Radiant HVAC · Heating & Cooling

The future of HVAC is hidden in your floor.

Radiant heating and cooling built under the floor inside the slab, engineered for comfort and savings with up to 15% lower energy costs.

One floor, both jobs

One system for radiant heating and cooling.

Instead of heated water lines, Airfloor™ uses conditioned air from conventional equipment. The concrete slab stores and releases energy, so temperatures stay steady and cold drafts disappear, no second system, no coordination headaches.

Notable Projects

Trusted across museums, airports, schools, and civic spaces.

Specified by world-renowned architects and trusted on award-winning, high-profile builds, Airfloor is the choice of the institutions and contractors behind the most demanding landmark projects.

How it works

Your floor becomes the duct.

  1. 1
    Air enters at the center

    Conditioned air from standard equipment feeds a splash box in the middle of the room.

  2. 2
    The floor spreads and stores the energy

    Stamped steel forms under a thin concrete pour create a hollow slab that radiates and stores energy.

  3. 3
    Air returns quietly at the edges

    Air exits through perimeter grilles at low velocity, displacement ventilation with almost no noise.

Airfloor vs. traditional HVAC

Out with the duct,
In with the floor.

Everything overhead ductwork does, with less energy and none of the clutter.

Airfloor™
  • ✓Radiant heating and cooling in one system
  • ✓Up to 15% lower energy cost
  • ✓Registers placeable anywhere, no soffits
  • ✓No drop ceilings; more usable height
  • ✓Near-silent, draft-free comfort
Traditional forced-air
  • ✕Separate systems or add-ons for radiant comfort
  • ✕Temperature swings and cold drafts
  • ✕Duct routing dictates register locations
  • ✕Drop ceilings and soffits eat floor-to-floor height
  • ✕Audible fan and air-flow noise
Why Airfloor?

Save on costs,
Earn more comfort.

Comfort, efficiency, and design freedom in one build detail.

Reduced energy costs

Up to 15% savings from the floor's efficient heat transfer and storage. Your floor holds the energy in the slab instead of blowing it out the ducts, saving equipment runtime and lowering utility bills.

Steady, draft-free comfort

The concrete floor holds heat and cool between cycles, so rooms stay evenly comfortable with no temperature swings or cold drafts.

Better indoor air quality

Fresh air enters low and rises as it warms, carrying stale air and pollutants up and out. You breathe cleaner air, with none of the dust-stirring mixing of overhead systems.

Design flexibility

Place or move air registers anywhere in the floor or walls, with no ductwork dictating the layout. Move walls and partitions later without reworking any ductwork.

No drop ceilings

Air moves through the floor instead of overhead, so there is no ductwork to hide above. Reclaim the height and keep ceilings open and clean, maximizing usable space.

Quiet operation

Air is delivered slowly and evenly through the floor, keeping fan and airflow noise below the level you would notice. Rooms stay quiet and calm.
