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, the product including infrared absorbent and/or reflective elements, and in that the product has a thermal conductivity of less than 30 mW/m.K.

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;.
