Film laminate having at least one diffusion barrier layer and its use in vacuum insulation panels in the construction sector

摘要

The film laminate with at least one diffusion barrier layer for the production of a usable in the construction sector vacuum insulation panel has on at least one surface a polyolefin heat-sealing layer within or on an outer single film or within a coextruded, at least outboard containing a polyolefin layer with an effective amount of a flame retardant or a Mixture of flame retardants is provided. With this film laminate, it is possible to produce vacuum insulation panels that can be used in the construction sector, as they meet the requirements of construction class B2 in a test according to DIN 4102-1.
