WebAug 30, 2014 · For dwellings, the value of fRsi should be greater than or equal to 0.75, so as to avoid the risk of mould growth and surface condensation. For three-dimensional corners of ground floors this value may be reduced to 0.70, for all points within 10 mm of the point of lowest fRsi. This is Part 1, Part 2 to follow… WebAlso, the fRsi calculation is a relative value and therefore has the advantage that it is dependent on the design of the thermal bridge and not on the applied outside and inside air temperatures. If the fRsi value of a thermal bridge is known, then conversely the minimum surface temperature can be calculated with the aid of the air temperatures.
