Concrete Floor Insulation Detail

There are two ways to handle insulating concrete floors.

Concrete floor insulation detail.

There are many approaches to insulating a radiant slab but the detail at right shows a frequently used method. Figures 4 9 through 4 11 and 4 15 show configurations with insulation on the exterior surface of the foundation. If concrete needs to be wheeled across the floor simply lay down some. Submitted in 2016 for drc step 3 construction documentation review was an.

If your concrete floor is for industrial or heavy duty applications then any insulation you use needs to have a high compressive strength to take the weight of whatever is above.

Alternative solutions 4 and 5 for continuous insulation of on ground concrete floor slabs. A suspended timber floor is constructed as a timber platform of boards nailed across timber joists supported on sleeper walls and the external and internal load bearing walls surrounding them.

Figures 4 12 through 4 14 show variations where the slab is the primary location for insulation. Although timber ground floor construction used to be a popular method today it is not as common as the concrete alternatives. Of xps or eps insulation at this location. Insofast eps foam panels provides a one step solution to finishing a floor with embedded studs built in to the.

Or as demonstrated here you can cover the slab with rigid foam insulation add two layers of plywood and then add the finish flooring. Detail of insulation on a radiant slab. Typically the insulation would be situated below the slab and below the damp proof membrane for heavy duty use whilst normal domestic buildings would have a. Since the slab will be approximately 5 degrees warmer than the room temperature a 75 degree slab is quite common.

Most builders install 2 in. Thicker insulation is better of course as long as the builder can come up with a detail that allows finish flooring to be installed easily near the exterior walls a task that can be difficult if the foam insulation is exposed at this location. Where the heating is likely to be turned on and off such as in new build domestic properties and a faster thermal response is required the floating floor arrangement of. Insulation below the slab suits continuous low level heating gradually warming the thermal mass of the concrete and sustaining it at a consistent temperature.

Included in this group of details are variations in construction systems insulation location and moisture management strategies. These overall r values do not account for the heat sinking effect of concrete piers where they are included to support a slab footing from below.
