ABSTRACT:
Laminar insulating foam roofing material (e.g. phenolic resin foam) having improved dimensional stability and which resists warpage when hot asphalt is applied to one surface thereof during installation, is disclosed. A flexible web material such as Kraft paper is bonded to opposing surfaces of the foam material by means of a uniform asphalt coating applied to one surface of the web material, the asphalt being a "sandwich" layer between the insulating foam material and said web material. This material is made by the steps of: (a) forwardly advancing the aforesaid laminar insulating foam material between a pair of opposed rolls; and (b) simultaneously applying a predetermined quantity of a heat absorbing and bonding material to surfaces of two flexible webs on opposing sides of said laminar foam material and bringing said two flexible webs each of which has a coating of said heat absorbing and bonding material applied to a surface thereof, into contact with said opposing surfaces of said laminar foam material at said opposed rolls, such that after said bringing into contact of the insulating foam material and coated web material, said materials bond together to form said assembly.
