| Abstract: | Linear thermal bridges in vacuum insulated constructions. Continuously rising demands on the structural thermal insulation of heated buildings lead under certain conditions to high efficient insulation materials, which achieve its efficiency by using the vacuum technology. Inside these elements there is a medium vacuum that has to be durable to guarantee the excellent heat insulating characteristic. For that purpose a non‐permeable enveloping of the core material is essential, which breeds around the element edges increased heat losses, especially referring to the element joints concerning large vacuum insulated areas. This paper quantifies these additional heat losses for different constructions based on measurements. |
