Floor Temperature Vs Air Temperature

The floor walls and ceiling all play a part by setting the boundary conditions.

Floor temperature vs air temperature.

According to cmhc canadian mortgage and housing corporation the finished floor temperature should never exceed 85 f 29 c. That sets the gradient in the room. The rising column of air out of the panel radiator counters the cold air flow and the temperature of the surface of the panel radiator is higher than a section of radiant wall and the air space between the back side of the radiator and the wall keeps the temperature that the insulation is working against much lower too. Thermal mass in a heated shop or hangar floor responds rapidly to the change or air temperature when a big overhead door is opened.

The air in the room is only one part of a matrix of thermal flux paths. But don t forget to warm the slab s surface using heat lamps portable heater or hot air blower. Fundamentally the air on the floor will be the temperature of the floor. That 30 degree window isn t very big especially when working outside in the summer months.

In cold weather a concrete slab is almost always colder than the surrounding air and epoxy will immediately take on the temperature of the slab once it is applied. The air on the ceiling will be the temperature of the ceiling. This happens because of the sudden dramatic increase in temperature difference. Extreme hot or cold temperatures will cause the sealer to dry too fast or too slow.

At the optimal temperature 6 of the occupants felt warm or cold discomfort in the feet. The most important temperature to pay attention to is that of the floor not the air. The finished floor surface temperature is what the building occupants feel when walking on the floor affects the rate of heat radiating into the air above the floor and if too high can also become a safety concern. For floors occupied by people with normal indoor footwear flooring material is insignificant.

So this is the temperature range you need to pay attention to. All the heat that has been trickled into the slab over time is released quickly to combat the cold air rolling over the floor. In order to understand how radiant heat makes these benefits possible we must first clarify the difference between ambient air temperature in the home as opposed to the mean radiant temperature. The best range of temperature is 50 to 80 degrees f.
