The invention relates to thin, reflective, flexible thermal insulation which can be used in the form of a sheet or lap for all types of buildings and which is suitable for both new construction or renovations, in order to improve the existing insulation. The invention consists of at least three elements comprising an exterior facing (I1) and an interior facing (I3) which are both breathable and reflective and which are separated by an intermediary layer (I2) consisting of a bat that is permeable to water vapour.The aforementioned exterior and interior facings are different and comprise a breathable, reflective, watertight outer facing (I1) and a breathable, non-watertight inner facing (I3) inside the building on the warm side. |
