Overview - Air Heated Flooring System
The LEGALETT System is a Pre-Engineered
Frost Protected Structural Concrete
Slab Design used in Residential, Commercial and Institutional
Construction. There are Currently Over 20 Million Square Feet
of LEGALETT Radiant Floor Heating Systems Installed Worldwide.
The Advantage of an air heated floor
- Simple to Install: The LEGALETT system provides for a
faster and more efficient site preparation due to the use
of a flat gravel bed. The simple installation of the LEGALETT
components in the slab also increases installation efficiency.
Permanent edging units, which eliminate traditional formwork,
allows a short construction time.
- Even, Comfortable and Healthy Indoor Living Environment:
Due to the LEGALETT foundation’s heat-storage properties,
an even stable indoor climate is maintained even when there
is a quick change in the weather. LEGALETT ensures warm
and comfortable floors while meeting heating needs (building
The quality of building construction and air changes affect
building heating requirements. Modern construction practices
together with a Heat Recovery Ventilation (HRV) system and
integral in-duct pre-heater offer a very pleasant indoor
climate with the LEGALETT system.
- Low Maintenance Cost: The closed loop pipe system does
not require cleaning or maintenance. The air pipes do not
have the leakage risks of a water system. There is no limit
to the lifetime of the pipe system. The fan and the heating
unit are installed in the closed system with easy access.
This allows for ideal operating conditions during the lifespan
of the heating unit. Should there be a need for servicing,
the unit can be easily repaired or replaced.
- Convenient for the Physically Challenged: The low entry
height of a slab on grade and the heated floor make the
LEGALETT system very convenient for the physically challenged
as well as for small children and infants.
- Heat during Power Outages: The heat storage system is
advantageous in the event of a power outage. Due to the
slab’s ability to store energy, it can release its
large store of heat over a long period of time.
- Construction: As soon as concrete is poured, a Legalett
"Construction Heater" is connected to the pipe
heating system. This effectively dries out the slab evenly,
a process that can continue throughout the construction
period. In addition to extending the construction season,
this has advantages for the entire building process. Painting
and floor laying can be carried out at an earlier stage
than with conventional construction methods. (Traditional
building heaters need not be used.)
