A good rule of thumb would be 3-4 times the r-value below the tubing as above. R-values are cumulative, so if you have a sub floor with floor coverings that have a cumulative r-value of 3 – you should have at least r-9 to r-12 below your radiant tubing.
Staple-up systems may need to run at a higher temperature, it will depend on your radiant designer.
This method is often used in retrofits where joists are accessible as well as many new construction project. The benefits to this hydronic heat installation method are a low materials cost – it is however a more labor intensive installation.
