, STYROFOAM creates a level and solid surface over which new siding can be installed. 

  • Rigid fiberglass:
    • We install JM Insul-SHIELD rigid fiberglass. This product is available unfaced or with facing including FSK-25, PSK, black mat or coated black facing. For more on this product click here.

    • We also install Owens Corning 700 series rigid fiberglass. It is available in a variety of densities, thicknesses and facing options. Types 703 and 705 are available with a factory-applied FRK or ASJ Max vapor retarder facing. For more on this product click here.
