RECOMMENDED USE
The Millenium synthetic vapour barrier can be glued or laid down with sealed seams on most structural supports such as wood or steel. It can also be adhered or laid down with sealed seams on oxidized bitumen panels, gypsum board or concrete support panels. It is used in the composition of insulated roof systems on commercial, industrial and institutional buildings.
