Curb Technologies Roof Curb Products

 

Prefabricated roof curbs offer many advantages over field built curbs reducing installation time and costs by ensuring compatibility between the equipment, the curb, and the roof opening. A wide variety of roof curbs are available, including: flanged, straight-sided, canted, pitched, and ridged.

Construction - Curbs can be provided in either a knock-down (bolt together) form or fully welded, single piece construction.  Knock-down construction will save on shipping costs and fabrication time.  Fully welded will save on-site assembly time.  All welds will be painted with a zinc rich galvanizing compound.  Curbs will be provided with adhesive backed closed cell neoprene gasket.  New install curbs (not adapters) will be fitted with a factory installed pressure treated (PT) wood nailer.  Plenum curbs and adapters will be insulated with 1" x 1.5# density fiberglass duct liner.

Materials - Material can range from 18-10 gauge standard galvanized steel , to equivalent Stainless Steel or Aluminum.

Standard Heights: 12" - 30"

Options include:

Insulation - For knock-down & standard fully welded curbs, insulation will be 1.5" x 3# density rigid foil faced insulation on the interior of the curb.  Plenum curbs that require a cleaner air stream can be insulated with foil faced insulation and joints sealed with foil tape.  

 

Internal Liners - For applications where clean air is paramount, 1.5" x 3# foil faced insulated is used in conjunction with a 20ga galvanized steel liner.  Other liner materials available.  

Coatings - A wide variety of coatings and colors are available.

Decorative coatings are available in many different colors.

Protective coatings are available to provide a selection for most environments.
