Rigid Board Insulation | Northern, VA | 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.
