Under slab HVAC/Slab on Grade Construction
Spunstrand® Inc. has been manufacturing under slab HVAC ductwork for over forty years in both insulated and non-insulated forms. Insulated and non-insulated ductwork is available in, but not limited to, standard sizes 2" through 120". Custom sizes, whether they be larger or smaller, round or rectangular, are also available. Rectangular or square duct systems are not usually designed and laid out for underground use except for vertical boot risers. Boot risers are typically sheet metal that can be made out of fiberglass if extremely high water table or corrosive soil conditions exist. Insulation values are available in standard, R-5 and R-10. Greater values required can be easily accommodated. Wall thickness may also be varied to attain greater depths of burial, or to provide better structure for pipe racks and other equipment used for conveyances through the duct system. Spunstrand® fiberglass reinforced plastic duct (FRP) is rated Class 1 and code approved for direct underground burial serving any commercial application which has the supply and/or return air system under the building slab. Typical applications include the following:
