Abstract

The present disclosure relates to a vacuum insulated glass (VIG) unit frame assembly (10), wherein said vacuum insulated glass unit frame assembly (10) comprises: —a vacuum insulated glass unit (1), and—a frame (20) comprising elongated frame profile arrangements (20a-20d) which frames said vacuum insulated glass unit (1) in a frame opening (21). One or more of said frame profile arrangements (20a-20d) comprises a holding part (28), wherein said holding part (28) holds the vacuum insulated glass unit (2) between first and second holding members (22, 23 28a, 28b,) arranged at opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1), and one or more resilient suspension elements (45a, 45b) is compressed between a first of said holding members (22, 23 28a, 28b) and one of said opposite outwardly facing surfaces (4a, 4b), and wherein one or more resilient suspension elements (45a, 45b) is compressed between a second of said holding members (22, 23 28a, 28b) and the other of said opposite outwardly facing surfaces (4a, 4b). Said compressed, resilient suspension elements (45a, 45b) provides a holding force (F1, F2) towards said opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1) so as to suspend the vacuum insulated glass unit (1) between said first and second holding members (28a, 28b), and each of said compressed, resilient suspension elements (45a, 45b) are configured to be further compressed or expand in response to a thermal deflection of the edge (8a-8d) of the VIG unit (1) due to a temperature difference (AT=71−72) between the two glass sheets (2a, 2b). The disclosure additionally relates to a vacuum insulated glass unit and a retrofitting frame system.
