Insulation structures and process for producing them

摘要

The present invention relates to an improved reflective bubble film insulating structures and a process for producing them. The present invention consists in a reflective bubble film insulating structure in which at least one low emissivity surface is directly or indirectly attached to the open cell side of a bubble shaped layer resulting in airtight cells. The resulting structure obtainable according to the process of the invention comprises many individually airtight cells, each one being delimited by a low emissivity surface which thus remains protected from dust and moisture. The reflective bubble film insulating structure according to the present invention may be used not only as an insulating structure as such but also for all structures comprising insulating structures.
