Abstract: Non-inflammable, non-flashing foam products such as foam boards, which comprise a layer of a rigid foam of a furfuryl alcohol-formaldehyde containing resin composition wherein at least one surface of said foam product has, as an integral part of its surface layer, porous glass fibre tissue. In accordance with another feature of the invention the glass fibre tissue surface is covered with a layer of an inorganic material such as a silicate. Methods of making these foam products are also disclosed.

Abstract: An improved process for the production of thermoset foams having a predetermined shape by subjecting a reactive amine to a condensation reaction in an enclosed mould cavity, wherein the reaction is carried out under conditions whereby by-product water found during the reaction is substantially free to move out into a space adjacent to and in communication with said foam, and controlling the temperature and care of said foam by regulation of the web bulb temperature of the gaseous mass inside said space. Foam products made in accordance with the process of the invention, e.g. urea-formaldehyde furfuryl alcohol-based insulating foams, are also claimed.
