The Airfloor System

A hollow-core floor that heats, cools, and breathes.

Airfloor is a hybrid radiant and forced-air system built into the floor. It uses conditioned air from conventional equipment instead of heated water lines, turning your slab into an efficient air plenum and thermal mass.

The floor build-up

Simple layers. Powerful result.

Sheet-metal forms shaped like mini-igloos hook together across the subfloor, then a thin self-leveling pour caps them. The whole floor becomes a giant, low-velocity duct, so registers can go anywhere with almost no noise.

Key components

Four parts working as one system.

Hollow steel forms

Stamped U.S.-steel forms hook together to create a hollow, pressurized plenum beneath the slab.

Splash box

Delivers conditioned air to the center of the room, where the radiant effect is strongest.

Concrete slab

A thin, self-leveling pour turns the whole floor into a low-velocity duct and heat-storage mass.

Perimeter grilles

Air exits quietly at the perimeter, handling edge loads with mechanical noise below awareness.

How it works

Your floor becomes the duct.

1
Air in, at the center

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

2
Through the hollow floor

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

3
Out at the perimeter

Air exits through perimeter grilles at low velocity, quietly and without drafts.

LEED Certified

Greener buildings
start at the floor.

LEED is the go-to scorecard for green building worldwide. The more a project earns, the higher it climbs. Airfloor is a LEED-certifiable system, and it is already at work inside buildings at the very top of the scale.

LEED rating tiersPoints earned

Every project scores points across the six LEED credit categories, and the total sets its tier. Here are some of the Airfloor projects at each level.

What a LEED rating delivers
Less energy

Buildings that draw less power, season after season.

Less water

Smarter use of every resource, day in and day out.

Lower emissions

A smaller carbon footprint for the life of the building.

Lower costs

Efficient buildings cost less to run, year after year.

LEED credit categories

Where a building earns its points.

Innovation & Regional Priority

Extra credit for fresh thinking and local impact.

Indoor Environmental Quality

Healthier air and steadier comfort for the people inside.

Materials & Resources

Responsible sourcing and less waste.

6
credit
categories
Sustainable Sites

Smarter choices about where and how a building sits.

Water Efficiency

Less water in, less water wasted.

Energy & Atmosphere

Lower energy use and cleaner operation.
