HEAT REFLECTING VAPOUR CONTROL LAMINATE WITH VARIABLE WATER VAPOUR DIFFUSION
The invention relates to vapour control laminates or VCLs. A heat reflecting vapour control laminate comprises i) insulating laminate means that includes a vapour-permeable carrier layer (1) and a water-tight sealing layer (5) comprising polyamide with variable vapour-permeability and ii) a perforated aluminum foil (3) that is attached to the insulating laminate means (1, 5). The perforations are circular with a diameter in the range of 10 microns to 1000 microns, and follow a pattern with a pitch within a range from 0.5 mm to 10 mm in the direction of production of the heat reflecting vapour control laminate. Due to its micro-perforation the humidity released from the roof construction can penetrate through the membrane, so that the additional thermal barrier, provided by the perforated metal sheet, does not have a negative impact of the humidity transport through the laminate.
