Ehdotuksen soveltamisala:A method for measuring the insulation performance of building elements such as exterior walls, floors, ceilings, etc. (hereinafter referred to collectively as walls) in the field is described by the use of the temperature distribution in the wall obtained by inserting a temperature sensor in a small diameter borehole in the wall. The measurement method is divided into a quantitative method which measures the thermal resistance with a heat flow measurement, and a qualitative method without heat flow measurement. The methods elaborated in this document are particularly suited to testing the insulation layer in walls. It describes a screening test that requires the drilling of a small diameter borehole through the walls which include an insulation layer. The method is applicable to plane building components with a light heat capacity, such as those in frame structure dwellings. The measured results give the insulation performance at the local measurement points rather than that of the whole panel including thermal bridges such as studs.
