An improved process and apparatus for manufacturing an insulating glass panel assembly having at least two glass panels spaced apart one from the other by and adhered to a moisture resistant sealant composition, said process comprising the steps of (a) applying said sealant composition to a portion of at least one of said glass panels; (b) suitably positioning said glass panels one to the other in spaced apart relationship with said sealant therebetween; (c) heating said sealant to effect adhesion to said glass panels; and (d) cooling said sealed insulating glass assembly; the improvement comprising selectively heating the sealant by selectively irradiating said sealant at an effective sealant absorbing but relatively low glass absorbing infrared wavelength selected from 0.8 - 1.3 microns, preferably, 1.1 - 1.2 microns, to effect selective heating of said sealant by said radiation. The process and apparatus obviates the need to provide a temporary aperture for air movement into and out of the air space in the assembly during manufacture and, accordingly, reduces expensive labour, time and storage costs. The invention further allows for large lite assemblies to be treated.
