Abstract:
A method of evacuating an internal cavity of a vacuum insulating glass (IG) window unit, the method comprising:providing first and second spaced apart glass substrates defining an interior space therebetween; providing a passage extending to the interior space between the substrates; providing a plurality of spacers disposed between the first and second glass substrates for spacing the substrates from one another in order to maintain the interior space therebetween; positioning a sealing member over an end of the passage; evacuating the interior space by causing gas and/or air to flow therefrom through the passage and thereafter through spaces defined between deformable sealing elements which support the sealing member over the passage, at least some of the deformable sealing elements being laterally spaced apart from one another so that they do not contact one another.
