Abstract: The invention is directed to a synthetic flashing material, to a method of preparing the synthetic flashing material, and to a method for using the synthetic flashing material, and to the use as insulating material. The synthetic flashing material comprises an amount of polymer material of 75 wt. % or more, wherein the content of metals in the synthetic flashing material is 10 wt. % or less.

Abstract: The invention is directed to a construction material, to a method for preparing a construction material, and to the use of a construction material. The construction material of the invention comprises a perforated sheet of metal and on at least one side of the perforated sheet of metal a thermoplastic layer comprising poly(vinyl butyrate), wherein said thermoplastic layer has i) a modulus of elasticity as measured according to ISO 527 of 0.6-2.0 MPa, preferably in the range of 0.8-1.8 MPa, ii) a shore A hardness as measured according to ISO 7619-1 in the range of 25-65, preferably in the range of 35-50, and iii) an elongation at break as measured according to ISO 527 of 250-400%, preferably 275-375%.
