Anticondensation sheet Elkatek Extra L – anticondensation / sheet for waterproofing.
It is used for hydroinsulation of inclined roofs as the anticondensation material. The internal side of the sheet is covered by humidity-absorbing layer, i.e. the sheet may absorb humidity from internal environment. If it is laid above the heating material, the air gap of 50 mm has to be left for ventilation.
