Sealants, vacuum insulated glazing (VIG) units having seals formed from the sealants, and methods for producing the VIG units using the sealants are provided. The sealants include a mixture of glass materials in powder form, a foaming agent in powder form, and a carrier medium. The foaming agent includes carbon black, carbide(s), or a combination thereof. The glass materials have compositions including: 50 to 70 wt. % SiO; 1 to 7 wt. % CaO; 0 to 7 wt. % MgO; 0 to 6 wt. % AlO; 1 to 6 wt. % FeOor FeO; 0 to 7 wt. % TiO; 0 to 16 wt. % RO, wherein R is chosen from the group consisting of Li, Na, K, or a combination thereof; 0 to 1 wt. % SO; 0 to 2 wt. % MnO; and 0 to 6 wt. % SrO+BaO.

Methods, vacuum insulated glazing units produced thereby, and sealants

Methods and vacuum insulated glazing units are provided. The methods include providing a first pane, applying a primary sealant to the first pane adjacent to and along a perimeter of the first pane, positioning support pillars on the first pane, positioning an evacuation tube on the first pane, positioning a second pane on the support pillars, heating the primary sealant with a laser beam sufficient to sinter the primary sealant to form a primary seal joining the first and second pane, evacuating an intermediate space defined between the first and second pane, and the primary seal to produce a low-pressure environment in the intermediate space by drawing gas from the intermediate space through the evacuation tube, and sealing the evacuation tube and thereby hermetically sealing the intermediate space within the first and second pane, the primary seal, and the evacuation tube to maintain the low-pressure environment therein.

Vacuum insulated glazing units and methods for producing the same

Fenestration units and method of operation thereof are provided that allow for use of the fenestration units as nodes of a distributed ledger network. The fenestration units include a communication device configured for communication with at least one remote electronic device, a non-transitory, non-volatile memory configured to store computer readable instructions, and a processor in operable communication with the communication device and the memory. The processor is configured to execute the computer readable instructions to function, through the communication device, as a node in a distributed ledger network by storing a local copy of a distributed ledger on the memory, updating the local copy of the distributed ledger, and distributing the local copy to the at least one remote electronic device in response to updating the local copy of the distributed ledger.
