AbstractAbout AuthorsReferences
The article is devoted to the description of comprehensive studies of the operational humidity of thermal insulation boards with a rigid polyisocyanurate (PIR) foam core used in modern roofing systems. Full-scale surveys of 12 flat roofs insulated with PIR-boards realized at least three years ago and located in all three humidity zones of Russia (9 regions) were carried out. After sampling, the values of the operational humidity of the PIR-boards were determined for all the studied objects. It has been determined that the calculated humidity for the polyisocyanurate boards (PIR) faced on both sides with aluminum foil in modern roofing solutions is 2 % (for the operating conditions of structures A) and 3% (for the operating conditions of structures B). The results are proposed to be used in the preparation of Amendments No. 3 to SP 50.13330.2012 “SNIP 23-02-2003 Thermal protection of buildings” in terms of the calculated thermal performance of the polyisocyanurate foam boards with aluminum facing.
