Warming up Concrete Floors

InSoFast panels provide a simple, easy way to insulate cold floors. The attachment studs provide a secure surface to screw the subfloor.

Things to Consider

1. InSoFast panels alone can raise the floor by 2 – 2½ inches which will affect any existing door swings as well as the floor-to-ceiling height.
2. A subflooring layer of at least ½-inch will be required overtop the InSoFast panels.
3. Code requires staircase steps to be all the same height to prevent tripping hazards. Measure your final heights accordingly.
4. Water seeks the lowest point in your home. In basement flooring applications, always make sure you have a working sump pump or back flow prevention system to keep sewage from getting trapped in places you don’t want.
5. Double check your local building codes to determine the allowable live load for construction. See the next section on calculating loads for more information

Calculating Loads

You will need to determine what loading (weight per square foot) is acceptable for your local building codes.

For the most part, live load and dead load values for floor systems are considered “distributed loads.” The total weight is distributed or shared uniformly by the members in the floor system. InSoFast panels are uniform because they have 100% contact with the concrete and subflooring.

Our product testing determined that InSoFast panels can support 13 lbs per square inch of compressive resistance at 10% strain deformation. This equates to 1872 lbs per square foot for the design load, well within most residential construction specifications.
