A thermal insulation product based on mineral wool, characterized in that the fibers have a micronaire of less than 10 l/min, preferably less than 7 l/min and especially between 3 and 6 l/min, and in that the material has a thermal conductivity of less than 31 mW/m·K, especially less than 30 mW/m·K. The parameters for obtaining this product are in particular the pressure of the burner, the rotation speed of the fiberizing spinner and the daily fiber output per spinner orifice.

Product based on mineral fibers and process for obtaining it

A method determining heat loss coefficient K of a premises, includes: in unoccupied premises, performing a campaign of measurements of at least one temperature inside the premises Tat closely-spaced time intervals over at least two successive time periods Dcorresponding to distinct heating powers Pof the premises; determining temperature of outside air Tat the same closely-spaced times; for each time period D, on the basis of evolution T(t) of a quantity Tas a function of time, selecting a time interval &#x394;tfor which the evolution T(t) is substantially linear, then determining the slope &#x3b1;of the tangent to the evolution T(t) over this time interval &#x394;t, and deducing the value of the heat loss coefficient K of the premises on the basis of the slopes &#x3b1;.
