The present invention deals with integrating methods for manufacturing and applying a spacer frame to a glass plate, particularly in the circumstance of increased sizes thereof, of the rigid type, i.e. which profiles essentially are formed by a hollow body having cross section close to the rectangular, micro-perforated in the wall facing the chamber of the insulating glass, where at least the wall facing the outer cavity intended for the secondary sealant is made of solid metal material or with a metal liner, the remaining walls or all the walls being capable of being made of plastic or metal, e.g. aluminum or stainless steel. Certain innovative elements of the devices implementing such methods are also claimed.

Embodiments described include adhesive bus bars for electrochromic or other optical state changing devices. The bus bars are configured to color match and/or provide minimal optical contrast with their surrounding environment in the optical device, provide better adhesion than ink based bus bars, as well as obviate the need to mitigate defects in underlaying layers.

The present invention relates to a method for manufacturing vacuum insulating glass, the method involving applying a vacuum sealant to a first surface of a first glass sheet, the vacuum sealant including a plastic film having a preferably rough surface, placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant, applying a vacuum to an outer surface of the vacuum sealant until a vacuum is formed in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum, and heating the vacuum sealant while the first and second glass sheets are in the vacuum bag.
